Shantou Longsheng Practice: Quick Mold Change for Multi-SKU Orders on One Line

Time: 2026-10-30 10:10:02.280

Fragmented Orders Are the New Normal

Today a converter runs 9 oz juice cups, tomorrow 12 oz bubble tea cups, and the day after a compartment food tray. The competitive edge has shifted from being able to produce to being able to switch. Long changeover times destroy equipment utilization and eat the margin of small orders.

Five Stages That Determine Changeover Time

  • Mold handling: standardized frames and fast clamping structures cut crane and alignment time
  • Heater adjustment: independently controlled heating zones mean a new mold does not start from zero
  • Recipe recall: forming pressure, heating temperature and cycle time stored per product and recalled in one click
  • Material switching: standardized hopper and feeder cleaning prevents cross-contamination
  • First-article confirmation: Longsheng keeps standard parameters and samples for every mold from factory trials, so customers have a benchmark

How Many Molds Per Line

A common rule: duplicate molds for main products, and buy seasonal molds per order. Longsheng precision molds share a unified frame size with the machines, so repeat orders drop straight in.
