Product introduction

High-performance injection molding machine alloy barrel manufacturers use high-quality gold-containing steel (38CrmoALA), which is precisely manufactured through adjustable quality and qualitative, surface nitriding, and polishing processes, and has the characteristics of precision wear resistance.

Detailed introduction

High-performance injection molding machine alloy barrel manufacturers barrel material
In order to meet the working requirements of the barrel, it must be made of high-quality high-temperature, wear-resistant, corrosion-resistant, high-strength materials. These materials should also have good machinability and heat treatment properties. In addition to 45 # steel, 40Cr, 38CrMoAL, the barrel can also be made of cast steel and ductile iron. The feed section with bushing can be made of high quality cast iron.
Status of high-performance injection molding machine alloy barrel manufacturers:
In recent years. With the development of high-speed extrusion and engineering plastics, especially when extruding glass fiber reinforced plastics and plastics containing inorganic fillers, higher requirements have been placed on the abrasion and corrosion resistance of barrels. The Xaloy alloy developed by the United States and the United States is a new type of wear-resistant and corrosion-resistant material, and is currently widely used abroad. This material has a melting point di, hard, has good weldability with steel, good machinability, good casting performance, and no casting stress. Even if it is bent after casting, it will not fall off like scales.
It is applied to the barrel by adopting this method: The powdery Xaloy alloy is heated together with the barrel at a high temperature. Due to its melting point di, it can be melted into a flowing state at about 1200 ° C. At this time, The barrel rotates at a high speed, and the huge centrifugal force generated by the molten Xaloy makes it cast on the inner wall of the red-hot barrel. Its thickness is about 2 mm. After cooling, it is ground by grinding to remove about 0.20 mm. Requirements of the cylinder.
According to reports, a Xaloy alloy produced in Belgium has a hardness value of Rc58-64. At 482 ° C, the hardness is not significantly reduced, and the corrosion resistance is 12 times greater than that of nitriding steel.
