In the production process of low-cost PVC baseball, efforts can be made from the raw materials, molding, post-treatment and packaging stages to reduce costs while ensuring product quality.
Raw material selection and processing
Raw material selection: Under the premise of meeting the basic performance requirements, PVC materials with high cost performance should be selected. For instance, choosing domestic PVC resin of qualified quality can meet the performance requirements of baseball production and has a relatively low cost. At the same time, it is necessary to rationally combine environmentally friendly plasticizers and stabilizers to ensure the environmental performance of the product while controlling costs.
Recycling and reuse of waste materials: The PVC waste materials generated during the production process are recycled. After undergoing processes such as crushing, cleaning, and drying, they are reused as raw materials. This can not only reduce the cost of raw materials, but also decrease the generation of waste, which meets the requirements of environmental protection.
Optimization of forming process
Injection molding process parameter adjustment: Through multiple mold trials, the optimal combination of parameters such as injection pressure, injection speed, holding time and cooling temperature is found. On the premise of ensuring the dimensional accuracy and roundness of the baseball, appropriately reduce the injection pressure and speed to decrease energy consumption and equipment wear, thereby reducing the production cost. For instance, while ensuring the filling effect, appropriately reducing the injection pressure can decrease the energy consumption of the equipment and the wear of the mold.
Mold design optimization: Adopt a reasonable mold structure to reduce the complexity and manufacturing cost of the mold. For instance, simplify the gate and runner design of the mold to reduce the processing difficulty and cost of the mold. Meanwhile, optimize the cooling system of the mold, improve the cooling efficiency, shorten the production cycle and enhance the production efficiency.
The post-treatment process is simplified
Reduce unnecessary processes: Under the premise of ensuring the performance and appearance quality of the baseball, minimize post-processing procedures as much as possible. For instance, if the surface quality of the baseball already meets the requirements, processes such as grinding and polishing can be omitted, thereby reducing production costs.
Adopt efficient post-treatment methods: For the necessary post-treatment processes, adopt efficient treatment methods. For example, heat treatment correction is adopted to replace part of the mechanical processing correction, which improves the correction efficiency and reduces the production cost.
Improvement of packaging materials and methods
Choose economical and practical packaging materials: Use economical and practical packaging materials such as paper packaging boxes or degradable plastic packaging bags to replace expensive packaging materials. This can not only reduce packaging costs but also minimize the impact on the environment.
Optimize packaging methods: Adopt reasonable packaging methods and reduce the usage of packaging materials. For instance, adopting a compact packaging design can enhance the utilization rate of packaging space and reduce packaging costs.
