Bost Custom Injection Molding & Advanced Engineering Plastics
Bost — Leading Custom Injection Molding & Engineering Plastics
About Bost
Bost is a professional, innovative high-tech green energy engineering plastics manufacturer specializing in R&D, production and sales. Since our founding, we have focused on custom injection molding and the development of special engineering plastics to deliver reliable, high-performance parts and materials that meet demanding industry standards.
Core Capabilities
Our capabilities include in-house product mold design, precision mold manufacturing, mechanical processing and advanced plastic modification. With a strong R&D team, Bost enhances toughening, flame retardancy, conductivity and thermal properties on engineered sheets, rods and molded components—tailored through custom injection molding to your exact specifications.
Specialized Materials & Properties
Bost produces materials with ultra-high anti-scar, super corrosion resistance, exceptional fatigue durability, ultra-abrasion resistance and high-temperature transparency. We modify ordinary engineering plastics to achieve conductive, thermally conductive, and impact-enhanced formulations ideal for harsh environments and specialized applications.
Industry Applications
Our custom injection molding solutions serve automotive, electrical, renewable energy, industrial machinery, medical devices and consumer products. We excel at complex steel-plastic and plastic-rubber composite assemblies, enabling durable, lightweight and high-performance components for critical applications.
Quality, Innovation & Sustainability
Bost adheres to rigorous quality control and continuous innovation. Our production teams and advanced processing equipment ensure consistent part tolerances and material performance. Committed to green energy principles, we optimize processes to reduce waste and improve energy efficiency while maintaining product integrity.
Why Choose Bost
Choosing Bost means partnering with an experienced provider of custom injection molding and specialty engineering plastics. We combine technical expertise, end-to-end manufacturing and responsive service to accelerate product development, reduce time-to-market and deliver components that outperform expectations.

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 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).
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.
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.
