The production of rubber ring requires great patience

The difference between the rubber rings supply chain and the Hot water bottle supply chain is the air valve supplier and surface treatment service supplier.

The factory that produces inflatable cushion is a factory that specializes in the production of instrument valves. The products are small in size and require high processing accuracy. The material of the valve is copper, and the white coating on the surface is special electroplated chrome.

The air valve needs to be painted with a layer of Chemlock 6150 before use. Due to the characteristics of Chemlock, the air valve must be completely dried after brushing 6150 before it can be used, otherwise it will fall off after being bonded to the rubber knot. In summer, the valve after brushing 6150 needs to be exposed to the sun for 3 days, and in winter for at least one week before use
