1 drape forming acrylic sheet.

Vacuum forming acrylic sheet temperature.

Cold forming is possible. Before forming the sheet s temperature must be higher than the desired temperature to allow for cooling that will occur prior to the start of forming. There are many acrylic thermoforming techniques. Hips high impact polystyrene white easy forming.

Temperature can be controlled thermostatically within 10 f 5 c between 140 350 f air velocities across the sheet range between 200 1000 feet per minute 1 5 m s. High density polyethylene hdpe which requires a core temperature of approximately 280 f for optimal forming. To achieve this core temperature the former must calculate the temperature differential on both sheet surfaces. Tighter radii may result in crazing or cracking of the coating.

Forms to a high definition. Mold set lower orienting normal forming upper temperature processing limit temperature core temp. Processing limit f c f c f c f c f c acrylonitrile butadiene styrene abs 185 85 260 127 280 138 300 310 149 154 360 182 acetate 160 71 260 127 280 138 310 154 360 182 acrylic pmma 185 85 300 149 325 163 350 177 400 204. The clamping system exerts constant uniform pressure on all sides as the sheet becomes soft.

Even temperature distribution throughout the sheet s thickness is recommended. Forms to a high definition. Line bending or thermoforming a brasion resistant acrylic sheet is not recommended. Most widely used material.

Forming temperature the forming range for acrylic sheet is 290 320ºf 142 160ºc. Temperatures throughout the oven are uniform. Tends to be brittle and temperature sensitive. Never heat acrylic sheet in a kitchen oven.

Sheet surface temperature will directly correspond to material gage. However we shall look at the most common three. For example let s use 0 250 in. To calculate the minimum bend radius of curvature multiply the thickness of the sheet to be used by 330.
