Silicone products manufacturing is inseparable from the silicone mold, silicone mold quality to some extent also influences the quality of the silicone products, so, silicone mold to meet process performance requirements?
Mould manufacturing is typically after forging, machining, heat treatment, and a few procedure.
To ensure the manufacturing quality of mould, reduce production cost, the materials should have good malleability, cutting machining, hardenability, hardenability and grinding;
Also should have little oxidation and decarburization sensitivity quenching distortion and cracking tendency.
1, malleability, have relatively low hot forging deformation resistance, good plasticity, forging temperature range wide, cold forging crack crack and precipitation carbide network tend to be low.
2, manufacturability, spheroidizing annealing temperature range wide, annealing hardness is low, and the fluctuation range is small, spheroidization rate is high.
3, cutting machining, cutting dosage, low dissipation of cutting tool and the processing surface roughness is low.
4, oxidation and decarburization sensitivity: when heated to high temperature oxidation bosom can good, decarbonization speed slow, is not sensitive to the heating medium, produce pitting tend to be small.
5, hardenability: after quenching is uniform and high surface hardness.
6, hardenability: after quenching can get deeper hardening layer, the ease of quenching medium can be hardened.
7, quenching deformation and cracking tendency: conventional quenching small volume change, shape warping, distortion, mild, abnormal deformation tend to be low.
Conventional quenching cracking sensitivity is low, is not sensitive to quenching temperature and shape of the workpiece.
8, can grinding wheel is relatively low dissipation, grinding dosage, no burn limit is not sensitive to the quality of grinding wheel and cooling conditions are less grinding and grinding cracks.
Baoan medical grade silicone, silicone factory food grade silicone, silicone pad, silicone products, silicone strap, such as all kinds of silicone products, made of pure silicone passed the SGS, FDA, CE, LFGB, DGCCRF such as certification, environmental non-toxic, conform to the international medical grade, food grade standard.
