Split replaceable tip thermocouple divides front sensing tip and rear fixed wire body into two separable assemblies for high-cost beryllium copper alloy manifold hot runner of YUDO customized project, and scientific lean inventory classification can greatly reduce warehouse idle capital occupation compared with stocking full-set integral thermocouple. According to component failure law, front small measuring tip bears direct high-temperature contact and corrosive plastic gas erosion, belonging to fast-wearing vulnerable spare part with short average service cycle, while rear embedded wire body is protected inside mounting hole with low damage probability and long service life. Therefore warehouse only establishes regular circulating safety stock for various specification spare tips, cancel bulk full-set thermocouple inventory to save storage space and cut large idle procurement fund occupied by slow-moving rear wire body stock.
Set dynamic safety stock threshold of spare tips based on historical monthly replacement statistical data of corresponding production line: when remaining inventory drops below lower limit value automatically trigger supplementary purchasing application, avoid stock-out emergency rush purchase with high unit price meanwhile prevent overstock surplus capital waste. Classify spare tips by manifold installation thread specification, sheath diameter and working temperature grade with independent label coding to avoid picking error during urgent maintenance.
Annual hot runner overhaul counts actual tip consumption data of each mold project, adjust next year's safety stock quota dynamically according to production order change and raw material formulation adjustment; for newly introduced high-corrosion recycled plastic production line appropriately raise corresponding tip inventory reserve coefficient in advance to cope with accelerated wear speed caused by harsh working condition. This refined inventory mode has become core lean cost control measure for large-scale mold workshop equipped with numerous high-value alloy hot runner manifolds.
