Extruder Degassing (Drying)

Extruder degassing is an integral process in plastic manufacturing. It involves eliminating unwanted gases, moisture and other volatile components from molten polymers before they're shaped or molded.

Vacuum technology plays a pivotal role in extruder processes by creating a controlled environment where trapped gases can be efficiently removed from the molten material. This leads to an enhanced product quality and consistency by a reduction of defects.

Vacuum forming is a versatile manufacturing method used across various industries to shape heated plastic sheets over molds. It's employed for producing various items, including packaging, automotive components, bathtubs, prototypes and many more.

Vacuum forming is a rough-vacuum application which uses the “power of vacuum”. The process is less demanding for the vacuum pumps as there is only little outgassing. This process ensures uniform distribution of material, resulting in precise and consistent finished products.

Vacuum Transport

Vacuum transport systems are essential for material handling in industries like e.g., printing or packaging. These systems utilize vacuum technology to move items, such as paper sheets or products, efficiently along a conveyor belt or production line.

Vacuum pumps create a low-pressure zone, securely holding and transporting materials without mechanical clamps or grips. This approach minimizes damage and ensures smooth and efficient transportation. The vacuum pumps can also create the needed air flow for the transport of flakes or pellets.

Solid State Polycondensation (SSP) is a crucial process in the production of high-performance polymers. It involves the removal of residual monomers and other impurities from the polymer matrix.

Vacuum technology is employed in SSP to create a controlled, low-pressure environment that aids in the removal of contaminations, ensuring the final polymer product meets stringent quality standards.

Plastic Recycling

Plastic recycling is essential for reducing environmental impact and conserving resources.

Vacuum is used in plastic recycling to dry and clean the molten plastic flow inside the extruder. Contaminants such as moisture, residues of glue, diluted gases and others can be removed.
