The advantages of oil-free vacuum pumps in industrial processes
Manufacturers in all major areas are always looking for ways to increase profitability - the goal is to improve process efficiency without compromising quality and safety. This article introduces you to the dry vacuum pump technology that was originally used in the semiconductor industry. It started to move to industrial and laboratory vacuum processes because of its clean and efficient operation. The key to successfully replacing existing oil-based vacuum pump systems is to find the most suitable solution for a particular application. To see the different types of applications that can benefit, here are four different industrial processes and what are the main benefits of using dry vacuum pumps.

this machine is a perfect and ideal one for making flat paper handles, which can do the job from making flat Paper Rope, doing the embossing on the rope, putting hot glue on the rope and paper strap, folding the handle rope in right angle, forming the flat handle, cutting the handle into requested size to putting the cold glue on the ready made Paper Handle at one time. This machine can be connected with production line at the end of the machine to form a complete production unit.

The dry vacuum pump gives the working volume no oil and therefore brings many benefits. First, it enhances the reliability of the pump. Dry pumps are not affected by water vapor or dust particles like oil-sealed pumps, so they are more durable and require less maintenance. Reducing the amount of oil used also means reducing the cost of carefully treating the oil. The use of a dry vacuum pump also minimizes possible contamination. This contamination can occur both in the oil and affect the performance of the pump, as well as in some extreme situations, such as in the final product. 
Rolling spray repair
Metal spray coating is a long-established process in the rolling spray industry and uses thermal evaporation techniques in a vacuum environment. A thin layer of metal, most commonly aluminum, adheres to paper, polyethylene (PE), or other polymer films, creating a strong, attractive packaging that protects against moisture, dust and light. . This is an ideal material for food applications because it keeps the product fresh and extends its shelf life. This process is also increasingly used to produce decorative papers, gift wraps and films.
A large reel (up to 2 meters wide) with a backing material (paper or PE film) was used in the process and they were safely placed in the winding chamber. These reels rotate continuously - allowing the substrate material to pass through the diaphragm at high speed into the spray booth (Figure 1). The spray booth requires a very high vacuum, between 10-4 and 10-5 mbar, and the winding chamber can maintain a low vacuum, approximately 10-2 mbar. Spraying is the result of a thermal evaporation process in which the metal is heated so that it vaporizes and then deposits on the substrate material.
