Founded in 1995, Oulin is the hegemon of China's sink market with the highest market share compared to brands such as Franke and Aiken, although it started late. It is responsible for the drafting of the "QBT4013-2010 Household Stainless Steel Sink" industry standard, and the translation of the name of "sink" was first proposed by Ou Lin.
 
The Oulin product line is very comprehensive, with both stainless steel and granite materials, and the functional classification includes not only ordinary sinks, but also integrated water purifier sinks and dishwasher integrated sinks. The stainless steel sink is the most classic OLJD series, with a plate thickness of 1.0mm, a groove depth of 220mm, a single tank length of 600mm, 680mm, and 780mm to choose from, and a double tank of 780mm, with a water filter basket and 59 copper faucets. The OLWG series is an improved version of the OLJD series, which adds a "bay moon" design in the upper middle of the OLJD tank, that is, a semi-curved shelf that can be placed on top of the steel wool ball and rag.
 
In the granite series, the Black Knight WGS series can best represent the design level of Oulin, equipped with square grooves and round grooves, square grooves WGS10401 with R10 rounded corners, mature manufacturing technology, frosted surface treatment, anti-fouling and damage resistance, reserved faucet openings above the groove, priced from 2300 to 2700 yuan.
 
The integrated tank of the water purifier is a series launched by Oulin in recent years, facing the high-end market, the main material is still stainless steel, the thickness of the groove is 1.2mm, and then it is manually polished after stamping, which is a typical "manual groove". The faucet is divided into an ordinary faucet and a water purification faucet, and the water purification faucet is connected to a water purifier for direct drinking water. The touch screen of the water purifier is set above the small slot, which supports flushing, resetting and child lock functions, and also supports table-controlled water storage. However, the sheer size of the system is a test of durability, and it is not recommended for consumers who want long-term practicality to buy such complex sinks.
 
Oulin is positioned in the mass market, the price of the sink is relatively close to the people, the price of the stainless steel tank set is around 1000 yuan, the standard is equipped with a common high-throwing faucet, and the price of the flat throwing and pull-out faucet is 100-300 yuan higher on the original basis; The granite sink is priced at about 2,500 yuan, while the water purification sink is priced at as high as 4,000-8,000 yuan. In terms of after-sales, the single-function sink supports a 3-year warranty, the faucet supports a 10-year warranty, and the integrated sink of the water purifier is a new product on the market in recent years, and the technology and process are not yet perfect, and the water purification sink of Oulin only supports a one-year warranty.
