Injection molding (IM) is a versatile process used to shape thermoplastic materials to obtain final molded products (generally with thick sides and/or to achieve complex shapes).

This type of mold allows to produce in great quantity and to reproduce extremely precise dimensions.

The process follows three stages:

  1. The liquefaction of resin granules using a screw and machine barrel heated through high pressure.
  2. The injection of an average quantity of melted material using a runner system inside the mold. The liquefied material placed on the cold sides of the mold then becomes hard thus giving it shape.
  3. The finished product is then taken out when sufficiently cold so as to obtain the final form wanted
