MRT Castings Ltd - MRT Castings Ltd

MRT is a specialist gravity die casting, sand casting and high pressure die castings company.

We offer the complete solution for your non-ferrous component requirements. We supply high quality cast products ready for use in the shortest practical lead times. We offer a one-stop shop by machining, finishing and assembling cast components ready for your production line. 

Our Services:

• high pressure die castings
• gravity die casting
• sand casting
• toolmaking
• CNC machining
• surface finishing
• assembly

Let MRT provide you with the complete service, saving you the time, frustration and hidden costs of dealing with a series of subcontractors.

High Pressure Die Casting provides the shortest route from molten metal to completed component. By injecting molten metal (whether it be aluminium die casting or zinc die casting) into a hardened tool steel mould and allowing it to solidify under pressure before ejection. 

This process allows fast, precise, cost effective production of aluminium or zinc die castings, meeting the needs of hi-tech industries where product appearance and dimensional tolerances are critical but volumes are not always large.

MRT have high pressure die casting machines with locking forces of between 220 and 530 tonnes. All have microprocessor control and the latest include computerised real-time shot control, automatic ladling and die-spray, and automatic casting extraction and cooling.

Small Quantities? - No Problem!
Many pressure die casting foundries only offer their services for high volume orders, claiming that lengthy set-ups make the process prohibitive to small quantities of zinc or aluminium.

MRT have optimised their tooling preparation and set-up operations to make the process more accessible to customers who require only small quantities of aluminium or zinc castings, but whose applications would benefit from the excellent dimensional and cosmetic properties of pressure die casting.

So, MRT can provide the complete service, whether you require a batch of 10 or 10,000.

MRT have a range of microprocessor controlled hydraulic gravity die casting machines, which mechanise movements of the die, increasing production rates, and improving consistency. The machines offer tilt pouring, and hydraulic movement on up to four axes. MRT also have facilities for producing sand cores to cast complex internal shapes.

Heat Treatment
MRT supplies castings to all standard heat treatment specifications.

Non-Destructive Testing.
For critical components, MRT can provide X-ray, dye penetrant and pressure testing.
 

Sand casting offers the simplest medium for production of non ferrous castings, by pouring molten zinc, aluminium or copper into a sand mould. 

When is Sand Casting used? 

The sand casting process is chosen for the production of:

• small numbers of castings
• a complex shaped casting requiring intricate cores
• a large non ferrous casting

• low tooling costs
• largest casting sizes achievable
• very low gas porosity is possible
• general versatility of the process is good 

• low casting rate
• 3-5mm minimum wall thickness
• poor linear tolerance (e.g. 4mm/m)
• rough surface finish
• coarser grain size than gravity die casting

MRT's extensive modern CNC Machining facilities are at the very core of the Company's operations.  In a market where customers require the shortest possible lead times, the benefits of finding a single source who can cast, machine and finish components can slash lead times and greatly reduce the logistic and management costs of dealing with several subcontractors. Most critical to your competitiveness, however, is that the machine shop which you choose to rely on has the best kit and skilled staff to optimise the quality and productivity of their processes.  MRT is that machine shop.

At MRT, our experienced team are specialists in CNC Machining Castings and understand the casting process itself, so they know the important inspection aspects of working on cast components. In terms of machine tools, we have some of the fastest and most versatile machines available.  Our ongoing investment programme ensures that the latest technology is employed to minimise production costs and enhance product quality.

We appreciate that our customers are all specialists in their fields. They need a reliable supply of quality components, on schedule and ready for production. So, to eliminate your customer's frustrations and hidden costs of dealing with several subcontractors, MRT offers a complete package, leaving you free to concentrate on your application of the component.

To complement the extensive services of our foundry and machining divisions, MRT supplies a wide range of metal surface finishing processes, including:

• Alochroming
• Anodising
• Assembly
• Ball Burnishing
• Chromating
• Degreasing
• Electroplating
• Impregnation
• Painting
• Phosphating
• Polishing
• Powder Coating
• Silk Screen Printing
• Shotblasting
• Vibratory Finishing

MRT are experts in managing the supply chain of components through the various stages of production. Bespoke computerised scheduling software manages the entire process, providing traceability for every batch and ensuring that we stick to our delivery promises.

When problems do occur and customer requirements change, MRT's small, friendly team are always ready to respond. In everything we do, MRT delivers the high level of service you would expect from a family business which has been successful for over 50 years.
