1. Forming Temperature The normal temperature for forming acrylic sheet is about 160 degrees ~185 degrees (320F~365F), however if the part being formed has small sharp radii, it may be necessary to raise the temperature step by step to a maximum of 200 degrees (392F) providing the sheet has not been exposed to moisture or high humidity. 2. Heating Method 2-1) Forced Air Circulating Oven 2-2) Electric Infrared Oven a) The difference in temperature, particularly in a thicker sheet, between the surface and the core of sheet during the heating or warming up. This problem can cause over-heating on the surface and mis-forming because the core is too cold. The solution to this problem is to lower the voltage and heat the sheet more slowly. b) The outside circumference for the sheet will not get enough heat. This may be caused by the clamping device cutting the infrared ray and transferring the heat away from the sheet into the metal causing the sheet to stretch unevenly resulting in thin bottom radii. The solution to this problem may be two-fold. 3. Cautions Please keep in mind following special properties of acrylic sheet when you heat it. 3-1) Sheet shrinkage due to heating 3-2) Bubbles or blisters due to over-heating |
