The process methods of reinforced PVC baseball shells mainly involve material selection, mold design, injection molding and post-treatment processes, etc.
Material selection: When making the PVC baseball shell, it is necessary to choose PVC material with high strength and high toughness to ensure that the shell can withstand the impact and wear during use. At the same time, it is advisable to consider adding an appropriate amount of plasticizers, stabilizers and other additives to improve the processing performance and durability of PVC materials.
Mold design: The mold is the key to forming the PVC baseball shell. Mold design needs to take into account the precision, appearance and production efficiency of the product. In terms of structural design, it is necessary to ensure the reasonable layout of the mold to avoid defects such as product deformation and shrinkage. In terms of surface treatment, the appearance texture and grade of the product can be enhanced through processes such as polishing and texturing. In addition, the exhaust system of the mold also needs to be carefully designed to avoid problems such as bubbles and charring in the product.
Injection molding: Injection molding is the core process in the processing of PVC baseball shells. During the injection molding process, parameters such as temperature, pressure and time need to be accurately controlled. Excessively high temperatures can cause material decomposition, while excessively low temperatures will affect fluidity. Insufficient pressure will lead to incomplete filling of the product, while excessive pressure will cause problems such as flash and burrs. In terms of time control, a cooling time that is too short will cause product deformation, while a cooling time that is too long will reduce production efficiency. Therefore, according to the characteristics of PVC material and the design requirements of the mold, the injection molding parameters should be reasonably adjusted to ensure product quality.
Post-treatment process: The post-treatment process can further enhance the appearance and performance of PVC baseball shells. For example, the spraying process can be adopted to endow the product with rich colors and textures. The electroplating process is adopted to enhance the wear resistance, electrical conductivity and decorative properties of the product. By using laser engraving technology to engrave patterns, text and other information on the product surface, brand value can be enhanced.
