How many types of vacuum forming are there?
There are two basic types of molds—male or positive (which are convex) and female or negative, which are concave. With male molds, the sheet of plastic is placed over the mold to contour the inside dimensions of the plastic part.
What types of products does the process of vacuum forming create?
Numerous household items are made from vacuum forming plastic. Think about your own home; the plastic bathtub in your bathroom, the plastic utensils, and appliances that can be found in your kitchen, the garden equipment that is stored in the shed.

What is the role of vacuum in vacuum forming?
A vacuum is applied sucking the sheet into the mould. The sheet is then ejected from the mould. In its advanced form, the vacuum forming process utilizes sophisticated pneumatic, hydraulic and heat controls thus enabling higher production speeds and more detailed vacuum formed applications.
What scale of production is vacuum forming?
Original equipment manufacturers (OEMs) utilize heavy gauge vacuum formed components for production quantities in the range of 250–3000 units per year. Vacuum-formed components can be used in place of complex fabricated sheet metal, fiberglass, or plastic injection molding.
How is forming process done?
Forming is the process of obtaining the required shape and size on the raw material by subjecting the material to plastic deformation through the application of tensile force, compressive force, bending or shear force or combinations of these forces.
What are the stages of vacuum forming?
Make the mould. Firstly,a mould is constructed in the shape that the plastic will form around.
What material is best for vacuum forming?
