We are offering Injection Molding Screw Barrel with Bimetallic Layer. Screw and barrel is the most important part of the injection molding machine (Vertical and Horizontal). With the perfect design, our injection molding screw barrel is able to realize the high plasticizing capacity and molding function of your machine. A full range of base material and surface coating are offered for your specific processing applications depending on wear resistance, corrosion resistance and material strength.Base Material: 38CrMoAlA, 40Cr, 42CrMo, SKD-61, Stainless Steel, etc.Surface Coating: Nitriding, Bimetallic, Hard Chrome Plated, Quenching, ect. Specification:Clamping force: 25t-3200tInjection volume: 30g-2500gTechnical Data:Nitriding thickness: 0.50.8mmNitriding hardness: 900HVSurface roughness: Rao0.4/mSurface Straightness:0.015mm/m All types of custom design screw and barrel components, to meet different customer requirements.Since the injection molding screw tip is always under the higher wear and corrosion working condition than screw body. Per customers request, we will also provide the screw tip with different material from screw body, like SKD61 or bimetallic (alloy) coating.

We offer single screw barrel for extruderthe single screw barrel is widely used on the plastic extruder, rubber extrusion and food extruding machine. We will manufacture any specification from 15mm to 350mm, with the maximum length of 8000mm for the feed screw and its corresponding barrel. a full range of base material and surface coating are offered for your specific processing applications depending on wear resistance, corrosion resistance and material strength. Base material: 38crmoala, 40cr, 42crmo, skd-61, stainless steel, etc. Surface coating: nitriding, bimetallic, hard chrome plated, quenching, etc. technical data:nitriding thickness: 0.50.8mmnitriding hardness: >900hvsurface roughness: rao0.4/msurface straightness:0.015mm/m
