As electronic devices continue to become more compact and functionally complex, protecting internal components has become a critical engineering challenge. Low pressure overmolding (LPM) offers a more controlled and production-friendly alternative. Using low-viscosity materials and low injection pressure, it enables reliable encapsulation of sensitive components while improving manufacturing efficiency and consistency. What is Low-Pressure Overmolding? […]

Medical injection molding is a highly specialized manufacturing process designed to produce high-precision medical components. Medical injection molding demands micron-level tolerances, biocompatible materials, and strict process control to meet regulatory compliance. At Zhongde Company, we specialize in custom medical injection molding solutions. Common Materials for Medical Injection Molding Material selection is a foundational aspect of

Injection speed is one of the most critical parameters in the injection molding process. It determines how quickly molten plastic enters the mold cavity and directly affects part quality, cycle time, and production efficiency. A proper understanding of injection speed is important to optimize the injection molding process and minimize defects. To fully understand how

Injection molding is a versatile manufacturing process, but the quality and efficiency of the final parts depend heavily on controlling the right process parameters. Factors such as injection speed, temperature, pressure, and cooling time can dramatically affect part precision, surface finish, and structural integrity. Understanding these parameters not only helps engineers produce high-quality components but

What Is Overmolding? Overmolding is a manufacturing process in which one material is molded over another to form a single integrated part. If you are not familiar with the overall process, you can first refer to All You Need to Know About Overmolding. In plastic overmolding, a secondary plastic material—often softer or functionally different—is applied
