Die Casting - An Insight into the Intricate Metal Forming Process
Die casting is a metal forming process where molten metal is injected at high pressure into steel molds or dies. Due to the high pressures involved, it results in products with very tight tolerances and precise dimensional specifications. This helps produce intricate components with complex internal passages in high volumes, at competitive costs compared to other manufacturing processes.
History and Applications
It is a relatively old manufacturing technology that was first developed in the late 18th century for producing metal buttons and thimbles. Over the years, advancements in metal alloys and casting equipment led to expanding applications of it, especially for zinc and aluminum. Today, commonly die cast metals include aluminum, zinc, magnesium, copper and tin-based alloys. Major industries using die cast components include automotive, industrial equipment, electronics, hardware, and household appliances. Common applications are engine parts, transmission components, housings, casings, and covers for electronics, tools, and consumer goods. It accounts for over 60% of all aluminum cast parts produced globally.
Different Methods
There are two main casting methods in use today - hot chamber and cold chamber Die Casting . Hot chamber machines maintain molten metal at a high temperature inside a holding furnace. Cold chamber machines solidify molten metal in a shot sleeve before injecting it into the die under pressure. Within these, there are further variants depending on the type of filling method - gravity, low/high pressure, and squeeze casting. Hot chamber casting is preferred for zinc and tin-based alloys, while aluminum alloys are commonly cold chamber die cast. Each method has merits suited for certain alloy compositions and part sizes/thicknesses.
Process Steps
The key steps involved in casting are:
1. Preparation of die and mold cavity
2. Melting and alloying of metal
3. Metal conditioning and transfer
4. Shot delivery into the die cavity
5. solidification under applied pressure and cooling
6. Die opening and part ejection
7. Finishing of cast parts
The die or mold containing the cavity of desired part shape is first prepared using tool steels. Molten metal at 700-800°C is transferred and conditioned in the shot sleeve of the Die Casting machine. On trigger, a shot of melt is injected rapidly into the die cavity under very high pressures of 600-1500 kg/sq cm before solidifying. Accurate temperature control is vital to obtain quality castings.
Design Considerations for Die Cast Parts
Designing die cast parts requires careful planning to ensure production feasibility, dimensional accuracy, and assembly/performance needs. Key factors considered are part size/weight limitations, wall thickness variations and thick/thin sections, draft angles, gates and risers placement, machining/finishing requirements post casting, functional lives under service loads/temperatures, and surface finish needs. Finite element analysis involving thermo-mechanical simulations is often used at the design stage to validate castability. Functional designs help achieve dimensional consistency and elimination of defects in high volume production.
