Recently, Taizhou Xiejin Precision Machinery Co., Ltd. completed batch delivery of customized aluminum alloy power housings. The products are used in unmanned vehicles, servo actuators and power units of intelligent equipment. Adopting a full set of processes including precision aluminum alloy forming, CNC finishing and black hard anodizing, we offer one-stop support to help equipment manufacturers address common challenges in aluminum housing development, such as long lead times, insufficient heat dissipation and unsatisfactory sealing performance.
Industry Difficulties
Manufacturers supplying unmanned equipment, intelligent servo systems and customized intelligent engineering generally face three major challenges in custom aluminum alloy housing fabrication:
High mold investment and long sampling cycles. Traditional die-casting molds require substantial upfront costs, and many manufacturers decline small-batch orders. Under the multi-outsourcing model, casting, machining and surface treatment are handled by separate vendors. Sample delivery often takes more than 30 days, delaying prototype testing and project bidding schedules.
Balancing heat dissipation and structural strength is challenging. Housings for outdoor equipment need lightweight design while quickly dissipating heat generated by motors and driver boards. Conventional aluminum castings are prone to defects like pores and sand holes. Leakage risks exist at high-pressure sealing sections and waterproof threads, and corrosion may occur under prolonged outdoor operating conditions.
Multi-process and multi-vendor coordination complicates quality control. If casting, CNC machining and anodizing are subcontracted to different suppliers, liability is hard to define when dimensional deviations or surface defects arise. For smart park unmanned equipment and intelligent engineering projects in particular, delivery stability directly affects project acceptance.
Product Advantages
The delivered servo / power actuator aluminum alloy housings adopt integrally formed aluminum blanks. Five-axis CNC is applied for precision inner cavity machining. Flange mounting surfaces and threaded holes are finished in a single operation for excellent inner cavity smoothness. Heat dissipation ribs on the housing outer wall boost heat exchange efficiency. The surface undergoes black hard anodizing treatment for wear and corrosion resistance, suited to humid outdoor environments with wide temperature fluctuations.
Customization available based on drawings or samples. We undertake small-batch prototype sampling and stable mass production;
All processes completed in-house: forming, CNC machining, tapping and anodizing. Cross-factory handovers are reduced, shortening sampling cycles to 10–15 days;
Strict dimensional inspection is implemented. Flange mounting holes, external pipeline threads and sealing grooves are integrally formed to cut customers’ subsequent secondary assembly and processing costs;
Lightweight material design, roughly 60% lighter than cast iron. Suitable for unmanned vehicle actuators, security power units and motor housings for intelligent engineering projects.
Industry Value
As smart park, customized intelligent and low-speed unmanned equipment projects keep advancing in Jiangsu Province, market demand for non-standard custom aluminum alloy housings continues to rise. Many weak-current engineering and system integration companies previously could only buy standard housings, while non-standard structural parts came with high procurement costs.
As a local manufacturer of aluminum die castings and aluminum drawn precision castings, Taizhou Xiejin Precision covers the full production chain from blank forming and precision machining to surface treatment. We provide one-stop aluminum alloy housing solutions for engineering integrators and equipment R&D enterprises in the Yangtze River Delta, lowering the hardware development threshold for non-standard equipment and supporting the rollout of local intelligent projects.
