Vacuum Formed Trays

vacuum formed trays is one of plastic trays which produced by thermoforming process. Frist step is heating a sheet of plastic then plastic sheet was stretched over a mold over a mold before being forced against it by a vacuum,the plastic tray is manufactured.


Diffirence with standard plastic trays with fixed cavities, the benefites of using vacuum formed trays comes from customized options avaiable.With advantage of lightweight, easy to operation, saving space,welcomed by most of customer.


vacuum formed trays can effective protect your parts or components.They are wide used on packaging trays,lastic tooling trays, precision device trays, medical trays, cosmetic trays, pet product trays, hydroponic planting trays, transportation trays, automotive parts trays etc.
