Structural Integrity at Scale: High-Pressure Die Casting Excellence
The quality of an electric motor is defined by the housing that contains it. At HENTACH, formerly known as Hengtai Motor, our 500-Ton Die Casting Capabilities represent the pinnacle of our manufacturing infrastructure. For 30 years, we have maintained a dedicated casting department within our 9,000-square-meter facility to ensure we have total control over the structural backbone of our products. While other manufacturers outsource their housings to third-party foundries—risking porosity and dimensional drift—HENTACH (Hengtai) manages the entire process from molten alloy to finished part. Since 1995, we have utilized high-pressure die casting to produce motor components that are lighter, stronger, and more thermally efficient than standard sand-cast or stamped-steel alternatives.
Our 500-ton machines inject molten aluminum or magnesium into precision-engineered steel molds at incredible speeds. This high-pressure environment eliminates internal air pockets (porosity), which is the primary cause of structural failure in lower-quality castings. By producing a dense, unified metal structure, we ensure that our motor housings can withstand the extreme mechanical stresses of heavy-duty use. This structural perfection is the foundation of our 50,000-mile durability benchmark. A HENTACH housing doesn't just hold the motor; it acts as a high-performance heat sink and a vibration dampener, ensuring that the internal magnets and windings remain in a pristine operating environment. Our electromechanical innovation is rooted in the belief that "better parts make better motors."
Furthermore, our die-casting capabilities are integrated with our precision CNC workshop and our proprietary Micro-Arc Oxidation (MAO) surface treatment facility. Once a housing is cast, it is machined to tolerances of ±0.005mm and then treated to create a ceramic-grade surface hardness. This vertical integration allows us to provide B2B partners with a level of quality consistency that is unmatched in the industry. Whether we are casting complex thin-walled shells for lightweight e-bikes or reinforced hubs for industrial cargo trikes, our ISO 9001 certified process ensures that every part meets the exact metallurgical and dimensional standards required for professional-grade performance. HENTACH is more than a motor manufacturer; we are a center of excellence for high-pressure metal forming.

Applications for High-Pressure Die Cast Parts
Our 500-ton die-casting capabilities are the foundation for Electric Vehicle Powertrain Enclosures. This includes the outer shells of our hub motors, the housings for mid-drive systems, and the structural frames for high-power controllers. Beyond our own motors, we provide contract casting for High-End Consumer Electronics and industrial robotics, where lightweight magnesium parts are required for thermal management and structural rigidity. The ability to cast complex, integrated cooling fins makes our housings the primary choice for liquid-cooled or air-cooled motorcycle motors. Our 30-year legacy of "Hengtai" excellence means we can solve the most difficult metallurgical challenges for our global B2B partners.
- Hub Motor Hubs and End-Caps for e-bikes and motorcycles.
- Mid-Drive Gearboxes for high-performance e-MTBs.
- Controller and Inverter Heat-Sink Enclosures.
- Lightweight Magnesium Frames for handheld medical devices.
- Industrial Pump and Actuator housings for harsh environments.
The Advantage of Vertical Structural Control
The advantage of HENTACH's in-house casting is Predictable Quality. When you outsource casting, you inherit the foundry's defects. By managing our own 500-ton machines, we control the alloy temperature, the injection speed, and the cooling cycle to a fraction of a second. This level of electromechanical innovation is why our motors are proven to reach 50,000 miles of operation. Our housings do not warp, crack, or leak, even after years of thermal cycling. This is a direct result of our 30-year legacy as a professional-grade manufacturer. We don't just build a shell; we build a precision-engineered environment for your motor's internal components.
Furthermore, our Rapid Tooling and Design capabilities allow us to assist B2B partners in optimizing their designs for the die-casting process. We use advanced flow simulation software to ensure that the molten metal reaches every corner of the mold, preventing the "cold shuts" that weaken parts. Our ISO 9001 certified facility includes a full metallurgical lab where we test the hardness and tensile strength of every batch of metal. Partnering with HENTACH for die casting gives you the assurance that your product's structural integrity is backed by three decades of manufacturing wisdom. We provide the scale, the speed, and the structural excellence that modern industrial projects require. We are the foundation of your engineering success.
