Plastic mold industry, the vast majority are small and medium enterprises as well as micro-enterprises brick mold, they are in the manufacture of plastic mold products manufacturing companies, and manufacturing of mold products to middle and low in the majority. In the middle and low mold overcapacity and lower margins endlessly decline, many companies are increasingly difficult to maintain brick mold, so each find a way. Expand high-grade plastic mold products, plastic mold products to improve the technical content and added value is a sure way I all agree; expands to the center of the mold, dirty-related products is a way; and the development of modern manufacturing services is a species approach has broad prospects. The plastic mold manufacturing enterprises to the "Product + Services" as the subject, the integration of two service-oriented manufacturing enterprises shift to service-oriented manufacturing, so that enterprises from profit-oriented kind of products to serve the profitability of the main changes to green brick mold, which not only to get rid of the current predicament and to enhance the level required, and for a long period of time will always be an important direction of industrial transformation and upgrading of the way. Important ways and means of plastic mold is to upgrade and develop new markets, enhance core competitiveness. Ultrasonic polishing the workpiece into the abrasive suspension and placed in an ultrasonic field together, relying on the role of the ultrasonic oscillation, so that the abrasive on the workpiece surface grinding and polishing. Ultrasonic machining macroscopic force is small, does not cause deformation of the workpiece brick mold, but the tooling fabrication and installation more difficult. Ultrasonic machining may be combined with a chemical or electrochemical method. In the etching solution, on the basis of the electrolysis, the solution was stirred and then ultrasonic vibration is applied, so that the surface from the lysate, corrosion or electrolyte near the surface uniformly; ultrasonic cavitation in the liquid is also capable of inhibiting the corrosion process, in favor of surface brightness.
