Plastic die casting is not a standard term in manufacturing, as die casting specifically refers to a process where molten metal is injected into a mold under high pressure to create precise parts. However, plastics are typically processed using a different method called injection molding, which is similar in concept but tailored for polymers. 

Key Points:

Injection Molding for Plastics: In injection molding, molten plastic is injected into a mold, cooled, and solidified to form parts. It’s widely used for producing high-precision plastic components, like automotive parts, consumer electronics, and medical devices.

Materials: Common plastics used in injection molding include ABS, polycarbonate, nylon, polypropylene, and others, which have much lower melting points (typically 200–600°F or 90–315°C) than metals used in die casting.

Why Not Die Casting for Plastics?: Die casting is optimized for metals with high melting points (e.g., aluminum, zinc). The equipment, mold materials, and process parameters for die casting are not suitable for plastics, which require different temperature controls and mold designs.

Exceptions or Related Processes:

Some sources might loosely refer to high-pressure injection molding of plastics as "plastic die casting" in non-technical contexts, but this is uncommon and technically inaccurate.

Reaction Injection Molding (RIM): This is a specialized process for plastics (e.g., polyurethanes) that involves mixing reactive liquid components under pressure, which could be seen as analogous to die casting but is distinct.

Thixomolding: A hybrid process that uses semi-solid magnesium or, in rare cases, plastic-like materials, but this is closer to metal die casting than plastic processing.
