Bost More than just a machining shop
The perfect blend of material expertise and exceptional manufacturing processes
Our services extend far beyond simple machining. As a manufacturer specializing in high-performance engineering plastics with outstanding properties and precision machining capabilities (tolerance ±0.02 mm), Bost optimizes your bill of materials and production strategy from the outset, saving you time, reducing costs, and streamlining processes.
Our expertise also encompasses modifying engineering plastic sheets, rods, and molds for toughening, flame retardancy, absorptive properties, and thermal conductivity.
Material Expert Guidance
We don't just cut plastics—we are material experts. Our engineers recommend the optimal material grade (PEEK, PEI, or POM) based on your specific application requirements, considering temperature, chemical corrosion, load demands, and cost targets.
Free DFM Analysis - Reduce Costs Before Production
Free DFM analysis identifies cost-saving opportunities before manufacturing. Our clients typically achieve 15-30% unit cost savings through material optimization, tolerance adjustments, and process selection.
Zero Middlemen - Factory-Direct Pricing
Zero middleman markups = 20-40% cost savings. Our integrated supply chain controls every step from raw material inspection to finished CNC parts, ensuring quality and speed.
From Prototype to Production Scale
Start with 1 prototype and scale up to over 100,000 pieces. We seamlessly transition from CNC machining (small batches) to injection molding (large volumes) without changing suppliers or compromising quality.

Precision Injection Molding in Medical & Automotive: Mastering Material Selection and Tolerance Control
In the fields of medical devices and new energy vehicles (EVs), product lightweighting, biocompatibility, and extremely narrow tolerances (+/- 0.02mm) in harsh environments have become non - negotiable hard indicators. As high - specification precision injection molding gradually replaces traditional metal processing, how to perfectly handle special engineering plastics such as PEEK, PPS, or 50% high - glass - fiber composites has become the core dividing line that sets manufacturing enterprises apart.
This article delves deep into the engineering truths behind high - value - added precision injection molding projects, pointing out that "the machining accuracy of molds is only the foundation, and mastering the thermodynamic behavior of materials is the key." The article unfolds around the following four core dimensions:
Overcoming anisotropic shrinkage: Analyze the physical properties of materials such as glass fibers during the injection molding process and provide engineering ideas to solve the serious warping of slender components.
Processing barriers of special plastics: In response to the high - temperature crystallization requirements of medical - grade PEEK and the mold wear pain points of automotive - grade PPS + GF, propose customized equipment and mold steel solutions.
Data - driven scientific injection molding (Scientific Molding): Abandon traditional empiricism and demonstrate how to create a "zero - defect" mass - production system through cavity pressure monitoring and segmented control technology.
Pre - mold flow analysis (Moldflow): Emphasize the necessity of using CAE simulation technology to accurately predict and eliminate weld lines and air pockets before "starting to make the mold".
