Like any manufacturing process, injection molding is susceptible to a number of errors that can lead to costly rework and delays. You need to work with an experienced manufacturer to mitigate these risks and ensure a smoother and more successful production process. The best companies in China have high standards for quality assurance in to deliver outstanding results every time. They can also anticipate potential manufacturing challenges and design limitations that might arise during production and proactively address them to minimize errors and ensure that the final product meets the required tolerances.
What causes mistakes in injection molding?
Mold design, resin shrinkage, manufacturing speed, wall thickness consistency, and many other factors influence the success of an injection molding project. While many of these factors primarily affect aesthetics, reputable injection molding specialists prioritize quality assurance to minimize such issues. Seasoned manufacturers optimize the gate location, help customers pick the best resin, and ensure well-designed molds for successful China injection molding.
Defect-free molds and parts
A successful injection molding process starts with a high-quality and well-designed mold. Poorly designed ones can result in low tolerance throughout the molding process, regardless of how feasible your design is. Additionally, using a sub-par mold can result in higher costs and wasted time with low-quality outcomes.
Seasoned China injection molding specialists know all these, so they use only high-quality and durable materials like steel and aluminum for custom molds. They may recommend steel if you need to produce more parts for low-volume end-use or prototype production. The material is proven durable and reliable for making more parts, giving more value to your project.
High-quality plastics
A carefully designed steel or aluminum mold won’t necessarily deliver high-quality parts. You must pick the right plastic resin with a low shrinkage rate, such as ABS and HDPE. Be sure to talk to the China injection molding specialist about using fillers, pigments, and additives. Some additions may enhance the resin’s stiffness, creep resistance, and other properties but can increase the shrinkage rate.
Consistent wall thickness
Reputable injection molding specialists recommend increasing and adjusting the mold’s wall thickness to avoid flaws and part stress. However, this should be done while ensuring consistent thickness.
Strategically placed gates
Gates are channels within the mold through which molten plastic resin flows before filling the mold cavities. Ideally, gates should be placed in the deepest cross-section of the mold to avoid sink marks and voids and improve the resin flow.
