Low-Pressure Die Casting
Key
Low-pressure die casting (LPDC) is a common process used in foundries today in which molten metal slowly fills the die, reducing turbulence. Automotive applications include wheels, as well as suspension, steering and engine components. Non-automotive parts commonly made by the LPDC process include pipe benders and bell housings. LPDC allows the achievement of castings with very good metallurgical quality. Advantages of LPDC include:
- High yield achievable (typically over 90%)
- Reduction of machining costs, thanks to the absence of feeders
- Excellent control of process parameters which can be obtained with a high degree of automation
- Good metallurgical quality, thanks to a slow, non-turbulent filling and controlled solidification dynamics, resulting in good mechanical and metallurgical properties of the castings, including low porosity
Critical issues for low-pressure die casters include melt cleanliness, hydrogen content, furnace pressure, casting temperature, casting cycle timing and mould coating and maintenance.
Pyrotek’s foundry team focuses on improving metal quality and die casting performance with full set of feeder system consumables: sprue filter, sprue bushings, inserts, intermediate tubes, seals, gaskets, and stalk tubes. Each product category come in variety of materials and multiple designs to reduce freeze-ups during casting, resist to molten aluminium attack and erosion, reduce shrinkage, and more.
- Improved metal quality
- Reduced scrap
- Increased process efficiency
