What are the common manual sink materials?

Today I want to introduce you to the knowledge of hand-made sinks. So, do you know what a manual sink is? Manual sinks , as the name suggests, are all hand-manufactured sinks, and do not use CNC full-mechanized production processes. This is not the underdeveloped production equipment, but the characteristics of manual sinks , which can only be produced by hand. The production process includes welding, grinding, belt grinding, padding, spraying, and sand pushing. Now is the era of high-tech CNC. Why are there hand-manufactured sinks? Let me show you the answer below.

Manual sink material

There are usually four different types of materials, namely: 1.201 stainless steel (containing 1.1-1.5% nickel), 2.202 stainless steel (containing 5% nickel), 3.304 stainless steel (containing 8% nickel), and 4.316 stainless steel (containing 12% nickel). 316 stainless steel is particularly expensive for use in medical precision equipment.

Manual sink production process


Computer and hand soldering. First manual welding, followed by computer welding, computer welding quality inspection required to ensure the quality of each sink.


Dealing with weld marks is a process of beautifying, smoothing the surface and drawing lines.


The weld mark disappears through the belt, and the beautiful straight drawing pattern is reproduced.



The bottom and side walls of the sink are covered with green sponge pads.


Thinner, flatter, with environmentally friendly water-based spray material.

Push sand

Re-optimize the surface of the sink to ensure a smooth surface and a clear straight draw pattern.

How to judge the merits of manual sink

1, welding, no welding, prevention of embroidered, off welding.

2, the surface texture is delicate, exquisite overflow hole design.

3, environmental health, easy to clean, flatness is good.

4, with PVC material, with the same life tank, anti-blocking, no leakage drip.

5, the thickness of 1.0 ~ 1.5mm, 1.2mm of relatively good quality.


Manual sink production reasons

Manual sinks can meet consumer demand, thickness 1.2-1.5mm, mechanical processing can not be completed, can only use all hand polished.

Editor's summary: The above is the knowledge of the common manual sink material which is how to choose, I hope to help friends who have this need!
