You understand how your product should function and what it should look like – but unless it can be manufactured economically, consistently and reliably, it will never reach its full commercial potential.
Before committing to production tooling you need expert advice to help you confirm whether casting is the right production method, and if so which casting process is most appropriate. That selection will help to define the component design, and to build a realistic, strong commercial foundation for your product. That means involving the right expertise at exactly the right time.
At MRT Castings, we encourage customers to bring us in at the earliest concept stage. This is where Design for Manufacture (DFM) delivers the greatest value.
When designing a cast component, the first steps of the project are vital to smoothing the future path. For a modest, structured fee, we guide you through each stage of development:
· helping you to select the right manufacturing process
· enhancing your design for casting
· ensuring repeatability and consistent quality from the outset
· building a realistic commercial business case for the project.
Designing cast components is a specialist discipline. Draft angles, wall thickness, material flow and the avoidance of heavy sections or undercuts must all be addressed early. With decades of experience, MRT brings the knowledge needed to get this right first time – reducing downstream costs in tooling, machining and assembly.
As you work with us, you will quickly see the value of having an expert that is transparent and direct. Your commercial success is our priority, and with that in mind, we’ll challenge where needed and guide you where it matters most.
Follow a single component, a die-cast square housing, through all seven stages of MRT's Design for Manufacture process. Click a stage to jump straight to it, or use Next / Previous to step through in order.
We prefer to get involved early, ideally at the concept stage, before the design is fully defined. Whether you come to us with a finished CAD model or a sketch on paper, we're happy to sign an NDA and get into the detail with you.
We review your design for manufacturability, checking whether the casting process is the right fit for the part and its design intent. Using CAD and our design expertise, we assess geometry, wall thicknesses, draft angles and potential problem areas before a single gram of metal is poured.
MAGMASOFT is the foundry industry's most powerful casting simulation software. We use it to validate and refine your design before tooling begins, running multiple simulations to identify areas of risk, including porosity, air entrapment and flow issues.
We work closely with our trusted toolmaking partners, involving them at the design stage to ensure tooling concepts are practical, efficient and aligned with real manufacturing conditions.
By this stage, we can define the complete manufacturing process, tolerances, machining strategy, finishing requirements and logistics, and build a transparent cost model around it, stable for as long as the design parameters are maintained.
Before production begins, we make sure everything is in place for a smooth transition, from final design sign-off to process documentation, quality parameters and supply chain readiness.
Our relationship doesn't end when production begins. We support you through the production lifecycle by monitoring quality, supporting continuous improvement and staying close to your team as your product evolves.
Your success is our success. Let's build it together, however early in the process you are, we're ready to help.

Designing castings is a specialist skill. Die cast components require specific features such as draft taper, even wall thicknesses, and the avoidance of undercuts and isolated heavy sections. All of these issues can be easily overcome if you work directly with our team before you freeze your design. Costs of machining, surface finishing and assembly can also be dramatically reduced if we are consulted early in the design process.
MRT have been manufacturing high quality components for over 75 years. It's the experience, techniques and tricks of the trade that we have developed over that time that we will share with your designers and engineers to optimise your products.
MRT specialise in complex components for demanding applications. Consistent and repeatable components require advanced process control and meticulous design. We will explain the features needed to ensure excellent finish and dimensional accuracy.
MRT operate SOLIDWORKS and FUSION with POWERSHAPE as our CAD packages, alongside MAGMASOFT, the foundry industry's most powerful and respected casting simulation software. We have resources for producing prototypes for evaluation and testing prior to committing to production tooling.
Where required, MRT can prepare full component drawings, solid models, manufacturing and finishing specifications.
