Why should overseas buyers keep heating elements and sensors in stock?
• Heating elements are wear parts; heat-seal jaws oxidize at high temp, life 3-6 months, no stock means downtime.
• Sensor (thermocouple/PT100) drift causes heat-seal temperature runaway and higher reject rate; keep 1-2 sets.
• Overseas lead time is often 4-8 weeks plus customs clearance; downtime cost far exceeds spare parts cost.
• Heating element wattage/size varies by model; verify voltage, wattage, thread per BOM before stocking.
• Keep 20%-30% of annual usage as safety stock, including thermocouples and solid-state relays.
