Custom Precision CNC Machining Parts Details
Custom Turn-Mill Heat Sink Flange
This circular flange-type heat sink mounting base (also known as motor cooling flange or optoelectronic module base) is a non-standard OEM component widely used in automation servo motors, industrial vision systems, and precision optical modules – where effective thermal management and accurate component positioning are mission-critical.
Product Highlights
| Feature | Function & Specification |
| Radial cooling fins | Maximise heat dissipation for reliable thermal management |
| Flange mounting face with threaded holes | Ensures flatness and coaxiality – coaxiality ≤ 0.02mm |
| Centre locating platform | Accurately mounts motors, sensors, or light sources |
| Side windows | Serve as cable ducts or airflow paths |
| Surface finish | As-machined or anodised (black hard anodising available) – Ra 0.1~3.2 or as per client’s needs |
| Material | 6061/6063 aluminium (stainless steel alternatives available) |
| Dimensional tolerance | ±0.01mm ~ ±0.001mm, or as per client’s specific requirements |
We offer custom manufacturing for identical or similar heat sink flanges and precision structural parts according to your drawings – whether you need minor modifications or a completely new design, we are ready to support you.
This Part Is Made In-House – From Start to Finish
This heat sink flange is fully produced in-house – from DFM analysis and precision turn-mill machining (holding tolerances from ±0.01mm to ±0.001mm) to anodising and final CMM inspection – exactly the end-to-end service we provide for all your parts. Our capabilities are not just promises; they are processes already proven on this very component.

Quality Assurance – ISO 9001:2015 Certified
Quality is built into every step of our process – from the first design review to the final inspection of parts like the heat sink flange:
Free DFM Analysis – We don't just machine your parts; we optimize them. Our free Design for Manufacturability (DFM) analysis identifies potential manufacturing issues and cost-saving opportunities before production starts, ensuring smooth production and consistent quality.
Strict Inspection – We use CMM (Coordinate Measuring Machines), optical measurement systems, surface roughness testers, and First Article Inspection (FAI) protocols to ensure every part meets your exact specifications. In-process inspections are conducted at every critical stage – precisely how we verify dimensional tolerances (down to ±0.001mm), coaxiality (≤ 0.02mm), and surface roughness (Ra ≤ 1.6μm) on every heat sink flange – with the flexibility to adjust tolerances according to your specific needs.
Supply Chain Quality – We work only with approved, certified material suppliers, and conduct incoming inspection on all raw materials before they enter our production floor.
