Strict Requirements For Medical Mould Temperature

In injection medical moulding, the temperature of the medical mould directly affects the quality and production efficiency of the product. Due to the different performance and moulding process requirements of various plastics, the requirements for medical mould temperature are also different. Generally, the temperature of the plastic melt injected into the medical mould is about 200 ° C. After the melt is solidified into a product, it is demoulded from the mould at about 60 ° C. The temperature reduction is dependent on passing cooling water into the mould to remove the heat. For plastics that require a lower mould temperature (generally less than 80 ° C), such as polyethylene, polypropylene, polystyrene, ABS, etc., only a cooling system is needed, because the temperature of the mould can be adjusted by adjusting the flow of water. For plastics that require a higher mould temperature (80-120 ° C), such as polycarbonate, polyphenylene ether, etc., if the mould is large, the mould heat dissipation area is wide, and sometimes it is not enough to heat the mould by injection of high-temperature plastics, so it is necessary Install a heating device. Some plastic products have high requirements on physical properties, appearance and dimensional accuracy, and the temperature requirements for medical moulds are very strict. Therefore, special medical mould temperature regulators should be designed to strictly control the temperature of each part of medical moulds. The cooling of the medical mould mainly adopts the circulating water cooling method. The heating of the medical mould includes heating of hot water, steam, hot oil and resistance wire. The above is the introduction of the design of the cooling system of the medical injection mould. Heating with hot water, hot oil or steam also needs to set up a heating channel in the medical mould, so it is basically the same as the design of the cooling channel.
