The outline of injection molding - Polyplastics

Injection molding machine is divided into 2 units i.e. a clamping unit and an injection unit. The functions of the clamping unit are opening and closing a die, and the ejection of products. There are 2 types of clamping methods, namely the toggle type shown in the figure below and the straight-hydraulic type in which a mold

Guide to Manufacturing Processes for Plastics

Rotational molding requires less expensive tooling than other molding techniques as the process uses centrifugal force, not pressure, to fill the mold. The molds can be fabricated, CNC machined, cast, or formed from epoxy or aluminum at a lower cost and much faster than tooling for other molding processes, especially for large parts.
