Three abrasives and three solutions
The compression ratio, fluidity and demoulding characteristics of different abrasives in the molding process are significantly different. According to the physical and chemical characteristics of each abrasive, Shandong Hengtai Mould has established a differentiated mould technology system: White Fused Alumina: White corundum abrasive has high hardness and regular particle shape, which requires extremely strict mold accuracy. Hengtai mold adopts high wear-resistant alloy steel and precision grinding technology to ensure that the surface roughness of the mold cavity reaches below Ra0.4, effectively avoiding the problem of edge cracking during the molding of White Corundum Grinding Wheel, and at the same time greatly improving the reuse times of the mold. Brown corundum: Brown corundum has good toughness and high molding pressure. In view of this characteristic, Hengtai Mould optimized the design of reinforcing rib structure and stress distribution of the mould, so that the large-size Brown Corundum Grinding Wheel was uniformly stressed in the pressing process and the deformation rate of the product was significantly reduced. Silicon carbide: Silicon carbide abrasive has extremely high hardness and strong self-sharpening, but it wears the mold quickly during molding. Hengtai Mould takes the lead in introducing bimetallic composite mould sleeve technology in this field, and the working layer and non-working layer are selected separately, which not only ensures the cavity accuracy, but also prolongs the overall service life of the mould by more than 25% compared with the traditional scheme. From Shandong to the world
After more than 30 years of continuous cultivation, Hengtai Mould has accumulated molding data covering thousands of grinding wheels of different specifications. The company has established a complete manufacturing chain from mold design, blank forging, precision machining to vacuum heat treatment, ensuring that each set of grinding wheel mold has undergone strict three-coordinate detection and mold test verification. "The mold is the' skeleton' of the abrasive. If the skeleton is not straight, even the best abrasive can't make a good grinding wheel." The technical director of Shandong Hengtai Mould Co., Ltd. said, "What we do is not only to process the mould to the drawing size, but also to understand how the white corundum flows, how the brown corundum is pressed, how the silicon carbide is removed, and turn the mould into the guarantee of abrasive performance." With solid product quality and stable delivery capacity, Hengtai Mould's products have been widely used in many abrasive and abrasive industrial bases in China, and gradually expanded to Southeast Asia, the Middle East and South America. The company's latest universal quick-change mold base can realize the quick switching of molds with different specifications and different Abrasive Wheels, help customers shorten the production line changing time by more than 40%, and significantly improve the profitability of small and medium-sized multi-variety orders.
