2021 10 06 There are many small batches of prototype machining methods, such as CNC machining, simple molds made of silicone, and 3D printing. Look at the needs of customers. For CNC small batch prototype machining, we must first choose a suitable CNC prototype machining factory. There are many professional CNC machining factories in China, but they are not the same in scale. So in the face of many CNC prototyping factories, how do we choose?

VMT 2026 08 31 Aluminum CNC machining parts price is mainly determined by material, programming and setup, machining time, geometry, tolerance, quantity, tooling, surface finishing, inspection, and packaging. Simple turned or milled parts generally cost less, while complex, thin-wall, tight-tolerance, or multi-axis aluminum parts require more manufacturing control and therefore cost more.

VMT 2021 06 22 After sandblasting and oxidation of aluminum machining processing parts, trachoma and holes will appear on the surface, which will seriously affect the surface texture of the product. This is a frequent problem in the industry, which has a great impact on customers, and also seriously affects customers' brands and delivery dates!

VMT 2026 09 04 Sheet metal punching vs stamping are two important processes in sheet metal fabrication. Metal punching uses a punch machine to create holes or cutouts in thin metal sheets, while metal sheet stamping combines multiple operations, including punching, blanking, embossing, bending, flanging, and coining, to shape sheet metal into 3D components. It seems that these two terms are very easy to identify, however, they could be different from each other from many details. However, choosing the right one from metal punching vs stamping requires careful evaluation of design complexity, material suitability, production volume, tooling and piece costs, lead time, and process limitations, etc. Otherwise, it could lead to budget overruns, production bottlenecks, and compromised part quality if the wrong one is selected.

VMT 2026 09 02 Finishing processes can make the surface of CNC machined parts smooth and mirror-like! Electropolishing and mechanical polishing are precisely the two mainstream processes, each with its own pros and cons. Imagine this situation: after spending time and money on CNC machining services for your custom products, you choose an inappropriate process during the post-processing stage (when choosing between electropolishing and mechanical polishing). This could lead to surface roughness exceeding specification requirements, passivity failure, or unexpected secondary machining overhead—how frustrating that would be.
