1.Raw material
Our factory refused to adopt SS201 material to produce the sink.Stick to own principles, in order to gain market recognition, to build its own brand "DHK" lay the foundation.

2.Laser equipment
Adopt the  Germany  laser equipment to facilitate innovation and research & development, so as to effectively control the quality.
        
3.Bending
To make the good quality sink, we do not stretch the steel or pass it through fire as these processes would damage the entire thickness of finished sink as well as its structure. We do our best to restore the original quality of SUS304 stainless steel. A real fabrication process starts with bending which forms the right angle bend of the sink. The process followed is computerized welding.
        
4.Computerized Welding

Before welding takes place, manually join the seams together. For a double-bowl sink, we make sure each corner of the bowl is carefully welded before welding the two bowls together. Just because the welding process is computer controlled does not mean we do not inspect the welding quality. In fact, our men check the quality of each welded sink.


Here is a little tip for you to judge whether the welding work is well done. Check the sink corner for a white line. If the sink does have such a line, it should be of high welding quality.

Fabrication means the sink does not need stretch forming process but the labor intensive welding work instead. The seams along the corners need to be manually welded. The snap fits and bowl corners require spot welding. Each time of welding requires experienced welding technicians and their attentive operations to ensure the weld quality.

        
5.Brushed

The purpose of polishing is to remove welding stains and restore the beauty of sink corners so that buyers can get a flat sink surface and clean lines.All of them used by machine



        
6.Fine Polishing by Abrasive Strip

Fine polishing aims to make the welding seams disappear by means of the abrasive strip.



        
7.Sticking Pad onto the Sink Bottom

On the underside of the sinks you can find a black pad stuck on them. We also apply pads to the four sides of the sink to stop it sounding tinny during use.



        
8.Spray Painting

Spray painting allows the sink to have a much thinner coating than that of an ordinary stretch formed sink. Thinner coating means flatter sink surface. The coating material we use is odorless, water-soluble paint free of methanal.And directly through 200 degrees high temperature furnace baking paint more solid.


        
9.Fine Grinding

The purpose of fine grinding to refine the surface of sink so that no or little further surface treatment is needed.
