DH Mold supply extruded plastic tubes, pipes, rods, channels, profiles, and spiral wrap by Materials such as polystyrene, nylon, polypropylene and polythene can be used in a process called extrusion. These are thermoplastics and when they are heated and then pressured in a mould they can be formed into different shapes and sections.

Plastic extrusion is a manufacturing process through which plastic is melted, shaped into a continuous profile, and cut to length. This process is used in the production of a wide variety of items, including piping, wire insulation, and plastic sheeting. Even adhesive tape and window frames include extrusion as part of their manufacturing processes.

In this process, raw plastic is fed into a heated extruder cavity or cylinder. Typically, the raw plastic is in bead form and may be mixed with colorants before the extrusion process begins, and in some methods, ultraviolet (UV) inhibitors may be added to the raw plastic beads as well. Once inside the machine, the plastic beads and any accompanying material move through an opening in the extruder cavity towards a screw mechanism. The screw rotates, forcing the plastic material to advance through the cavity.

We specialize in big volume runs but also have a long history of smaller custom runs. Whatever the size, DH offers you competitive pricing, proactive service, and quality you can count on.
