the process

Thermoset Castable Polyurethanes are a blend of a resin and a curative that yield high performance engineering properties that are not obtained by any other process.

Resin and a curative are blended to form a chemical cross linking. Once this reaction takes place, the mix has to be poured into a heated mold cavity before it cures. The product is demolded and then cured in a hot oven for at least 16 hours. Once it is cured it cannot be re-melted or re-ground and re-used.

The main advantages of this molding process is the ability to mold large or complex shaped parts with fairly in-expensive molds, and the ability to obtain a variety of physical properties and combination of properties that can be optimized for a given application.

the concept

It begins with your idea, or concept, of a part. This idea may be as simple as a verbal description of a new part or as detailed as an existing part with previously established specifications. We meet and discuss these requirements and your expectations of the part to be produced. A quotation for tooling and part pricing will be given after this discussion.

tooling and design

Once the quotation has been accepted, tooling will be designed by our team of experts. Tooling will be machined from aluminum, steel, or other alloy depending on the requirements of the mold. The new mold will be checked by our team before a sample part is poured to confirm its match to design specifications. During this time we will also create finished part drawings and other inspection routines, so that initial parts can be inspected during the rest of the process.

pouring a part

The mold will then move into one of our urethane workstations and a sample part will be poured. Our technicians will use previously established formulations that will yield a part that will conform to your design requirements.

inspection and approval

These first parts will be compared to standards established during the initial stages of the process. Once we confirm these standards have been met, the part will be sent to you for your approval. Production begins only after you confirm the initial part meets your requirements.
