For factories that manufacture components and materials, cleaning injection molds and cavities is considered a very important job that factories need to pay attention to. By cleaning injection molds regularly, factories can ensure the quality of the output product is always in the best condition.

In this article, Specco2 will include these content below:

  • The difficulty when cleaning injection mold by the traditional methods
  • Alternative solution
  • Result
  • Best equipment to clean injection mold

Cleaning injection mold with traditional method

In the past, the cleaning of injection molds was often used by factories and product manufacturers with the following methods:

  • Clean with water and scrub, clean by hand
  • Using cleaning chemicals
  • Pressure washer by water
  • Sandblasting
  • Other methods

However, with the above common cleaning methods, the difficulties that manufacturers have to face is those methods can cause production lines to stall and affect business productivity. This included:

  • Cleaning with water will only clean easily accessible surfaces. For small, deep cavities, water can’t be effective enough to clean.
  • The workers will have to proceed to stop production, disassemble injection molds, use cleaning chemicals to clean separately. This will take a lot of time, money, and labor.
  • Pressure washer with water: Some manufacturers will use soap and water to conduct pressure washer. However, this method sometimes will not be able to effectively clean stubborn stains. And may affect injection mold surfaces
  • Sandblasting: With sandblasting, it’s nearly the same with pressure washer with water, it can affect the surface of injection mold, and lower the quality of output products. Besides that, the workers also have to spend time cleaning secondary waste which created from sandblasting

Mold manufacturing companies will usually always ensure that mold maintenance and cleaning are performed regularly and according to a certain procedure. However, with traditional mold cleaning methods, this stage will often take a lot of time for their businesses

In fact, Geiger Group, a corporation specializing in manufacturing and designing molds in the US, said that to clean nearly 100 mold cavities, it took them more than 20 hours with two workers to clean injection mold.

In addition, traditional methods can affect the condition of the mold, thereby reducing the life of the equipment and increasing the cost of replacing damaged materials.

Not stopping there, the mold cleaning phase always requires businesses to stop production, which reduces the factory’s labor productivity. Therefore, choosing an alternative to cleaning molds is a must if manufacturing plants want to ensure operational productivity while maintaining the highest level of product quality.

Alternative solution

For maximum injection mold cleaning while maintaining production capacity, using dry ice blasting machine is a suitable solution. This is a device used to clean the surface of molds and machines. In addition, it can also be used for cleaning automotive parts, cleaning old wall paint, or cleaning factories.

The dry ice cleaning machine uses dry ice at supersonic speed to clean all stains on the surface of the mold. You might need dry ice making machine to help produce this material. Some of the benefits of cleaning molds with a dry ice machine include:

  • Thoroughly clean molds, even stubborn stains. In addition, dry ice blaster can be able to clean small, deep, hard-to-reach mold cavities
  • No secondary waste: After colliding with the surface of the mold, the dry ice will immediately sublimate without leaving any traces, workers only need to clean up the spilled stains on the floor.
  • CO2 dry ice is an extremely safe and non-toxic material like strong cleaning chemicals
  • The dry ice blaster is an environmentally friendly solution because it does not emit CO2 into the environment. CO2 is recycled and reused as efficiently as possible.
  • Ensure health and safety. Keep workers away from hazardous chemicals

In the case of mold cleaning, Specco2 recommends using MicroParticle series machines to be able to clean the smallest details in the mold cavity while ensuring safety, without damaging or scratching the surface. If you compare laser cleaning with dry ice blasting machine, dry ice blasting machine has proven its advantages. This machines also used for cleaning wood of old construction

When using this machine, dry ice will be blasted with sufficient size (about 0.3mm) for maximum cleaning of the surface of the mold and the mold cavity. In addition, these small dry ice particles can pass through sensitive materials such as vents for comprehensive cleaning without affecting the surface of the mold and ensuring output product quality.

After using the dry ice cleaning machine, the Geiger Group says that it has reduced the plastic mold cleaning process from 20 hours to only about 10 hours (up to 50% reduction). Besides, in terms of cost, this company said that it will recover its capital after investing in dry ice cleaning technique in less than 1 year after the labor performance is still guaranteed and the warranty period is maintained. maintenance is reduced, workers can focus on working more effectively.

This corporation gave an employee a  chance to use of the I3 MicroClean dry ice blasting machine. The compact design allows this employee to clean a large number of molds in a short time. In addition, the ergonomic design of this machine and the LED light provide optimal illumination of the surface to be cleaned.
