Doppelschneckenextruder

What is the biggest concern when buying an extruder double screw? It’s the fear of incorrect drawings, mismatched dimensions, or discovering upon arrival that the shaft head spline cannot fit into the gearbox. At our company, these worries are all unnecessary. Our 18 years of experience has built a database that reduces the probability of dimensional errors to zero. With just one phone call, we can replicate an identical component sequence

Plastic Extruder Screw

In a twin-screw extruder, the screw structure is divided into: screw shaft + screw element + screw head.

The modular screw rod, where each element plays its own role independently.

Customization Process For Screw

  1. Provide material specifications or material requirements
  2. Provide drawings or samples
  3. Review drawings or samples, and discuss parameter details
  4. Provide a quotation and production cycle
  5. Make payment and arrange production
  6. Inspection, packaging, and shipment

 

Can customize the screws to your desired specifications, including those from well-known industry brands, and can start with a sample.

Whether it’s recycling, high glass fiber, or high-filled calcium powder, our screws are all competent and can work for long periods in high-temperature environments. Leave the complex manufacturing process to us, and we will deliver “cost-effectiveness”.
