Or do i need to have a two part mold with a top and a bottom.
Bending abs plastic sheet with heat gun.
Forming a radius can also be done by using a heat gun using a back and forth motion across the length of the sheet both top and bottom until the material is soft enough to start bending.
The only absolute requirement for bending and forming kydex is heating the sheet until soft when the material becomes formable.
The spec sheet shows a temperature of 234 degrees.
The only major variable that can affect the forming process is the thickness of the plastic sheet.
Keep the gun at a distance of at least 8 to 12 do not get the heat too close to the material as blistering may occur.
Bending shaping plastic with hot air gun heat gun.
When the texture of the abs changes slowly push the abs down.
Modify the timing as necessary.
Tutorial for how to.
Preparing hot air gun w.
Only part of the shape is forming.
I have a wooden form and a piece abs plastic that i laid on top of the form.
Kydex can be easily cut to size by scoring and cutting sheets with a razor or similar knife.
This is my first attempt at oven forming abs plastic.
Strong reusable our sheets can be re melted again and again so you can build reshape and add to your work as often as needed.
Cut out different shapes from the sheet.
Ideal for perspex acrylic plexiglass polycarbonate.
For thicker sheets it will take longer and for thinner sheets it will take less time.
Because plastic has a rather low thermal conductivity it takes a surprisingly long time to both heat up and cool down very easy to light the surface on fire while 1 8th inch below is still cold.
Heat create melt our plastic sheets with heat gun 150f and mold to any shape you like by using your hands or using tools.
Is there a problem with going higher.
To create bends for small scale projects in plexiglass perspex or acrylic 1 8 inch and thinner you can use a small torch butane kitchen torches work well a paint stripping heat gun or an embossing heat tool which is a wand that works very similarly to a paint stripping gun but using a smaller more directed heat flow with a smaller fan.
If you wait long enough it will bend along the table or foam.
1 2 inch radius should be pretty easy.
Heat it up with a heat gun.
I have the oven set at 250f.
This article uses a sheet about 1 4 thick so all times are about 10 to 15 minutes per step.
If you re impatient you can also bend it yourself.
