I. Standard Repair Cycle
Basic restore Scenario: It is sufficient to unblock and remove the hot runner, restore the mould core through welding, and bore and insert the mounting holes. There is a comprehensive repair cycle of 7-10 days.
Complex Repair Scenario: Necessitates the re-adjustment of thermal expansion clearances, the correction of overall form and position tolerances of the mould plate, and the creation of custom-machined mould cores. The repair process typically lasts between 10 and 15 days.
II. Critical Factors Influencing the Repair Cycle
Spare Parts Inventory: The repair cycle can be reduced to 3-5 days by directly replacing spare mould cores of the same model that are available in advance.
Machining Resource Priority: The standard repair cycle can be reduced by approximately 30% if 24-hour continuous work is arranged.
Mould Size Complexity: The repair cycle for large automotive moulds will be 2-3 days lengthier than that for small electronic moulds.
III. Reference and Comparison The typical production cycle for a hot runner mould that is entirely new and complex, and meets the same specifications, is 50-70 days. The production line downtime is considerably reduced by the fact that the repair cycle for a level-four locked mould is only 1/5 to 1/3 of the new mould production cycle.
This repair cycle is specifically designed to accommodate the actual operation and maintenance scenarios of precision injection moulding production lines and can be utilised in advance for the purpose of reference in production scheduling and order delivery scheduling.
