This invention relates to the field of PET hot pressing technology, specifically to a high-precision PET hot pressing molding equipment, comprising an upper shell and a lower shell. Multiple limiting rods are fixedly installed on the top of the lower shell, and limiting plates are slidably installed on the outer walls of the limiting rods. A hydraulic column is fixedly installed on the inner top of the upper shell, and the output end of the hydraulic column is fixedly connected to the outer wall of the limiting plate. A lower mold is installed on the top of the lower shell, and an upper mold is installed on the bottom of the limiting plate. The lower and upper molds cooperate to hot press PET material. A feeding assembly is provided on one side of the lower shell, and a discharging assembly is provided on the other side. A coating assembly is fixedly installed on the outer wall of the lower shell. The coating assembly can apply an anti-sticking agent to the surfaces of the lower and upper molds. The cooperation between the feeding and discharging assemblies can effectively improve production efficiency. The coating assembly can apply the anti-sticking agent to the surfaces of the upper and lower molds to prevent PET material from sticking to the mold surface during hot pressing, thus improving the mold's service life and hot pressing molding efficiency.

The present application provides a kind of aceclofenac enteric microcapsule and its preparation method, the microcapsule includes core and coating, the core includes pill core, aceclofenac, adhesive;The coating includes enteric coating material, plasticizer, anti-adhesive. By screening and optimizing the type and proportion of adhesive and enteric material, optimizing and controlling the preparation process parameters, effectively improve the stability and long-term stability of aceclofenac sustained-release microcapsule, block the release of drug in mouth and stomach, direct the drug to small intestine and slowly release, and the release effect is long-acting and durable.
