What Is BMC(Bulk Molding Compound) Mold​

What is BMC(Bulk Molding Compound) Compression Mold

BMC (Bulk Molding Compound) compression mold, also known as a BMC compression molding tool, is a specialized mold used in the manufacturing process of components made from Bulk Molding Compound (BMC). BMC is a type of thermosetting composite material that consists of a mixture of thermosetting resin, chopped glass fibers, mineral fillers, and various additives. It is commonly used in industries such as automotive, electrical, and appliance manufacturing for producing parts with high mechanical strength and dimensional stability.

BMC mold is a high-energy tool widely used in the plastic molding industry. Its unique design and advanced technology make the production process of plastic products easier and more efficient, while also improving product quality and reliability.

At present, BMC molds have been used in automobiles, energy, electrical appliances, catering services, household appliances, optical instrument components, industrial and construction supplies and other fields. WS Mold is engaged in the design and manufacturing of hot pressing molds for BMC composite molding molds, and has developed a variety of BMC mold products, such as fiberglass automotive parts, composite manhole covers, electrical boxes, meter boxes, etc.

WS (WINSEN) is a processing enterprise specializing in the production of BMC composite molds and products, providing customers with composite mold products and application solutions.

BMC materials have excellent physical and chemical properties, making them an excellent material for many composites products. The BMC mold is a tool specially used to process BMC parts.BMC molds are usually made of metal materials, such as steel. The cavity inside the mold is designed to match the shape of the final product. During the manufacturing process, BMC material is added to the mold, and then high pressure is applied through hot or cold pressing to fill the entire mold cavity. After a certain period of curing, the mold is opened and the molded BMC product can be obtained.

What is BMC Mold Forming Process

BMC (Bulk Molding Compound) mold is a tool used to manufacture BMC composite products. BMC molds are formed by compression molding. Compression molding is a method of shaping thermosetting materials by applying both intense pressure and elevated temperature to achieve the desired form.

The following is the process of BMC mold forming:

  • Material Preparation: BMC material is prepared by mixing the various components to create a uniform compound.
  • Material Compression: The prepared BMC material is placed into the mold cavity.
  • Mold Closure: The BMC molds are typically made of steel, is closed to enclose the BMC material.
  • Molding and Curing: The closed mold is subjected to both heat and pressure. The heat causes the thermosetting resin in the BMC material to cure and harden, while the pressure ensures the material takes on the mold’s shape.
  • Cooling: After curing, the mold is cooled to solidify the part.
  • Mold Opening: Once the part has fully cured and solidified, the mold is opened, and the finished component is removed.

As an advanced mold manufacturing technology, BMC mold is gradually becoming the precision choice in the industrial field.BMC is a thermoset plastic that is mixed with various inert fillers, fiber reinforcements, catalysts, stabilizers and pigments to form a sticky “putty-like” composite for compression or injection molding. BMC has many unique properties, such as high hardness, light weight, corrosion resistance, UV resistance, good insulation, excellent thermal properties, etc., which make BMC more satisfactory than thermoplastics.

The compression molding process uses the characteristics of each stage in the resin curing reaction to achieve product molding, that is, the molding material plasticizes, flows and fills the mold cavity, and the resin solidifies.
