Foshan City Heng-wei screw screw machinery renovation, professional production of injection molding machines, extruders, blown film machine screw, barrel, with professional production lines, advanced technology, unique screw refurbished many customers receive the recognition and praise. Products of high quality alloy steel (38CrMoAL) or a selection of imported steel H13, after quenching and tempering, forming, grinding, surface nitriding or spraying alloy (Ni), polishing and other processes refined, with high wear and corrosion resistance of the advantages. Currently on the market of engineering plastics with glass fiber volumes continue to increase, as well as a variety of filling material, powder, modified like to add, bakelite, iron and other plastics production, easy to wear screw, barrel, causing Enterprises frequently replaced each screw and barrel high cost. We have a repair screw, barrel equipment and mature technology, turning waste into treasure, the old screw, barrel renovation, renovated screw, barrel concentricity, clearance and new screw, barrel almost the same and more wear-resistant and durable. Screw, barrel repair methods: a cylinder bore grinding machine to a new dimension, and then nitrided screw thread surface coating of high wear-resistant alloy (Ni), and then grinding to fit the new size. Second, wear particularly large, with casement method allows the barrel to achieve the original size of the barrel, the processing method: barrel hinge hole, the hole diameter increased 12-14mm, and then hardened carbide sleeve into the barrel Within (alloy sleeve unilateral thickness 6-7mm), hardness :55-60 degrees, and then bore grinding to original size after grinding to screw spraying alloy original size. Also providing customized, home surveying, design services. Our set of peers the essence of excellence, because we are convinced: Customer success is our future. Excellent quality, perfect service are all Heng Wei screw the common pursuit of people willing to squeeze our products for your gold, silver injection.
