We can supply a complete range of injection screws. Based on our large experience we can recommend the proper type of steel and surface treatment to minimize wear. According to customer’s needs we can propose nitriding steel, stainless steel, tool steel and also sintered steels (CPM/PM).
We deliver screws according to OEM’s specification.A screw is the heart of the process and determines the the productivity and the quality of the molded parts. For this reason we can deliver screws with a Maxi Melt design that can help you to optimize your production.
Our screws can be delivered with all kind of treatments to improve surface conditions and to improve plasticizing. A beter surface finish will improve plasticizing and reduce reject rate. All these improvements are just standard for us, so that we can bind the fulfillment of these objectives to the purchase of the screw.
Up to date machinery and CAD CAM facilities make it possible to manufacture high quality complex products with tight tolerances from different kind of materials to be selected from case to case with a high surface finish suitable to withstand wear and or corrosion conditions.
Choosing the right screw material is important to have the right plasticizing performance in order to reduce wear and corrosion problems.
For larger screw sizes we often use nitrided materials with the flighttips welded welded with different materials options. This done to create wear/corrosion protecting or improve friction/lubrication.
In most cases these coatings are used to reduce friction, and therefore improve the plasticizing, or protect against corrosion.
We have five different alloy solutions listed in the tables below. We qualified the quality of the different alloys according abrasion and or corrosion resistance to enable a quick selection.
