High quality and durable double alloy screw

High quality and durable double alloy screwZhoushan FuxiangDouble alloy screwIntroducing *'s melt spray welding and centrifugal casting technology and equipment, the imported alloy powder is directly sprayed onto the surface of the screw and the inner hole of the material pipe with high quality and high speed in production. The alloy depth can reach 2.5mm~5mm or more, and the density of the alloy surface is as high as 98%~99.5%. At the same time, the screw temperature is controlled at a low temperature throughout the production process to prevent thermal deformation and brittleness. The adhesion strength of the alloy powder exceeds 10000psi. Therefore, under high torque use, the double alloy screw produced by Zhoushan Fuxiang has *'s characteristics of wear resistance, corrosion resistance, and bending resistance, which can provide services for factories using engineering plastics and corrosive plastics. In addition, our company's dual alloy pipes are divided into three grades: A, B, and C. The alloy contains 40% tungsten nitride; B-class alloy containing 25% tungsten nitride; C-grade alloy contains 9.5% tungsten nitride. All of its materials are made of imported SKD61 high-quality alloy steel.

Sliding of injection molding machine screws can cause material degradation, thereby affecting product quality. What are the reasons for screw slippage? How to 'catch' a slipping screw? Below we will explain to you.

When the screw slips, the material may accumulate at the feeding port and cannot be transported properlyinjection machineThe end. When the screw rotates and retreats inside the barrel to transport materials and prepare for the next injection, screw slippage occurs in the plasticizing section. At this point, the rotation of the screw continues, but the axial movement of the screw will stop, resulting in slippage. Screw slippage often leads to material degradation before injection, resulting in a decrease in product quality (such as material shortage)Molding cycleIt will be extended.

The reasons for screw slippage are multifaceted and may be related tobackpressureIt is related to factors such as excessive height, overheating or undercooling at the end of the material barrel, wear of the material barrel or screw, shallow threads in the feeding section, unreasonable design of the hopper, blockage of the hopper, resin moisture, excessive lubrication of the resin, material being too fine, or unreasonable cutting of resin and recycled materials.
