Q: How to blow the acrylic board into a hemisphere？
A: Acrylic hemispherical blow molding is the production process from
acrylic sheet to molding, this needs to be done by the mold. Then you need enough air pressure to put the acrylic in the oven and
then put it on the mold. The mold needs to be sealed
and then blown through the air gun to make it swell. The height of the
control hemisphere is equivalent to the diameter, and can form a hemispherical
cover.
The blow-up program has high requirements on the experience of the
master computer. The following Responsy explains the steps of the acrylic
hemisphere production for you:
1. Cut out the acrylic board first.
2. Before blow molding, fix the blow mold
first. The operator must adjust the level and vertical position of the mold so
that the center point of the acrylic hemisphere can be ensured. The acrylic
plate is then heated and placed on a blow molding machine, which is firmly
fixed.
3. Air guns are used to blow air. Acrylic slowly
expands and forms. When the top of the ball is about to touch the scale, stop
blowing.
4. Cut off the tooth prints left by the fixed
position, the acrylic hemispheres are made.
