ㅏ 부엌 싱크대 is an instrument you can use to hold a large amount of water and wash tableware and food. Stainless steel is the most commonly used material.
The manufacturing process includes the welding method and integral molding method.
In this article, we will talk about these techniques in detail.
Integral molding method-stamping
Stanping is a stretching process in which you place a sheet of metal in a stamping press machine. This press will form the metal into a specific shape. The press applies pressure to the sink at certain angles and forms the shape into whatever you want it to be.
그만큼 제조 공정 of a stamp sink is entirely automated. It is capital intensive, which is one of the main reasons the stamp sink is usually cheaper than the handmade sink.
Benefits and Downsides Of Stamping
The first and foremost benefit is that this process saves the sink’s materials and saves labor costs. Additionally, you can make specially shaped sinks with this process and can make your kitchen attractive.
Also, there is no welding, and stable solution treatment improves stainless steel’s performance.
There are certain downsides to this process too. Firstly, there is an initial high investment in buying the stamping press machine.
Secondly, the sink bowl will become thin because of the stamping into a bowl shape. They are more fragile and are more prone to dents and cracks.
Finally, the corners of the sink’s body cannot be too small due to technological limitations. For example, you can not make a zero radius sink by the tamping process.
People also call it 그려진 싱크대 and can only make a single bowl sink with this method.
If you want a double bowl sink, it must add the welding method to finish.
Welding Method
From the perspective of the sink’s market, there are two main types of welding techniques. These are rolling welding and fold welding.
Rolling Welding
This process uses a wheel-type welding machine to finish the welding; it is the most common in making a stainless steel sink. In this process, people can combine the sink bowl with a panel into a whole sink.
In this process, the equipment requirements for stretching are low. You can generally produce hydraulic equipment within 500 tons. However, the requirements for welding and grinding operations usually are high.
The best rolling welding technology is to use the CNC welding machine but not handle by manually.CNC welding and CNC polishing to eliminate false welding so that the polished joints come out very smooth and beautiful.
Rolling welding is also used to combine four sides of a sink in handmade sinks. It uses a wheel-type machine called a rolling press to finish it.
Benefits and Downsides Of Rolling Welding
The advantage is that it has a beautiful appearance, it is not easy to find the weld position, and the sink’s surface is flat and smooth.
Moreover, it’s possible to make a sink with a small sink radius, which the stamping process can not do.
The disadvantage is that some consumers doubt its firmness. Another disadvantage is it needs two steel plates to produce a sink. One is the sink bowl, and another one is for the sink panel.
Fold Welding
The fold welding process combines two stamp sinks with their middle rims, then welds them together into a double bowl sink. The difficulty of this technology is that it is difficult to maintain the central welding position’s flatness.
Benefits And Downsides Of Fold Welding
This method’s benefit is the sink panel and the sink bowl is the same piece steel material. It’s strong and sturdy to use.
The downside is the middle welding position is easy to find, and it’s hard to keep it flat.
A depth of 18mm is the limit for the stamp sink, so if a double-bowl sinks over this depth, it’s using the welding method.
