Technology / product information

Aluminum die-casting is a precision manufacturing technology ideal for producing thin-walled parts and complex shapes. In recent years, the demand for aluminum die-cast products has surged in the automotive and home appliance industries, where weight reduction is advancing, requiring high-precision and efficient manufacturing. However, defects such as “flow marks” that occur during the manufacturing process remain a challenge.
At our company, we address this challenge through proprietary technology that suppresses the occurrence of flow marks, utilizing a wide range of die-casting machines from 420 to 800 tons. Our production system, which supports product weights up to 6.5 kg and wall thicknesses of 2–3 mm, provides high-quality aluminum die-cast products from design through to final completion.

Features
✅Manufacturing Technology That Minimizes Flow Marks
+ Strict temperature control of molds and molten metal to improve fluidity.
+ Optimized and standardized casting conditions (temperature, pressure, injection speed) to ensure consistent quality.
+ Reduced gas defects and flow marks by using vacuum systems to remove air from within the mold.
+ Improved venting structures with optimally placed vents for efficient gas evacuation.
+ Improved mold filling by adding overflow mechanisms that effectively release excess gas.
+ Regular mold maintenance, including cleaning and replacement of worn parts, to maintain optimal mold condition.
✅Flexible Production Capabilities with a Wide Range of Machinery
+ Equipped with die-casting machines from 420 to 800 tons, capable of producing parts weighing up to 6.5 kg and supporting thin-walled designs of 2–3 mm.
✅High-Efficiency Production Through Integrated Processes
+ Full in-house production from design and die-casting to secondary processing and finishing shortens lead times and ensures efficient delivery.
