Midas Pattern Co. Ltd have spent nearly 40 years developing and refining our unique system of composite resin, reaction injection mould tools (Midas’ MRIM RIM Tooling) in order to satisfy our customers’ exacting requirements.
Our unique tooling system enable us to mould even the most complex and precise parts with ease, allowing us to assist a range of different industries. But how exactly can our methods support your complex part requirements?
Experts in Polyurethane RIM Mouldings
Our polyurethane RIM moulding process mixes both the polyol and isocyanate components of the PuR resin together, creating an exothermic reaction to form a thermosetting polyurethane resin (PUR or PuR).
These fully cured parts cannot be re-processed in the same way, but they can be repaired, refurbished, modified, rebranded and repainted to fit updated marketing.
Our RIM produced parts can also be customised in different colours, finishes and textures, on a batch-to-batch basis or to suit special requirements. Get in touch to discuss your specific requirements.

The Benefits of Polyurethane RIM Mouldings
A much faster and more cost-efficient solution when compared to Injection Moulding - Used to manufacture parts as heavy as 30kg and up to 3m in length as single items, reducing the requirement for multiple components.
Flexible - Is able to accommodate varying wall sections with no risk of sink or distortion, as well as the encapsulation of threaded inserts, studs and magnet keepers to help reduce risk and improve manufacturing efficiencies.
Excellent tolerance control and precision between mating mouldings - Made possible due to extreme in house process control when casting the polyurethane material, increasing batch-to-batch consistency while reducing distortion and variation.
Using Our MRIM™ Tooling for Your Complex Part Requirements
Our bespoke MRIM™ tooling is renowned for being a fast and accurate, yet low-cost solution, particularly well-suited for the creation of large, complex or “difficult” mouldings. It can also suit both small-to-moderate production runs (1 off to 2000 off per annum) and prototyping requirements when required.
This tooling entails a manufacture of a composite resin mould tool directly from CNC-machined master pattern, allowing even the most complex forms to be produced accurately, quickly and competitively. This also allows for a tool lifespan of over 10 years or a minimum of 5,000 cycles!
The intricate nature of our MRIM™ tooling allows us to provide our clients with PU mouldings featuring elements that usually need to be post machined, such as vertical faces, undercuts, re-entrant features, holes, counterbores, countersinks etc.
Polyurethane Mouldings for Life-Enhancing Industries
Our polyurethane RIM mouldings can create precision parts that offer structure and confidence when it counts the most, working to form parts with tight tolerances and complex structures.
Our MRIM™ tooling is largely suitable for the creation of low volume, high-quality PuR mouldings, often required for medical and medtech products as well as scientific or highly finished enclosures or housings.
These safety-conscious industries demand compliance against all regulatory standards, as well as UL94 V0 flammability ratings and the option for RFI/EMC shielding - all of which we can offer using our extensive in-house facilities.
