Langhe Casting is a trusted provider of high-quality die casting services, specializing in aluminum and zinc alloy components for industries such as automotive, electronics, lighting, and machinery. With state-of-the-art equipment, strict quality control, and years of expertise, we deliver precision-engineered parts that meet international standards.
Die casting is a high-pressure metal casting process in which molten metal is injected into a steel mold (die). Once cooled, the part is ejected with high dimensional accuracy, excellent surface finish, and minimal post-processing needs.
| Parameter | Description |
|---|---|
| Process Type | High-pressure metal injection |
| Materials Used | Aluminum, Zinc, Magnesium alloys |
| Typical Tolerances | ±0.05 mm or better |
| Common Applications | Automotive parts, lighting housings, consumer electronics |
Die casting processes can be classified into several types based on the method of metal injection, casting material, and the equipment used. Each type offers specific advantages depending on the application, alloy, and production volume. At Langhe Casting, we provide both cold chamber and hot chamber die casting solutions to meet diverse customer needs.
| Process Type | Description | Suitable Metals | Main Applications |
|---|---|---|---|
| Cold Chamber Die Casting | Molten metal is ladled into the injection chamber. A plunger forces it into the die cavity under high pressure. | Aluminum, Magnesium, Copper alloys | Automotive engine parts, structural components |
| Hot Chamber Die Casting | Injection mechanism is submerged in molten metal. Metal is injected directly into the die cavity. | Zinc, Lead, Tin alloys | Electronics housings, consumer products, connectors |
| Squeeze Die Casting | Combines casting and forging. Metal is solidified under high pressure in a closed die. | Aluminum, Magnesium | High-strength components, aerospace and automotive parts |
| Vacuum Die Casting | Air is evacuated from the die cavity before injection, improving mechanical strength and reducing porosity. | Aluminum, Zinc | Parts requiring superior surface finish and integrity |
| Semi-Solid Die Casting | Uses metal in a semi-molten (slurry) state for better flow control and dimensional stability. | Magnesium, Aluminum | Complex geometries, high-precision components |

| Question | Answer |
|---|---|
| What is the difference between cold and hot chamber die casting? | Cold chamber is used for aluminum; hot chamber for zinc or magnesium due to melting point differences. |
| What are typical lead times? | Tooling: 2–4 weeks; Production: 1–2 weeks after tooling approval. |
| Can Langhe Casting assist with product design? | Yes, we provide DFM (Design for Manufacturability) support. |
