High-Performance Plastic Spur Gears by Bost

Plastic Spur Gears by Bost — Precision Engineering Plastics

Overview

Bost specializes in the research, development and manufacture of high-performance plastic spur gears designed for modern mechanical systems. Our gears deliver quieter operation, reduced weight and improved chemical and wear resistance compared with metal counterparts. Built from modified engineering plastics with enhanced toughening, flame retardancy and thermal conductivity where needed, Bost's plastic spur gears meet demanding industrial standards while supporting green, energy-efficient design.

Materials & Performance

We produce plastic spur gears using a range of specialty materials—modified PA (nylon), POM, UHMWPE, high-temperature transparent polymers and conductive or flame-retardant blends. Each material is tailored to offer ultra abrasion resistance, anti-scar surfaces, superior fatigue life and excellent corrosion resistance. These material choices reduce noise, eliminate lubrication concerns in some applications and extend service intervals for maintenance-sensitive assemblies.

Customization & Precision Manufacturing

Bost's experienced R&D and tooling teams provide full-service gear customization: mold design, precision machining, and multi-material integration (steel-plastic, plastic-rubber combinations). We deliver tight tolerances, optimized tooth profiles and surface finishes to ensure smooth power transmission and long-term reliability for every batch of plastic spur gears.

Applications & Benefits

Our plastic spur gears are ideal for automotive components, consumer appliances, medical devices, packaging equipment and industrial automation. Benefits include lower inertia for faster response, corrosion resistance in harsh environments, reduced wear on mating parts and cost-effective mass production. Bost gears also support noise-sensitive applications and designs where weight reduction is a priority.

Quality, Sustainability & Support

Bost maintains rigorous quality control and sustainable manufacturing practices. We emphasize energy-efficient production, recyclable material options and comprehensive testing to meet customer specifications.
