Tooling Expertise

To ensure full project management and control, flexibility and efficiency, Martin’s Rubber has maintained a dedicated in-house tooling department since the 1940’s, ready to design and produce high quality, accurate tooling. Martin’s Rubber is therefore able to offer a rapid turnaround for rubber mouldings and polyurethane foam products, thanks to this dedicated in-house tool room. This facility also allows for the production of Engineered Plastic products, whether standard or bespoke. These days, our highly skilled staff use leading edge software packages Solidworks for CAD, and Hypermill for CAM, to either draw new files in 3D or import customer supplied product files in 2D or 3D, prior to designing the appropriate tool to produce the required part. Most current file formats can be accepted, and files provided for customer approval prior to creating a mould tool to produce the actual part. If required, a rapid prototyped part can be supplied from these files for final approval, or rapid machining used to provide a pre-production part, depending on the product and specific material required. Our in-house tooling facilities allow us to remain fully flexible with our customers lead times and we can often meet emergency deadlines when required; our capability includes 5 axis CNC machining, Spark Erosion and Surface Grinding, as well as the more traditional manual turning, milling welding and fitting skills.

The design of a tool will be dependant on a number of factors, including:

  • The precision or tolerances required
  • Any critical features
  • Any cosmetic or A face requirements
  • The dimensions and orientation of the part
  • Whether any inserts are required
  • The particular material properties and shrinkage characteristics
  •  The particular Moulding Press characteristics
  • The quantities and production rates required

Product design is best discussed with us at an early stage to ensure that all requirements are met in terms of production efficiency and aesthetic result of the finished part. It is always a problem trying to compensate late in the design stage for deficiencies in other parts already committed. Tooling design considerations to assist in economical production are vital at the design stage, as it is often the case that parts or tools are far more expensive than they otherwise would be, due to the inclusion of features that are functionally redundant but add significantly to the complexity of the tooling. This is an increasingly common issue in this age of CAD; “if I can draw it why can’t you make it?” is often the cry……………to which the answer is usually “well, we can, just”, followed by the customer saying “how much?!” Our in-house facilities mean that we can modify tooling for development parts very rapidly, and maintain existing production tooling promptly such that the quality of parts manufactured is consistently high. Coupled with our design, prototype and development service, Martin’s Technical staff are able to confidently offer a full and expert service, from conception through to final production.
