About SMC Mould

Molding molds usually use a hydraulic press, and the upper and lower parts of the mold are fixed to the press. The mold includes a cavity core, which is the same as the injection mold. The test material is placed on the open mold and the press is turned off. The set temperature and the pressure generated by the press melt the raw material into the cavity of the mold.

SMC mold is a FRP mold, hot pressing mold, the inside of the mold is 175-190 degrees of hot oil, put the sheet-like material into the mold, the mold is melted by the hydraulic machine, the product is formed, the material is thermosetting, that is Once formed, it cannot melt again. Like the high-end Rolls-Royce bumper, the Land Rover tailgate, the front and rear of the large car, the side panels of the train carriage are all FRP molds.

The SMC mold mainly considers the flash, the scrap is not good, and the press can't be pressed. Therefore, the sealant is straight face. He does not insert the bevel as the injection mold, and the SMC is straight. Moreover, the thermal expansion deformation of the mold should be considered. Basically, for every 1 degree increase, the deformation of the steel of 1 meter is 0.012, so it is also a problem to consider the deformation displacement of the ejector. Otherwise it will be stuck.

The high-end molds are all vacuumed. It is the air that can't be discharged when the mold is closed. Closely sealed with a sealing strip, screw on the interface of a fire hydrant, pump the air, press down, so that it will not be trapped, not full.

The correct selection and determination of SMC materials is a prerequisite for achieving the accuracy of the design product. In order to combine the performance characteristics and process characteristics of SMC materials, the most economical materials are selected on the basis of satisfying the performance of the products.
