What is vacuum forming and thermoforming?
Vacuum forming is a simplified version of thermoforming. In which a sheet of plastic is heated to a forming temperature. Furthermore that plastic sheet is stretched onto a single-surface mold, and forced against the mold by a vacuum. However this process can be used to form plastic into permanent objects such as turnpike signs and protective covers.
Probably the reasonable materials for use in vacuum forming or thermoforming are routinely thermoplastics. The most well-known and simplest to use thermoplastic is high effect polystyrene sheeting (HIPS). This is shaped around a wood, basic foam or machined aluminum shape, and can frame to any shape.
In addition Thermoforming offers low-cost tooling. Since the process uses low pressures, the mould can be of inexpensive materials and also mould fabrication time can be reasonably short. It therefore offers several processing advantages over other forming processes like low cost, ease of tooling, efficiency. Even more one of the main benefits of vacuum forming is the speed at which tooling can be produced.
At forming plastics we have various vacuum holding machines that are particular sizes and fill assorted necessities. It reduces cost and quickens time. We can vacuum thin material for thin packaging to thick gauge material for strong parts like mudguards and dashboards. Vacuum formed products are all around us and play a major part in our daily lives.
The materials which we utilized for Vacuum Forming are:
Acrylic (Plex, Lucite® and Acrylite®)
HIS (High Impact Styrene or Polystyrene)
PETG (Vivak®, PET-G or Spectar®)
Polycarbonate (Makrolon® or Lexan®)
Polyethylene (HDPE or LDPE)
Polypropylene (PP or PolyPro)
PVC or Rigid Vinyl.
