Product application: Metal mold heating tubes have the advantages of high heat generation, small size, high temperature resistance, high precision, and fast heating speed. They are widely used for heating metal templates, such as packaging machinery, plastic machinery, hot stamping forming equipment, automated welding equipment, etc. In order to facilitate temperature detection, overheating protection, and extend the service life of the heating tube, temperature measuring thermocouples can be integrated into the interior of the heating tube for superior performance. Fixed methods such as flange plates and threads can be used. Design and production parameters: outer tube diameter: Φ 3~Φ 32, production length: 20-2000mm, length error ± 1mm
