If you are stuck at home in isolation this is an awsome oportunity to build that project that you have been thinking about.

How to order your cutting and tapping service online

If you don’t have the equipment to process your profile accurately, we can take care of all of you cutting drilling and tapping requirements. Just follow the steps in this article to get your project underway. Check out this blog on how to get the most out of your profile  

Design your project carefully

This is the most important step and will make or break your project before you make your first cut.

You don’t need an expensive CAD system, many of our customers have built amazing projects using a hand-drawn sketch. Just take your time and do this properly

If you find that your project is more complicated than you expected or even if you don’t have the time, we can take care of your design requirements.

We use Solidworks and can provide 3D models, bill of materials and IFC drawings.

Contact us for a free consultation.  

Cut your material.

Before you cut anything, make sure that you fully understand how to join T Slot Extrusions (did I mention that its important to design your project carefully)

T-Slot profile saw

Once you are confident that your cut list is correct you need to work out how much aluminium you are going to need. We strongly recommend that you use a cut list optimiser.

This will help you eliminate unnecessary wastage.

Use a new optimiser page for each size of profile if you are ordering multiple sizes.

This will help you eliminate unnecessary wastage.

You can email a pdf copy of this list to us or just enter your requirements directly into the cut list form on our website.

Remember that the longer the profile the more expensive it is to transport. Usually it is more cost-effective to cut the profile before delivering it. Once we know the delivery address and the length of the parcel we can provide a quote for delivery.  

Drill and tap your profile.

Machining T Slot Aluminium Profile

Drilling and tapping is the most time-consuming part of the project and requires the correct equipment in order to produce a high quality end product. In order to get this right we need as much accurate information as possible.if you have access to a CAD system we can use Solidworks models or step files to work out where you need the profile drilled or tapped. A simple hand-drawn sketch is usually all we need as long as it contains all the relevant dimensions we need. You can upload your drawings here on our tapping and drilling page.

If you need more information please see these useful pages for information about Extrusion taps, Fixing plates, Linear joints, Angular joints, Cube joints, Pawl clamps

Why do we use an extrusion tap to form threads?

In the right application, using a thread forming extrusion tap can improve quality and productivity.

The most commonly accepted method of creating a threaded hole is to use a cutting tap

However, you can often produce better threads using a forming or extrusion tap.

The main advantages of using forming taps rather than cutting taps can be summarised as follows

  • No material is removed during thread forming instead the material is displaced to form the thread.
  • The thread formed has a smoother burnished finish.
  • The threads produced are stronger.
  • Thread forming taps are better suited for use in holes that are interrupted by longitudinal slots such as the ones commonly found in some Aluminium T Slot Extrusions.
  • Actual thread sizes are usually closer to gauge limits
  • The life expectancy of the tool is usually 20 times longer for an extrusion tap.
  • Higher spindle speeds used with extrusion taps translate into higher productivity when cutting threads.

The Framework for your next project

Build it easily with T Slot extruded Aluminium Profiles and accessories

T-Slot Aluminium Profiles

Extruded aluminium t-slot profile is an ideal material to create a frame to support and house machinery of all types.

Using extruded t-slot aluminium profiles and accessories makes it easy to manufacture all kinds of machine frames. The system is highly versatile and can be customised to suit your machinery. No matter how simple or complex the structure, the inherent versatility of t-slot profiles allow us to customise an exact solution for your machine.

We can engineer a machine frame to suit your requirements using our 3D CAD software.  Alternatively, you can provide us with your design that we can build your project for you according to your plan.

User-friendly construction.

This system is cost-effective and easy to use 

T-slot profile is both lightweight and strong.  Unlike steel, it doesn’t need welding so is not susceptible to distortion during construction or at installation. There is also no requirement for surface treatment such as painting after assembly.  As a result hot work permits and similar workplace health and safety paperwork is not needed should site modifications be necessary.

Because the T-slot system is so highly versatile modifications can be easily carried out as you go making it perfect for prototyping or where highly customised solutions must be put in place.

