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. 6.Excellent aftersales service

   Technological Process: Blanking→Rough Machining→Quenching & Tempering →Semi Finishing Machining→Finished Product→Detecting→Nitring/Alloy Processed →Finish Machining   Advantages of Extrusion machine parts screw barrel for plastic machinery processing : Advanced nitriding technology Duplex alloy spraying technology High corrosion&abrasion resistance to prolong lifetime of screw and barrel We use special alloy powders being sprayed and welded on the screw's ridge/flight,and use different alloy and welding methods for the screw of different functions. For good plasticizing , it has many designs to meet customers' demand . Such as granual type , mutant type , wave type , barrier type , double screen typr ,shunt type , separation type , exhaust type and so on . We can design for you with high cost-effective .  Remarks : We are able to take mapping, design for clients and make products as per customer's drawing or sample excellently , also can help customer to repair the old screw and barrel by using bimetallic-alloy process . Screw structure, compression ratio and material can be changed according to different product and output . Technological Process can be chose according to your requirments . Commonly used materials:38crMoAIA , nitriding treatment . Various high quality alloy steels , according to different usage , the choose for alloy is different , some require for abrasion-resistant while some require for corrosion resistant. For standard , we have Fe-based , Ni-based , W2C alloy , tungsten alloy etc for choice.               About O.S.D : Our Strength: We have an experience of more than 20 year of manufacturing and designing Plastic machines, varied Screws and Barrels and spares.  We concentrate on improving quality, updating design and enhancing service.
