Bost Insert Injection Molding – Reliable Overmolding Solutions

What is Insert Injection Molding?

Insert injection molding is a manufacturing method where metal or pre-formed components are placed into a mold and plastic is injected around them to form a single, integrated part. This process creates strong, sealed assemblies with excellent mechanical and thermal performance. Bost applies its deep expertise in engineering plastics to deliver parts that meet demanding industrial standards.

How Bost Does It Differently

At Bost, we combine advanced material science with precise mold design and experienced production teams. Our focus on modified engineering plastics—such as high-heat, abrasion-resistant, and corrosion-resistant grades—ensures that insert molded parts stand up to tough environments. We also provide enhanced properties like improved toughness, flame retardancy, and thermal conductivity when required.

Key Benefits of Bost Insert Injection Molding

• Strength and Durability: Overmolded parts produced by Bost resist fatigue, wear, and impact.
• Corrosion and Temperature Resistance: Suitable for harsh environments and high-temperature applications.
• Precision and Consistency: Tight tolerances and repeatable results thanks to advanced molds and quality control.
• Improved Functionality: Integrated seals, electrical insulation, or conductive paths can be built into a single part.
• Cost-Effective Production: Combines multiple components into one assembly, lowering assembly time and cost.

Typical Applications

Bost insert injection molding serves industries such as automotive, electronics, renewable energy, medical devices, and industrial equipment. Common parts include threaded inserts, metal-to-plastic housings, sensors, connectors, and structural components requiring combined material properties.
