Wulian County Yihe Industry and Trade Co., Ltd. was founded in 2007. It is located in Industrial Park, Fuqiang Road, Wulian County. It has an excellent geographical location and is only 120 kilometers away from Qingdao Port. It has convenient transportation and can realize the delivery of steel ball cargo to Qingdao Port within one day. The company covers an area of 20,000 sq.m., with a production workshop of 3,000 sq.m. It has an annual output of 1 billion steel balls and a registered capital of 5 million RMB. It is a precision steel ball production company integrating scientific research, production & trade. The company has a high-quality, high-tech professional production team dedicated to researching and developing steel ball manufacturing methods and processing technologies. Over the years.  

we can process chrome (AISI52100/GCr15)and  SUS440C and SUS420C balls from 1mm to 3mm and from grades 10 to 40. The plant is ISO 9001 certified and can process 10 metric tons of balls per year.  

The miniature ball facility features machines for each step of mini ball processing, including cold heading, small and large flashing, heat treat (hardening) and tempering furnaces,and 100% inspection around 360 degrees of the ball surface using sophisticated vision equipment.

Why is stainless steel "stainless"?

The corrosion resistance of stainless steel arises from a "passive", chromium-rich, oxide film that forms naturally on the surface of the steel. Although extremely thin at 1-5 nanometres (i.e. 1-5 x 10-9 metres) thick, this protective film is strongly adherent, and chemically stable (i.e. passive) under conditions which provide sufficient oxygen to the surface.

The key to the durability of the corrosion resistance of stainless steels is that if the film is damaged it will normally self repair (provided there is sufficient oxygen available). In contrast to other steel types which suffer from "general" corrosion where large areas of the surface are affected, stainless steels in the "passive state", are normally resistant to this form of attack.

Stainless steels cannot be considered "indestructible", however. The passive state can be broken down under certain conditions and corrosion can result.

This is why it is important to select carefully the appropriate grade for a particular application.

Balls for Metering and Dispensing

Precision balls are used in containers that meter or dispense products such as: airless spray pumps, lotion pumps, atomizers, or continuous or metered aerosol cans. Yihe produces stainless steel balls that are specified for dispensing applications within the health care, cosmetics/fragrances, and household products industries. Yihe also produces balls for specialty applications such as the dispensing of pet treats, and adhesives.
