Bost Insert Molding — Durable, High-Performance Engineering Plastics
Product Overview
Bost insert molding offers a reliable method to combine metal inserts and high-performance engineering plastics into one robust component. Using advanced mold design and controlled processing, our insert molding delivers parts that resist scratches, corrosion, fatigue, and high-temperature conditions while maintaining excellent dimensional stability.
Key Advantages
- Strong metal-plastic bonding: eliminates secondary assembly and improves part integrity.
- Enhanced durability: ultra-abrasion and fatigue resistance extend service life.
- Special properties available: flame retardant, conductive thermal, toughened, and high-temperature transparent formulations.
- Corrosion resistance: ideal for harsh environments and long-term exposure.
- Precision and consistency: tight tolerances from professional mold design and manufacturing.
Practical Value
Insert molding reduces assembly steps, saves cost, and simplifies supply chains. Customers benefit from lighter-weight parts, fewer failure points, and improved product appearance. Our tailored formulations and process controls help you meet performance targets while keeping production efficient.

Q&A
What are the core advantages of Bost engineering plastics compared to ordinary plastics?
Bost engineering plastics feature ultra-high mechanical strength, high-temperature resistance (-50°C to 300°C), chemical corrosion resistance, and wear resistance. Compared to ordinary plastics, their service life is extended by 3 to 8 times, making them suitable for replacing metals in harsh environments.
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
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.
