BMC/SMC Molds

Custom high Precision Compression/Injection Moulds Manufacturing with fast lead time



BMC/SMC Mould Manufacturer



We mainly use injection molding and pressure molding as the methods. When designing the flow channel and parting surface, we think that the cavity pressure should be as small as possible, especially some small ribs, as well as the smooth exhaust, the discharge position, shape, and material flow direction, which would all be fully considered. And the active exhaust must be complete with an overflow. We guarantee the appearance and strength. With the Vacuuming structure, the mold temperature balance is consistent as the appearance and strength of the product shall be guaranteed as well.



We are professional sheet molding compound manufacturers and sheet molding compound suppliers. We provide you with SMC injection molding and BMC injection molding. You can know difference between SMC and BMC from us.



Types of BMC/SMC Molds

Motor Mold

Motor Mold is designed mainly for injection molding with the runner and parting surface would be precisely small.



High Voltage Electrical Product Mould

High Voltage Electrical Product Mould is a featured products and the mold temperature can be balanced with a vacuum sructure.



Low Voltage Electrical Appliance Mould

Low Voltage Electrical Appliance Mould is mainly used for pressure molding and for the movable exhaust and designed with a overflow trough.



Auto Parts Mould

Auto Parts Mould sloves the problem of ligh-weight, aging and other leakage issues as well as reduces more costs but improves the quality.



Frame Moulding

Frame Moulding has high plasticity with a precise size but high insulation ability and high temperature resistance.

Difference Between SMC and BMC

Difference Between SMC and BMCSMC is a combination of long chopped glass strands, mineral fillers and liquid thermosetting resin in the form of a malleable sheet material. Processing of SMC of is typically done by compression or injection molding.

Sheet Molding Compound SMC is a compression molding compound often used for larger parts where higher mechanical strength is needed. SMC is a fiber reinforced thermoset material. Glass reinforcement is between 10% and 60%, and glass length is slightly longer than Bulk Molding Compound BMC - between 1/2-inch and 1-inch 25mm.



BMC is a combination of short chopped glass strands, mineral fillers and liquid thermosetting resin in the form of a bulk material. BMC is suitable for either compression or injection molding.

Bulk Molding Compound BMC is a thermoset plastic resin blend of various inert fillers, fiber reinforcement, catalysts, stabilizers, and pigments that form a viscous, 'puttylike' injection molding compound. Bulk Molding Compound BMC is highly filled and reinforced with short fibers. Glass reinforcement represents between 10% and 30%, with glass length typically between 1/32-inch and 1/2-inch 12.5mm.

SMC Material Compression Molding Processes

SMC Material Compression Molding ProcessesThe basic process of the compression molding process is to place a certain amount of the pre-treated molding material into a preheating compression mold, and apply a higher pressure to fill the mold cavity with the molding material. Under the predetermined temperature conditions, the molding material is gradually solidified in the cavity, and then the SMC product is taken out from the stamper, and the necessary auxiliary processing is performed to obtain the final product.



The pressing process of the composite molded product is a process of solidifying into a product in a cavity after the binder is loaded or heated under the condition that the curing agent is present or heated. Molding temperature, molding pressure and mold exhaust, temperature balance, and mold structure all affect the quality of SMC products. It is necessary to determine the best solution under the consideration of various influencing factors.
