Ordinary hollow aluminum spacer:

Ordinary hollow aluminum spacers are produced by cold drawing and solidification method, and are subjected to five-way drawing by cold-rolling and drawing equipment, and become a finished product after remodeling, punching, and other flow processes. There some chemical materials are used in the production process of the five cold drawing. Therefore, the discharge of chemical wastewater generated will pollute the environment and generally do not meet the national production execution standards.

Ordinary hollow aluminum spacers surface color is usually sub-color with no gloss and poor flatness. If the surface treatment is not good, there will be bumps and irregular pores.

In addition, ordinary hollow aluminum spacers are not resistant to oxidation and corrosion, and have a certain influence on the activity of the desiccant, which shortening the service life of the insulating glass.

High-frequency welding hollow aluminum spacers:

一. Production technology: bending and non-bending high-frequency welding hollow aluminum spacers adopts water-free circulating German technology, high-frequency welding after aluminum strip calendaring. And it is the national referral production equipment with the feature of production environmental protection.

二.Material: High-frequency welding hollow aluminum spacers adopt high-quality anti-corrosion high-purity aluminum with the wall thickness of 0.35mm, and the quality is guaranteed.

三. Advantages:

  •   With the advantages of no oxidation, no corrosion; even in rainy areas or humid places, it is not easy to oxidize and corrode, naturally the service life of insulating glass will be long.

  • The surface brightness is high, tidy and smooth, with no bumps.

  • Eliminate welding defects, double row of holes, uniform hole penetration, good straightness.

  • It has no effect on the desiccant, ensures the activity of the molecular sieve, and has excellent adhesion to various types of glue.

  • High strength, good toughness, no deformation, stable size.


 Bending high frequency welding hollow aluminum spacers

As we all know that high frequency welding hollow aluminum spacers include bending high-frequency welding hollow aluminum spacers and normal aluminum spacer. In addition to all the five advantages of high-frequency welded hollow aluminum spacers, bending aluminum spacer has a great advantage for insulating glass.


The common installation method of the aluminum spacer is to use four connecting angles to make the insulating glass. When making the four corner edges of the insulating glass, if the operation is not good, the sealing effect is poor, and the first performance of the insulating glass is that the leakage point is increased. There will be air leakage and water permeability, which will easily cause the failure of the insulating glass and shorten the service life of the insulating glass. However, the bending high-frequency hollow aluminum strip is continuously bent during the installation which conveniently eliminates the root source of the four corner leaks, the aluminum frame molding standard is unchanged, the glass splicing is more convenient, and the produced hollow glass reliability High, will not affect the quality of insulating glass products due to air leakage at the four corners

At present, high-frequency welding aluminum spacers are selling well on the market, which shows that more and more high-end insulating glass customers are slowly leaning toward high-frequency welding of aluminum strips. I believe that high-frequency welded aluminum spacers will replace ordinary hollow aluminum spacers in the near future.
