How is a stainless steel tea drain made?

In the past two years, bubble tea cups have become popular, which is probably a reincarnation of tea culture. There are glass, ceramic, and stainless steel tea cups. The tea drain of stainless steel tea cups is also made of stainless steel. How are the small holes in the tea drain made? What is the production process of tea drain? What material is used for the tea drain? Why is the diameter of the hole in the tea drain so small? Why do it so intensively?

Stainless steel tea drains are usually made of SUS304 stainless steel because 304 stainless steel is food grade. Why must it be food grade? Because the tea drain needs to be in contact with water for a long time. Yongkang Minjue undertakes OEM orders for stainless steel water cups and plastic water cups around the world.

If non-food grade stainless steel is used, it will be harmful to the body after people drink the soaked water for a long time.

Why is the diameter of the hole in the stainless steel tea drain so small? It is small because it prevents tea residue and tea dust from leaking into the tea, which will affect the quality and taste of the tea. Why are these holes so dense? This design can allow the tea leaves in the tea drain to be fully and quickly soaked to satisfy people’s drinking.

How are the holes on the tea drain made? At present, various factories usually use etching and laser drilling processes to produce stainless steel tea drain holes. Only these two processes can produce holes with small diameters, and the production cost is relatively low and the production efficiency is high. In the production process of tea drains, most factories first cut the plate, then punch holes, then cut it into small plates according to the product size and roll the tube, then weld the bottom, etc., and finally perform electrolysis treatment.
