Plastic shells have various shapes, and there are different difficulties and differences in their production process.
For simple regular shapes of plastic shells, such as square or round, the production process is relatively mature and easy to control. In the injection molding process, the mold design is relatively simple, and the melt can fill the cavity more evenly. However, the difficulty may lie in the control of dimensional accuracy. Due to the simple shape, small dimensional deviations may be more obvious, affecting the assembly and appearance quality of the product. For example, the side length of the square shell must be precisely consistent, otherwise there will be problems such as uneven gaps during assembly.
For complex shapes of plastic shells, such as designs with curved surfaces, hollows or irregular protrusions, the difficulty of the production process increases significantly. In terms of mold design, more factors need to be considered. For example, for curved structures, it is necessary to ensure that the mold can accurately shape the required curved surface shape and will not cause damage to the product during demolding. The design of the hollow part needs to consider the strength of the mold and the rationality of the demolding mechanism to prevent the product from breaking during demolding. In addition, during the injection molding process, the flow path of the melt of a complex-shaped plastic shell is more complicated, and defects such as incomplete filling or bubbles may occur. This requires precise adjustment of injection molding process parameters, such as injection pressure, speed, and temperature, to ensure product quality.
In terms of differences, the production efficiency of simple-shaped plastic shells is usually high, the mold cost is relatively low, and it is suitable for large-scale production. However, due to the complexity of mold design and manufacturing, the cost of complex-shaped plastic shells is high and the production cycle is long. However, from the perspective of product innovation and aesthetics, complex-shaped plastic shells can give products unique appearance and functional advantages. In short, different shapes of plastic shells have their own difficulties and differences in production processes, and reasonable design and process optimization are required according to specific product requirements to ensure the production of high-quality plastic shell products.
