BMC Molding Material

BMC material is a bulk molding compound composed of glass fiber and unsaturated resin.

Insulation & Fireproofing
High-Temperature Resistance
UV Resistance & Waterproof
High Impact & Tensile Strength

It maintains excellent performance in both cold and hot environments, making it suitable for outdoor applications with UV resistance and waterproofing functions.

With stable dimensions and minimal shrinkage, it can be used in products with complex structures.

It is widely applied in industries such as home appliances, industrial electrical equipment, aerospace, new energy, automotive, and construction.

BMC Injection Molding Manufacturer

Tooling

With 20 years of experience in BMC injection mold design, Yongchao optimize parting lines, ejector pin positions, heating systems, mold core thickness, slider structures, and core-pulling mechanisms.

To separate runners from products, we use in-mold cutting technology to reduce manual runner processing.

To minimize runner waste, save material costs, and reduce environmental pollution, we use valve gating design, resulting in lower product costs, shorter injection times, and better product strength.

Molding

With over 20 years of injection molding experience, we excel in debugging different molds and product structures.

  • Molds utilize a cold runner system.
  • Vacuum technology is applied during molding.
  • Injection molding capabilities.
  • Injection-compression molding increases product strength by 15% compared to standard injection molding.
  • Transfer molding preserves glass fibers in the barrel, achieving strength close to that of compression molding.

Injection Machine

Traditional screw-type injection machines can damage glass fibers. Therefore, we collaborated with machine suppliers to develop a new type of machine—a transfer machine without a screw—to achieve optimal product strength.

The machine barrel is equipped with a preheating system (50-60°C), improving material preheating for better molding, product appearance, and strength.

Why Choose BMC Injection Molding?

BMC injection molding has been recognized and licensed by international manufacturers in aerospace, automotive, truck, high-speed rail, medical, and other industries.

We provide customers with solutions for composite material applications, along with feasibility analysis and technical support for new product development.

BMC is available in various colors to meet different consumer market demands. It can also be produced using in-mold coating technology for integrated manufacturing based on customer requirements.

Frequently Asked Questions

What is BMC molding material?
BMC (Bulk Molding Compound) is a composite material made of glass fiber and unsaturated resin. It offers excellent electrical insulation, high-temperature resistance, fireproofing, UV stability, and high mechanical strength.
Why is BMC injection molding better than compression molding?
BMC injection molding is faster, more efficient, and more cost-effective. It allows for the production of more complex parts and structures with highly stable dimensions and minimal shrinkage.
How does Yongchao optimize the tooling process for BMC molds?
Yongchao optimizes parting lines, heating systems, and core structures. We use in-mold cutting to reduce manual labor and valve gating design to minimize runner waste and material costs.
How does Yongchao prevent damage to glass fibers during injection?
To prevent damage to glass fibers caused by traditional screw-type machines, we co-developed a screw-free transfer machine that preserves fiber integrity and ensures optimal product strength.
Can BMC injection molded parts be used outdoors?
Yes. BMC maintains excellent performance in both cold and hot environments, featuring high UV resistance and waterproofing functions, making it ideal for outdoor applications.
