This technique is often called compression molding. This mold has screws on both sides which you can tighten or lose before and after adding the molten material into it. Keep the gates of the mold large for easy transfer of the mold material

We at Go4mould equip our mold with the cooling operation. The molten polymer is set to cool until it gets into the solid-state. Do not open the mold before the due time or otherwise you’ll not get the desired product and finishing. Polymer Injection moulding is a profitable technique because it gives accurate results and can be used for the heavy production of plastic injection molds.
