The only major variable that can affect the forming process is the thickness of the plastic sheet.
Acrylic sheet softening temperature.
Sheet temperature is one of the most critical elements of the thermoforming process.
Acrylic sheets are also available in certain fluorescent colors.
What is the softening temperature of acrylic sheet.
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.
Therefore acrylic is more ideal for most interior and exterior design purposes.
For thicker sheets it will take longer and for thinner sheets it will take less time.
These gases are potentially explosive if allowed to collect in an unventilated area.
To soften acrylic sheet extensive care must be taken about the temperature do not use the standard kitchen oven to soften the acrylic sheet as it could catch fire.
Note the special considerations section for plexiglas mc acrylic sheet on page 9.
Considerable heat can be generated by machining causing stress so it is therefore very important that heat build up is kept to a minimum.
Overhead racks for hanging sheets may be equipped with tracks and trolleys leading to forming equipment to facilitate handling of the sheet.
Temperatures can be off as much as 75 f 42 c possibly allowing the acrylic to overheat.
This article uses a sheet about 1 4 thick so all times are about 10 to 15 minutes per step.
Apply the protective covering.
The forming temperature range is between 290 f and 320 f 143 c and 160 c.
Acrylic is available in sheet stock and round stock making it a good candidate for subtractive machining processes on a mill or lathe.
Acrylic sheets should be hung vertically from racks.
Apply the protective covering on both sides of the acrylic sheet and the area that needs to be softened.
As the temperature is increased the sheet passes through the thermoelastic state to the thermoplastic state.
A wide variety of colors are usually available.
How do i clean acrylic.
Most kitchen ovens do not have accurate temperature control.
While acrylic softens at higher temperatures it does not actually melt until it reaches 320 f 160 c.
Acrylite ff sheet will soften as the temperature is increased above 195 f 91 c.
Modify the timing as necessary.
Clear plastic can refer to a wide range of synthetic compounds with varying strengths melting points and other properties.
Acrylic sheets give off highly flammable fumes when decomposed overheating.
The change is gradual rather than sharply defined.
