Insert molding is a specialized injection molding technique that integrates preformed components, such as metal or plastic parts, into a single molded product.
The insert molding process begins with placing the insert, which can include threaded inserts, electrical components, or metal reinforcements, into the injection mold. Molten plastic is then injected around the insert, encapsulating it and creating a unified, multi-material component.
Insert molding expands the capabilities of plastic and can help lower overall product cost by reducing the amount of costly metals needed to manufacture products. An insert can be made of metal or another plastic.
The insert molding process simplifies the production workflow, allowing for quicker turnaround times and higher productivity.
Insert injection molding enables the integration of various materials and components, offering various design possibilities.
The bond between the insert and the plastic material is incredibly strong, providing improved structural integrity and durability.
