The injection molding process is the most popular technique for manufacturing plastic parts. This is due to the enormous variety of ways in which this material can be molded, as well as being a fast and efficient process.
The principle is very simple, in a machine plastic material is melted, which is injected into a mold that gives the desired shape .

Injection molding is one of the most important shaping processes in plastics processing. Through this process it is possible to produce components in large quantities and with high freedom of configuration in a cost-effective manner. Internal threads, undercuts, gear teeth or free-form surfaces are also possible.
A rotating screw melts the plastic granulate under the action of temperature and carries the plasticized mass towards the screw tip. Finally, the melt is injected thanks to an axial displacement of the high-pressure screw in the closed mold where there is a hollow space (cavity) with the shape of the desired component. After a cooling or hardening phase, the mold opens and the finished parts can be ejected or removed.
