Custom Shims Designed & Cut In-House
Australia’s Only In-House Shim Importer & Cutter
At Mastercut Technologies, we specialise in manufacturing high-precision custom shims for a wide range of industrial applications.
Whether you're aligning shafts, spacing machine components, or correcting machinery levels, our expertly crafted shims are trusted across Australia’s mining, manufacturing, energy, and heavy equipment sectors.
As the only Australian provider that imports and cuts shim materials completely in-house, we offer unmatched speed, flexibility, and precision. From one-off prototypes to high-volume orders, we deliver reliable, burr-free shims that perform under pressure. We’re also known for our rapid turnaround times, especially for urgent breakdown or maintenance jobs.
And if you’re looking for fast, ready-made options, we also stock a full range of standard-sized stainless steel shims available for quick dispatch.
What are custom Shims?
Shims are thin, flat pieces of material used to fill gaps, align components, and ensure accurate spacing in mechanical assemblies. Though small, they play a big role in maintaining operational performance, extending equipment life, and preventing costly failures—especially in demanding environments.
Standard shims typically come in fixed shapes and sizes like washers or rectangles, and are ideal for common setups or quick repairs. However, when the space, shape, or load conditions vary—or when precise tolerances are required—custom shims are essential.
Custom shims are designed for an exact fit. Whether it’s a slotted design for easy installation, a tabbed profile for secure placement, or a multi-hole layout for evenly distributed load, these shims are tailored to your application and built to function exactly as needed.
Custom Shim Packs – Built to Your Specs
Every custom shim pack is made to order and tailored to your requirements. Whether it’s for precision alignment, vibration isolation, or equipment maintenance, our shim packs are ready for installation the moment they arrive—no cleanup or modification required.
We work with a wide range of materials, including:
- Stainless Steel (304, 316)
- Mild Steel
- Brass
- Copper (on request)
- Aluminium
We can produce virtually any profile or geometry you need:
- Washers and round discs
- U-shapes and horseshoe profiles
- Slotted designs for easy fitment
- Tabbed or notched edges for alignment
- Multi-hole and compound configurations
- Complex shapes based on your CAD drawing
Each pack is:
- Laser, waterjet, or chemically etched depending on the material and design
- Supplied with a burr-free, polished finish
- Grouped, labelled, and heat-shrink packed for easy handling
- Available with material certificates and conformance reports on request (API 686 compliant)
- Delivered with serial numbers or part markings, if required
Quality You Can Trust, Every Time
We take quality seriously at every step of the process. As an ISO9001 certified manufacturer, you can trust that what we produce meets high standards—and that we check and inspect thoroughly before it reaches you.
If your project requires detailed documentation, we’re able to supply full certificates of compliance, material traceability, and precision measurement reports. Everything is done in-house, giving you confidence in every cut.
File Handling Made Easy
We’re set up to work with a wide range of digital design files. Whether it's standard CAD formats like .DXF and .DWG, or Illustrator files, we’ll take your drawing and turn it into a shim that fits your machinery perfectly.
Don’t have a file ready to go? No problem. Our in-house CAD team can assist by creating the required designs for you. Where possible, we’ll also nest multiple parts together to maximise material efficiency.
Smart Packaging and Fast Delivery
Once your shims are cut, we take just as much care in how we pack and deliver them. Each part is cleaned and deburred, then grouped by type and thickness to make your job easier when they arrive.
We label everything clearly and use heat shrink packaging to keep parts secure and protected during transport. This means they’re quick to identify and even easier to install when the time comes.
And when time is critical, we’re ready. Our team is used to working to tight timeframes, and we offer express delivery services to help you stay on schedule.
We ship to anywhere in Australia and can also ship internationally if required.
Need Standard Shims? We’ve Got Those Too
For jobs that don’t require custom shapes, we also supply a full range of standard stainless steel shims, available in common sizes and thicknesses. These are ready to go and can usually be cut, packed, and despatched the same day
