Standard for checking the quality of the sink

The quality inspection of the water tank requires multiple inspections from materials, processes, and configurations.

The inspection of the quality of the sink is carried out from the purchase of the raw materials, and the inspection is carried out to ensure the material of the sink. In the production process, each inspection process has a special inspection personnel to conduct a full inspection of the product, which can effectively ensure the quality of the product.

There are also many places to pay attention to in the inspection of finished sinks!

Here's how to get the quality of the inspection sink:

1. Hole position - rear position, middle position, side position. The rear position is best, so that there is more space in the lower part of the cabinet. The side position is second.

2, material - hardness, gloss. Generally 301, 304, 430 stainless steel. 304 stainless steel is the best. Our company's water tanks are made of high-strength, corrosion-resistant high-quality imported SUS304DDQ material, containing about 8% nickel. It has good corrosion resistance and oxidation resistance, light weight, abrasion resistance, high temperature resistance, aging resistance and no rust


3. Thickness - overall stiffness. The thickness of the drawing sink generally ranges from 0.4mm to 0.9mm depending on the customer's specific requirements. The thickness of the handmade sink is generally 1.0mm, 1.2mm, 1.5mm, 3.0mm and other different thicknesses.

4, the edge - thin side, narrow side, straight side. Generally, the side height is less than 4mm, the side width is less than 20mm, and the best is to make the table top flat, prevent side leakage, and the basin has an effective volume.

5, the verticality of the basin wall - vertical pelvic floor, arc angle. The vertical angle is the best, so that the effective area of ​​the pelvic floor is large and easy to operate.

6, depth - shallow, deep generally > 180mm best, deep basin, large washing, splash-proof.


7, flatness - the most intuitive standard of quality and grade. Generally should be between +0. 1mm, reflecting the processing accuracy and aesthetics.

8, the lower pipe fittings - accessories precision rigid PP / PVC material is the best, with the sink life, anti-clogging, no water leakage.

9, the water device - a steel joint finished anti-extrusion spiral extrusion. The steel ball is positioned optimally, it is convenient to store water quickly, and the water is automatically filtered.
