Injected metal assembly (IMA) process

Injected metal assembly (IMA), a form of insert moulding, is a manufacturing process that uses a molten zinc alloy to join two or more components together to create a single assembled part. The process is similar to injection moulding, but instead of using plastic, it uses zinc. The IMA process starts with the creation of a custom tool with cavities for the two or more components and injection ports. The components are then placed in the tool and the molten zinc is injected. The zinc alloy flows into the cavities and hardens to create a permanent bond between the components.
