About the Exterior Strengthening of tungsten Carbide Dies
Zhuzhou pintejin Cemented Carbide Co., Ltd specializes in the production of tungsten carbide dies and has a certain say in the quality improvement of the products.
About the exterior strengthening, different strengthening methods should be used according to the dies of different uses. For example: punching die can use EDM reinforcement, carbide overlay welding, etc., in order to improve the wear resistance and compressive strength of the surface layer of mold parts; die-casting die, plastic die and other hot processing mold steel parts can be used nitriding (hard nitriding) disposal, in order to improve the wear resistance of the parts, heat-resistant fatigue and corrosion resistance; deep drawing die, bending die can be used sulfurization disposal, in order to reduce the friction coefficient, improve the wear resistance of the material; carbon nitriding (soft nitriding) can be applied to the appearance of various types of mold strengthening treatment. In addition, in recent years, a kind of development called fcva vacuum diamond film technology, can constitute a layer in the surface layer of the parts and the substrate separation is exceptionally strong and very lubricating average dense maintenance film, this technology is particularly suitable for mold appearance maintenance disposal, is also to improve the quality of tungsten carbide mold a significant effect of the method. Of course, if the product is a trial product or consumption batch is quite small, it is not necessary to stop the appearance of mold parts to strengthen the disposal.
For the quality of the product, Zhuzhou pintejin has always focused on, so with Zhuzhou State Investment Jinhui testing center cooperation. We are committed to providing better service and product quality for our customers.
