Custom Insert Molding Solutions by Bost
Why Choose Bost for Custom Insert Molding
Bost is a professional and innovative high-tech green energy engineering plastics manufacturer specializing in R&D, production, and sales. We deliver custom insert molding solutions that combine precision plastics with metal or electronic inserts to create durable, high-performance components tailored to your specifications.
Advanced Materials & Proprietary Modifications
Our engineering plastics portfolio includes ultra-high anti-scar, super corrosion-resistant, superior fatigue-durable, and ultra abrasion-resistant formulations. We enhance toughness, flame retardancy, thermal conductivity, and conductivity through proprietary modification processes to meet demanding application requirements.
Precision Mold Design & Integrated Manufacturing
Bost’s expert R&D and production teams provide end-to-end services: product design, mold design and manufacturing, and mechanical processing. We specialize in complex steel-and-plastic and plastic-and-rubber combinations that require tight tolerances and integrated insert molding techniques for reliable, long-lasting assemblies.
Quality Control & Green Energy Commitment
Quality assurance is built into every stage — from raw material selection to final inspection. As a green-energy focused manufacturer, Bost emphasizes sustainable processes and energy-efficient production while maintaining strict performance standards for safety-critical and high-temperature applications.
Applications Across Industries
Our custom insert molding parts serve automotive, renewable energy, electrical, telecom, medical, industrial machinery, and consumer electronics markets. Typical components include threaded inserts, overmolded sensors, heat-resistant connectors, and hybrid steel-plastic structural parts.
Partner with Bost — From Prototype to Volume
Whether you need rapid prototyping, small-batch validation, or full-scale production, Bost provides responsive engineering support, fast tooling, and scalable manufacturing. Contact Bost to discuss your custom insert molding project and experience high-performance materials combined with precision manufacturing.

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
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.
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.
