Die-Cast Motor Housing Production

Structural Excellence: The Art of High-Pressure Die Casting
The motor housing is the unsung hero of the electromechanical world. It must protect internal windings, dissipate intense heat, align precision bearings, and withstand the mechanical stresses of the vehicle—all while remaining as light as possible. At HENTACH, Die-Cast Motor Housing Production is a core competency that has defined our brand for 30 years. Formerly known as Hengtai Motor, we integrated high-pressure die casting directly into our 9,000sqm manufacturing campus to ensure we never had to compromise on structural quality. Today, we operate a suite of 500-ton die-casting machines that produce complex, thin-walled housings from premium aluminum and magnesium alloys. This internal capability is the reason our motors are among the few in the industry to consistently exceed the 50,000-mile durability mark.
Our die-casting process is a high-tech operation governed by ISO 9001 standards. Using molten ADC12 or A380 aluminum, we inject the metal into precision-engineered steel molds at incredible speeds and pressures. This results in a housing that is almost entirely free of internal porosity—the "bubbles" that can cause traditional castings to crack under the thermal expansion of a motor. Once cast, the housings move to our precision CNC workshop, where we machine bearing seats and mounting faces to a tolerance of ±0.005mm. This "Cast-to-CNC" workflow is vital because it ensures that the magnetic air gap between the rotor and stator is perfectly uniform, which is the secret to the high efficiency and silent operation of HENTACH motors. Our 30-year legacy of electromechanical innovation means we design our housings with integrated heat-dissipation fins and cable-routing paths that are cast directly into the metal, reducing assembly time and cost for our partners.
Furthermore, our production facility is optimized for the advanced surface finishes required by the modern market. Every housing we produce can be treated with our proprietary Micro-Arc Oxidation (MAO) process, transforming the surface into a ceramic-grade layer of protection. This is particularly important for magnesium housings, which are 33% lighter than aluminum but require specialized protection against corrosion. Since 1995, we have provided ODM and OEM housing solutions for everything from 250W city-bike motors to 8000W motorcycle drives. When you choose HENTACH for motor housing production, you are leveraging an industrial-scale manufacturer that understands the physics of motors as well as the chemistry of metals. We provide the professional-grade structural backbone for the world’s most reliable electric drives.

Applications for Precision Motor Enclosures
Our die-cast housings are used globally as the structural foundation for Electric Vehicle Powertrains. This includes the outer shells of hub motors, the enclosures for mid-drive units, and the heat-sinking frames for high-power motor controllers. Beyond transportation, these housings are essential for Industrial Automation Equipment, where they protect robotic joints and conveyor drives from the rigors of 24/7 warehouse operation. The lightweight nature of our magnesium castings makes them the primary choice for professional power tools and handheld equipment where operator fatigue must be minimized without sacrificing the tool's durability.

The Advantage of Vertical Integration in Casting
The primary advantage of HENTACH housing production is Accountability. Most motor manufacturers buy their housings from third-party foundries, which often leads to dimensional drifting and material inconsistencies. By owning the 500-ton die-casting process within our own facility, we control the "DNA" of the motor. We can adjust the alloy chemistry to improve thermal dissipation or increase the clamping pressure to ensure a denser part. This level of control is why our motors have been able to surpass 50,000 miles of service; the housing simply does not warp or fatigue. Our 30-year history of electromechanical innovation means we know exactly where a housing is likely to fail, and we reinforce those areas during the mold design phase.
Moreover, our Rapid Tooling and Prototyping capabilities allow our B2B partners to move from concept to mass production faster than with any other supplier. We can produce initial CNC-machined samples for testing and then transition to high-volume die casting once the design is finalized. Our ISO 9001 certified quality control includes X-ray inspection of castings to verify internal integrity and CMM checks for every critical dimension. Partnering with HENTACH means you are working with a professional-grade manufacturer that views the housing not as a simple box, but as a precision-engineered cooling and support system. We provide the structural excellence that allows your brand to lead the market.
