1. Manual cleaning:
In this method, injection moulds are cleaned manually using solvents and detergents. Solvents help to loosen and remove dirt, grease and residue from the surface of the mould. This involves scrubbing the mould with a brush, sponge or cloth to ensure thorough cleaning. However, manual cleaning can be time and labour intensive.
2. Ultrasonic cleaning:
Ultrasonic cleaning uses high-frequency sound waves to agitate the cleaning solution, creating tiny bubbles that effectively remove contaminants from the mould surface. It is a non-abrasive method, especially suitable for cleaning complex and hard-to-reach areas on the mould. Ultrasonic cleaning is fast and efficient with high cleanliness.
3. High-pressure water cleaning:
In this method, high pressure water jets are used to remove dirt, debris and other contaminants from injection moulds. The impulse of the water helps to dislodge the particles and ensures thorough cleaning. It is particularly effective in removing large or stubborn contaminants from the surface of the mould. However, care must be taken not to damage the mould surface by the force of the water.
4. Laser cleaning:
Laser cleaners are becoming increasingly popular for cleaning injection moulds. This method uses a high-energy laser beam to vaporise dirt, grease and other contaminants on the mould surface without causing any damage. Laser cleaning is a non-contact, environmentally friendly method that effectively removes even the smallest particles. It is particularly suitable for cleaning precision moulds or moulds with complex geometries.
In conclusion, cleaning injection moulds is essential to maintain their performance and extend their service life. The choice of cleaning method depends on factors such as the type of contaminant, the mould material and the complexity of the mould. Whether it is manual cleaning, ultrasonic cleaning, high-pressure water cleaning, or the use of a laser cleaner, regular and proper cleaning ensures optimum performance and productivity of the mould.
