Thermoform Glass Into Abs Sheet

During the molding process itself a sheet is clamped into a frame that holds it like a piece of glass in a window frame.

Thermoform glass into abs sheet.

As the sheet touches the mold surface it cools down causing that part to stop drawing. Overview of thermoforming thermoformable plastic sheets from professional plastics. This selection of materials are best known for their excellent formability in addition to their individual traits of toughness chemical resistance and heat resistance for example. Many packaging suppliers make the sheet and thermoform it into the required pack shape while some packer fillers thermoform trays from a pre supplied reel of sheet material place the product into it and heat seal a flexible lid onto the tray all on one machine.

The frame moves into an oven that heats the sheet to a high temperature commonly between 350 and 400 degrees. Since most stretch forming operations don t involve a lot of stretching wall thickness of the final part is relatively uniform. At that temperature the sheet becomes quite rubbery and will stretch with ease. This is the simplest thermoforming technique.

Once the sheet is heated the container can be formed using different methods. Abs thermoform plastic sheets due to its low cost and superior physical properties abs acrylonitrile butadine styrene is one of the most popular thermoform plastics used for vacuum forming. Abs produces detailed parts that are tougher and more rigid than other plastics.
