Patch production line

Traditional plasters are classified into solvent method (rubber + gasoline), hot pressing method (rubber + litho powder), and hot melt adhesive method (hot melt adhesive) according to the process. On the basis of fully absorbing various traditional manufacturing processes, we have integrated the advantages of a variety of traditional processes, made up for many shortcomings of traditional processes, and created a unique production process with independent intellectual property rights. The products produced are of stable quality and excellent properties.


After years of foreign trade export verification, it has been widely praised by exporting countries and regions.

The original plaster production process with independent intellectual property rights:

Plaster is a traditional dosage form in China. After years of development, although it has evolved from traditional manual cooking to the current industrial production, the industry as a whole still remains in a situation of outdated equipment and backward technology. Instead, the production level of modern plaster is in Taiwan, South Korea and Japan have been greatly developed. At present, the products of the above three regions are basically recognized internationally, especially in developed countries, such as Japanese Hisamitsu’s Salombas plaster.


The founder of Hao Aiyou has more than 20 years of experience in plaster research and development and production. Through investigation and comparison of many internationally advanced plaster patch production lines in Taiwan, South Korea, Japan, etc., he independently developed and customized a set of leading domestic new production lines. The equipment can be on par with the world's top plaster manufacturers, and with the unique production process independently researched and developed, the technological innovation and comprehensive quality of our products are in a leading position in the domestic industry.

  • Traditional plasters are classified into the solvent method (rubber + gasoline),  Solvent method, high temperature causes the loss and damage of active ingredients, the production process is easy to pollute and not environmentally friendly
  • hot pressing method (rubber + lithopone), Hot pressing method, the molecular structure of the paste is unstable and easy to deteriorate, and the gloss of the paste surface is not enough
  • hot melt adhesive method (hot melt adhesive), Hot-melt adhesive method, the cheapest plaster solution, mostly used in low-end products, the safety of hot-melt adhesive has not been demonstrated

The products produced are of stable quality and excellent properties. . After years of foreign trade export verification, it has won wide acclaim from exporting countries and regions.
