injectionsoufflage

Injectionsoufflage is a manufacturing process that combines injection molding and blow molding techniques. It is primarily used for the production of hollow plastic parts with complex shapes and high precision. The process begins with injecting a preform, which is a partially formed hollow part, into a mold cavity. Subsequently, a blowing operation is performed, typically by injecting compressed air or gas into the preform, expanding it to conform to the shape of the mold.

This dual-step process allows for greater control over wall thickness distribution and the creation of intricate features that would be difficult to achieve with standard blow molding alone. Injectionsoufflage is particularly well-suited for producing containers, cosmetic packaging, automotive components, and other parts where precise dimensions and detailed surface finishes are required. The preform is often injected with a higher melt temperature than in traditional injection molding, facilitating easier expansion during the blowing stage.

The mold used in injectionsoufflage is designed to both form the preform and then allow for the subsequent expansion and cooling of the final part. This method offers advantages such as improved optical clarity, reduced material waste, and the ability to create parts with integrated handles or other complex geometries. It is a versatile technique for manufacturing a wide range of hollow plastic products.
