BMC molding
BMC parts for heat, insulation and tight dimensions
BMC suits smaller, detailed parts that need heat resistance, electrical insulation and low shrinkage. Injection molding is the efficient route in volume; compression molding is used for thick sections and lower volumes.
Reflectors are molded with a high-gloss surface, then base-coated and metallized. Electrical parts are usually molded in a flame retardant grade with a stated UL 94 rating and tracking resistance (CTI). Tell us which requirements apply and we will propose the grade.
Typical BMC parts
- Headlamp and lamp reflectors
- Circuit breaker and switch housings
- Motor housings and end caps
- Electrical insulators and terminal blocks
- Heat-resistant appliance parts
- Parts with molded-in metal inserts
BMC parts FAQ
Why is BMC used for headlamp reflectors?
BMC keeps its shape at high temperatures, shrinks very little and can be molded with a smooth, glossy surface that takes a base coat and metallizing. Together that gives an accurate reflector that stays stable when the lamp is hot.
Is BMC flame retardant?
Flame retardant BMC grades are available and widely used for electrical parts. A rating such as UL 94 V-0 applies to a specific grade at a specific thickness, so the grade is chosen to match your requirement.
