Vacuum Positive Negative Pressure Thermoforming Machine

How to properly maintain and maintain the Vacuum Positive Negative Pressure Thermoforming Machine to extend its service life?

Vacuum Positive Negative Pressure Thermoforming Machine is a piece of equipment widely used in plastic packaging, medical equipment, auto parts and other fields. It uses the principles of vacuum and positive and negative pressure to heat and soften the plastic sheet and shape it into the desired shape through a mold. In order to ensure the stable operation of the equipment and extend its service life, it is crucial to carry out correct maintenance and upkeep.

1. Daily maintenance
Cleaning work: Before any cleaning work is carried out, it must be ensured that the equipment is completely de-energized and in a shutdown state. This is to prevent accidental electric shock and ensure operator safety. Prepare the necessary cleaning tools, such as soft cloth, vacuum cleaner, special cleaning agent, etc. Make sure these tools are clean and free of impurities to avoid secondary contamination of the equipment. Operators should wear protective gloves, masks, etc. to prevent dust, chemicals, etc. that may be generated during the cleaning process from causing damage to the skin or respiratory tract. Use a soft cloth to wipe the external surface of the device to remove dust, oil, etc. For stains that are difficult to clean, special detergents can be used for cleaning, but be careful to choose a detergent that will not damage the surface of the equipment. The control panel is the heart of the device and requires special attention to cleaning. Use a dry, soft cloth to gently wipe the control panel; avoid using a wet cloth or chemical cleaners to prevent damage to electronic components.

Lubrication and maintenance: Regularly lubricate the moving parts of the equipment, such as guide rails, bearings, etc., to reduce wear and friction and ensure smooth operation of the equipment. Use special lubricating oil or grease and operate according to the requirements in the equipment instructions.

Electrical system inspection: Before starting the machine every day, check whether the connections of the electrical system are firm and whether the switches and buttons are sensitive and reliable. At the same time, pay attention to observe whether the electrical components have abnormal phenomena such as overheating or scorching, and deal with them in time if any.

2. Periodic maintenance
Heating system maintenance: Conduct a comprehensive inspection of the heating system every month, including the integrity of the heating elements and the uniformity of the heating temperature. If the heating element is found to be damaged or unevenly heated, it should be replaced or adjusted in time.

Vacuum system maintenance: Regularly check the working status of the vacuum pump, including vacuum degree, noise, etc. At the same time, it is necessary to clean up the impurities and accumulated water in the vacuum pipeline to ensure the smooth flow of the vacuum system.

Mold maintenance: The mold is a key component of the thermoforming machine and directly affects product quality. Therefore, the mold should be cleaned and inspected regularly to ensure that its surface is smooth and free of scratches and damage. If necessary, the mold can be polished to restore its surface finish.

3. Precautions
Power outage and shutdown: Before starting cleaning work, make sure that the equipment is completely powered off and is in a shutdown state. This avoids the risk of electric shock and ensures operator safety.

Avoid liquids entering the inside of the device: During the cleaning process, avoid using too much moisture or liquid detergents to prevent liquid from penetrating into the device and causing short circuits or component damage.

Wear protective equipment: When cleaning, you should wear appropriate protective equipment such as gloves, masks, and goggles to prevent irritation or damage to the skin and eyes from chemical cleaners or dust.

Use special cleaners and tools: Choose appropriate cleaners and cleaning tools based on the equipment manufacturer's recommendations. Avoid using cleaners with corrosive or abrasive ingredients that may cause damage to equipment surfaces or components.

Avoid using sharp or rough tools: During the cleaning process, do not use sharp or rough tools to avoid scratching the surface of the device or damaging components.

Thoroughly clean key components: Pay special attention to the cleaning of key components such as heating plates, vacuum chambers, and molds. The cleanliness of these parts directly affects the performance of the equipment and product quality.

Pay attention to cleaning dead corners: Make sure that all corners and hard-to-reach places of the equipment are cleaned to avoid the accumulation of dust and dirt.

Check the cleaning effect: After cleaning is completed, carefully check whether all parts of the equipment are thoroughly cleaned and there is no residue. Pay special attention to checking the cleanliness of key components to ensure they are in good working order.

Record the cleaning situation: record the time, method, cleaning agent used, etc. of each cleaning for subsequent reference and inspection. This helps to track the cleaning status of the equipment and ensure the standardization and continuity of cleaning work.

Avoid frequent cleaning: While it’s important to keep your equipment clean, cleaning it too frequently can also cause unnecessary wear and tear on your equipment. Therefore, the cleaning frequency should be reasonably arranged according to the usage of the equipment and the production environment.

4. Training and guidance
In order to ensure that operators can correctly maintain and maintain equipment, operators should be trained and guided regularly. The training content should include the structure, working principle, daily maintenance methods, periodic maintenance requirements and safe operating procedures of the equipment. Through training, the skill level and safety awareness of operators can be improved to ensure the normal operation of equipment and extend its service life.
