RAL 5021 · semi-matt finish
Production line introduction
How the Single Screw Plastic Pelletizing Line is engineered, and which sub-assemblies protect the properties your customers actually buy.
A single screw pelletizing line for PE, PP and PS regrind with water ring or strand cutting, supplied standalone or as the pelletizing stage of a washing line.
Every BENK line is matched to the material and product you actually sell. The extruder, die, calibration or forming section and the downstream automation are sized together, then assembled and trial run in our Zhangjiagang works before shipment, so the performance you see in the factory acceptance test is the performance you install. The machine frame is finished in RAL 5021 water blue with a semi-matt powder coating.

Why buy from BENK Machinery
Extrusion specialists, not traders
BENK designs and builds extrusion lines in Zhangjiagang with an in-house R&D and process team, so machine selection is matched to your resin and product instead of a catalogue number.
Evidence before shipment
Every line is assembled and run in our works. You receive trial video, gauge and output records, and are welcome to attend the factory acceptance test.
Total cost, not lowest price
Energy-efficient drives, permanent magnet motors and optimized heating reduce kWh per tonne, which usually matters more over five years than the initial purchase price.
Real commissioning support
Our engineers install, commission, train your operators and stay involved until the line hits the specified output and quality on your material.
Spares and response
Critical spares are stocked for fast dispatch, and the Siemens Ethernet control platform allows remote diagnosis before a service visit is needed.
Upgrades as you grow
Co-extrusion, gauge control, automation and downstream equipment can be added later, protecting your original investment.
