There are several ways to bend plastic. The most optimal one, which allows you not to break the material and make a bend at the right angle, is to use a molding machine.
Necessary
- - molding machine;
- - silicone;
- - MDF board;
- - industrial hair dryer.
Instructions
Step 1
If you need to bend plexiglass or polystyrene, prepare a few fixtures. Make a wood fiber board (MDF) mandrel. Assemble the mold, and, depending on the length and width of the plastic part, adjust it to the desired size. Go over the entire surface with sandpaper so that there are no distortions.
Step 2
Make a shell for the plastic part from silicone on a molding machine. It is necessary to fix the flat workpiece on the mandrel and keep its surface from chips and scratches.
Step 3
Insert the original flat plastic part into the shell and secure it in the MDF mandrel. Place on molding machine. The unit will heat up, and the plastic will begin to settle on the mandrel, taking the desired shape. Wait five to seven minutes. With gloved hands, carefully remove the finished part from the machine. Place on a metal surface to cool the material. Remove the mandrel.
Step 4
Bending a plastic pipe is even easier. Get a gas burner or industrial hair dryer. Turn on and hover over the place where you plan to fold. The distance from the heating device to the surface of the part must be at least five centimeters. Rotate the pipe without stopping, otherwise it will catch fire. Heat until material is soft. Bend. Hold the pipe in this position for a while so that the plastic hardens.
Step 5
Plastic foamed PVC wall or window slopes can be bent to the desired angle, making frequent cuts along the radius. After creating the desired shape, they are fixed with special glue. This allows parts with extensions and bends to be produced.
