Molds for transparent products needs to be made of polished steel. This will often make your inventory unable to be demoulded, inducing quality problems. Inadequacies in any part in the thermal mold may make it suffer from large temperature variances or runaways between operations. On large molds, it is an economical heating method if the oil temperature is controlled in addition to heated. One of the keys is to evenly distribute the temperature field through the entire mold to promote uniform curing belonging to the LSR. When designing high have on material molds, those parts that are put through high friction should be which is designed to be replaceable so that your whole mold does not should be replaced. The inner surface with the cavity has a great influence to the finish of the product. 2379, DINcodeX155CrVMo121) specially developed with this purpose.. In normal, the molding of the LSR can be preferably performed by electric warming up, which is usually carried out with a ribbon heater, a cartridge heat tank or a food container mould heating plate. When the surface temperature drops too lower, the cure speed of the rubber material will decelerate. Outside treated Chin/Ni steels have extremely high wear resistance, while PTFE/nickel clarifies that it's easier to release
