High-value beryllium copper and special alloy steel hot runner manifold for premium auto parts mold of YUDO customized series applies split replaceable tip structured thermocouple to cut long-term maintenance cost greatly compared with traditional integral disposable sensor. Split design divides front sensing measuring tip and rear fixed wire body into two independent detachable assemblies; when front tip is corroded, worn or wrapped by plastic coke after long-term production, maintenance staff only needs to replace low-cost small tip spare part without extracting whole pre-buried wire inside manifold installation hole, avoiding complicated expensive alloy manifold disassembly and precision rework caused by forced extraction of stuck integral thermocouple.
Rear wire part with stable long service lifespan remains fixed permanently and matches multiple batches of new spare tips repeatedly, drastically cutting annual thermocouple procurement fund for molding enterprise. Its only shortcoming is higher initial customized processing cost than standard integral thermocouple, so it is uneconomical to configure split type for low-cost ordinary steel manifold commodity hot runner. Warehouse only stocks cheap spare sensing tips instead of full-set complete thermocouple to save inventory capital occupation and storage space.
