Measure the inside of your oven.
Bending abs plastic sheet.
Bending polycarbonate sheet with a heat gun.
If the form is cool that will make it diffucult to pull the plastic into the details of the form.
To bend abs lay the piece on the edge of a table or the foam part and heat up the part where it needs to bend.
Heat source small projects with bends that are close together will need upon heat source which can be easily aimed at small areas.
First experiment with a few scraps to get the time and heat right.
If you want to lay it on the form in the oven it might be wise to preheat the form first then lay the abs on it then put it back in for time enough to heat the plastic.
Only that the operator is now forced to move the heat gun constantly along the bend line and flip over the polycarbonate sheet to ensure both sides get heated.
For example let s use 0 250 in.
If you wait long enough it will bend along the table or foam.
When the texture of the abs changes slowly push the abs down.
Sheet surface temperature will directly correspond to material gage.
Have a mold ready to use.
You can see this in the video below.
To achieve this core temperature the former must calculate the temperature differential on both sheet surfaces.
Make adjustments appropriate to the specifications of your project.
High density polyethylene hdpe which requires a core temperature of approximately 280 f for optimal forming.
Slip the kevlar on and position the assebly on your choice of straight surfaces energize place plastic on element and wait till bercomes taffy like and make your bend.
Position a strip heater at the recommended safe distance from the plastic as directed by the manufacturer.
To bend sheet plastic and acrylic you will need.
Position the plastic sheet so that the area you will bend is between two flat flame retardant surfaces like saw horses.
The example here is the outside of a mold but it can work inside too.
Put on cotton safety gloves.
As you ll need to put the plastic sheet into the oven this is your size limitation.
I have foung that simle carpeners square will damn close 90 degree.
