Bost Custom Plastic Injection Molding — Advanced Engineering Plastics
Custom Plastic Injection Molding by Bost
Company Overview
Bost is a professional, innovative, high-tech green energy engineering plastics manufacturer specializing in R&D, production and sales. Since establishment, Bost has focused on delivering high-quality custom plastic injection molding solutions and special engineering plastics to ensure customer satisfaction across industries.
Why Choose Our custom plastic injection molding
We combine deep material science with precision mold-making to produce parts with superior properties — ultra-high anti-scar, extreme corrosion resistance, fatigue durability, abrasion resistance, high-temperature transparency, flame retardancy and enhanced toughness. Our marketing-driven approach ensures fast turnaround, competitive pricing and product designs optimized for manufacturability and performance.
Materials & Capabilities
Bost formulates and modifies polymers to deliver conductive, thermally conductive, wear-resistant and specially toughened engineering plastics. We supply sheets, rods and molded components using advanced compounding and injection techniques. Our capabilities include multi-material overmolding, steel-plastic assemblies and precision mechanical processing to meet tight tolerances.
R&D, Tooling & Production Excellence
Our experienced plastics modification R&D team and production engineers handle mold design, manufacturing and mechanical processing in-house. This integrated workflow reduces defects, accelerates sample cycles and ensures high repeatability for large-volume custom plastic injection molding projects.
Quality, Sustainability & Compliance
Bost implements strict quality control and sustainable practices across production. We focus on energy-efficient processes, recyclable materials where possible, and compliance with international standards to support customers seeking greener engineering plastic solutions.
Applications & Customer Support
From automotive and electronics to renewable energy and industrial equipment, our specialty engineering plastics are designed for demanding environments. Bost offers technical consultation, prototyping, and post-production support to ensure each custom plastic injection molding program meets performance and business goals.

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 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.
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.
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.
