Vacuum Solutions for Plastic Industry - Brochure
Plastic processes made efficient with Edwards vacuum solutions
Vacuum pumps are widely applied in processing plastics and composite manufacturing, mainly to extract gases and vapours and to operate at lower processing temperatures. Production of high-quality everyday thermoplastics with lower environmental impact has become a necessity.
Edwards vacuum systems can play a significant role in helping you to drive up your product quality and throughput with new levels of reliability, flexibility and profitability. Our vacuum pumps have been successfully supporting the plastics circular economy at every step of plastics lifecycle.

- Steady pumping for batch and continuous processes
- Efficient handling of entrained gases
- Standard and customised vacuum systems
- Applications expertise for selection of vacuum technology for your polymer and process
Processing plastics with reliable vacuum
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 colorants and while being formed.
When high quality plastics are manufactured, vacuum pumps become one of the key tooling components on the extruder especially employed during processes like:
- Polymer production
- Compounding and masterbatch
- Plastics extruder degassing
- Film and sheet production
- Vacuum calibration
- Vacuum forming
- Fluorination of plastics
- EPS foaming and moulding
- Pneumatic conveying of additives, fillers, pellets
- Central vacuum
Recycling plastics to a higher purity with vacuum
Various plastic recycling methods make use of vacuum systems to remove entrained gases and aid the reaction in solid state recycling of PET, HDPE, LDPE, PC, ABS and even in liquid state recycling process for PET. With the advances in plastics recycling methods, our vacuum pumps have proven to be a critical piece of equipment for recycling plastics to a higher purity standard.
- Extruder degassing for Mechanical recycling
- Solid state and Liquid state chemical recycling
- Pneumatic conveying for physical recycling
Enhance your Composites production with vacuum
Composites are made by combining two materials having different properties, a reinforcement (fiberglass, carbon fibre, aramid fibre) with a resin matrix which is another name for polymer. With this combination, you get the best of both worlds, strength from the fibre and the unique benefits from polymer (corrosion resistant, heat resistant, lightweight).
Composites can be manufactured using various open or closed methods depending on attributes, shape of the end product, production volume and usually with the aid of vacuum pumps.
- Vacuum Bagging
- Vacuum Infusion
- Vacuum Assisted Resin Transfer Moulding (VARTM)
- Vacuum Compression Moulding Vacuum Assisted Pultrusion
Our expertise in vacuum applications allow us to design and deliver robust and reliable vacuum systems to meet your vacuum needs in plastics and composites manufacturing processes.
