A Study on the Improvement of Processing in Telephone Dial through Industrial Engineering Technique

As the result of processing improvement of Telephone Dial by substituting. Synthetic Resin for metalic materials, improved characteristics of quality can be gained as follow. 1. By the improvement of structure and assembling of the Telephone Dial, the complex process of manufacture can be a simplified one, and at the same time the working process can be done in the form of assembly. 2. In the efficiency test of the Telephone Dial, the noise decreases by 5% compared with the first test. In the test of life and environment, it accords with the standard of the Ministry of Communications and its function betters. 3. By using synthetic resins instead of metalic materials the cost can be reduced by \340 than the first improvement and it also brings the heightend value.
