What accounts for the majority in air duct processing?

大部分是現在吵得沸沸揚揚的數螺旋風管了吧。在螺旋風管其長度等方面是要好于矩形風管：這是由于普通的螺旋風管，其正常長度是為3米到6米，而矩形風管其是為1米到1.5米，除此之外，螺旋風管的長度，還能夠依照具體需求來定做，從其它方面來看，螺旋風管中的連接點，是能夠很大程度上根絕的，由于其風管之間的連接，只用管接件，而矩形風管則需求雙法蘭體系。

Most of them are now noisy spiral tubes. The length of spiral air duct is better than that of rectangular air duct. This is because the normal length of ordinary spiral air duct is 3m to 6m, while that of rectangular air duct is 1m to 1.5m. In addition, the length of spiral air duct can be customized according to specific requirements. From other aspects, the connection points in spiral air duct can be eliminated to a great extent. Because the connection between air ducts, only pipe connectors are used, Rectangular duct requires double flange system.

相對于螺旋風管其出產制作能夠獲取批量化制作嗎?

Compared with spiral duct, can it be produced in batches?

這個話，對螺旋風管是毫無其它疑問的，由于從如今來看，該風管的制作，已經獲取了體系化和智能化，并且在質量控制上，也能夠做到非常好，因而獲取批量化制作，是毫無疑問的，還能夠做到有好的產品質量。

There is no doubt about the spiral air duct. From now on, the production of the air duct has been systematized and intelligent, and the quality control can be very good. Therefore, there is no doubt that the mass production can be achieved, and the product quality can be good.

在咬口成型技術上，螺旋風管，是運用了怎樣的技術：

In terms of bite forming technology, what kind of technology is used for spiral air duct:

螺旋風管的咬口成型技術，關鍵的是運用模具來進行完成的，由于其限制模具表面能夠長時間保持不變，因而大大增長了風管的運用年限，并且，在其密封性能、連接強度與咬口緊密度上，也是有好的表現的。

The key to the biting forming technology of spiral air duct is to use the mold. Because it restricts the mold surface to remain unchanged for a long time, it greatly increases the service life of the air duct, and also has good performance in its sealing performance, connection strength and biting tightness.
