POM CNC Machining Guide: Grades, Parameters, Stress Management, and 0.05mm Flatness Control
The core of POM (polyoxymethylene / acetal) CNC machining is controlling heat and stress: select the right POM-H or POM-C grade, use sharp tooling and a generous chip load so the tool cuts rather than rubs, and combine light workholding, symmetrical material removal, and a two-stage roughing – stress relief – finishing process to produce consistent high-precision parts. Cremage integrates these steps into a standard process route, holding POM flatness within 0.05mm and controlling it precisely to drawing requirements — a capability that non-specialist machine shops rarely match.

Injection molding is a high-growth business, supported by Yizumi all-electric servo injection molding machines and an in-house mold shop, covering everything from mold flow analysis and distortion prediction to volume production. The company is ISO9001:2016 certified and exports to developed markets including Germany and the United States.
Anti-Static Acrylic Sheet: Principles, Parameters, and Applications
Anti-static acrylic sheet controls surface resistance to prevent static buildup from damaging electronic components, making it a common protective material for semiconductor and electronics automation equipment. This article explains the principles behind anti-static acrylic, the key surface resistivity parameters that define each protection class, typical applications in ESD-safe guards and viewing windows, and what to check when specifying a sheet.
Custom Equipment Guard Process and Tolerance Requirements
Acrylic equipment guards are critical safety and dust-protection components on automation lines: they must let operators see the process inside while keeping out dust, splashes, and accidental contact. This article outlines the complete custom process from requirement confirmation to delivery, along with the key tolerance and material selection points that help equipment builders move from drawing to production efficiently.
Injection Mold Development Process Explained: From Design to Production
Injection molding solutions hinge on mold development. This article explains the complete process for an injection mold — requirement confirmation, mold design, steel selection, machining, mold trials, and mass production — along with the key quality control points at each stage, typical lead times, and how maintenance affects mold life.
What Is POM? Properties and Precision Machining of POM Plastic
POM (polyoxymethylene / acetal) is a highly crystalline engineering plastic with excellent wear resistance, fatigue resistance, and dimensional stability, widely used for precision parts such as gears, sliders, and servo structural components in automation equipment. This article covers the material properties of POM, the key points for machining it, and practical guidance on material selection.
Material Selection Guide and Risk Prevention for Acrylic Sheet in Industrial Applications
High-quality virgin acrylic sheet offers light transmission of at least 92%, more than 20 years of indoor weather resistance, a clear, colorless cut edge, stable thermoforming without bubbling, and no odor when cut. Recycled sheet, by contrast, yellows within six months, transmits less than 86% of light, shows a yellow or bluish cut edge, bubbles when heated, and gives off a pungent odor when cut. Checking three things — cut-edge color, thermoforming behavior, and cutting odor — is enough to tell them apart quickly.
