VMT 2026 06 06 Hardcoat anodizing (MIL-A-8625 Type III) is the industry-recognized standard. It transforms the aluminum alloy surface into a hard, low-friction protective coating. To succeed, you need to master three critical variables: the 50/50 growth rule, pitch diameter compensation, and thread root radius design to prevent edge flaking. In this article, we will break down to overcome the wear issue, followed by a practical case study from our factory shop floor.

VMT 2026 06 03 As a global China CNC machining parts manufacturer industry, China occupies an important position in this industry. In China, from rapid prototyping, to small batch manufacturing of CNC parts, to the production and surface treatment of batch processed parts, a scale has been formed. China's CNC machining parts have the core advantages of fast delivery, high quality and low price in terms of materials, technology, machinery, processing, etc., so they have attracted buyers from all over the world. This article summarizes how to choose a supplier suitable for domestic CNC machining parts.

VMT 2026 06 02 From the appearance, both processes can give the metal surface a deep black color. However, for the inner wall of the lens barrel, which has strict requirements for light reflectance, the actual performance of the two differs in light absorption performance, dimensional change, and wear resistance, and they have different adaptability for lens barrels of different materials. In this guide, we will analyze the differences between the application of black anodizing and black oxide on the inner wall of the lens barrel, and help you determine which surface treatment process is best suited for your next optical project.

VMT 2026 06 01 While many non-medical suppliers are capable of machining titanium alloys or PEEK, they often lack an understanding of medical-grade contamination control standards. Improper control of cutting heat or incorrect selection of cutting fluids can easily lead to material degradation or harmful residue contamination, causing the parts to fail biocompatibility testing. Furthermore, blindly pursuing high precision can skyrocket scrap rates and cause costs to spiral out of control; inexperienced suppliers struggle to find the balance between meeting medical tolerances and achieving cost-efficiency in mass production. Therefore, you need a reliable list of CNC medical parts manufacturers.
