As deck boats have become bigger and broader and pontoon boats have become more powerful, performance-ready and posher, the two categories have drawn closer. Sporty and stylish, deck boats come in a variety of configurations, from sunpad-topped sterndrive power to outboard engines directed by single-side console.
Vacuum forming is a technique that is used to shape a variety of plastics. In school it is used to form/shape thin plastic, usually plastics such as; polythene and perspex. Vacuum forming is used when an unusual shape like a dish or a box-like shape is needed.
The blow molding process begins with melting down the plastic and forming it into a parison or in the case of injection and injection stretch blow moulding (ISB) a preform. The parison is a tube-like piece of plastic with a hole in one end through which compressed air can pass.ontainers such as jars often have an excess of material due to the molding process. This is trimmed off by spinning a knife around the container which cuts the material away. This excess plastic is then recycled to create new moldings.
