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, diameter 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 diagnostics and software updates.
Upgrades as you grow
Additional die heads, calibrators, co-extruders and winders can be added later, so the line grows with the duct sizes and bundle types you sell.
Need help selecting a line?
Send us the duct size or bundle type, the raw material, the target line speed and the country of installation. Our engineers will recommend the extruder, die head and downstream configuration.
