Die Casting Process becomes more and more popular in industrial manufacturing,because these die casting parts can be satisfied with some specific functional demand of the parts in many industries. If these parts are made, the casting die should be designed and manufactured, with it ,and process in high volume in high efficiency. The process involves several steps in die casting process, includes melting the cast metal, preparation of the mold, inject the molten metal, cools and solidifies the cast part, eject the part from the mold. As one of professional die casting manufacturers, TangSheng Hardware Technology offer guideline for die casting.
What Are The Steps In Die Casting Process?
Hot Chamber Die Casting Process
The casting process is suitable for some low melting points metal alloys, such as zinc alloy, tin, lead and Bismuth. The features of it is fast cast cycle, high precision, low shrankage and recycled.
- Melting The Cast Metal
- Preparation Of The Casting Die
- Injecting The Molten Metal
- Cooling and Solidifying The Cast Part
- Eject The Cast Part out of From The Die
- Trimming And Finishing
- Inspecting The Cast Part And Quality Control
| Alloy Type | Melting Range | Strength | Toxicity | Primary Use |
|---|---|---|---|---|
| Zinc (Zamak 3/5) | 385–480°C | High | Low | Automotive, electronics |
| Tin (Sn-Ag-Cu) | 180–320°C | Medium | Low | Electronics, soldering |
| Lead (Pb-Sb) | 250–350°C | Medium | High | Batteries (declining use) |
| Bismuth (Field’s Metal) | 47–170°C | Low | Low | Prototyping, medical |
Cold Chamber Die Casting Process
The die Casting Process is favor of higher melting points metal alloys, such as Aluminum alloy, Copper, Iron, Stainless steel, Gold and Silver. The process maintain slow cast cycle, high precision, high shrankage and low ductility, suitable for large size cast parts.
- Melting The Cast Metal:j
- Preparation Of The Casting Die
- Injecting The Molten Metal
- Cooling and Solidifying The Cast Part
- Eject The Cast Part out of From The Die
- Trimming And Finishing
- Inspecting The Cast Part And Quality Control
| Alloy Type | Melting Range | Strength | Toxicity | Primary Use |
|---|---|---|---|---|
| Aluminum Alloy | 600-800°C | High | Low | Automotive, aerospace |
| Brass | 885-995°C | High | Low | Electronics, decoration |
| Stainless Steel | 1245–1530°C | Very High | Low | High precision and wear resistance parts |
| Gold | 1064°C | Low | Low | Jewellery, gifts |
| Silver | 960-1000°C | Low | Low | jewelery, electrics |
TangSheng Offers Guideline For Die Casting
 TangSheng Hardware Technology is specializing for manufacturing metal components, which are made by die casting techniques tailored to meet specific requirements or unique designs. Client provide their drawing and design plan to their supplier, hand to their supplier to design the product that they desired. It contains the design of custom product model and creating precisoin molds or dies. Custom die casting projects have OEM and ODM services. Whenever, In accordance with customer’s specific requirements, Supplier should produce high-quality custom die casting components.
Features of Custom Die Casting
- Tailored Solutions: The client present the design requirements and design plan to the supplier, and require the supplier to design the molds or dies to meet the specific requirements of the custom component, so that ensuring the component fits seamlessly into their desired application.
- Material Options: Among various materials like zinc, aluminum, magnesium, or their alloys materials, the manufacturers can choose the best alloy material to make custom die casting components for specific requirements.
- High Precision: Alloy die casting components all have a high accuracy dimension and fine surface finish due to the casting die is machined by cnc machining. So zinc custom die casting is high precision process.
- High Efficiency Mass Production:Â Custom die casting is also high efficiency for producing large quantities, because the molds are reusable and mass production is automated. This is beneficial to enhance production rate and reduce labor cost.
- Diversity Surface Finish and Aesthetics: These custom die-cast parts can be finished with various surface finishes, afterwards, they need minimal post-process. Through additional treatments like polishing, plating, or painting to meet appeal decoration or functional needs.
