Hello there! This is Alex from Wuxi Honfon Sports & Fitness. In my previous article a few days ago, I introduced the importance of baseball training balls and the general material and composition of sand-filled baseballs. Today, based on our many years of production experience, let’s dive into the detailed characteristics of these sand baseballs.
Let’s start with the materials. The main components of wholesale baseball training balls are PVC and iron sand. In terms of physical properties, PVC offers better elasticity, firmness, and durability. Chemically, PVC is resistant to corrosion, high temperatures, and oxidation. From a manufacturing perspective, PVC is highly customizable—its color, odor, softness, elasticity, shape, density, and more can be tailored to meet specific requirements. Compared to old-style baseball training balls, these affordable weighted baseballs can be made more visually appealing and personalized. If you’re a wholesaler, you know that attractive products can significantly boost consumer interest.
Of course, aesthetics alone aren’t enough. The end user’s experience and satisfaction are the driving forces behind sustainable product sales. Now, let’s discuss the iron sand, which determines the weight of these affordable heavy baseballs. Are the sands used in slam balls and these heavy baseballs the same? The answer is no. Typically, slam balls use natural sand because its density is lower than that of iron sand. To ensure the filler occupies more than 3/5 of the ball’s volume, a higher percentage of natural sand is used in slam balls. For wholesale practice baseballs, however, the smaller size usually requires iron sand as the filler. Compared to the iron sand in slam balls, the grains in these new training balls are much finer. This ensures smooth sand flow, enhancing the feel of hitting and throwing, as well as the ball’s shape recovery.
That’s all for today’s article. In the next one, I’ll introduce various customization methods for these affordable sand-filled baseballs—how to make your training ball better suited to your specific needs.
