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

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.

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.

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.

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.

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.

Throughout the manufacturing and operational lifecycle of injection molds, the data plate (Data Plate) serves as the mold’s "ID card," carrying critical technical parameters, management information, and safety identifiers.

Reverse engineering of injection-molded products involves measuring, analyzing, and reconstructing a 3D model of an existing injection-molded part and then designing the corresponding injection mold.

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.
