From Prototype to Production: Our Custom Part Process
When a part is unavailable, too expensive or keeps failing, a custom part can solve the problem for good. Here is how custom mining parts manufacturing works at Mining Parts Australia, from first conversation to full production.
Step 1: Understand the Problem
We start by understanding what the part does, why it is failing or unavailable and the conditions it works in. A sample of the existing part, photos, drawings and measurements all help.
Step 2: Design and Material Selection
Design input
We review the design for strength, fit and manufacturability and suggest improvements where they make sense.
Material choice
We select a material to suit the job, whether an engineering thermoplastic or a urethane grade.
Step 3: Prototype
A prototype lets you test fit and function before committing to production tooling. Learn more about prototyping methods.
Step 4: Tooling
For injection-moulded parts, a production tool is designed and made. Our team has experience in tool design for both plastic parts and integrated plastic and metal assemblies.
Step 5: Sampling and Approval
First-off parts are checked against the specification and trialled on the equipment where possible. Once approved, the design is locked in.
Step 6: Production and Supply
We manufacture in volumes from a few hundred to millions of units, with consistent quality control. Ongoing supply agreements keep stock available when you need it.
Real-World Example: The ROLLSAFEGUARD
Our ROLLSAFEGUARD started as a solution to repeated check valve damage on jumbo rollovers. It was designed and made in-house to fit existing mounting points without modification.

Frequently Asked Questions
How do I start a custom part project?
Contact us with a sample, photos, drawings or measurements of the part and a description of how it is used and why it is failing.
Do I need a drawing to get a custom part made?
No. A sample of the existing part, photos and key measurements are often enough to get started.
Can you improve on the original part design?
Yes. We review designs and materials and can suggest changes to improve wear life or fit.
What quantities can you produce?
Mining Parts Australia produces custom parts in runs from a few hundred to millions of units.
