Bost Custom CNC Machined Parts
Product Overview
Bost custom CNC machined parts combine precise machining with advanced engineering plastics to deliver durable, lightweight, and high-performance components. Backed by Bosts R&D and production team, each part is tailored to meet specific dimensional, mechanical, and environmental requirements.
Key Features
- High precision: Tight tolerances and consistent finishes for parts that fit and perform reliably.
- Superior material options: Anti-scratch, ultra abrasion resistant, corrosion resistant, high temperature transparent, flame retardant, and enhanced toughness materials available.
- Functional modifications: Options for conductive, thermal, or wear-reduced formulations to match application needs.
- Fast prototyping to production: Quick turn prototypes and scalable volume manufacturing with strong quality control.
- Excellent machining stability: Sheets, rods, and molded blanks processed with professional CNC equipment to ensure repeatability.
Benefits for Your Project
Bost parts reduce weight while improving lifespan and reliability. The right plastic choice often replaces heavier metal parts without sacrificing strength. Corrosion and wear resistant plastics lower maintenance costs and extend service intervals. Clear communication, engineering support, and thorough testing ensure parts meet your specifications the first time.

FAQ
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.
If you have any other questions, please write email to us or call us , we will reply you as soon as possible.

Machined parts-CNC complex and precision plastic parts
Machined parts refer to components manufactured through subtractive manufacturing processes, where material is removed from a workpiece using cutting tools. This process is ideal for precision components with complex geometries that require high accuracy.

Insert molding solutions for plastic mould manufacturer
Insert molding is an injection molding process where pre-fabricated components, such as metal inserts, electronic parts, or other plastic elements, are placed into the mold cavity before molten plastic is injected around them. This bonds the insert with the plastic, creating a single, integrated part.

Custom Overmolding mould-BOST rubber and plastic supplier
Over molding is an advanced injection molding process that involves molding a second material over a pre-formed substrate, typically called the "carrier" or "base" part. This technique bonds two or more materials together, creating a single, multi-component product with enhanced functionality and aesthetics.