Now this is living

  This is how you experience the great Australian outback on a budget !

T Slot Aluminium
DIY camper trailer

When my good friend James told me that he had ripped his homemade camper trailer apart and wanted to re-construct with our aluminium extrusion I was impressed with his level of motivation. James had built his camper a few years back in a bit of a hurry when he and his wife had decided to take a year off and tour around Australia with their 2 kids. Although the camper was built on a bog-standard box trailer on a shoestring budget it had served them well and, in the process, he had built up a good understanding of what he needed to improve on. But stripping it down was a pretty bold move. When he casually mentioned that he was leaving for a trip to the Simpson desert in 2 weeks’ time I thought that he had overestimated his ability to get the job done.

Now this is living - aluminium extrusion

It was obvious from the start, that James had been studying our catalogue. He knew exactly what he wanted, and he presented me with a detailed cut list and a list of accessories. Soon his camper trailer began to take shape in his garage. Every evening after work for the next two weeks he could be found toiling away in his garage.

Now this is living - aluminium extrusion

True to his word, within two weeks he was saddled up and ready to head off into the wilderness. Although I did hear tales of him spending the first few nights on the road with his tools doing some last-minute alterations I was still impressed with the speed with which this project came together.

What an epic journey for this adventurous family. I’m sure that there will be plenty of modifications to this camper over the next few months and I am looking forward to the next adventure. It is always rewarding when our customers and friends share their experience with us.

Using aluminium composite panels in T slot builds.

T Slot Aluminium
Workbench Workstation

When you are building with T Slot extrusions, aluminium composite panels are a cost-effective way to enclose your structure. 

You can improve the rigidity of your structure or provide an airtight enclosure using composite panels in your build 

This is useful for building 

  • 3D printers 
  • Clean rooms
  • Cupboards
  • workstations
  • CNC machines 
  • Trolleys 
  • Exhibit display stands

Enclose the panels within the T slot or fix them to the external face using the T slot to hold the nuts required.

Enclosure frame

Composite panels provide an excellent base for graphics and signs to be installed.

Including the panels at the design stage saves time when assembling your project.

Clear acrylic, aluminium sheet, plywood and a number of other materials can be used in the same way.

Custom Made Workbenches and Workstations supplied by GAP Engineering.

A suitable working environment is crucial in achieving your production goals.

Custom Made Workbenches and Workstations supplied by GAP Engineering. - aluminium extrusion

A poorly planned workstation can have a significant negative impact on any of the following:

  • Workplace health and safety
  • Quality control
  • Productivity
  • Profit margin 

What to look for in a well planned and designed workstation

1. Correct work height

 An operator’s arms should be below shoulder level
 Precise tasks: 50mm below the elbow
 Light assembly: 50 -100mm below the elbow
 Heavy work: 100 – 200mm below the elbow

2. Equipment adjusted to suit the task 

All aspects of the workstation; seat height and angle, footrest height and angle, should all be adjusted to correct values.  So too, work pieces, parts containers, and tools should all be in their correct places.

Profulium Aluminium profile workbenches
Tools laid out easy to see and access

3. Well laid out workpieces and parts containers

Optimise container layout to reduce wasted motion and speed up throughput.  This includes ensuring the heaviest and/or most used parts are placed in the closest containers.  Optimal container layout is within a 400mm radius, as measured from each shoulder

4. Correct working area size

Maximum grab area: 540mm radius, measured 160mm to the left and right from the centre line and the front edge of the worktop.  Optimum grab area: 280mm radius, measured 160mm to the left and right from the centre line and the front edge of the worktop.

5. Consider the operators’ field of vision

Operators should be able view the work piece without excessive need to turn head or eyes.  A 15° view angle requires no head or eye movement to grab parts.  A 35° view angle requires only eye movement to grab parts.  Viewing distance to screen or a drawing should be between 350mm and 750mm.

