Step 1
Strip heater
Answer
A strip heater is a device designed to form straight or small curved bends in thermoplastic sheet materials. It operates by utilizing an electric element that generates heat, which is enclosed in a channel with an opening at the top. This channel accommodates the thermoplastic sheet, allowing for precise heating.
Operating Features
- Heating Mechanism: The heating element is activated, leading to the heat transfer into the strip. The temperature can be controlled by adjusting the electric current.
- Adjustment of Width: The width of the strip to be heated can be altered by adjusting the supports across the opening, enabling versatility in processing materials of different widths.
- Bending Capability: When heated to the correct temperature, the material can be bent to the desired shape. A higher bend radius requires more careful control of the heating temperature, ensuring uniform heating to prevent material damage.
- Thermostatic Control: The strip heater may include a thermostatic control system, allowing for accurate temperature management, essential for efficient operation.
