Slow Mold Replacement on Production Lines? Standard Process Improves Maintenance of Chocolate Packing Machines

Chocolate packing machines are core equipment for confectionery factories. Most traditional workshops adopt irregular manual operations for mold disassembly and installation. Without unified operating standards, workers often spend extra time on mold replacement during product switching. Random tightening of bolts and improper handling may also cause mold damage or positioning errors, which directly affect the overall operating rate of automatic production lines. This problem is more prominent in factories that produce multiple types of chocolate products and need frequent mold changes every day.

The industry has formed a set of universal operating standards for chocolate packing machines. Operators must implement LOTO safety procedures to cut off power and air supply first. For heat-sealing molds, wait until the surface temperature drops below 40℃ before operation. Three core modules, including the transfer wheel, the folding former, and the cutting die, shall be disassembled in a fixed order.

When installing molds, use locating pins and reference holes for positioning. All locking bolts shall be fastened diagonally with a torque of 18~22 N·m to avoid unbalanced stress. After assembly, manually jog the machine for three full cycles to check for jamming or abnormal friction.

This standardized process is compatible with mainstream European and domestic chocolate wrapping and foil packaging machines. It unifies operating standards for different staff and reduces human errors caused by irregular operations. It requires no modification to the original equipment structure and is suitable for small and medium-sized workshops as well as large-scale mass production factories. It effectively adapts to the high-frequency switching demand of modern food production lines.
