Stainless Steel Ball(304, 316, 420, 440) is a type of ball made from stainless steel
PP Plastic Balls
Polypropylene (PP) plastic balls are spherical plastic products made from polypropylene. They are lightweight, chemically resistant, have low water absorption (<0.01%), and are resistant to both low temperatures (-30°C) and high temperatures (approximately 100°C). They are non-toxic, semi-crystalline thermoplastics commonly used in industrial, environmental, and medical applications.
Polypropylene plastic balls have a density of only 0.88 g/cm³, making them lighter than water. Their lightweight and low density make them suitable for floating applications and reduce equipment weight.
They offer excellent chemical resistance against acids, alkalis, solvents, and corrosion.
The material's low water absorption, combined with its excellent electrical insulation properties and low dielectric constant, makes it ideal for use in electrical equipment and precision bearings.
Polypropylene is environmentally friendly, non-toxic, recyclable, meets food-grade and medical standards, and offers a long lifespan. It also supports high-precision processing and customizable colors and surface treatments to enhance product aesthetics and functionality.
Changzhou Risheng Steel Ball Co., Ltd. is located on the eastern shore of Taihu Lake, adjacent to Shanghai, with convenient transportation. Since its establishment in June 1995, the company has been dedicated to developing and manufacturing steel balls, integrating research and development with trade.
For many years, Risheng building on the foundation of the Wujin Metal Ball Research Institute, has been committed to researching steel ball manufacturing technology. We primarily produce shaft steel balls (AISI 52100), stainless steel balls (AISI 201/304/316/420/440/430), and carbon steel balls (AISI 1015/1045/1085) with diameters ranging from 0.8mm to 25.4mm, with precision grades up to G10, G40, and G100. We also offer custom specifications for alloy steel balls, military steel balls, copper balls, UFO balls, ceramic balls, and other metal balls.
Packaging & Deliver of Polypropylene(PP) Plastic Ball
High-strength inner packaging: Shockproof foam bags or custom plastic boxes are used to secure each PP plastic balls in place, protecting it from impacts and scratches.
Moisture-proof protection: A moisture-proofing agent is added to effectively prevent the impact of moisture on the product during transportation.
Sturdy outer packaging: Thickened corrugated cardboard boxes or wooden pallets (for large orders) are used to ensure safe long-distance transportation.
Clear labeling: Product specifications, quantity, and drop warnings are clearly marked on the outer packaging box for easy verification and safe handling.
