Now more and more insulating glass are filled with argon gas in buildingconstructions and doors &windows.In the process of filling argon gas,thepressure generated during the gas replacement process directly reflects onthe aluminum spacer.Once there is a weak or missed welding,the accidentalrate during the processing of the insulating glass will be greatly increased.Now our technical team has made further improvements on the basis of ourexclusive patented seamless welding aluminum spacer bar.First of all,wechanged the welding from the back of the aluminum spacer to the front.During the processing of insulating glass unit,the accident of weldingbreakage due to insufficient pressure on the aluminum spacer is greatlyreduced.The efficiency effectively improves the air-tightness of the insulatingglass,the back is smooth and flat,the front is beautiful and Elegant,and it caneffectively improve the overall strength of the aluminum spacer.
