Plastic Extruder Conic Twin Screw And Barrel / Bi-metal Screw And Barrel For Double Twin Screw Extruders

1.Series of conic twin screw and barrel

2.HYPET Special features

1). Hard chrome plating for the twin screws, especially at the metering section of the screws, which will make the screws more anti-corrosion, more anti-wear especially the feeding mix raw material including some acids or other corrosive substances.

2).The bimetallic barrel is centrifugally cast a 2-4mm thick alloy coat on the output section of barrel inner wall which has excellent corrosion resistance, abrasion resistance and high working temperature. And its useful service life is greatly improved contrast to the common nitrided barrel. Bimetal has more obvious advantages when processing high calcium carbonate powder PVC mixture to enhance the abrasion life.

Another bimetallic barrel is machining the grooves at output section of the barrel then spraying the alloy powder on the groove. The length is about 400-500mm.

3) High output with less energy cost reached by better designing for different raw material, formulation, products and processing equipment etc.

4)The compression ratio of the screw can be designed according to different raw material and products. Different design for barrel to meet with customer’s requirement on high cost performance for option.

A Barrel		Integrated structure, warranty 18 months
		Material 38CrMnAlA+ grooved Sprayed alloy
		Suitabe for less filler and short working life
B Barrel		Two parts structure, warranty 36 months
		Material 38CrMnAlA+ Small part in special alloy
		Suitabe for more filler or longer working life
C Barrel		Small feeding zone + longer barrel part double life
		Material 38CrMnAlA+ longer part in special alloy.
		Suitabe for more than 200 phr filler
Screw		Material 38CrMnAlA+ grooved Sprayed alloy
		HYPET designed and making with advantage following
		High quality/high filler/high output for PVC pipe
		PVC-WPC/PE/PP/WPC/building profile
		Foamed board/sheet/hard or soft PVC pelletizing.

       Located in Shenzhen City which is the most lively and youngest top city in China, it's next to HongKong and Guangzhou City. 

       Shenzhen HYPET founded in 2002, and it inherits from China national extrusion machinery entrerprise. Base on Germany and Italian technology, HYPET invented and manufacture unique gear box with own patent. For these reason to keep HYPET tech and machine quality priority in extrusion machine field. 

      The first block type DIY plastic extruder solves the machine agents' many problem. They can easily get extruder parts from HYPET factory then assembles them in their own workshop via the installation video. 

      The plastic extrusion line core part is the extruder. If the extruder is good, then the line 70% is good. So HYPET offer the service to match local downstream or old downstream service.

       Shenzhen HYPET machine is focus on top quality but best enconomic price. Our main plastic extrusion machine includes but not limited PVC / HDPE / PPR pipes extrusion production line, PVC and WPC all type of profiles (PVC window, ceiling, wallpanel, decking, gutter, duct...) production line, PVC plastic marble sheet line, SPC floor production line, WPC door plant, PVC foam board line, Nonweave melt blown fabric line.....

       HYPET also offer the special PVC processing aid to decrease your final product cost and increase the product quaity & better shining surface.

      We have a full technical team can help you design, manufacture, assemble, inspect and test the plastic machine meet your request.