6.Select suitable light intensity for the task

 Standard assembly tasks: 500 — 750 lux
 Complex tasks (e.g. electrical assembly): 1000 — 1500 lux
 Delicate and/or critical work: 1500 — 2000 lux

7. Do not work above the heart

Work tasks are best kept at a height below the operator’s heart.  This is to avoid undue restrictions on blood circulation.
Keep static holding during assembly to a minimum as it increases muscle fatigue, and, can sometimes lead to blood circulation problems.

8. Load bearing capacity

This may seem such an obvious consideration, but it is surprising how often a new bench or workstation starts to buckle or fail under the load of the new work process.

9. The durability of the work surface           

Another seemingly obvious one, but again there are more than a few workstation benches out there with a sheet of stainless steel screwed down to the original particle board bench top.  More expensive as an add-on than if part of the original design.

In order to make the most of available space and resources, it is also important to consider if it would be beneficial to integrate one or more of the following into your workstation system.

  • Power and data
  • Lifting units
  • Mobile parts shelves and trolleys
  • Drawers and storage compartments
  • Parcel chutes
  • Lighting
  • Linear rails and guides
  • Adjustable footrests
  • Monitor arms
  • Compressed air outlets
  • Shelving systems
  • Tote bins
  • Integrated machinery such as robots or conveyors
  • Safety guarding

How to create a strong join in aluminium t-slot extrusion

We understand that you need to save time and money.  So we would like to show you the most cost-effective way to join extruded aluminium t-slot profile. 

Aluminium T Slot extrusion joint

This is the standard joining method for T Slot Aluminium profile and is surprisingly quick and easy.  In less than 60 seconds one can make a strong join between aluminium t-slot extrusions at a minimal cost.  There is no complicated machining involved.  There are no special tools required.  This can be done on-site without welding or the need for a hot work permit.  

Follow this step by step guide to learn how.

** For your own safety sake, please ensure that you follow all relevant safety procedures and guidelines when operating machinery and using power tools. **

T-Slot profile saw

1. Cut your profile to length.

It is important to make a clean accurate cut because this will impact the quality of your finished join.  Use a good quality saw with the correct type of blade for cutting aluminium.  A good supply of quality cutting fluid will be needed to prevent profile and blade overheating.  Make sure that your profile piece is securely clamped.  To save you time we are able to cut your aluminium profile to length for you.  You simply need to provide us with a cut list. 

T slot Aluminium extrusion drill and tap

2. Tap the core hole in the end to be joined.

This is a very simple and quick process as the core is perfectly formed to the correct size for tapping.  Use an M8 tap for slot 8 series, or M6 for slot 6 series, profiles.  Using an extrusion tap and the correct cutting paste will ensure a perfect thread will be formed.

GAP T Slot Aluminium drill jig

3. Drill an access hole for your hex key.

Use a drill press, or drill guide, to accurately position the hole and not damage the profile piece.  We generally use a drill press specially set up for this job.  The drill guide is only really useful for when you don’t have a drill press or when you’re on-site needing to drill a hole.  

T slot aluminium cap screw and washer for junction

4. Fit a low profile cap screw and washer to the hole you tapped earlier.

Aluminium profile system

5. Slide the washer and cap screw head into the slot.

Move it into the slot so that the cap screw lines up with the hole drilled earlier.

T Slot Aluminium Profile joining system

6. Using the access hole you drilled earlier tighten the cap screw with your hex key.

Make sure that the two sections of t-slot are perfectly aligned as you tighten up the join.

You have now created a strong join in aluminium t-slot extrusion.

There are several alternative methods of joining T Slot aluminium profiles.  These alternative methods are useful under different circumstances.  If you would like more information please check out our blog.  We have articles about through body joins and joins using clamping plates

Get your electricians better organised this year

Electrical wiring  in a factory environment can be extremely complicated.  This is especially the case if you aren’t properly organised. 

Firstly you need to have a whole lot of rolls of wire, of different types, on hand.  Next, there are all the different fittings and connectors that go on each type of wire.  And that’s before you’ve even started organising tools to suit the schematics of the job at hand.

As we all know, the most expensive component of a job is often the labour cost.  So, having all your materials and tools properly organised, for your staff, can decrease your costs.  For that reason, a properly organised work place can help ensure that your staff can be at their most productive in a safe working environment. 

Therefore, creating your own custom workstations can improve quality as well as productivity of your staff.  We can custom build a work bench to suit almost any workstation layout that you can think of.  That may seem a big boast, but we have an extensive range Alusic extruded aluminium t-slot profile and accessories at our disposal.  Also, we have people experienced with designing and building using these t-slot profiles.

Do you know what Aluminium T-Slot extruded profiles and accessories can be used for ?

Actually that question is probably a bit harder to answer than it would initially appear.

We are fortunate to work in an industry where we are exposed to a lot of highly creative and intelligent people.  As a result we constantly encounter people who are using our products in new and interesting ways.

Do you know what Aluminium T-Slot extruded profiles and accessories can be used for ? - aluminium extrusionNo matter how complex or unusual your project, chances are that t-slot extruded aluminium profile will be able to play a role in helping you achieve a cost effective and practical solution.  This applies to a large range of projects.  From material handling to automation, packaging to prototyping, and everything in between.  It’s very common to see t-slot aluminium profiles being used in the modern industrial environment as well as in other areas.

The main motivation for using T-Slot is that it greatly reduces the amount of time required to build.  This is because you don’t need to prepare and weld joins.  You also don’t need to prepare and paint a whole structure once you have built it.  Both welding and painting are messy, expensive and time consuming.  If you need to weld or paint in a sensitive environment the noise, fumes, heat, or just plain dirt generated can become a considerable problem.

How to keep up with the pace of change in the modern industrial environment.

You are probably aware that we are in the middle of the fourth industrial revolution.

The fourth industrial revolution is characterised by a fusion of technologies that is blurring the line between cyber and physical systems

The first three industrial revolutions transformed and revolutionised our society and with each stage the world fundamentally changed around us.  Technological evolution speeds up exponentially as each generation of technology improves on the last.  As change becomes more rapid it is becoming increasingly important to be aware of this when installing infrastructure such as factories.

There are some key areas where GAP Engineering can help improve your ability to keep pace.

CAD design 

Sliding Trolley

CAD models play a crucial role in the planning and implementation of modern factory installations.  It is becoming more common for the interior of entire buildings to be 3D scanned so that a complete CAD model of the entire workplace can be created.  Every detail such as work flow, positioning of safety fencing, height restrictions and positioning of equipment can be thoroughly analysed before any other steps are taken.

CAD models for all our profiles and accessories are available for download in several CAD formats.  If that is not of use to you, we provide a CAD design service.

To access our CAD files please complete this Confidentiality agreement  so that we can send you the CAD files you need.

Rapid prototyping 

How to keep up with the pace of change in the modern industrial environment. - aluminium extrusion

There’s an old saying, “The more things change the more they stay the same”.  So, keeping up with the changing industrial environment there will always be a need to convert new ideas into new physical functions.  That will normally require new machines.  To build new and better there will almost always be a need to build prototypes.  As the rate of change increases you would expect the pace of prototyping to increase correspondingly.

This is where products such as t-slot extruded aluminium profiles play a vital role in allowing for the construction of workable prototypes that can easily be redesigned and modified.  Furthermore using t-slot profile, many components can be recycled for other prototypes with minimal for cutting or welding of metal.  We stock over 60 varieties of t-slot profile as well as a large range of joining and other accessories.

Adaptable cost effective machine frames.

