It is sheet temperature that dictates the process the end result being not just a better product but also decreased cycle time less scrap less floor space and reduced energy and labor costs.
I can t recommend for.
We manufacture high qualitythermoforming equipment.
This refers to the process of vacuum and pressure forming of two sheets of polycarbonate simultaneously.
Twenty four hours at 176 f 80 c dries most sheets.
Note that the minimum radius of the bend you create is 180 times the thickness of the plexiglass sheet.
To reduce the length of the forming cycle pre dry the sheet in a spare oven and transfer it directly into the forming oven at 176 f 80 c after the drying period.
This article uses a sheet about 1 4 thick so all times are about 10 to 15 minutes per step.

So it happens that you have to use a separate mold on top and bottom platens.
Force the plexiglass into the desired shape.
The only major variable that can affect the forming process is the thickness of the plastic sheet.

It is important to provide sufficient clamping of the sheet during the forming process.
Acrylic oven baking sheet aluminum foil timer felt for handling the acrylic and to prevent scratches tools for forming tools for forming may include.
