PEI (Polyetherimide) is a high-performance thermoplastic engineering plastic with excellent mechanical properties, heat resistance, and chemical stability. However, it presents certain challenges in molding and processing.

In the electrical discharge machining (EDM) of injection molds, copper and graphite electrodes are two commonly used electrode materials. Each has its advantages and disadvantages, and the choice of which one is more suitable depends on a variety of factors.

The qualification of an injection mold needs to be comprehensively judged from three dimensions: technical indicators, production adaptability, and durability. Its standard directly affects product yield and cost control.

Medical injection molding, as a precision manufacturing process, plays a vital role in the production of medical devices. Due to the stringent requirements of medical devices in terms of materials, precision, and biocompatibility, medical injection molding differs significantly from general injection molding.

Surface hazing during injection molding primarily results from issues related to mold design, process parameters, or material quality. These factors prevent the product surface from achieving a smooth and transparent appearance.

In injection mold manufacturing, the surface finish of molds directly affects the appearance quality, and service life of molded products.

Injection molding machines can be categorized into two types, horizontal and vertical, according to the direction of the clamping mechanism. These two types have significant differences in structure, process adaptability, and application fields.

During injection molding, incomplete gas expulsion can lead to defects such as short shots, burn marks, and gas traps. As a critical component of mold venting design, scientifically optimized venting grooves are essential for ensuring product quality and production efficiency.

Runner sticking in injection molding occurs when the cooled molten plastic gets stuck in the runner and cannot be easily ejected. This issue can impact production efficiency and damage the mold or the product.

In plastic mold processing, inserts refer to detachable or fixed small components embedded within the mold. Inserts play a crucial role in addressing specific processing requirements or enhancing mold performance.
