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.

氣體輔助注塑技術(shù)在注塑行業(yè)中備受廣泛應(yīng)用，可應(yīng)用于各種塑膠產(chǎn)品上，例如電視機(jī)或音響外殼、各類型塑膠盒和玩具、汽車塑料產(chǎn)品、櫥具、家庭電器和日常用品等等。

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.

同傳統(tǒng)注射成型工藝相比，氣體輔助注塑技術(shù)具有以下優(yōu)點(diǎn):可節(jié)省高達(dá)50%塑膠原料；縮短產(chǎn)品生產(chǎn)周期時(shí)間；降低注塑機(jī)的鎖模壓力；降低模腔內(nèi)的壓力，減少模具的損耗和提高模具的工作壽命，從而降低模具的投資成本；降低產(chǎn)品的內(nèi)應(yīng)力，解決產(chǎn)品表面縮痕的問(wèn)題；簡(jiǎn)化產(chǎn)品繁瑣的設(shè)計(jì)；降低注塑機(jī)的耗電量，提高注塑機(jī)的工作壽命，降低生產(chǎn)成本。

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.

市面上的瓶裝氮?dú)夂鸵旱急容^昂貴且費(fèi)心費(fèi)力費(fèi)時(shí)，使用PSA制氮機(jī)是比較好的選擇。PSA制氮機(jī)以取之不竭用之不盡的空氣為原料，以碳分子篩作為吸附劑，運(yùn)用變壓吸附原理，利用碳分子篩對(duì)氧和氮的選擇性吸附而使氮和氧分離。

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.

與傳統(tǒng)制氮法相比，它具有工藝流程簡(jiǎn)單、自動(dòng)化程度高、產(chǎn)氣快(15～30分鐘)、能耗低、氮?dú)饧兌仍诰€檢測(cè)，操作維護(hù)方便、運(yùn)行成本較低、裝置適應(yīng)性較強(qiáng)等特點(diǎn)。PSA制氮機(jī)是一次投資用氣，一鍵開(kāi)機(jī)，實(shí)現(xiàn)無(wú)人職守，可以節(jié)省人工，節(jié)省成本。

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.
