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.
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.
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

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.

Nylon Plastic Worm Gear custom for transmassion device
Nylon plastic gears have emerged as a preferred choice in modern manufacturing due to nylon's exceptional material properties. Nylon, a type of synthetic thermoplastic polymer, boasts high strength, excellent abrasion resistance, and low friction coefficients. It also exhibits good chemical resistance to various solvents, fuels, and lubricants, while maintaining dimensional stability across a wide temperature range. Additionally, nylon's self-lubricating nature reduces the need for external lubricants, simplifying maintenance.

PEEK plastic Spur gear-high strength and harder
PEEK (Polyetheretherketone) is a high-performance thermoplastic known for its exceptional mechanical, chemical, and thermal properties. PEEK plastic gears leverage these characteristics to offer significant advantages over traditional materials.
