MANUFACTURING PROCESSES
Extrusion
Injection moulding
Extrusion is a process used to create objects with a defined and fixed cross section. The material is pushed or pulled through a die of a desired cross section.
In engineering, injection molding is a semi-continuous process that involves injecting a polymer, ceramic, or a molten metal into a cold-pressed, closed mold through a small hole called a gate.
Blow moulding
Blow molding is a process used to make hollow plastic parts thanks to the expansion of the material. This is achieved by means of the pressure exerted by the air on the walls of the preform, in the case of injection-blown, or of the parison, if we speak of extrusion-blown.
Immersion moulding
In plastics processing, dip molding is a process of shaping of plastics by moulding. The coating of components with PVC has many applications. Plastic dip moulding is a technique where metal parts are coated with a plastic vinyl material. It is used to protect and make the metal parts more resistant to scratches and abrasions
Mangling
A mangle or wringer is a mechanical laundry aid consisting of two rollers in a sturdy frame, connected by cogs and, in its home version, powered by a hand crank or electricity. While the appliance was originally used to wring water from wet laundry, today mangles are used to press or flatten sheets, tablecloths, kitchen towels, or clothing and other laundry.
Foaming
Foams are made by forming gas bubbles in a plastic mixture, with the use of a blowing agent. Foam manufacture is either a continuous process for making laminate or slabstock or a batch process for making various shapes by cutting or molding.
Vacuum forming
Description Vacuum molding is a sand molding technique in which no binder is used, since the part is sufficiently consistent thanks to the vacuum created during its execution in the molding box. It is a relatively modern technique, as it emerged in Japan in the late 1970s.
