Bost Custom Over Molding — Advanced Engineering Plastics

Bost Custom Over Molding Solutions for High-Performance Products

Precision R&D and Material Innovation

Bost combines deep materials science with decades of engineering plastics expertise to deliver custom over molding solutions that meet stringent performance and environmental standards. Our dedicated modification R&D team enhances toughness, flame retardancy, thermal conductivity, and anti-scar properties in polymers to tailor materials for each overmolding application.

Specialized Material Properties

We produce and supply a wide range of special engineering plastics — ultra abrasion resistant, super corrosion resistant, fatigue durable, high-temperature transparent, and conductive grades. These materials enable custom over molding assemblies that require long service life, aesthetic integrity, and reliable mechanical performance under harsh conditions.

Integrated Design-to-Manufacture Capability

Bost offers end-to-end services including mold design, mold manufacturing, mechanical processing, and final assembly. Our experience in steel-plastic and plastic-rubber combinations ensures seamless integration of overmolded components into complex products, reducing development cycles and improving manufacturability.

Applications and Customer Benefits

Custom over molding from Bost is ideal for automotive connectors, consumer electronics, industrial equipment, medical devices, and green energy components. Benefits include improved sealing, ergonomic surfaces, vibration isolation, electrical insulation or conductivity as required, and enhanced aesthetic finishes.

FAQ:

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.

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

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.
