Die-Casting

Magnesium (hot & cold die casting)

Magnesium is the lightest of all casting materials and offers advantages over steel and some aluminum alloys in dimensional stability, impact resistance, and dent resistance. Modern high-purity magnesium alloys have better corrosion resistance than steel and some aluminum alloys.

We are a magnesium die casting company and have large and advanced cold chamber magnesium die-casting machine, specializing in magnesium die-castings. We also have hot-chamber magnesium die-casting machines for all product needs. And we are also an magnesium aluminum alloy die casting supplier. We can produce alloy for our customers’ desgin.

Zinc Die Casting

As a cost-effective solution, it is ideal for large-scale manufacturing, especially in zinc die casting. With its exceptional strength at room temperature, it ensures reliable performance in various zinc die casting products. Additionally, it features a surface that is easy to plate and paint, providing flexibility for different finishing options. As a leading choice for zinc die casting manufacturers, this material is widely used in zinc high pressure die casting and zinc pressure die casting, providing high-quality solutions for zinc die casting companies. We produce net-formed, no-flash components at low unit costs and minimal tooling investment.

Advanced Scojet Cold Chamber Die Casting

Cold chamber die casting is a better way when you want metals that melt only when in high temperatures. These metals are aluminum alloys, zinc alloys, brass, copper, etc. Cold chamber die casting consists an external furnace, and a ladle to pour the molten metal. The cold chamber die-casting can produce denser metal castings. Scojet is your trusted provider that offers you high-quality cold chamber die-casting service.

Cold Chamber Die Casting Advantages

Dimensional accuracy and stability

The process produces durable and dimensionally stable parts while maintaining tight tolerances and heat resistance.

High-speed production

The cold chamber process produces castings with complex shapes and tighter tolerances than many other mass production processes. Little or no machining is required, and thousands of identical castings can be produced before additional machining is needed.

Simplified Assembly

Cold chamber die castings provide integral fastening elements such as tabs and studs. Holes can be core drilled and sized for tapping drills or external threads can be cast.

Multiple Finishing Techniques

Cold chamber parts can be produced with a smooth or textured surface finish and can be easily plated or finished to tolerances of +/-0.01mm with minimal surface preparation.

B2B Die Casting Manufacturing & Partnership FAQ

Answer: Yes, we provide a true end-to-end service. We offer a full-chain service—from product design optimization to finished product delivery:

Free DFM Analysis: Before mold opening, our engineering team will conduct a comprehensive Design for Manufacturability (DFM) analysis of your 3D model, simulate metal flow (mold flow analysis), predict and address potential porosity, shrinkage, and deformation issues, and optimize the gate design to reduce defect rates.

Precision Mold Manufacturing: We have our own high-standard mold workshop, using premium steel grades such as H13 and SKD61. Equipped with wire EDM machines and high-speed CNC machines, we ensure mold precision reaches ±0.005mm.

Integrated Production: We offer a complete production line—from high-pressure die casting/low-pressure die casting to CNC precision machining and surface treatment (spraying, electroplating, anodizing). Simply provide us with a design concept, and we’ll deliver fully finished components ready for direct assembly. Quick response: From drawing confirmation to the delivery of the T1 sample, the fastest turnaround time is only 15–20 days.

Answer: Quality control is the lifeblood of die casting. We employ automotive-grade process controls to eliminate defects:

Vacuum Die Casting Technology: For parts with high performance requirements, we employ a vacuum-assisted die-casting process that evacuates air from the mold cavity, significantly reducing porosity and increasing part density by more than 30%. These parts can even undergo T6 heat treatment without developing bubbles.

Real-time Process Monitoring: Each die-casting machine is equipped with a real-time monitoring system that collects and locks critical parameters—such as injection speed, pressure, and temperature—at millisecond-level resolution, ensuring process consistency for every molding cycle.

Full-size Inspection Capability: The laboratory is equipped with a three-coordinate measuring machine (CMM), an X-ray flaw detector, and a spectrometer. For each batch, a full-size inspection report (FAI) must be prepared for the first part produced. Critical dimensions undergo CPK statistical analysis to ensure dimensional stability in mass production (CPK > 1.33).

Nondestructive Testing (NDT): We can perform 100% X-ray inspection or air-tightness testing on critical load-bearing components according to customer requirements, ensuring zero internal defects.

Answer: We are committed to reducing your long-term amortization costs through high-quality molds.

Transparent mold quotation: Mold costs are precisely calculated based on dimensions, complexity, steel grade (such as H13, SKD61, 8407), and cavity count (e.g., 1-cavity, 2-cavity, etc.), with no hidden fees.

Ultra-long mold life commitment:

  • Aluminum alloy mold: Guaranteed service life ≥ 100,000 cycles.
  • Zinc alloy mold: Guaranteed service life ≥ 500,000 cycles.

If the mold prematurely fails due to steel or heat treatment issues, we promise free repair or re-opening.

Mold Ownership and Custody: The mold remains the property of the customer. We provide lifetime free maintenance services (including regular polishing and replacement of wear parts). You are welcome to conduct a video inspection of the mold at any time, or have it inspected by a third party.

Flexible design changes: During product iterations, we offer modification services. Minor adjustments can be completed within 3–5 days; for major changes, we only charge for materials and labor costs, and the T1 sample will be re-validated.

Answer: We are highly proficient in the properties and applications of various alloy materials and can recommend the optimal solution based on your operating conditions.

Answer: By leveraging technological cost reductions and economies of scale, we offer you the most competitive total cost of ownership (TCO):

Lightweight design: Through topology optimization and CAE simulation, while maintaining structural integrity, we reduce wall thickness and eliminate redundant material, directly lowering both the weight per part and material costs (typically achieving weight reductions of 10% to 20%).

Near-net-shape manufacturing: High-precision molds minimize the need for subsequent CNC machining, saving on costly machining time and tooling expenses. With loss.

Waste Recycling Mechanism: Runner material and scrap parts generated from die casting are immediately remelted and reused within the factory, achieving a material utilization rate of over 95%. The resulting cost savings are passed on to our customers.

Tiered Pricing and Rebates: We offer highly attractive tiered pricing based on annual purchase volume. Larger volumes may also qualify for year-end rebates or discounts. Mold fee refund policy.

Logistics Optimization: Professional packaging design solutions to maximize container load rates and reduce shared ocean freight costs.

Die Casting Knowledge FAQS

The die-casting services in Scojet are with a range of materials to produce precise and intricate shapes. With perfect surface finishes and stunning details. The products have higher heat and pressure resistance and are more durable than others.

For cold chamber die casting, the metal is first heated in a separate furnace to a molten state. The molten metal is then conveyed to the casting machine and fed into the machine’s chamber. The machine uses a pressurized plunger to press the molten metal into the die cavity. This separate process directly distinguishes cold chamber die casting from hot chamber die casting.

Cold chamber die casting is ideal for metals with high melting points and high corrosivity. In contrast to hot chamber die casting, cold chamber die casting solves the corrosion problem by separating the furnace from the ejector assembly. The process begins with the furnace scooping molten metal into the ejector chamber through the pour hole. Next, a plunger presses the metal through the ejection chamber into the mold at a pressure of 2,000 to 20,000 psi.
