Tooling for Resin Transfer Molding

MRM’s custom tooling assures the accuracy of your design and parts.  In fact, our track record shows 100% customer acceptance of all tooling manufactured at MRM.  Save new part and tooling costs by avoiding retooling molds made elsewhere to increase part aesthetics and manufacturing efficiencies.

frp reinforced,composite frp, thermo plastic composites The exact tooling you will need to have your RTM components produced depends on a number of variables. When you discuss your project with us, we will be able to provide the best tooling solution for the job. Some of these variables include: the application of your part(s) and other details, how many parts you need produced, how often the design might be changed, what size and thickness your parts will be, etc.

One of our staff will be glad to explain your options to you so you can make informed decisions about the best tooling. In comparison to compression molding, RTM tooling offers shorter lead-times and lower costs to develop. This means your production run is ready faster with less tooling costs.

Since RTM composite manufacturing is a "closed mold" process, the tooling we use to produce parts for you will involve creating these custom molds. A male and female matched die (molds) set are constructed in most cases using vinyl ester epoxy composite resins with the appropriate reinforced fiber materials. Other RTM mold constructions may use epoxy, aluminum and/or steel combinations. We also have more details on the Resin Transfer Molding process because the fiber and resin options, along with other fillers that can be used, each meet different needs for the thermoset molding components being produced. We will advise you of the best solution for these too, and match your tooling needs accordingly.

We can work with your designs, such as: CAD, DXF, IGES, Solidworks, or Autocad. Upon completion of your tooling project, molds are maintained in controlled conditions to assure your production part quality.

Although not officially part of the tooling, there is another aspect of producing FRP fiberglass and glass reinforced plastics components that you should be aware of. We can precision trim your components after molding with part specific factors such as holes, slots and other cut-out areas.

Please be sure to contact us for any questions or RTM tooling needs.
