Suggestions for processing improvement of Neoprene Zipper Cable Sleeve

1. Welding quality

During the welding process, the reinforcing ring and the steel wire mesh sleeve are prone to false welding of the steel wire (overheated or not welded). When the hose is installed in the pipeline, due to the uneven force on the steel wire, under the action of the medium pressure, the false welded steel wire pulls Taking it off may cause damage to the outer bulge of the Open Type Braided Sleeve.

The longitudinal weld of the Open Type Braided Sleeve in the Neoprene Zipper Cable Sleeve has defects such as false welding, pores, loose dendrites, which reduces the effective area of the Open Type Braided Sleeve wall thickness, and the insufficient strength leads to cracking and damage at the weld. The welding of carbon steel materials and stainless steel parts creates a typical unfavorable environment where a small area of male parts and a large area of female parts are in contact, which can easily lead to rapid corrosion and failure of the material. Therefore, we should strengthen welding process research and welding material selection, and strengthen welding quality inspection to improve product reliability.
2. Mechanical processing
Due to uneven stress during the corrugation process, the material is prone to regular micro-cracks on the inner surface of the wave peak. During the welding and forming process, micro-cracks originate on the inner surface of the hose. During the subsequent assembly test And during use, microcracks will cause fatigue expansion and then fail. Improvements in material processing and welding processes can avoid the occurrence of microcracks.
3. Heat treatment
The main functions of heat treatment for Neoprene Zipper Cable Sleeve are: improving the cutting performance and processing accuracy of metal materials; improving the fracture toughness of metal materials; and reducing cracking of metal materials. If the heat treatment is incomplete, product quality will be affected.
