After more than a year's efforts and continuous product improvement, our company's vacuum gun product has finally been successfully developed and obtained a practical patent certificate.

A large number of products have also been exported to Southeast Asia, and the quality has been guaranteed.

What is a practical patent certificate?
Utility model patent is one of the three types of patents (invention, utility model and Design). Utility model refers to a new technical scheme for the shape, structure or combination of products that is suitable for practical use. In the patent law, the requirements for creativity and technical level of utility models are lower than those of invention patents, but they have great practical value. In this sense, utility models are sometimes called small inventions or small patents.

Among the vacuum guns produced worldwide, we may be the only one who has obtained the patent certificate. This is a recognition of our company's technology research and development. Moreover, this technology solves the durability problem of the vacuum gun. A vacuum gun can be used for more than 3 years without problems.
