Product Description

Custom Die Casting Mould Service For Aluminum Alloys Of Complex Conponents




What is the Die Casting service:




ISO9001 High Pressure Die Casting Service Nitride Die Casting Permanent Mold 0Die casting is a remarkable metal fabrication process that harnesses the power of high-pressure molten metal to shape intricate components. This technique relies on a pair of meticulously machined, hardened tool steel dies, akin to precision molds, which guide the metal into its final form. The materials of choice are typically non-ferrous metals such as zinc, copper, aluminum, magnesium, and various alloys.


For optimal results, hot- or cold-chamber machines are employed based on the metal's characteristics. While die casting involves significant initial investments in equipment and molds, it excels in high-volume production. Its streamlined four-step process ensures cost-effectiveness, making it ideal for crafting numerous small- to medium-sized components. 



As an ISO 9001:2015 certified company, we operate multiple manufacturing facilities equipped with advanced technology to craft top-notch components. With swift turnaround times, upon uploading a design file, you can anticipate receiving a quote and DFM analysis within just 12 hours.



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
  • 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.




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.



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:


1. Clamping

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.


2. Injection

Melt the chosen metal and pour it into the shot chamber. The method differs based on the process being used. For example, the shot chamber remains cold in cold chamber die casting but is hot in hot chamber die casting. Following this, inject the metal into the die using high pressure generated by a hydraulic system.


3. Cooling

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.


4. Ejection

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.


5. Trimming

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, or other methods. The removed metal portions are recyclable and can be reused in the process.




Hot-chamber die casting


ISO9001 High Pressure Die Casting Service Nitride Die Casting Permanent Mold 3




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.

Factors Influencing Die Casting Costs


Die casting is typically an economical manufacturing method, yet costs can vary due to multiple considerations. Here are key aspects to contemplate for optimal cost-effectiveness in your die casting project:


  • Material Cost

The selection of materials significantly impacts die casting expenses. Certain materials hold higher price tags, and the overall cost of die casting materials tends to exhibit a general upward trend, albeit with fluctuations.


  • Production Cost

Production costs hinge on three pivotal elements: tooling costs and die casting expenses. Your chosen production processes, technological strategies, mold fabrication procedures, and upkeep efforts all interplay to influence tooling expenses, which can potentially be substantial.



  • Mold Cost

Mold costs are contingent upon the manufacturing approach employed. For instance, employing CNC machining amplifies mold costs due to the capabilities and benefits inherent to the method."


  • Impact on Costs of Secondary Operations

Consider the expenses related to secondary operations, including tasks like trimming, as they factor into the overall die casting expenses. Thus, the scope, efficiency, and success of secondary operation costs become significant considerations.

  • Finishing Cost

The cost of finishing is influenced by the chosen finishing technique. For instance, processes like electroplating will incur greater finishing expenses compared to painting.





Die Casting:


The term "die casting" aptly describes the process, as it centers around the use of specialized molds known as "dies." These dies are meticulously crafted from durable steel through advanced techniques like CNC machining. During the process, liquid metal is injected into the die, taking its desired shape as it cools. The die is composed of two halves: the fixed half, which remains stationary and connected to the casting apparatus, and the ejector half, which can move.


Sand Casting vs. Die Casting:


In the realm of metal fabrication, two prominent techniques stand out: sand casting and die casting. The key distinction lies in the composition of the molds employed. While die casting relies on precisely crafted metal molds (dies), sand casting employs molds made from sand. Additionally, die casting is most suitable for non-ferrous metals with lower melting points, whereas sand casting offers a broader spectrum of compatibility.


Injection Molding vs. Casting:


The mechanics of injection molding and casting bear a resemblance, involving the injection of molten material into a mold that subsequently cools to take shape. However, there's a pivotal divergence. Injection molding specializes in plastics like ABS, polypropylene, TPU, and polyethylene, crafting intricate plastic parts. In contrast, die casting focuses on low-melting-point metals, producing finely detailed metal components.
