Molding/CNC Machining/3D Printing
Plastics are formed into their final shape during the molding process. Several molding processes are used in plastic production, including rotational molding, blow molding, extrusion, and injection molding. The choice of molding technology is influenced by the type of plastic, the complexity of the part, and the production volume. For example, extrusion is best used to create long, continuous shapes, while injection molding is suitable for mass production of complex parts.

CNC machining
CNC machining is a process that creates a desired object by removing material from a solid block using a computer-controlled, fast-rotating tool. This subtractive process is ideal for prototypes and precision parts across different industries as it offers a high level of accuracy and is suitable for a variety of polymers such as drelin, nylon, acrylic, and polyetheretherketone (PEEK)
