  In the rubber and silicone industries, it has always been a headache to remove dirt from molds. Since vulcanized rubber and silicone need to be carried out at high temperatures, some oils and chemicals left in the molds need to form stubborn dirt after coking at high temperatures for a long time. Existing mold cleaning methods are as follows:

  1. Dry ice cleaning:

  Dry ice cleaning molds have zero damage to the cleaning molds, medium efficiency, high cost of dry ice, not easy to store, dangerous goods, and cost reduction methods. Only by purchasing dry ice locally can we reduce costs, because purchasing dry ice in other places will consume dry ice during transportation and increase costs.

  2. Chemical cleaning:

  Chemical cleaning of molds will corrode the metal material on the surface of the mold, and cleaning requires soaking for a period of time to increase the corrosion of the mold, which is not conducive to long-term use of the cleaning mold, and will generate industrial wastewater, which is harmful to human health.

  3. Sandblasting cleaning:

  The sandblasting cleaning mold uses spraying materials (copper sand, quartz sand, emery, iron sand, sea sand) to spray onto the mold surface at high speed, which will cause damage to the mold surface and is not conducive to long-term use of the cleaning mold, causing air pollution and noise, and generating inhalable particles that can cause harm to the human body.

  4 Laser cleaning:

  Laser cleaning molds are non-contact and non-abrasive, suitable for various molds, pollution-free, high upfront investment, but the cleaning system can be used stably for a long time and has low operating costs.

  Laser cleaning of molds uses the characteristics of high brightness and small divergence angle of the laser to concentrate the laser beam with sufficient power and irradiate it to the appropriate location. The material absorbs light energy and converts it into heat energy, which generates a series of physical and chemical processes to remove surface contaminants.

  The laser cleaning machine is suitable for cleaning various molds, such as tire molds, rubber molds, injection molds, glass bottle molds, and so on.

  Laser cleaning machine is a high-tech product that represents the new surface, easy to install, control and automate. Simple operation, power on, turn on the equipment, you can clean without chemical reagents, no media, no dust, no water, can automatically focus, fit the curved surface cleaning, cleaning the surface cleanliness advantages, can remove the surface of the object resin, oil, stains, dirt, embroidery, coating, coating, paint.
