Product Information
What is Custom Insert Molding?
Custom insert molding is the process of molding plastic around pre-placed inserts—metal, threaded components, sensors or other parts—to create a single, durable assembly. Bost combines advanced materials and precision tooling to deliver reliable, high-performance products for demanding industries.
Why Choose Bost?
Bost is a professional, innovative and green-energy focused engineering plastics manufacturer. With a strong R&D team and in-house mold design and manufacturing, we provide end-to-end solutions from material selection to finished parts. Our experience with special engineering plastics—such as anti-scratch, ultra-corrosion resistant, high fatigue durability, high-temperature transparent, flame-retardant and thermally conductive grades—makes us uniquely qualified to solve complex design challenges.
Key Advantages
- Secure, reliable metal-to-plastic bonding that reduces assembly steps.
- Excellent resistance to wear, corrosion, heat and chemicals for long service life.
- High precision and repeatability for tight tolerances and complex geometries.
- Support for a wide range of materials and property enhancements—toughening, flame retardance, conductivity.
- Fast prototyping, scalable production from small runs to mass manufacturing.
Applications
Bost custom insert molded parts are ideal for automotive components, electrical connectors, consumer electronics housings, medical devices, renewable energy systems and industrial equipment. Our steel-plastic and plastic-rubber composite expertise enables lightweight, high-strength assemblies that perform in harsh environments.
How We Work
We begin with a detailed review of your design and performance requirements, recommend optimal materials, and design molds for efficient insert placement. Prototypes are validated quickly, then production is optimized for cost and quality control. Bost’s integrated capabilities—tooling, molding, machining and finishing—ensure faster lead times and consistent results.

FAQ
How do I select the appropriate engineering plastic grade for my product?
Selection should be based on parameters such as load conditions (e.g., pressure/friction), temperature range, medium contact (e.g., oil/acid), and regulatory requirements (e.g., FDA/RoHS). Our engineers can provide free material selection consulting and sample testing.
What is the delivery lead time? Do you offer global logistics?
Standard products: 5–15 working days; custom modifications: 2–4 weeks. We support global air/sea freight and provide export customs clearance documents (including REACH/UL certifications).
Can Bost customize modified plastics with special properties?
Yes! We offer modification services such as reinforcement, flame retardancy, conductivity, wear resistance, and UV resistance, for example:
• Adding carbon fiber to enhance stiffness
• Reducing the coefficient of friction through PTFE modification
• Customizing food-grade or medical-grade certified materials
What is the minimum order quantity (MOQ)? Do you support small-batch trial production?
The MOQ for standard products is ≥100kg. We support small-batch trial production (as low as 20kg) and provide mold testing reports and performance data feedback.

Insert molding solutions for plastic mould manufacturer
Insert molding is an injection molding process where pre-fabricated components, such as metal inserts, electronic parts, or other plastic elements, are placed into the mold cavity before molten plastic is injected around them. This bonds the insert with the plastic, creating a single, integrated part.

Custom Overmolding mould-BOST rubber and plastic supplier
Over molding is an advanced injection molding process that involves molding a second material over a pre-formed substrate, typically called the "carrier" or "base" part. This technique bonds two or more materials together, creating a single, multi-component product with enhanced functionality and aesthetics.
Nylon Plastic Worm Gear custom for transmassion device
Nylon plastic gears have emerged as a preferred choice in modern manufacturing due to nylon's exceptional material properties. Nylon, a type of synthetic thermoplastic polymer, boasts high strength, excellent abrasion resistance, and low friction coefficients. It also exhibits good chemical resistance to various solvents, fuels, and lubricants, while maintaining dimensional stability across a wide temperature range. Additionally, nylon's self-lubricating nature reduces the need for external lubricants, simplifying maintenance.
