BMC is the abbreviation of glass fiber reinforced unsaturated polyester thermosetting plastic, and it is currently the most used type of reinforced thermosetting plastic. The advantages of BMC injection moulds are mainly reflected in the following points:


Ⅰ. Features and applications of BMC injection moulds


BMC injection moulds have good physical, electrical and mechanical properties, so they are widely used, such as making mechanical parts such as gearbox components, intake pipes, valve covers, bumpers, etc.; they are also widely used in aviation, construction, furniture, etc. that require anti-know performance, flame retardancy, beauty, and durability; in other traditional electrical appliances fields, their uses are becoming more and more extensive.


Ⅱ. Systems of BMC injection moulds


BMC's injection mold molding equipment is a dedicated BMC injection molding equipment. Due to the addition of glass fiber, the equipment used is somewhat different from the usual thermosetting plastic injection molding equipment. The injection molding machine used can be either plunger or screw.


1. Feeding system. Regardless of the screw type or the plunger type, an extrusion type feeding device must be added to force the material into the barrel. The feeding device mostly adopts the plunger type pressure feeding and the screw feeding.


2. Injection molding system. Because the injection volume of the plunger injection molding machine is accurate and constant, the glass fiber is dispersed in the melt with less damage. Therefore, the plunger injection molding machine is used more, but the screw material and the matching schedule are very demanding.


3. Heating system. In BMC injection molding, it is very important to control the temperature of the barrel. There must be a set of control system to control the temperature to ensure that the temperature from the feeding section to the nozzle is the best. At present, constant temperature water or constant temperature oil is often used for control.
