Bost Custom Insert Molding Solutions for Advanced Engineering Plastics

Custom Insert Molding by Bost — Precision Meets Performance

Product Overview

Bost's custom insert molding services combine state-of-the-art mold design with specialized engineering plastics to embed metal, threaded inserts or functional components directly into plastic parts. Our focus on custom insert molding ensures durable, high-precision assemblies that reduce secondary operations and improve product reliability.

Materials & Special Properties

We offer a range of modified engineering plastics — ultra-high anti-scar, super corrosion resistance, ultra abrasion resistant, super fatigue durable, high-temperature transparent grades and flame-retardant formulations. These materials enhance toughening, thermal conductivity, electrical shielding and wear resistance, making them ideal for demanding insert-molded components.

Capabilities & Process Excellence

Bost's R&D and production teams excel in mold design, prototype to volume production, and precision mechanical processing. Our custom insert molding workflow supports metal-plastic composite parts, steel-plastic combinations and insert fixation methods (heat staking, overmolding, ultrasonic placement) tailored to your product specifications.

Applications & Industry Benefits

Custom insert molding from Bost benefits automotive, medical devices, electronics, industrial equipment and green energy sectors. Integrated inserts improve load transfer, enable threaded connections and increase assembly speed while maintaining tight tolerances and long-term performance.

Quality, Sustainability & Support

Bost is a professional, innovative, high-tech green energy engineering plastics manufacturer committed to R&D, production and sales excellence. We maintain rigorous quality control and offer material traceability, testing and process optimization to meet regulatory and environmental standards.

FAQ:

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.

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 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.
