Considering the customers’ needs and specifications, the best way to mold a part is to make compression molds from either epoxy laminate or aluminum, creating the best tilt and parting line for the process.
Have experience with making tooling to process vinyl, “PVC,” high-density polyethylene, “HDPE,” and polypropylene, PP. Aluminum tooling will have cooling lines plumbed to a manifold, vacuum holes drilled, a back plate, and a vacuum connection.
Vacuum molds can also have a texture placed on the surface to the customer’s specifications. The customer would supply a texture master, and then we would use this to develop the textured surface on the mold.
