In recent years, as consumers pay more and more attention to environmental protection and health, a healthier, more environmentally friendly, and highly recyclable stainless steel faucet casting will become the future trend. Stainless steel faucet is an emerging product, which has become more and more popular in recent years. Consumers' favor, as the technology matures, it will become more and more popular, and to seize more market share of copper faucets, the faucet material will gradually replace copper by stainless steel.

There are four main materials for faucet castings, namely copper, PVC, cast iron, stainless steel, etc. Most modern high-end faucets on the market use pure copper as the main raw material. According to experts, the lead content in copper and bronze faucet castings is usually 4%-8%. If the faucet is not used for a long time, green patina will appear on the inner wall, and the lead and other substances in the faucet may be released into tap water. Drinking lead contains lead. Excessive water can cause lead poisoning, which not only affects the intellectual growth of the drinker, but also seriously affects the health of the body. The world is now vigorously advocating "energy saving, emission reduction, green environmental protection", and the world-famous World Expo has the theme of "green environmental protection".

China's latest "Drinking Water Hygiene Standard" (GB5749-2006) stipulates that the lead content in drinking water shall not exceed 0.01. It is reported that California will adopt a new law from 2010 to prohibit all copper pipes with lead content higher than 0.25%, which will have a certain impact on the future production and use of copper faucets.

In addition, copper is expensive and the price fluctuates, and it has been on the rise in recent years. The rise of copper materials will lead to loss of customers if the price of faucets rises. OEM enterprises with narrow profit margins will not be able to sustain themselves. This has also prompted many enterprises to enter the field of research and development and production of stainless steel faucet products. As the stainless steel faucet does not contain lead, it is resistant to acid, alkali, corrosion, releases harmful substances, and does not pollute the tap water source. It has undoubtedly become the focus of attention of many faucet manufacturers.

It is understood that the surface of stainless steel faucets above 304 does not need to be electroplated (304 stainless steel is the most widely used chromium-nickel stainless steel, 304 refers to a grade of stainless steel produced in accordance with the American ASTM standard), and its surface only needs polishing (grinding) Light) can show the true color of stainless steel, and can continuously maintain the silver-white luster and never rust. The hardness and toughness of stainless steel are more than 2 times higher than copper products. The surface of copper products must be electroplated. The best treatment method for the copper surface is to electroplate a layer of nickel or chromium, and the electroplating layer will gradually peel off depending on its electroplating quality and thickness. One year for the faster ones, and 3-5 years for the slow ones, gradually lose the surface gloss and pitting, and finally the electroplating layer peels off and the copper rust is exposed.

Founded in 2003, Ningbo Suijin Machinery Technology supply all kinds of lost wax investment castings and machining parts or called precision investment castings, material including carbon steel, alloy steel, and stainless steel. we also can according to the customers' requirement to compound the material, Our factory has a floor space of 33,000 square meters and another 18000 square meters of building area, which contain both casting foundries and CNC machining area. The two advanced lost wax casting and investment casting production lines have a capacity of 5000 tons lost wax castings and 1000 tons investment castings per year.
