Injection molding is a field with very high technical content. In addition to years of experience, there must be a heart that is good at discovering, and it is very skilled in the whole process of injection molding. Properly learning all aspects of injection molding requires a lot of trial and error, constant trial and error and summary. But given our many years of innovative experience in the field of injection molding, we can help all those who want to work on injection molding to take fewer detours. And don't have time to think about it.
The design of injection molded parts requires a combination of manufacturability, practicality and aesthetics. Make compromises between factors such as repeatability, cost, strength, functionality, and aesthetics. A balance will be sought to ensure that all of these factors are not below the minimum requirements. From the point of view of injection molding, design parameters such as part wall thickness uniformity and part wall thickness itself are the most critical factors. Uniform part thickness will ensure that defects such as warpage, distortion or cracks caused by uneven wall thickness caused by the cooling of the part at different cooling rates are minimized. Part thickness considerations are primarily determined by cost, part strength, and production speed. Thicker parts cost more because they consume more plastic, while thinner parts cool faster and can be discharged earlier, saving critical time in the production process. However, thicker parts are generally stronger despite the extra cost.
