The transformation of stainless steel balls is also related to the characteristics of the medium, especially the oxidation ability of the medium. In the oxidizing medium such as nitric acid, NO3 is oxidizing, the oxide film on the surface of the stainless steel ball is easy to form, and the transfor... read more
Stainless steel balls are usually produced by forging process. At this stage, the commonly used stainless steel balls are 201, 302, 304, 316, 316L, 420, 440C. definition: steel that contains more than 12% chromium and is resistant to chemical substances. Principle: Stainless steel does not ru... read more
The material used in the biodegradable plastic ball is PLA, which can be decomposed by bacteria in the soil or in a humid environment and will not pollute the environment, but the manufacturing method of the biodegradable plastic ball is completely different from that of the POM plastic ball. The sh... read more
The manufacturing of POM plastic ball mold must calculate the shrinkage rate of POM material, but POM plastic ball mold is different from other POM products. POM plastic ball is a solid sphere. The larger the size, the shrinking rate will be doubled, so POM plastic The manufacturing of the ball mold... read more
The density of solid plastic balls cannot be exactly the same due to material reasons and differences in injection molding processing technology. For customers who are not demanding, such differences will not have much impact, but some demanding customers , The density of the plastic solid balls mus... read more
