Spring Festival holiday is approaching, and many companies are starting to grant early annual leave. When an injection molding machine needs to be shut down for an extended period, here are some details to pay attention to in terms of maintenance:

1. Cleaning and Maintenance

• Clean all internal and external surfaces, remove waste and residue to prevent contamination and corrosion caused by prolonged accumulation.

• Apply anti-rust treatment to metal surfaces and coat them with rust-preventive oil to prevent surface rust and corrosion during extended equipment downtime.

• Inspect lubrication points and replace lubricating oil to ensure that lubrication is maintained even after long periods of inactivity, preventing rust or wear on components such as bearings.

• Fill the material pipe with purging compound to prevent oxidation and rusting of the screw and material pipe during extended periods of inactivity.

2. Mold and Cooling System

• Thoroughly clean the mold, including mold cavities and cooling channels, to prevent plastic residue from causing contamination and blockages.

• Clean and drain the cooling system to ensure that a clean cooling system does not result in corrosion or scaling during downtime.

• Drain the cooling water system to prevent pipe bursts due to low temperatures.

3.Electrical Components

• Turn off the main power to ensure that the equipment is completely powered down, preventing prolonged standby power consumption or potential safety hazards. Regularly inspect the electrical components.

4. Periodic Inspection

• Turn off the main power supply and ensure that the device is completely powered off to avoid long-term standby consumption of power or potential safety hazards. Regular inspection 4. Electrical parts

5. Regular Inspection

• Conduct regular inspections of the equipment's wiring terminals and the insulation status of electrical components. Before applying power after extended downtime, perform thorough checks to prevent damage or risks arising from electrical faults.

Through meticulous shutdown maintenance and care, injection molding machine equipment can be effectively protected, preventing equipment aging and failures caused by prolonged downtime. This approach extends the equipment's lifespan, ensuring that it operates smoothly when reintroduced into production.
