Pressure Forming Plastic Sheets

Plastics design manufacturing is one of the leading suppliers of custom plastic pressure forming services across a variety of industries.

Pressure forming plastic sheets. Our company can also provide product design and manufacturing engineering assistance and is as9100 2016 iso 9001 2015 certified. Vacuum forming during the vacuum forming process plastic is heated in a high temperature oven to make it pliable. Twin sheet thermoforming is a process of vacuum or pressure forming two sheets of plastic essentially simultaneously with a separate mold on the top and bottom platens. Pressure thermoforming is a plastic manufacturing process in which compressed air is used to push the back of the plastic sheet against the mold.

In this case however the sheet touching the mould remains close to its original thickness. Twin sheet forming twin sheet forming uses distinct top and bottom molds heat and vacuum to create a void between two sheets of plastic while forming a strong edge seal. Drape forming is similar to straight vacuum forming except that after the sheet is framed and heated it is mechanically stretched and a pressure differential is then applied to form the sheet over a male mould. Pressure forming is a thermoforming process similar to vacuum forming but it utilizes a high pressure air assist to create significantly better part definition.

The engineering department at universal plastics is staffed from 7 00 a m to midnight monday through friday and any member of the department is available to answer any vacuum forming pressure forming or twin sheet thermoforming related design or engineering questions share his expertise and offer his advice. A vacuum is formed between the mold cavity and the thermoplastic sheet. Pressure forming is an enhancement to the vacuum forming process. Pressure forming plastic is an enhancement of vacuum forming making it one of the more advanced forms of thermoforming we begin the process as with vacuum forming.

Once the plastic has been molded it remains in the molds and while still at its forming temperature the two molds are brought together under high pressures and the two. To start we add a vessel on the opposite side of the sheet from the mold. At your request we have a design manual available for vacuum forming pressure forming and twin sheet moulding detailing our services. Pressure forming is an advanced plastic manufacturing process whereby a plastic sheet is molded to a complex and detailed shape utilizing a single sided mold to create the formed shape using vacuum pressure on opposing sides of the sheet.
