  • The structural stress and vibration analysis of the rotary screen are investigated. The mechanical properties of the rotary screen, this is, Young's modulus and density of nickel alloy are determined experimentally. The natural vibration characteristics of the rotary screen are evaluated and the displacement, the stress of the rotary screen under the various load conditions are also examined. The radial displacement of the rotary screen is obtained by experiment under various rotating speeds.

  • The objective of the research is to automate the process of making screen for textile printing. Conventional process give rise to the trouble of high cost, long development period, pollution and etc. The automatized system using laser would give the competitive power for the textile industry by reducing the production cost and period.

  • Electroforming is a kind of metal molding technology. After gilding on the possession object(conductivity, nonconductivity) separate it with possession object and produce a part or duplicate. This process has an excellent ability of duplicating detailed figure. To simplify the manufacturing process of a rotary screen, this study was adopted electroforming technology and produced silicon rubber mandrel. Furthermore, to indicate the optimal condition for the acquisition of high-qualified rotary screen product, the experiment was executed with pH, time, sulfamate nickel solution according to density which were the main factors to decide the condition, then compared it with the product made by original "S" company in Holland. As a result, the figure of hole was more obvious and correct. Also the open size increased by more than 2-3%.
