Custom Plastic Injection Molding Services by Bost
Why Bost for custom plastic injection molding
Bost is a professional, innovative high‑tech green energy engineering plastics manufacturer focused on R&D, production, and sales. We specialize in custom plastic injection molding of special engineering plastics that require exceptional anti‑scar, super corrosion resistance, fatigue durability, ultra abrasion resistance, and high‑temperature transparency. Our team ensures product quality and customer satisfaction through rigorous process control and material expertise.
Materials & special properties
We work with a broad range of modified engineering plastics and tailor properties including toughening, flame retardancy, impact absorption, and thermal/electrical conductivity. Bost enhances sheets, rods, and molded components to meet demanding requirements—combining polymers with additives or hybrid steel‑plastic and plastic‑rubber assemblies to achieve superior performance in harsh environments.
Precision mold design & manufacturing
Bost’s experienced R&D and tooling teams provide end‑to‑end solutions: part design, mold engineering, CNC machining, and injection molding production. Our strengths in mold design and manufacturing translate to tight tolerances, consistent cycle times, and optimal surface finishes—critical for high‑precision custom plastic injection molding projects across industries.
Scalable production & quality assurance
From prototypes to high‑volume runs, Bost offers scalable production with robust quality systems. We apply thorough mechanical processing, dimensional inspection, and material testing to ensure each molded part meets specification. Our production capacity and technical expertise support complex assemblies, multi‑material components, and post‑processing requirements.
Applications & customer support
Bost serves automotive, renewable energy, medical device, industrial machinery, and consumer electronics markets. Our customer‑centric approach includes application consulting, material selection, and after‑sales support—helping you leverage custom plastic injection molding to reduce cost, improve performance, and accelerate time‑to‑market. Contact Bost to discuss your project and get a tailored solution.

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.
