OEM Aluminum Die Casting heatsink for 5G Base Station
Project Overview:
ADC12 aluminum housing produced on a 1650T die-casting machine for a communications structural component.
Process:
Controlled melt at 640°±20°, strict ban on recycled secondary materials, composition verification, and first-article confirmation. Surface checks focused on fill integrity and ejector-pin accuracy (0–0.2 mm tolerance).
Result:
Achieved stable casting quality with full fill, clean surfaces, and dimensional consistency ready for downstream CNC machining.
Router housing
Router shells are usually made of ABS engineering plastics, aluminum alloy (6063) or flame-retardant PC/ABS alloy materials, and are processed by injection molding, die-casting or sheet metal stamping
Communication board
Communication baseboards are usually made of FR-4 epoxy resin substrates, aluminum substrates or ceramic substrates and processed by PCB etching, drilling and immersion gold technology or DCB technology.

Communications Industry FAQ
Find answers to the most common questions about our telecom component manufacturing capabilities.
A. We produce RF housings, antenna brackets, filter cavities, heat sinks, enclosures, and other precision metal parts for 4G/5G communication equipment.
A. Our tolerance performance is tailored to the manufacturing process, and here are the specific achievable ranges:
- CNC machining: It can stably control the tolerance within ±0.003–0.008 mm. This precision is fully capable of meeting the production needs of key RF and communication parts, avoiding problems such as poor assembly or signal interference caused by size errors.
- Die casting: As a high-efficiency forming process, its tolerance is generally ±0.02–0.1 mm. It is mainly used to produce large structural parts of communication equipment, which can well balance production efficiency and the basic dimensional requirements of parts.
If you have special precision needs, we can combine the two processes to adjust the tolerance to the required level.
3. Yes, we provide fast prototypes based on your 2D/3D files through CNC machining, deburring and cleaning, secondary precision machining, surface finishing, and proper protection before shipping.
A:Yes. We offer free DFM checks to ensure proper heat dissipation, structural stability, and manufacturability for communication components.
A: Aluminum alloys (6061, 6063, A380, ADC12), brass, stainless steel, and other RF-friendly metals depending on weight, strength, and thermal requirements.
