GAS SUPPLYING APPARATUS FOR FABRICATING FOAM PLASTIC

摘要

PURPOSE: A gas supplying apparatus is provided to precisely form an outer appearance of an article by preventing a gas trace from being created on the outer appearance of the article. CONSTITUTION: A gas supplying apparatus includes a gas tank(2) for storing high-pressure gas. A gas compressor(4) is provided to boost gas pressure stored in the gas tank(2). A foam gas tank(8) stores boosted gas in order to supply boosted gas into a press(10) at a constant speed. A pressure-control gas tank(6) is connected to the gas compressor(4) so as to control gas pressure. The gas tank(2) is connected to the gas compressor(4) through the first supplying pipe(12), the gas compressor(4) is connected to the foam gas tank(8) through the second supplying pipe(14), and the gas compressor(4) is connected to the pressure-control gas tank(6) through the third supplying pipe(16).
