Stainless steel vacuum cups achieve heat preservation by vacuumizing the air between double layer stainless steel. This technique which did not exist in 1980s become more and more mature with the maturity of heat vacuumizing and double layer high accuracy welding. Till 1995, the production technique for vacuum cups has been gradually steady, and batch production of cups begins. Although there are a few technical staffs and the vacuum stability is low, the cost is vey high. But compared to the traditional glass vacuum cups, because the double layer stainless steel vacuum cups are easy to carry, and heat preservation time is long, not easy to broke, the need for stainless steel vacuum cups is large from 1995 to 1999, and many manufacturers invested in this industry. From year 2000 to year 2003, this is a high speed growth period for vacuum cups, and till now, the market has transfered into a mature developing stage.

Currently, Zhejiang and Guangdong are the two main production bases for vacuum cups, and some corporates in Anhui and Shanghai develops quickly. Some large corporates begin to dominate in this field, whle some tiny workshops decay. China OEM occupies 70% output around the world market, while 50% comes from Yong Kang, and the rest is from Guangdong.

In Yong Kang, regional intergration production chain has been formed. The craft is mature, and the products have thorough purchase channel, so the cost is low. But affected by malicious exclusion from export price competition, low price and quality phenomenon still exists. Large-scale corporates are occupying monopoly advantages, after recognizing export risks, they expand their own brands gradually in order to compete with international brands. The survival chance of small corporates that relay on low price and quality is little. In the future, there will be polarization, and large-scale corporates dominate in market, and the small ones may be eliminated or become the workshops for large companies or occupies in low end market.

In Guangdong, the whole stainless steel products has formed production line. Product craft is mature, and most stainless steel tablewares and other stainless steel hardwares come from Guangdong Caitang, Chaozhou and other places. Domestic sales occupy the most market.

Nowadays, the main brands in domestic market are Sibao, Haers, Xiongtai, Fuguang, Noah, Steer, Jiajiali, Kangyu, Guize, Boenshi and so on.