Because it can be modified without the use of metal cutting, grinding, welding or painting the Alusic t-slot aluminium extrusion system can save a lot of money when there is a requirement for modifications and improvements to machine frames.  Because it is usually more cost effective to use this system for the initial construction it really is the best solution available. It is very easy to add additional components or frame work members with minimal impact.

design your project thoroughly before you start cutting

If your project is relatively complex and you don’t have access to a CAD drawing system consider employing the services of a CAD designer. Planning your project properly will greatly increase the quality of your project and reduce the overall cost. Planning includes drawing up an optimised cutting list

Optimise your cutting list

Failure to do a thorough optimised cutting list is almost guaranteed to result in excessive wastage.

When you have a large number of pieces to cut, it can become very complicated calculating an optimised cutting list it.  Fortunately, there are a few free, and online resources available to help you out. 

For example, a quick web search found Cut list optimiser which is suitable for 1D bar optimisation.  The web site requires that you sign up to a free account so that you can save your projects for later review.  Before deciding to sign up, you can look at one of their demo’s or go straight to their offline project page.

Obligatory disclaimer:  Please note that we do not recommend any particular solution in preference to any other.  You are free to choose what suits you.  You can even create your own spreadsheet to assist you in your calculations.

Once you have your cutting list, you can send us a copy so that we can accurately cut it for you.  We can also arrange delivery if you need.  Please note that delivery costs vary considerably depending on size, weight, and delivery address.  The most expensive being full 6m lengths.

Cutting, drilling and tapping

Ensure that you use a very good quality saw that is specifically configured to cut aluminium .

Cut lengths that are inaccurate or not completely square will prevent you from achieving the best possible results.

Use an extrusion tap to create the threaded ends as well as a quality tapping gel that is formulated to cut aluminium. An extrusion tap differs from a regular tap in that it does not remove any material in the process and also hardens the surface of the thread. this results in a stronger thread and consequently a more reliable end product . Also, ensure that your taps are perfectly aligned to the core centre of the extrusion.

When drilling through the centre of the extrusion use a drill press or drilling guide to ensure that your holes are accurate and that your drill does not damage the edge of the slot.

When you require a conveyor system you need to consider a lot more than just the conveyor itself.

These are some of the factors you may need to take into consideration

    • How you are going to integrate a conveyor system into your current infrastructure
    • How can ensure that it is safe to operate
    • How can you minimise disruption to your production while it is installed.
    • How easily can you make modifications to it.

Our extensive range of t-slot extrusions and accessories will help you to overcome these and many other challenges.

Because our products are so versatile and adaptable you will be able to design and construct your conveyor system and any associated equipment such as work stations or guarding out of the same easily integrated components

Over 80 Profile types and a full range of accessories 

Gap Engineering Pty Ltd are suppliers of extruded aluminium profiles, fittings, and accessories from the Italian Manufacturer Alusic.

The Alusic profile design is like an industrial “meccano” system.  It can often be used as a direct replacement for welded steel.  So, if you can build it in steel it can usually be built with aluminium profile in less than half the time.  Dimensional tolerances of an aluminium profile structure are usually less than half those of a typical welded steel structure.

Also, aluminium profile structures don’t suffer the distortion and warping typical of welded steel structures.  Added to that, aluminium profile usually doesn’t need special surface treatments or painting to protect from corrosion.  Another benefit of aluminium profile is that hot work permits on site are not required.  All this adds up to lower labour costs, lower work place health and safety costs, and the all important better customer satisfaction.

Whether you are you a manufacturer, an end user, a re-seller, or a hobbyist, GAP Engineering are here to help.

No order too big or too small

We can supply in bulk or in small quantities.  If we don’t have it in stock we can get it in for you.  

GAP Engineering can supply extruded profiles and accessories directly; including cutting / drilling / tapping to your sizes.  Also, we can undertake the complete assembly of frames and systems according to your design requirements.  We can even do the design if you don’t have the facilities.

Connections in less than a minute

Typically the Alusic connector represents a significant time saving over competitors’ connection systems.  Testing has shown a 300% to 500% time saving over competitors’ systems.  This time saving when multiplied over a large project or on multiple assemblies can realise substantial cost savings and production benefits.
