Custom CNC Machined Aluminum & Stainless Steel Blocks from China: A B2B Sourcing Guide
Solid metal blocks sit at the core of a lot of equipment: manifold and port blocks, sensor and spacer blocks, clamp blocks, locating blocks in fixtures and automation cells. Because they are machined from solid stock, the drawing decides almost everything about cost, lead time and how well the part fits. This guide covers what…

ISO 2768 General Tolerances for CNC Machined Plates & Brackets: f, m or c?
Many drawings carry one short note in the title block, such as “ISO 2768-m”, and leave every other dimension untoleranced. That note is doing a lot of work: it sets the tolerance for every length, radius and angle that has no tolerance of its own. This guide explains what each ISO 2768 class allows, which…

Anodizing Aluminum Plates & Brackets: What Changes Size
A mounting plate can pass every dimension at final inspection and still come back from anodizing with dowel pins that won’t go in and screws that won’t start. Anodizing is not a coat of paint sitting on top of the part. It converts the aluminum surface into oxide, and part of that oxide grows outward,…

DFM Checklist for CNC Machined Mounting Plates & Brackets
Most of the questions we raise during drawing review at VANTECH CNC come back to the same few details: a sharp inside corner, a tight tolerance on a face that doesn’t mate with anything, or a feature that forces one more setup. None of them are mistakes in the design intent. They are just details…

CNC Machined Aluminum Enclosures and Heat Sinks: Thin-Wall Parts for OEMs
Aluminum enclosures and heat sinks sit at the heart of many machines: they protect electronics, carry heat away from power components and give the product its finished look. When the design calls for thin walls, tight pockets or custom fin geometry, CNC machining is often the fastest and most reliable way to make them, from…

Custom CNC Machined Housings and Covers: What to Specify Before Ordering
Custom CNC machined housings and covers protect the most sensitive parts of your equipment: electronics, sensors, motors and optics. They also have to seal, mount, dissipate heat and look good. That is why a housing RFQ that only says “machine per drawing” often leads to back-and-forth questions, quotes that don’t compare, or parts that pass…
