OSD ADVANTAGES	1.Advanced Nitriding Technology 2.Duplex metal Spraying Technology for high corrosion and abrasion resistance 3.We use special alloy powder being sprayed and welded on the screw's ridge, and use different alloy and welding methods for the screw of different functions. 4.Fast and on time delivery . 5.Longer lifetime for the screw barrel.

Technological Process:

Blanking→Rough Machining→Quenching & Tempering →Semi Finishing Machining→Finished Product→Detecting→Nitring/Alloy Processed →Finish Machining

For good plasticizing effect, we have different design of screw barrel to meet customer's demand:

gradual type, mutant type, wave type, barrier type, double screen type, shunt type, separation type, exhaust type, pin type, double-head type, multi head type etc.

Single extruder screw barrel for film blowing extruder machine
have following features :

• The screw adopt barrier type mixing zone.
• The barrel feeding zone is groove feed bush and made of hard alloy.
• It results in higher output rates, homogeneous plasticizing and less material slippage.
• Bi-metallic screw&barrel can be provided for two-three times more lifespan than nitrided screw&barrel.

Features:

• Easy operation
• Optimum performance
• Durable
• Low power consumption
• Corrosion resistance
