The sink is one of the indispensable tools for modern kitchens to wash dishes or dishes. Stainless steel sinks are divided into two types: stretch sinks and manual sinks. Below, Stainless Steel Handmade Sink Manufacturers detail the two different sink features.
Manual sinks are mid- to high-end products in the market. Each process is manual processing, and the entire processing process is to ensure that the originality of the stainless steel plate is not damaged. Therefore, perforated cracks and corrosion will not occur in the manual sink.
Manual sinks generally have a thickness of 1.2-1.5mm. Stainless steel plates of this thickness cannot be stretched on the mold, and they will break once stamped
Stretching the sink, the manufacturing process includes shearing, stamping, trimming, spraying, and packaging. Because the production process is relatively simple, the manpower used is not much. The most important manufacturing process is stamping. Stamping requires a fixed mold, one mold corresponds to one product.
Advantages: less consumption, low output, mass production of products, low cost. The disadvantage is that the product is relatively thin, and it is easy to perforate and crack during use. But now basically better sinks are rarely perforated. The thickness of the bottom basin is generally 0.6 ~ 0.8mm.
3.How to distinguish these two sinks
a.The bowl liner of the stretching sink is punched out by the machine, not welded. So there is no welding path on the back of the stretch sink, while the manual sink is welded.
b.Because of the general water tank, the anti-condensation coating is sprayed on the back to cover it up. So we distinguish from the front. The R positions of the stretching water tank are relatively large and look smooth. The R position of the manual sink is relatively small, and it is generally designed with a right angle or a small rounded corner of R10.
c.Then distinguish from colors. Manual sinks usually have a process called "demarcation line polishing", that is, polishing where the structures intersect. There is no stretching sink.
