Custom Insert Molding Solutions — Bost Engineering Plastics
Custom Insert Molding by Bost — Precision Engineering Plastics
Bost is a professional, innovative high‑tech manufacturer specialising in engineering plastics. Our custom insert molding services integrate advanced mold design, precision mechanical processing and tailored material modification to produce robust components for demanding applications. We focus on quality, rapid turnaround and green manufacturing practices.
Product Overview: Tailored Insert Molding Solutions
Custom insert molding at Bost means embedding metal, ceramic or electronic inserts directly into specially formulated plastic matrices. This process creates strong, durable assemblies that combine the mechanical advantages of steel, rubber or other inserts with the corrosion resistance, wear resistance and thermal performance of our modified engineering plastics.
Materials & Special Properties
We work with a wide range of modified engineering plastics, including ultra-anti‑scar, super corrosion‑resistant, high‑fatigue durable, ultra‑abrasion‑resistant and high‑temperature transparent grades. Additional property enhancements include improved toughness, flame retardance, conductive and thermally conductive formulations, and customized surface finish for assembly or aesthetic requirements.
Applications: Where Custom Insert Molding Excels
Our custom insert molding parts are ideal for automotive components, electrical housings, industrial equipment, medical devices, consumer electronics and steel‑to‑plastic combined structures. Bost’s expertise in multi‑material assemblies enables reliable performance in harsh environments, high load cycles and precision-fit applications.
Why Choose Bost?
Bost combines a high‑level plastics modification R&D team with in‑house mold design, manufacturing and precision machining. Our integrated capability reduces lead time, controls cost and ensures consistent quality from prototype to high‑volume production. We emphasize sustainable processes and customer satisfaction throughout the product lifecycle.
Quality, Customization & Support
From initial concept and material selection to mold tooling, testing and assembly, Bost provides end‑to‑end support for custom insert molding projects. Our quality management and testing processes guarantee dimensional accuracy, mechanical performance and long service life. Partner with Bost for engineered insert molded solutions that meet strict regulatory and performance standards.

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 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.
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
