How thick should plastic be for vacuum forming?

Vacuum forming sheet thickness may range from 0.0005 to 0.50 inch (0.0127 to 12.7 mm). However, for prototype applications, the Formech machines are limited to sheet thicknesses between 0.0005 to 0.25 inch (0.0127 to 6.35 mm).

Can you vacuum form PETG?

PETG (Polyethylene terephthalate) is a transparent thermoform plastic that offers cost-effective vacuum formed parts with deep draws and precise details. PETG is significantly less prone to cracking than acrylic (Plexiglas).

Can PETG be thermoformed?

PETG (polyethylene terephthalate glycol-modified) plastic is a variation of PET plastic. PETG plastic can be molded during thermoforming for blister packaging and trays.

Is vacuum forming good for large parts?

Types of Vacuum Forming Machines Industrial vacuum forming machines, such as industrial vacuum forming machines from Ridat or Belovac, are ideal for commercial applications and manufacturing large parts.

Can you vacuum form PET plastic?

While plastics often get a bad rap, there are actually many sustainable options for thermoforming. Vacuum forming, as we stated before, can process many highly recyclable materials. Plastics, such as PET and HDPE, for instance, are accepted by nearly all curbside recycling centers.

What thermoform means?

Thermoforming – Thermoforming is a general term that refers to the process of transforming a plastic sheet into a 3-dimensional shape by using heat, vacuum, and pressure.

What additives are used in vacuum forming?

There are many different types of plastics that are used in vacuum forming and these are some of the more common ones:

  • Acrylonitrile Butadiene Styrene (ABS)
  • Acrylic – Perspex (PMMA)
  • Co-Polyester (PETG)
  • Polystyrene (HIPS)
  • Polycarbonate (PC / LEXAN / MAKROLON)
  • Polypropylene (PP)
  • Polyethelene (HDPE)
