Introduction to vacuum forming process: Vacuum forming is a plastic processing technology, which mainly involves heating flat plastic sheets to soften them, then vacuum adsorbing them onto the surface of the mold, cooling and forming them. It is widely used in plastic packaging, lighting, advertising, decoration and other industries
Blister packaging products mainly include: blister, tray, blister box, also known as vacuum hood, blister, etc. Blister packaging equipment mainly includes: blister molding machine, punching machine, sealing machine, high-frequency machine, refractive index machine. Packaging products formed by packaging can be divided into: plug-in, suction card double blister, half blister, folded blister, triple folded blister, etc
By using vacuum forming technology, transparent plastic sheets are made into specific protruding transparent plastics, which are covered on the surface of the product to protect and beautify the product. A layer of solute material is pasted on the surface of ordinary plastic sheets to give the tray a solute like feel, which is used to improve the grade of packaging products. The vacuum forming tray made of special process modified materials has a surface resistance value of less than 10 times the discharge resistance. It is mainly used for electrostatic trays of electronic and IT products
The lowest cost molds used in vacuum forming production are gypsum molds, followed by electroplated copper molds, and the most expensive are aluminum molds. The molds have small holes drilled for vacuum adsorption and heating of hard sheets to form vacuum formed products
