Bost Custom Overmolding Solutions for High‑Performance Engineering Plastics
Custom Overmolding Solutions by Bost
Overview
Bost is a professional and innovative high‑tech green energy engineering plastics manufacturer specializing in research, development, production and sales. Our custom overmolding services integrate material science and precision molding to create durable, functional, and aesthetically refined components for demanding applications.
Materials & Performance
We tailor material formulations—ultra‑high anti‑scar, super corrosion‑resistant, fatigue‑durable, ultra abrasion‑resistant, high‑temperature transparent and conductive/thermal composites—to match product requirements. Custom overmolding with Bost ensures that seals, grips, housings and interfaces achieve optimal adhesion, longevity and targeted mechanical or electrical properties.
Design & Manufacturing Expertise
Our experienced R&D and production teams excel in mold design, steel‑plastic integration, and mechanical processing of complex parts. From concept to finished part, Bost delivers precise overmolded assemblies with exact tolerances, multi‑material bonding and repeatable cycle performance. Rapid prototyping and pilot runs speed time‑to‑market without compromising quality.
Applications
Custom overmolding by Bost serves electronics, green energy, automotive, medical devices, industrial equipment and consumer products. We specialize in combinations like steel‑to‑plastic and plastic‑to‑rubber overmolds that improve impact resistance, sealing, vibration damping and thermal management.
Quality, Compliance & Sustainability
Bost maintains strict quality control and material traceability, integrating flame retardancy, toughening and conductive additives as required. Our green energy focus drives sustainable material choices and energy‑efficient production processes to reduce environmental impact while meeting global regulatory standards.
Why Choose Bost
With deep expertise in engineering plastics modification and full in‑house capability—from mold making to mechanical finishing—Bost provides turnkey custom overmolding solutions that balance performance, cost and manufacturability. Contact us for material selection, prototyping and volume production support.

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.
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.
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.
