Custom Plastic Injection Molding Solutions by Bost

Bost – Custom Plastic Injection Molding Solutions

Bost is a professional, innovative high‑tech manufacturer of green energy engineering plastics. We specialize in custom plastic injection molding to deliver precision parts with specialized properties—ultra abrasion resistance, super corrosion resistance, high temperature transparency, enhanced toughness, flame retardancy and thermal conductivity. Our approach combines material science with full-service tooling and production to ensure consistently high quality and on-time delivery.

Precision Engineering & Material Innovation

Our materials R&D team develops tailored polymer formulations and modifications for custom plastic injection molding projects. From modified sheets and rods to tailored mold compounds, we optimize mechanical performance, fatigue durability and surface finish to meet demanding specifications in automotive, electronics, energy and industrial sectors.

Specialized Properties & Applications

Bost produces special engineering plastics with unique performance: ultra high anti‑scarring, super corrosion resistance, ultra abrasion resistant, conductive and high temperature transparent grades. These materials are ideal for wear parts, housings, seals, insulating components and combined steel‑plastic assemblies where standard polymers fail.

End-to-End Production & Tooling

We offer complete custom plastic injection molding services including mold design, manufacturing, trial runs and full-scale injection production. Our mechanical processing capabilities and integrated steel‑plastic, plastic‑rubber hybrid manufacturing ensure precise assemblies and repeatable tolerances across large runs.

Sustainability & Quality Assurance

Bost integrates green energy principles into manufacturing and selects recyclable, low‑impact materials where possible. Our quality systems monitor performance, dimensional control and material properties to deliver parts that meet regulatory and customer standards.

Why Choose Bost

With deep expertise in modified engineering plastics and a strong production team, Bost provides reliable, high‑tech custom plastic injection molding solutions that reduce time‑to‑market and improve product longevity. We partner with customers to solve complex material and manufacturing challenges.

FAQ:

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).

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 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.

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.
