High-Quality High Pressure Die Casting Built
Custom Aluminum Die Casting
Guangdong Kingrun Technology Co.Ltd., has been providing many die casting services to our customers for over 15 years in South of China. Kingrun is a professional die casting supplier of everything from die casting tooling to supplying finished die casting parts.
Kingrun uses a manufacturing process called High Pressure Die Casting (HPDC) to make aluminum die-cast parts.
We inject molten diecasting metal alloy with high pressure using a die casting machine into a steel die casting mold to make produce aluminum parts. The high pressure die casting process retains a durable strength at very high temperatures, requiring the use of cold chamber machines-a capability that Kingrun proudly offers to all our clients. Kingrun’s die casting dies can be simple or complex, having moveable slides, cores, or other sections depending on the complexity of the casting. Our aluminum die casting machines have capacities that range from 280 to 850 tons.
Kingrun Castings‘team will assist you with die cast tooling design including uniform walls,draft, fillets and radii, parting line and slides,machining allowance, tool making, die cast production and finish the surface of many kinds of die cast aluminum parts.
Benefits of Kingrun's High-Pressure Die Casting
As the most widely used non-ferrous metal globally, aluminum alloys have become the preferred choice for modern manufacturing due to their superior performance. Kingrun leverages its technological advantages in precision aluminum alloy die casting to provide global customers with high-strength, lightweight core component solutions. Aluminum die cast parts have more surface finishing options and can withstand higher operating temperatures than other non-ferrous materials. Aluminum die cast parts are corrosion resistant, highly conductive, have a good stiffness and strength-to-weight ratio. The precision die casting process is based on rapid production that allows a high volume of die casting parts to be produced very quickly and more cost-effectively than alternative casting processes. Kingrun is committed to technological innovation, ensuring that every precision die-cast aluminum product meets industry-leading quality standards, helping your projects achieve the perfect balance between lightweight and durability. characteristics and benefits of Aluminum Die Castings include:
● Lightweight and Durable
● High dimensional stability
● Good Stiffness and Strength-to-Weight Ratio
● Good corrosion resistance
● High thermal and electrical conductivity
● Fully Recyclable and Reusable in Production
What We Cast
Alloy selection should consider strength, ductility, castability, fluidity, corrosion resistance, thermal conductivity, pressure tightness, wear, machining, finishing, and cost. Published property values vary by test method and condition, so final requirements should be confirmed against the applicable material specification.
Clients can choose from a wide range of alloys for their aluminum die cast components that can differ in weight from 0.5kgs to 5.5 kgs. The types of die casting materials we use:
✓A360
✓A380
✓A383
✓ADC12
✓A413
✓A356
✓ENAC43400
✓ENAC46000
✓ENAC443000
Kingrun provides custom aluminum die casting services for low-volume and high-volume housings, brackets, base and covers, enclosures, heatsinks, heat-management components, and structural parts.

Kingrun's FSW + Die Casting Advantage
Advanced FSW Technology with High level Leak Testing
Kingrun combines aluminum die casting with Friction Stir Welding (FSW) to deliver integrated manufacturing solutions for components requiring reliable sealing and high joint integrity. FSW is particularly suitable for applications such as liquid cooling systems, inverter housings, motor housings, and other components requiring leak-tight performance. With dedicated leak-testing equipment and strict quality control procedures, Kingrun verifies the sealing performance of FSW components to help ensure consistent product quality and reliability. With 14 FSW machines, in house die casting, CNC machining, FSW, and helium leak testing under one roof, we provide customers with a streamlined manufacturing process, reduced supplier complexity, shorter lead times, and greater confidence in the quality of the final product.
Why FSW for Your Die Cast Parts?
FSW is an advanced solid-state welding technology that joins aluminum components without melting the base material. Compared with conventional fusion welding, FSW offers significant advantages for aluminum die-cast components, particularly those requiring reliable sealing and precision assembly.
1. Reliable Sealing Performance
FSW creates high-integrity joints suitable for applications requiring airtight or liquid-tight sealing, including liquid cooling systems, inverter housings, motor housings, and other sealed enclosures. Kingrun's helium leak testing capabilities help verify sealing performance and ensure components meet specified leakage rate requirements.
2. Reduced Porosity Risk
As a solid-state welding process, FSW avoids the molten weld pool associated with conventional fusion welding, significantly reducing the risk of weld porosity caused by gas entrapment. With proper material selection and process control, FSW can produce dense, consistent weld joints with improved integrity.
3. Minimal Thermal Distortion
FSW operates below the melting point of the base material, reducing heat input and minimizing thermal distortion. This helps preserve dimensional accuracy, maintain critical tolerances, and reduce the need for post-weld rework.
4. High Joint Integrity
FSW produces strong, reliable joints with excellent mechanical properties when appropriate materials and welding parameters are selected. Its solid-state joining mechanism makes it suitable for components exposed to vibration, mechanical stress, and demanding operating conditions.
5. Consistent Quality for Mass Production
With automated FSW equipment and controlled welding parameters, Kingrun supports repeatable production and consistent joint quality. Our integrated manufacturing process enables effective quality control from casting and machining through welding, leak testing, and final assembly.
