Brief Introduction of Cooling Process in the Process of Alloy Screw


alloy screwIt means that the product material is made of high-quality alloy steel or chromium-molybdenum alloy steel through tempering, shaping, molding, fine grinding, surface nitriding or spray welding alloy (bimetal), polishing and other processes, and has the advantages of high wear resistance and corrosion resistance. Suitable for all kinds of added glass fiber, plastic andPPA,PO,PPS,LCP,ABSFire prevention, bak powder, magnetic powder,PCIt can also be used in plastic molding equipment, such as plastic profile extruders, injection molding machines, etc. With the continuous progress of production technology,alloy screwThe performance of the is also more and more perfect, can be widely used.CNCMachines, CNC lathes, injection molding machines, wire cutting, grinding machines, milling machines, wire walking, fast wire walking,PCBDrilling machine, engraving machine, engraving and milling machine, spark discharge machine, tooth biting machine, planer, large vertical lathe gantry milling machine, etc.

 

alloy screwCooling process during processing:

alloy screwThe cooling and cooling of the homogenization section is due to the large extrusion, friction and shearing effects of the melt in this section, which generates more heat and the temperature rise is faster. In order to prevent the material from decomposing, the temperature needs to be cooled. When extruding materials, it is necessary to cool the alloy screw, mainly to ensure the smooth production. To prevent the material due to plasticizing temperature is too high and cause decomposition. such as inalloy screwThe cooling of the feeding section is to prevent the temperature of the screw in this section from being too high, and to prevent the material from being attached to the thread groove of the screw due to high temperature and rotating with the screw, thus affecting the forward movement of the material conveying and causing the normal production to be unable due to insufficient feeding.

 

Right.alloy screwThe method of cooling and cooling is to pass water or oil in the screw drilled with an axial hole to cool down as a thermal medium. The heat conduction medium should be controlled at a constant temperature, and it should be directly connectedalloy screwThe homogenization section of the, rotating during work.alloy screwA special pipe fitting is required to connect with the heat transfer medium pipeline. This special connecting piece is called a rotary joint.
