Product Description

Custom Die Casting Service For Zinc And Aluminum Of Shape Intricate Conponents







At JYH-precision machining,die casting is a remarkable metal fabrication process that harnesses the power of high-pressure molten metal to shape intricate parts. The materials of choice are typically non-ferrous metals such as zinc, copper, aluminum, magnesium, and various alloys.



Advantages of Die Casting Process


Die casting stands as a significant technique in metal fabrication, esteemed for its cost-effectiveness and user-friendly nature.

The advantages it brings:


  • Accomplish intricate part designs
  • Reduce labor expenditures
  • Attain varying wall thicknesses
  • Achieve stricter tolerances


Disadvantages of Die Casting Process


  • Incompatible with metals boasting elevated melting points
  • Incompatible with extensive sheet metal components
  • Substantial die expenses
  • Extended lead times


Die Casting Alloys


Die casting commonly employs non-ferrous alloys prized for their robust mechanical attributes. These non-ferrous components contribute to the alloys' low melting points, which align with their strong mechanical performance.Below, we list a few popular alloy options:


Aluminum Alloys

Aluminum alloys possess versatile qualities for various product uses, with 380.0 being a popular die casting preference. Other options like Alloys 360, 390, and 413 also exist, chosen based on factors such as specific application requirements.


  • Elevated operational temperatures
  • Remarkable resistance to corrosion
  • Lightweight nature
  • Notable strength and hardness
  • Favorable combination of stiffness and strength-to-weight ratio


Zinc Alloys

Zinc alloys offer remarkable strength, resilience, stability, efficiency, and cost-effectiveness.


A variety of zinc alloys are available for utilization. Nevertheless, the prevalent zinc materials for die casting include Zamak #2, #3, #5, #7, ZA8, and ZA27, celebrated for the ensuing qualities:


  • Enhanced Castability
  • Reduced Cycle Duration
  • Prolonged Die Lifespan


Other Alloys


Die casting parts can also be crafted from alternative alloys such as Bronze, Brass, lead, and tin.


Bronze, specifically white bronze, finds favor in the jewelry sector for die casting. It boasts a color akin to white gold and stainless steel alloys while remaining an ideal choice due to its lower melting point.








  • Mold and Sample Lead Time


For standard projects, we ensure the completion of mold creation and delivery of the initial sample within a time frame of 25 to 30 days.

For expedited projects, our commitment is to accomplish mold creation and provide the sample within a maximum of 15 days.






  • Payment terms for Order


For mold/tooling and samples: 50% deposit on order, remaining 50% post sample approval.

For new customer production orders: 30% advance payment, balance 70%. Long-term valued customers enjoy even better terms: 100% payment on delivery.Can be negotiation.





  • How to Address Non-Conformity or Other Disputes When Raised



Quality is our priority in every step, from production to QC. While we maintain high standards, in rare cases of non-qualified shipments, we'll collaborate to minimize losses, learn, and ensure future excellence. If issues arise, we'll work with our clients for solutions including compensation or replacements.





Types Of Die Casting Processes


In the industrial realm, two main methods for die casting are the hot chamber and cold chamber processes.

Below, we outline the details of these two processes.




Hot-chamber die casting


Aluminum Alloy Die Casting Service ISO9001 Semi Permanent Mold 2




Hot-chamber die casting utilizes a molten metal reservoir to fill intricate molds quickly, making it ideal for low-melting point alloys like zinc and tin. 



Cold Chamber Die Casting

Cold chamber die casting is excellent for handling high melting point materials like aluminum, preventing damage to the pumping system caused by extreme temperatures. In this method, molten material is poured into a cold chamber before being injected into the die, utilizing a hydraulic system similar to hot chamber casting.



Surface Finish


Surface finishing is crucial in die casting to enhance product aesthetics and functionality, ensuring parts meet precise specifications and provide optimal performance.

Die Casting Process


Whether it's hot or cold chamber die casting, the standard procedure involves injecting molten metal into a die mold using high pressure.

Here are the detailed steps in the die casting process:



Aluminum Alloy Die Casting Service ISO9001 Semi Permanent Mold 8


At the outset, clean the die to eliminate impurities and apply lubrication for smoother injection and product removal. Once cleaned and lubricated, firmly close the die with high pressure.



Melt the chosen metal and pour it into the shot chamber. The method differs based on the process being used.


While the die is closed, allow the metal to cool and solidify. The resulting solid material will take on the shape of the mold design.



After unclamping the die mold, an ejection mechanism will push the solid casting out of the mold. Make sure the product has fully solidified before ejecting.



This marks the final step, involving the removal of excess metal from the sprue and runner on the finished product. Trimming can be done using a trim die, saw
