Custom Metal Die Casting Services | Aluminum & Zinc Die Casting Manufacturer

Product Overview

Our metal die casting services provide high-precision, high-volume production solutions for complex metal components. Using advanced high-pressure die casting technology, molten metal is injected into durable steel molds to create parts with excellent dimensional accuracy and surface finish.

With over 20 years of manufacturing experience, Qingdao Ronghai Mould offers custom die casting parts tailored to meet OEM and industrial requirements across multiple industries.

What is Die Casting?

Die casting is a manufacturing process in which molten metal is injected under high pressure into a mold cavity, producing consistent and durable components with tight tolerances.

This process is ideal for mass production of complex geometries, thin walls, and high-strength parts, making it widely used in automotive, electronics, and industrial sectors.

Our Die Casting Capabilities

• Aluminum Die Casting

• Zinc Die Casting

• Magnesium Die Casting

• High-Pressure Die Casting (HPDC)

• Precision CNC Machining (Post-processing)

• Surface Finishing (Powder Coating, Anodizing, Plating)

We support full-process manufacturing, from mold design to final assembly.

Materials We Work With

• Aluminum Alloys (ADC12, A380, A356)

• Zinc Alloys (Zamak 3, Zamak 5)

• Magnesium Alloys

These materials are widely used due to their lightweight properties, corrosion resistance, and excellent mechanical strength.

 Die Casting Process

Our standardized die casting workflow ensures consistent quality:

1. Mold Design & Manufacturing

2. Die Preheating & Clamping

3. Molten Metal Injection (High Pressure)

4. Cooling & Solidification

5. Ejection & Trimming

6. Surface Finishing & Inspection

This process enables fast cycle times and repeatable high-quality production.

Key Advantages

• High dimensional accuracy and tight tolerances

• Excellent surface finish (reduces secondary machining)

• High production efficiency for large volumes
