The secret of injection molding chamfering vs beveling

Injection molding process, the design and processing of chamfering and beveling are particularly important, they are not only related to the appearance of the product design, but also affect the product's functionality and safety of use. The following is an in-depth discussion of the difference and application of chamfering and beveling in the injection molding process.

Chamfering refers to the rounded corners of plastic products to form a certain arc of the transition, while the beveled corners are in the edge of the plastic parts to make a beveled transition. Both seem simple, but in fact in the design and processing have very different technical requirements and effects.

From the design point of view, the design of chamfered corners often takes into account the aesthetics and feel of the product. Rounded corners can give people a gentle, comfortable feeling, but also avoid the sharp edges may cause unsafe factors. In addition, rounded corners can also reduce the internal stress concentration problem of the material to a certain extent, and improve the overall strength of the product. In the injection molding process, the design of the chamfer needs to pay special attention to the size of the radius, which will have a direct impact on the production of the mold and the product's demolding performance. Generally speaking, a small chamfer radius helps save material, but it will increase the difficulty of demolding, and may even lead to the production of product defects.

In contrast, the design of beveled corners focuses more on function and ease of use. For example, in some fasteners or embedded structures, the appropriate bevel design can facilitate the assembly and disassembly of parts, but also to ensure the stability of the structure. In the injection molding process, the size and angle of the bevel selection has a greater impact on the degree of mold wear and the quality of product molding. Too large a bevel angle may cause material waste, while too small a bevel angle may cause product shrinkage or deformation problems.

In actual production applications, the design of chamfering and beveling is not isolated, they often need to be considered in a comprehensive manner according to the specific needs of the product. For example, in a complex plastic component, some parts may need to use rounded corners to achieve a smooth appearance and a comfortable grip, while other parts need to ensure that the structure of the precise beveling design to ensure that the structure with the realization of the function. Therefore, designers must have a clear understanding and reasonable planning of the application of these two types of corners when designing products.
