The development of PVC key chain equipment

Don't underestimate the simple PVC glue products, the history of this kind of glue has gone through several stages before it evolved to the present. Many factories that are used to mechanized processes feel that PVC factories are some of the original production tools. The following will take you to understand the development process of PVC key chain:

At the beginning of production of PVC products, a soft plastic pot was used to fill the color, and then a small needle was installed in the pot, but this method could not make more precise thin strips, and the output value of the product was very low. This method of production is simply not seen now.

In the first two years, air compressors became popular, and the air pressure solenoid valve was used to control the air pressure to advance the syringe and inject the PVC material. Many factories now use this method, of course, this requires the manual operation of key glue skills.

At present, they are relatively high-tech precision dispensers, also known as fully automatic dispensers, which can replace the dispensing process with machines. This method has further promoted the development of the dispensing industry, not only to increase the output value, but also to let The unit price of expensive products has come down.
