1. SMC mould standardization system

The temperature of mold design is usually between 140-160 °C. When planning the temperature system of the mold, attention should be paid to keep the temperature of the entire surface of the mold the same. The uniformity of temperature can reduce deformation, increase dimensional stability, and the uniformity of product appearance. , The manufacturability evaluation mainly includes mold planning and manufacturing cost budget, mold installability evaluation, mold parts manufacturing process evaluation, mold structure and forming function evaluation, etc. The standardization of SMC moulds mainly includes the formulation and implementation of technical specifications, the production and use of standard parts, and the promotion, compliance and promotion of relevant standards.

The SMC mould standardization system includes four categories of specifications, namely: basic specifications, process quality specifications, component specifications and production-related technical specifications. According to its main classification, it can be divided into ten categories such as stamping SMC mould specifications, die-casting SMC mould specifications, casting SMC mould specifications, cold extrusion SMC mould specifications, rubber SMC mould specifications, glass product SMC mould specifications, and automotive stamping mold specifications. According to the SMC mould standard, the use of standard parts can not only increase the quality of the mold, but also reduce the cost of mold production and greatly shorten the mold production cycle.

2. The method to solve the unstable pressure of SMC mould temperature machine

SMC mould temperature machines are generally used in SMC industries, such as glass fiber reinforced plastic molding molds, thermoset molding molds, glass fiber reinforced plastic molding molds and other SMC industries. It uses heat transfer oil for circulating heating, the temperature is 300 ℃, and it can also be customized to integrate two machines and control the temperature of the upper and lower molds. Suitable for FRP auto parts, boats, septic tanks, water storage tanks, etc. SMC mould temperature machine is a device used for mold temperature control in compression molding. When you use it for the first time, you will definitely encounter various problems. The more common one is how to solve the problem of unstable pressure of SMC mould temperature machine?

The pressure instability of the SMC mould temperature machine is generally caused by two reasons, such as gas in the system pipeline. There is water in the system piping. This is the main reason for the instability of pressure. When the pressure of the SMC mould temperature machine is unstable due to the air in the piping system, what needs to be done is to open the mold temperature machine circulation pump to circulate it. The pump is in working condition, so a mold temperature machine can be used to achieve venting. In another case, there is water in the system piping. This is more troublesome. You need to set the temperature of the mold temperature machine to about 90°C and observe if the pressure gauge is stable. If the temperature is increased by 2°C until the pressure stabilizes, the operations will be performed sequentially. Until the temperature of the mold temperature machine reaches the set requirements. The reason is to use the boiling point of water at 100°C under normal atmospheric pressure to evaporate the water in the pipe and then discharge it.
