How to choose hardware hand tools

As the market for hardware hand tools has received increasing attention and the scale of exports has continued to expand, imported manual tools have also entered the domestic trade market. How can you choose the right hand tool for many brands?

Here to talk about manual tools to buy three principles:

First, cost-effective multi-party inspection of product quality and production Distribution manufacturers are the first part of the purchase of products, such as its operating history, market share and service network. Brand spray guns are generally of reliable quality, but the brand effect often leads to high prices. Domestically produced products of the same type are usually lower in price but their quality and after-sales service are often worrying. Therefore, focusing on cost-effective, or performance first, brand first.

Second, the degree of durability The durability of the spray gun depends mainly on the material used, a good spray gun material has both adequate compressive properties and lightweight weight, and a high quality outer protective layer and internal parts. Many home-made spray guns or foreign brands of low-priced spray guns start to spray well, but the use of one or more months after the emergence of nozzle or gas cap aperture, or needle wear can not continue to use, is its use of material properties Insufficient; there are also spray gun outer coating after a few contact with thin material off, both affecting the visual and affect the use of feel, which is related to poor surface material or plating process level.

Third, the atomization effect A good spray gun is usually atomized, the paint flow is stable, and the paint utilization is high. The atomization effect of the spray gun is related to its internal channel design and the precision of the aperture on the nozzle and gas cap. On the other hand, it is also related to the working pressure. Experienced masters know that brand guns are generally better at atomization than canned guns. High-pressure guns are generally better at atomization than low-pressure guns. The reason is that brand guns are more advanced in their production processes and equipment, and higher precision is more stringent. The high-pressure gun atomization is good because of its high operating pressure, but the large gas consumption, and the low paint utilization.
