Multi Co-Extrusion Profile Extrusion Line
Profile Extruder, Plastic Profile Extrusion Machinery, Profile Co-Extrusion Line
Basing on market and clients’ demands, Zeqi has developed the multi co-extrusion profile extrusion line basing on our original co-extrusion equipment. This line adopts special screws, and co-extrusion technique to realize better plasticizing and sealing result. We can customize different models of and auxiliary equipment according to different raw materials and applications. The plastic profiles produced by this extrusion line, such as bathroom accessories and automotive rubber seal strips are widely applied in automotive and decoration industries.

Zeqi introduced the advanced technique from Germany to produce screws. Equipped with different precise molds and different auxiliary lines, the high-performance single screw extruder or multiple co-extrusion devices are able to produce diversified automobile sealing strips of different textures (hard/soft) from different materials such as PVC/SPVC, and TPE (TPV, TPO, TPU). They can basically meet the production needs of auto decorative sealing strips. By replacing the screw barrel, we can apply the extrusion line to process sealing strips for common machineries. This PVC profile extrusion line is used extensively, particularly for making TPV sealing parts, which have gradually witnessed a tendency to be a replacement for rubber sealing parts. Considering the forming effect control and production speed of the extrusion line, Zeqi has been a leading manufacturer in Chinese extrusion industry.
Main performance of TPV dynamically vulcanized thermoplastic EPDM elastomer/ rubber:
TPV is easy to be welded and can be recycled, environmentally friendly and nontoxic.
Main characteristics of TPV dynamically vulcanized thermoplastic EPDM elastomer/ rubber:
