Thermoset Molding Services

Wenzhou Jintong provides high-quality thermoset components for electrical, automotive, and appliance industries. We specialize in the following material molding processes:

• Bulk Molding Compound (BMC)

• Sheet Molding Compound (SMC)

• Phenolic Molding Compounds (PF)

• Melamine (MF)

• Epoxy (EP)

• Urea Resin (UF)

• Unsaturated Polyester Resin (UP)

We operate three distinct molding processes, selected based on part geometry, volume, and performance requirements:

Injection Molding
The most efficient process for high-volume production of complex parts. Free-flowing thermoset materials are injected into a closed mold cavity. With robotic insert loading and fully automated post-treatment, our injection molding lines ensure consistent cycle times and repeatable part quality. Suitable for BMC and other flowable thermoset compounds.

Compression Molding
Ideal for small to medium batch sizes and parts requiring superior surface finish. Material is placed directly into a heated mold cavity and compressed under pressure. Compression-molded parts exhibit higher durability, very low shrinkage, no visible injection gate mark, and excellent dimensional stability. Mold temperature typically ranges from 135°C to 170°C, depending on material formulation.

Transfer Molding
A solution for multi-cavity molds and parts with intricate inserts. Material is preheated and transferred through a runner system into the mold cavity. The friction energy generated during material flow accelerates the curing reaction, resulting in shorter cycle times compared to conventional compression molding.
