Bost Custom CNC Machined Parts — Advanced Engineering Plastics
Bost Custom CNC Machined Parts — Precision Engineering Plastics
Bost is a professional, innovative high-tech manufacturer specializing in R&D, production and sales of engineering plastics. We provide precision custom cnc machined parts made from specially modified sheets, rods and molded components. Our materials include ultra-wear-resistant, super corrosion-resistant, high-temperature transparent, flame-retardant and enhanced-toughness plastics optimized for demanding industrial applications.
Why Choose Bost for Custom CNC Machined Parts
Our experienced plastics modification R&D team and advanced production lines deliver consistent tolerance, excellent surface finish and long service life. Bost combines expertise in steel-plastic and plastic-rubber composite solutions, enabling integrated components with superior mechanical and thermal properties. We support both rapid prototyping and scalable production runs, ensuring timely delivery without compromising quality.
Materials & Capabilities
Bost produces and machines a wide range of specialized engineering plastics: ultra-high anti-scratch, abrasion-resistant, fatigue-durable, conductive and thermally conductive grades, and high-temperature transparent polymers. We offer custom machining of sheets, rods and molded parts with full mold design and manufacturing, CNC milling, turning, drilling and precision finishing tailored to specific tolerances and surface requirements.
Applications
Our custom cnc machined parts serve aerospace, automotive, green energy, medical devices, semiconductor, and industrial machinery sectors. Typical applications include structural components, seals, wear pads, insulation parts, heat-dissipating elements and multi-material assemblies where plastic-to-metal bonding or composite construction is required.
Quality, Sustainability and Support
Bost emphasizes green energy practices in production and maintains rigorous QA protocols to ensure consistent mechanical and chemical performance. We provide material selection guidance, CAD review, rapid prototyping, pilot runs and full-scale manufacturing. Technical support extends from part design optimization to post-production inspection and logistics.

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 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.
