1. BMC materials have certain requirements in the process of storage and pressing
First of all, this material is a curable material, and a curing reaction occurs at high temperatures. Therefore, it is necessary to provide suitable environmental conditions during the storage process, and pay attention to controlling the ambient temperature. In fact, BMC material has a limited life, and its molding has a long time, so in order to mold in the shortest time, we must pay attention to the viscosity of the material.
And before using the BMC material, we recommend that the material be returned to room temperature before opening the package to avoid the formation of condensed water, which will affect the processing and performance of the product. It is generally recommended to store the material in a cool and dry environment with the temperature controlled below 25°C, which can effectively ensure its service life. It should be noted that special attention should be paid to safety issues during use.
This is because the BMC material contains some volatile gases and glass fibers, so it is necessary to maintain sufficient ventilation during the molding process to avoid gas accumulation, and to avoid excessive contact with the raw material by human skin. In addition, there are many details that need to be paid attention to in the process of pressing. In the process of pressing, attention should be paid to avoid blowing the exhaust air, fans, etc. directly on the BMC material, and try to keep away from the temperature of the press and mold.
2. BMC materials are widely used
We know that at present, in the process of processing BMC materials, molding, transfer molding, injection molding and other processes are usually used to produce good mechanical properties, good surface finish, water resistance, oil resistance, corrosion resistance, heat resistance, and arc resistance. Up to 190 seconds, it is widely used in electrical, electrical, radio, instrumentation, machinery manufacturing, chemical equipment and other fields.
During use, the material should be reclaimed according to the usage. Be careful not to open all the packaging bags of BMC materials. It is recommended to take the material from the mouth of the bag, and press the mouth of the bag after taking it. Generally, the material required to open the bag should be used within one hour. For the convenience of use, use a plastic box with a lid to place the material, press small products, take 5-10Kg of material each time, put it in the plastic box, and re-tie the bag mouth.
As a leading BMC/SMC molds and BMC/SMC molded products manufacturer in China, Aobang Technology Company Limited provide various products, BMC/SMC molds including but not limited to motor mold, auto parts mold, SMC cable bracket moulding and frame molding; BMC/SMC molded products including but not limited to BMC/SMC motor, SMC auto parts. The high-composite precision molds produced by Waiwai Tree have the characteristics of low energy consumption; our SMC and BMC molds have no waste, and there is no need to clear the inner cavity. Having only a small temperature difference, our SMC/BMC composites have stable mold temperature, good appearance, and high efficiency. Thus, they are now widely used in new energy vehicles, high-speed rail, and electric motors. Feel free to contact us if you have any related need!
