Precision Aluminum & Magnesium Die Casting for Automotive, EV and Aerospace

Aluminum high-pressure die casting is the backbone of our production. We cast a wide range of structural and functional components in ADC12, A380, A356 and A360 alloys, balancing thermal conductivity, corrosion resistance and dimensional stability for demanding service environments. Our cold-chamber machines span 400T to 5000T, allowing us to serve everything from intricate thin-wall enclosures to large automotive structural parts in a single shot.

Every aluminum die casting program begins with mold-flow simulation. By modeling filling, solidification and cooling before tooling is built, we remove cold shuts, misruns and shrinkage porosity at the design stage rather than on the production line. Post-casting, in-house CNC machining centers hold critical mating surfaces to ±0.01 mm, and secondary operations such as anodizing, powder coating, shot blasting and impregnation are coordinated within the same facility.

Typical applications include automotive powertrain housings, EV battery trays and brackets, heat sinks, lighting housings and electronic enclosures. For customers who need verified material behavior, we publish engineering references on ADC12 properties and A356 structural integrity so design teams can specify with confidence.

Magnesium die casting delivers the ultimate weight reduction — roughly one-third lighter than aluminum at comparable stiffness — making it the material of choice for weight-critical automotive, aerospace and premium electronics components. KingShip casts AZ91D and AM60B magnesium alloys on dedicated hot- and cold-chamber machines, with minimum wall thickness down to 1.0 mm for thin-wall, complex geometries.

Magnesium’s high strength-to-weight ratio and excellent EMI/RFI shielding are valuable for electric-vehicle brackets, sensor housings, drone frames and handheld devices. We protect surface integrity with passivation and electroplating processes tuned for magnesium corrosion resistance, and we verify wall thickness and internal quality with real-time X-ray inspection before shipment.

Because magnesium casting demands strict process control, our engineers manage melt protection, injection velocity and die temperature closely to avoid oxidation and hot cracking. The outcome is a lightweight, dimensionally stable component that helps OEMs hit aggressive vehicle-mass and range targets without sacrificing structural performance.

Semi-solid rheocasting is our solution for parts that must combine low porosity, high ductility and heat-treatability. By forming the alloy in its semi-solid state — a slurry of solid globules suspended in liquid — rheocasting almost eliminates gas entrapment and shrinkage porosity that conventional high-pressure die casting cannot fully avoid.

The result is a casting that can be T5 or T6 heat treated, welded and mechanically worked, opening the door to structural safety components where flaw-free integrity is non-negotiable. KingShip operates a Yizumi semi-solid rheocasting system and validates microstructural uniformity with metallography and real-time X-ray comparison, so customers can qualify rheocast parts for crash-relevant and load-bearing applications.

Rheocasting is especially attractive for EV and aerospace structural nodes, suspension brackets and booms where fatigue life matters. By reducing porosity at the source, we shrink the inspection burden downstream and improve the predictability of every shipped lot.

Our 5000-ton cold-chamber die casting machine is built for the largest, thinnest-wall structural components in the automotive and EV industries. Large structural castings — such as battery tray side rails, shock towers, tunnel housings and crossmembers — consolidate what used to be dozens of stamped and welded stampings into a single, stiff, lightweight aluminum part.

Producing these parts demands more than tonnage. It requires precise shot control, thermal management of a very large die, and disciplined process windows to keep warpage and porosity in check across a meter-scale footprint. KingShip’s engineering team models the entire casting system, then validates first articles with CMM, X-ray and leak testing before ramp.

By integrating large structural casting with in-house CNC machining and finishing, we deliver a dimensionally complete assembly-ready component, not just a raw casting. This reduces customer inbound logistics, welding distortion risk and total program cost while improving vehicle stiffness and crash performance.

Casting is only half the story. KingShip’s in-house high-precision CNC workshop completes the component — drilling, threading, milling and boring the critical mating surfaces that the die casting process cannot reach. Our 3-axis, 4-axis and high-speed 5-axis machining centers hold tolerances up to ±0.01 mm on aluminum and magnesium parts.

Because machining sits next to casting, we eliminate the hand-off delays and quality disputes that come with outsourcing. Datums are consistent from cast to cut, first-article reports are generated on the same floor, and last-minute design tweaks flow straight back to the cell. We also perform value-added operations such as helical threading, boss facing and tight-tolerance bores for sealing surfaces.

For pressure-sealed components we add automated leak testing immediately after machining, so airtightness is confirmed before the part leaves the building. The net effect is a finished, inspection-ready component delivered from a single supplier.

Tooling quality defines everything that follows. KingShip operates an in-house tooling shop using advanced CAD/CAM, Pro/E, UG and Moldflow simulation to design and build dies that run longer and produce cleaner parts. Optimized gating and cooling systems reduce cycle time, minimize porosity and extend mold life beyond 100,000 shots.

Keeping tooling under our own roof means faster iteration: engineering changes, maintenance and refurbishment happen without third-party lead times. It also lets us protect proprietary gating know-how and keep it consistent across a product family. For low-volume bridge programs we offer bridge tooling that gets prototypes into your hands quickly before committing to a full production die.

A well-engineered die is the cheapest insurance against scrap, downtime and field failures. That is why KingShip treats tooling as a core competency, not a purchased commodity.
