Core characteristics of BMC molds

BMC molds, as key equipment for producing high-performance composite material components, have the following core characteristics:

1. Precise structural design

Accurate parting surface: ensuring uniform filling of the mold cavity and reducing product defects

Exhaust system optimization: effectively preventing bubbles and burns, improving surface smoothness

Demoulding slope design: avoids mold sticking problems and ensures product integrity

2. High quality materials and surface treatment

Mold cavity material: H13, S136, S7 and other mold steels are commonly used to ensure durability

Surface technology: chrome plating, polishing, nitriding and other treatments to extend mold life and reduce maintenance costs

3. Requirements for temperature control system

Temperature range: It needs to be stably controlled at 130-160 ° C to adapt to the curing characteristics of BMC material

Heating method: oil heating, heat transfer plate or mold temperature machine, etc., to ensure temperature consistency

4. Special function configuration

Vacuum assisted system: High end molds are equipped with vacuum systems to enhance the compactness of complex structural components

Low shrinkage rate adaptation: BMC material has a shrinkage rate of only 0-0.5%, and the mold needs to be designed with high dimensional accuracy

5. Process adaptability

Molding method: Supports compression molding, injection molding, and transfer molding, with higher flexibility than SMC molds

Liquidity optimization: Design flow channels and feeding systems based on the fluidity characteristics of BMC bulk materials

These characteristics make BMC molds widely used in the fields of electrical appliances, automobiles, and aerospace, especially suitable for producing precision components with high temperature resistance and high insulation
