Vacuum pumps are widely applied in processing plastics, mainly to extract gases and vapour and to operate at lower processing temperatures to manufacture high quality products. Our expertise in vacuum applications allow us to design robust and reliable vacuum systems to meet your vacuum needs.
Vacuum pumps play an important role in degassing plastics as water vapour, toxic and corrosive gases and other impurities affect the quality of the product.
Polymer melts are degassed to remove these impurities at low pressures using vacuum pumps on extruders when being compounded into different grades with additives and colourants and while being formed.
Various plastics manufacturing methods like vacuum forming, injection moulding, EPS foaming, etc. employ vacuum pumps on the mould to avoid significant defects such as burn marks, incomplete filling of the mould cavity, moisture removal to eliminate internal defects and to create that all important smooth surface finish.
Our experts will help you make the right selection from the wide range of Edwards vacuum pumps, for your plastics degassing, processing and recycling application.
