In the third quarter of this year, Xiamen Industrial and Commercial Bureau conducted a sample inspection of the auto parts sold in the market. The test results show that all samples meet the requirements of national standards.
With the water-sand blasting process, an abrasive agent is added to the high-pressure water, in order to enable efficient paint and rust removal from metallic surfaces. Dust contamination concerns mean that pure sand blasting is prohibited in many countries, or permissible only under strict conditions. Water-sand blasting is an alternative which enables the use of abrasive agents, such as sand, silica sand or ground blast furnace slag, in order to achieve different shot blasting results.
In comparison with purely abrasive agent shot blasting systems, this system has the advantage that no deformation (peening) arises in the shot blasted material. With the water-sand blasting process the heat is removed by the water so no form-changing heat concentration occurs in the shot blasted material. In addition, in case of paint removal with high pressure, the removed material is carried in the water and washed away.
In case of the water-sand blasting process, our AK600 HIGH PRESSURE GUN is provided with an injector, through which the abrasive additive is added to the water. With increasing operating pressure, the required quantity of abrasive agent reduces. Vice versa in comparison with pure water jets, a significantly lower pressure is required for a comparable result.

It is understood that the industrial and commercial departments have conducted a quality inspection of the quality of the auto parts and consumables sold by 11 automobile sales companies and maintenance companies in the city. The spot check involved a total of 38 batches of goods in 12 brands, basically covering the high-end, middle and low-end automobile brands that are more popular in the city.
The types of products tested by this spot check include brake pads, brake hoses, batteries, brake fluids and engine oil. The test items have friction coefficient and low temperature starting ability, which are mainly related to personal safety and national mandatory indicators.
