Custom CNC Machined Parts for High-Performance Engineering Plastics
Custom CNC Machined Parts — Precision Engineered by Bost
Why Choose Bost for Custom CNC Machined Parts
Bost is a professional, innovative high‑tech manufacturer of engineering plastics, committed to R&D, production and sales. Our custom CNC machined parts combine advanced material science with precise machining to deliver components that outperform metal and standard plastics in wear resistance, corrosion protection, fatigue life and thermal stability.
Advanced Materials and Special Properties
We specialize in sheets, rods and molded components made from ultra‑high anti‑scar, super corrosion resistance, super fatigue durable, ultra abrasion resistant and high‑temperature transparent engineering plastics. Bost enhances toughness, flame retardancy, conductivity and thermal properties through proprietary modification, producing custom CNC machined parts tailored to demanding industrial applications.
Integrated Design, Tooling and Machining Capabilities
From product mold design to mechanical processing, our expert R&D and production teams manage the full lifecycle. Bost’s capacity includes steel‑plastic and plastic‑rubber composite solutions, precision molds and tight‑tolerance custom CNC machined parts for prototypes, small runs and high‑volume production with consistent quality control.
Applications and Industry Benefits
Our custom CNC machined parts serve sectors such as green energy, heavy machinery, chemical processing, medical devices and consumer electronics. Benefits include extended service life, reduced maintenance, lower weight and improved corrosion and wear performance, delivering measurable ROI for OEMs and integrators.
Quality Assurance and Customer Service
Bost follows strict quality protocols and offers material certification, dimensional inspection and on‑time delivery. Our customer‑centric approach ensures responsive technical support, rapid prototyping and flexible production scheduling to meet urgent or complex project requirements.

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
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.
