The YH-series sand blast machine is the first to be designed in the world by using the principle of matrix pressure equalizing, not only meeting the requirements for high quality and cost reduction of aluminum section material products, but also filling in the blank of this product.

The lowest one-time equipment investment, the lower cost of operation and the fastest recovery of the equipment cost have ensured the improvement of the economic benefits of an aluminum material producer fundamentally. According to different models and different types of material, it can, within 30 seconds, process 1-3 bars of 6-meter-long section material at one time on four sides, while among such foreign products with the same price, the great majority process material on one side. The YH model uses the internationally advanced principle of matrix pressure equalizing gas blowout, technically, ensuring the effect of the evenness of mechanical sand blast, and effectively overcoming the phenomenon of deformation after the processing by a similar sand blast machine. This apparatus requires that the thickness of aluminum section material is more than 0.8 millimeters, and after blasting treatment, the section material will not be out of shape. Compared with alkaline etching, the requirement of this apparatus for the quality of aluminum section material is comparatively loose. The quality of the apparatus is guaranteed and its production performance steady, and it has succeeded in being put into operation in more than 100 aluminum section material factories at home and is exported to a lot of countries in Southeast Asia.

According to the contrast of the above data, for the blasting treatment of one ton of product, the cost is RMB236, and the cost for the chemical etching of one ton is RMB842, saving RMB606/ ton by contrast.
