Plastic injection molding, or commonly referred to as injection molding, is a manufacturing process used in the mass fabrication of plastic parts. It involves an injection of molten plastic material into the mold where it cools and...
Polyurethane molding is the process of fabricating or manufacturing plastic parts by introducing a urethane polymer system into a tool or mold and allowing it to cure. Like any other type of plastic, the excellent processability...
Rotational molding, commonly referred to as "rotomolding", is a plastic casting technique used to produce hollow, seamless, and double-walled parts. It uses a hollow mold tool wherein the thermoplastic powdered resin is heated while being rotated and cooled to solidify...
Thermoforming is the process of heating thin plastic sheets to its forming temperature and stretching it over a mold which takes its shape. After cooling and setting of the molded plastic sheet, each part will be separated from its batch to form a single unit or product...
Blow molding is a type of plastic forming process for creating hollow plastic products made from thermoplastic materials. The process involves heating and inflating a plastic tube known as a parison or preform. The parison is placed between two dies that contain the desired shape of the product...
Fiberglass molding is a method for forming complex and intricate parts using fiberglass resin. Though there are several reasons for producing parts and components from fiberglass, the most pressing reasons are the...
Plastic coating is the application of liquid polymers or plastic onto the surface of a workpiece through dipping/immersion. The result is a thick plastic finish for protective and decorative purposes. This gives the material additional...
Closed cell foam is a type of foam where the “cells” are tightly pressed together and enclosed. It contrasts open cell foam, such as polyurethane, with interconnected open cells. With closed-cell foam, because none of the cells...
Plastic fabrication is the process of designing, manufacturing, and assembling a product made out of plastic material or composites that contain plastic. There are numerous plastic fabrication methods known today, considering the...
