Gas assisted injection molding is an innovation of the traditional injection molding technology. This advanced technology is to inject inert gas (usually nitrogen) directly into the mold cavity through the segmented pressure control system for plasticization, so that the internal expansion of the plastic parts leads to hollowness, but it still maintains the integrity of the product surface.
Gas assisted injection molding technology is widely used in the injection molding industry. It can be applied to all kinds of plastic products, such as TV or audio shell, various types of plastic boxes and toys, automotive plastic products, kitchen utensils, household appliances and daily necessities, etc.
Compared with simultaneous interpreting, the gas assisted injection molding technology has the following advantages: it can save up to 50% of plastic raw materials. Shorten the product production cycle time; Reduce the clamping pressure of injection molding machine; Reduce the pressure in the cavity, reduce the loss of the mold and improve the working life of the mold, so as to reduce the investment cost of the mold; Reduce the internal stress of the product and solve the problem of shrinkage mark on the surface of the product; Simplify the complicated design of products; Reduce the power consumption of injection molding machine, improve the working life of injection molding machine, reduce production costs.
Bottled nitrogen and liquid nitrogen on the market are expensive and time-consuming, so PSA nitrogen generator is a better choice. PSA nitrogen generator uses inexhaustible air as raw material, carbon molecular sieve as adsorbent, using pressure swing adsorption principle, using carbon molecular sieve to selectively adsorb oxygen and nitrogen to separate nitrogen and oxygen.
Compared with the traditional nitrogen production method, it has the advantages of simple process, high degree of automation, fast gas production (15-30 minutes), low energy consumption, on-line detection of nitrogen purity, convenient operation and maintenance, low operation cost and strong adaptability. PSA nitrogen machine is a permanent investment in gas, a key boot, unattended, can save labor, save costs.
