We compression mold HDF (High-Density Fiberboard), wood fiber, fiberglass, aerogel, PET, and composite materials using thermal forming process. This process uses heat and pressure to mold parts into a 3 dimensional shape. Compression molding requires matched-metal tooling which are usually hardened steel.

Compression molded parts are commonly used in automative applications for seat backs, door trim panels, load floors and heat shields. The contoured shapes molded into parts add rigidity and integrity. These types of components are structural in nature and are natural sound deadeners.

Wood fiber, HDF, and MDF are all sustainable products.

The Process for Compression Molding

Matched metal tooling used for compression molding can also incorporate a trimmed edge. This  essentially acts as by-pass shear during the compression phase of the operation. This results in a clean trimmed edge around the perimeter and holes and cutouts.

Molding and trimming in one operation is more efficient reducing the number of processes involved with production.

We have over 30 years of experience in compression molding project management and tooling development. U.S. Trim can manage your entire program from development, prototype, to finished product.

If you have a project that requires 3-dimensional parts, give us a call. We’ll take a look at the design and recommend the best material and process for your specific application.
