| Summary: | 碩士 === 建國科技大學 === 自動化工程系暨機電光系統研究所 === 100 === Human civilization began in stone, wood era, and then progress to the
use of iron, copper and other metals, then a striking progress in the
invention of glass and other metals, until the emergence of plastic materials.
Plastic is a panacea, it was once said, "The twentieth century is the century
of plastic, plastic is an integral part of our daily lives that it has integrated
into all aspects of food, clothing, shelter, education, music, new plastic era
is finally coming to the Ting students, scientists continue to research and
development, the plastic can be used in high-tech products.
The purpose of this paper the design is the plastic material instead of
iron, so let the industry reduce the cost of increased market
competitiveness, design products will be plastic injection molding hardness
and strength of the main demands of the product quantify enough to
compete with the iron material , long-term use can make the product under
the color of the same, do not iron materials rust affect the quality, indeed
the paper designs the actual promotion of chairs round the
commercialization of plastic products and there is considerable market
competitiveness.
