Optimizing Die Lubricant to Enhance Metal Flow in the High-Pressure Die Casting Process

Nowadays, technological innovations in inspection have enabled great progress in increasing the
safety of cast metals parts used in the automotive industry. In the aluminium high-pressure die casting
process, porosity is the most common problem which affects the mechanical strength and subsequent
part safety after assembly and installation. Therefore, the manufacturer must design and instrument the
casting process to minimize such defects, while still maintaining production capabilities to compete in
terms of quality and cost. Manufactures can include technology to promote air purging with vacuum,
the use of CAD/CAM/CAE to evaluate mold design or the use of various materials in the molded parts
to ensure proper heat transfer. In this project, one method was used to help reduce pores that occur
from moisture in the mold caused by remaining die lubricant in cavity. This is one of the causes of
porosity defect in the workpiece. The different die lubricant used have a significant impact on the
speed of the injection. We check the temperature with an infrared camera while producing to compare
each coating afterwards can be inspected using the leak test method and X-ray examination to confirm
quality.
