Hot Chamber Die Casting Machine Periodic Maintenance Guide

Proper maintenance is essential for maximizing the performance and service life of your die casting equipment.It can help operators maintain equipment stability and production safety. By following these recommended practices, manufacturers can significantly reduce unplanned downtime and maintain consistent production quality.

Safety System Verification

To ensure safe operation of the die casting machine, regular inspection of key safety components including emergency stop buttons, safety doors, grounding lines, protective devices and locking screws is recommended. Emergency stop tests should be performed monthly to ensure immediate power cutoff upon activation; safety doors require bi-weekly verification of their mold clamping interruption function in both manual/automatic modes; grounding and protective devices should be checked monthly, with locking screws tightened quarterly. 

Hydraulic System Maintenance

Hydraulic systems require the use of approved hydraulic oil every six months, with strict prohibition of mixing new and old oil; monthly inspections should include checking oil pump pressure and abnormal noises, cleaning filter elements, and examining oil lines and connectors for leaks; all cylinder assemblies must be disassembled, cleaned annually, and worn parts replaced. All operations must comply with the equipment manufacturer’s technical specifications.

Structural Frame & Lubrication System Periodic Maintenance

The structural frame requires monthly removal of external debris (key areas include material cylinder inlet, limit switches, crank arm lubrication points, and template T-slots),with monthly inspections should include verifying motor air vent clearance, clamping frame fastening screws, and lubricating oil pump pressure; quarterly checks of clamping frame operation ensure no jumping or swaying; all grease nipples require lubrication every six months; annual verification of machine frame level is essential. All operations must comply with equipment manufacturer’s technical specifications.

 Cooling System Maintenance

The cooling system requires water quality testing and use of purified freshwater every six months, along with cleaning heat exchanger scale and verifying injection unit and nozzle cylinder line clearance; quarterly maintenance includes cleaning cooling tower filters and verifying servo cooling motor rotation and backpressure.

Furnace System Periodic Maintenance 

The furnace system requires monthly inspection of terminal connections: resistance furnaces need measurement of heating element resistance and grounding integrity, while induction furnaces require verification of cooling fan operation and cleaning of ventilation pathways; every six months, inspect the condition of refractory bricks/wool and exhaust ports, while calibrating thermostat switching functionality and temperature control accuracy.
