Injection Molding

Injection molding is a manufacturing process for producing parts by injecting molten material into a mold cavity. It is the most common method for mass-producing plastic parts, offering excellent repeatability, low per-unit cost at scale, and the ability to create complex geometries. The process involves heating plastic pellets until molten, injecting them under high pressure into a precision-machined mold, cooling the part, and ejecting it. Key considerations include gate design, wall thickness uniformity, draft angles, and material shrinkage rates. OrderCAD offers both prototype tooling (aluminum molds for low volumes) and production tooling (hardened steel molds for high volumes). We work with over 50 thermoplastic and thermoset materials, and our DFM analysis ensures your parts are optimized for the injection molding process.
