A-type arc forming device and angle forming device are ideal choices for making signs with acrylic acid and other materials. These two types of equipment are based on the previous generation of hot bending tools, and have been innovated and upgraded with PTC heating components to ensure safety, better heating efficiency, lower energy consumption, faster heating and longer service life. The heating temperature is automatically controlled, saving the trouble of turning any thermostat, so it is very easy to use. The heat conduction aluminum plate ensures the uniform and stable heating of the processing materials and the proper contact between the materials and the heating plate. Plastic materials with a thickness of 1.5mmdash4mm can be processed by this equipment, which will not produce smoke or steam while heating and softening very quickly The heating plate is oxidized and will not stick to the processing materials. The equipment also has a simple and easy to use design, and the shell is made of heat resistant ABS. The bottom, edge and heating plate of the heating part are flat and even, so the equipment can directly handle the plate with the maximum width of nearly 100mm.
