What Is High Pressure Die Casting?
High Pressure Die Castings (HPDCs) are light-weight alternative components made from forcing molten metals into a mold at high speed and pressure. Casting molten metals allows for once multi-piece, welded-together structures to now be singular, aluminum castings – performing the same task with less mass and variability.
Manufacturers have adopted these components for their added value of:
- High-volume, high-tolerance, high-strength components
- Flexibility for creating complex shapes – particularly in the automotive and aerospace sectors
- Light-weight capabilities – enabling more compact, fuel-efficient vehicles
- Advancing engine design and sophisticated vehicle construction
High Pressure Die Castings are now commonly used within:
- Key body structures – pillars, shock towers, floor and rear rails
- Complex shapes
- Chassis structures – engine cradles, suspension links
Tailored Heat Treatment
With the increased flexibility afforded by HPDCs, comes demanding requirements on the metallurgical properties of the castings.
For years, Can-Eng has developed, tested, and iterated its furnace systems to provide solution, quenching and aging treatment systems for today’s exacting tolerances for T4, T5, T6, and T7 processes; while maintaining a product’s dimensional stability.
These systems are designed for ultimate flexibility, maximizing system efficiencies:
- Allowing reactionary or planned expansions
- Minimizing required floorspace
- Minimizing capital and operating costs
- Capable of meeting relevant AMS 2750E, NADCAP, and AIAG CQI-9 standards
Every part, and its properties, is unique. Can-Eng works with their clients to develop custom fixtures for safely and efficiently heating and moving parts – minimizing scrap.
Further to Can-Eng’s understanding of aluminum and High Pressure Die Casting heat treating, Can-Eng’s unique Basketless Heat Treatment Systems (BHTS®) and Precision Air Quench (PAQTM) were both developed, from the beginning, with High Pressure Die Castings in mind.
These systems have been custom engineered to deliver uniform heating and quenching rates across individual parts; resulting in the anticipated metallurgical properties, lower maintenance costs, and enabling lean manufacturing practices.
