Maintaining and caring for injection molding machines is crucial for ensuring their long-term stable operation and extending their lifespan. Here are some detailed suggestions for the maintenance and care of injection molding machines:

Routine Maintenance and Upkeep

Cleaning Services

Maintain cleanliness of all parts of the injection molding machine, regularly clean the dust and oil stains from the machine's surface.

Clean molds and hoppers to prevent debris from falling in, ensuring the purity of plastic materials.

Lubrication Maintenance

Ensure regular lubrication of the lubricating components, oiling them 1 to 2 times daily to maintain the unobstructed flow of the lubrication lines.

Regularly inspect and replace lubricating oil to ensure optimal equipment lubrication.

Electrical Inspection

Regularly inspect electrical components for loose wiring and ensure good contact points.

Maintain the cleanliness and dryness of the electrical control box, preventing oil and water from entering.

Temperature Monitoring

Regularly check the oil cooler for proper flow and monitor the oil temperature to ensure it does not exceed the specified limit (e.g., 55°C).

Regular maintenance and care

Hydraulic Oil Management

Regularly inspect the oxidation level of hydraulic oil and proactively replace it. It is typically recommended to clean the oil filter mesh every three months and replace the hydraulic oil and clean the oil tank once a year.

Check the oil level in the fuel tank, promptly replenish hydraulic oil to prevent issues such as increased oil temperature and air solubility due to insufficient oil levels.

Filter Oil Separator Cleaning

Regularly clean the oil filter, maintain the unobstructed flow of the oil suction tube, and inspect the oil filter screen.

Chiller Cleaning

Regularly clean the coolers based on specific conditions to prevent internal blockages. Opt for soft water (mineral-free) for cooling purposes.

Seal Inspection and Replacement

Regularly inspect the pipe retaining nuts for looseness and tighten as necessary.

Inspect high-pressure hoses for any issues and replace them promptly.

Based on the machine's operational status, the sealing elements of the cylinder and piston rod should be replaced every six months to one year.

Electrical Component Maintenance

Regularly inspect the electrical box connections for looseness and tighten as necessary.

When electrical components are damaged, they must be replaced with the original model; no substitutions are allowed.

Maintaining and Caring Instructions

Safe Operation

Always disconnect the power source before performing any maintenance or service work to ensure the equipment is turned off.

Suit up in protective gear to prevent accidental injuries.

Professional Operations

Maintenance and service should be performed by qualified technicians to prevent equipment damage or personal injury caused by improper operation by untrained personnel.

Record and Monitor

Establish and maintain service records, detailing each service's date, content, and replaced parts, etc.

Regular inspections and tests of equipment are conducted to identify and resolve issues promptly.

Replacement Parts

Ensure an adequate stock of spare parts, such as lubricants, hydraulic oils, and seals, for unforeseen needs.

In summary, the maintenance and care of injection molding machines is a comprehensive task that requires the joint efforts of operators and technicians to ensure stable operation and extend the lifespan of the equipment.
