Custom Plastic Injection Molding by Bost — Advanced Engineering Plastics

Custom Plastic Injection Molding Solutions from Bost

Overview

Bost is a professional, innovative high-tech manufacturer specializing in engineering plastics research, development, production and sales. Our custom plastic injection molding services deliver high-precision parts from modified engineering materials, including ultra-high anti-scar, super corrosion resistance, super fatigue durability, ultra abrasion-resistant and high-temperature transparent grades.

Materials & Capabilities

We modify ordinary engineering plastics to enhance toughening, flame retardancy, impact absorption, conductivity and thermal properties. Bost’s experienced R&D and production teams design molds, perform mechanical processing, and integrate complex steel-plastic and plastic-rubber combinations to meet demanding specifications for sheet, rod and molded components.

Performance Benefits

Choosing Bost for custom plastic injection molding guarantees parts that withstand extreme wear, temperature, chemical exposure and repetitive stress. Our material innovations reduce scarring, improve fatigue life, and provide targeted electrical or thermal conductivity — delivering longer product life, lower maintenance and superior reliability.

Industries & Applications

Our engineered materials and molding expertise serve electronics, automotive, energy, medical, industrial machinery and consumer products. Typical applications include high-temperature transparent components, flame-retardant housings, abrasion-resistant wear parts, conductive thermal interfaces and multi-material assemblies combining plastic, steel and rubber.

Why Choose Bost

Bost combines high production capacity with advanced mold design, strict quality control and customer-focused service. From prototype to volume production, we provide fast iteration, consistent tolerances and scalable manufacturing. Partner with Bost to transform your product ideas into durable, high-performance molded parts.

FAQ:

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.

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.
