Six Ways To Build Good Stainless Steel Kitchen Sinks 



How to make a good Stainless Steel Sink for kitchen?  Stainless Steel Sink is made by Deep Draw Stamping Mold, many factors should be considered in Stainless Steel Sink mold design, during mold testing, it's requested several improvements to get good sink parts. There are six important points to be paid attention as follows.


A) Steel Material


High quality material is half successful with regard to make good stainless steel sinks, so for the deep draw, we must pay attention to steel material. Cold rolled plate is used with many different types such as 08Al, 08, 08F, 10, 15, 20 # steel, imported steel such as SPCC-SD deep draw steel from Japan, better than 08 Al. 




Stainless Steel Kitchen Sinks



Using stainless steel as the raw material for the production of stainless steel dishwasher sink parts, the main body is processed through an integrated stretching or welding process, and the product of forming after surface treatment is used as an indispensable part of the installation of the cabinet. The final product is used in modern kitchens as an indispensable tool for washing dishes or dishes.



B) Determination of Blank size


Blank size is also very important to make Steel Steel Sink with table die. The blank diameter of a simple-shaped spiral drawing piece is similar to that of the original one, although the thickness of the material varies from one to the other in the unthinned drawing. Need to go through a number of processes, the first process is generally the blanking process. In order to determine the overall size of blanking die of stainless steel sinks, a general understanding of the shape and size of blanks should be made. After the die design is completed, do not process the dimension of the blanking die, first use wire cutting to process the blank (milling machine can be used to milled the blanks when the blank is larger, then the clamp is repaired). After repeated experiments in the subsequent drawing process, the blank size is finally determined. Then process the blanking die of the concave punch.

C) Drawing ratio 'm'


Stainless Steel Sink Mold and it's Draw Ratio is one of the main process parameters in drawing die technology, which is usually used to determine the order and times of drawing. There are many factors affecting drawing ratio, it's including 


Material properties

Relative thickness of the material

Drawing method 

Drawing times 

Stretching speed 

Radius of concave punch fillet

Lubrication


D) Apply lubricating oil to the die or film bag on the sheet 


E) Heat treatment 


In the process of drawing for stainless steel sinks, due to the cold plastic deformation, cold work hardening occurs, the plasticity decreases, the deformation resistance and hardness increase, and the mold design is unreasonable, so the final annealing is needed to soften the metal and restore the plasticity.

We need to pay attention to several matters. Annealing in the general process is not necessary, after all, to increase the cost, to increase the process and increase annealing selection, careful use. Annealing generally uses low temperature annealing, that is, recrystallization annealing. There are two points to note when annealing: decarbonization and oxidation. Oxidation after oxidation, the harm has two points: make the effective thickness of the product thinner, increase mold wear. Ordinary annealing is generally used. In order to reduce the production of oxide scales, the furnace is filled as much as possible when annealed. There are other ways to reduce the production of oxide scales.

F) Supplementary content 


The stainless steel sink product drawing dimensions should be marked in one side, which can be checked clearly whether is inner size or outer size. Ceeto company has a big group staff who are having more than 20 years experience to make deep drawing die to produce stainless steel dishwasher sink products, mould is compund die which includes blanking die, shearing die, restriking die, flanging die, material is stainless steel 304, surface treatment can be: silver pearl surface, polished wire drawing surface, mercerizing surface and polishing mirror surface. 


Workshop to make stainless steel sink


Good stainless steel sinks all use relatively thick plates. Because dishwasher sink has been treated at the edge, it is difficult to see the thickness at once. The simplest way is to press the surface of the sink slightly hard. If it can be pressed, the material is very thin. Of course, if you can borrow a Vernier caliper and a spiral micrometer, don't bother.


Deep Drawing Technical Processing to Make Stainless Steel Sishwasher Sink


1. Machine: generally using a large tonnage hydraulic press (200t) to draw the sheet metal die

2. Die: the angle can not be too straight, generally more than φ 10 directly, the structure should be reasonable

3. Material: generally require plate thickness range within 0.8-1.0mm, beyond this range, even 500t hydraulic press is powerless 

4. Heat treatment: the whole drawing tank generally needs high temperature annealing treatment, generally 1200 degrees above the temperature, to eliminate the internal stress after drawing 

5. Surface treatment: satin, polishing, polishing (usually smooth) 

6. Process: after the sheet metal is added to the drawing oil of the die, it can be drawn smoothly, annealed after forming, and then treated with surface treatment

Quality Control to Check Stainless Steel Dishwasher Sink Product


1. Welding should be correct, polished surface texture should be uniform, no obvious scratches, hammers and burn marks 

2. The welding position of the flume should be firm, the welds should be uniform, and there should be no defects such as incomplete penetration and cracks. The exposed welds should be polished or decolorized. 

3. The edge of the sink should be smooth and not to have sharp corners and burrs


With the development of the whole economy of our country, the living standard of the people has been generally improved. The cement sink and ceramic sink have become the kitchen utensils in our memory. We hope that you may choose us as your supplier to get good quality kitchen dishwasher sink or commercial dishwasher sink. If you have any questions about dishwasher sink products, please don't hesitate to let us know, we shall be very glad to give you feedback at the first time.
