Blow Molding: The process of producing a hollow part by forcing air into a soft parison inside a mold (extrusion blow molding), or of forcing air into a heated pre-form that has been made beforehand by injection molding (injection blow molding).
Engraving:Engraving is the practice of incising a design onto a hard, flat surface, by cutting grooves into it.
Injection Molding: A forming process whereby plastic is heated and injected under pressure into a tightly clamped mold so that, on cooling, it takes on the shape of the mold around it.
Rotational Molding: A forming process whereby powdered resin is heated inside a rotating mold so that it coats the inside of the mold and takes on the resultant shape.
Vacuum Forming: A forming process whereby a sheet is heated, then pulled by a vacuum against a mold surface until it takes on the shape of the mold contours. Vacuum forming is a close relative of thermoforming.
