If you are interested in acrylic molding let s first examine what acrylic material is. Acrylic molding acrylic is one of the clear plastic molding materials the rebling team is experienced at. Rebling has plastic injection molded acrylic for a variety of applications including lighting equipment housewares and medical devices. It is ideal for producing high volumes of the same object.

An injection molding machine consists of four major components. Mma acrylic sheets and pmma resins. By contrast thermoset plastics can only be heated once typically during the injection molding process. Injection molding is the most common modern method of manufacturing acrylic parts.

Because designing and creating the tool requires more time and heavy duty expensive materials the initial lead time and tooling cost is greater than thermoforming however tooling is a one time cost so for large quantities and repeat orders acrylic injection molding can provide a low per unit cost. The only major variable that can affect the forming process is the thickness of the plastic sheet. For thicker sheets it will take longer and for thinner sheets it will take less time. Injection molding equipment.

Acrylic is heated to a liquid then injected into a custom mold with a high pressure injection tool. This article uses a sheet about 1 4 thick so all times are about 10 to 15 minutes per step.
