The draft angle in injection-molded products refers to the inclined angle between the product

The gate is the passage that connects the runner and the cavity in an injection mold. Its location and form significantly affect the quality of the molded part, production efficiency, and mold life. A reasonable gate layout ensures smooth filling of the cavity with the melt, reduces defects, and improves product quality.

In multi-cavity mold design, runner balance directly impacts filling uniformity across cavities and the consistency of product quality.

The inspection and acceptance of injection mold bases are critical steps before mold assembly and manufacturing, directly impacting mold precision, service life, and production stability. Hidden defects or dimensional deviations in the mold base can lead to issues such as difficult mold clamping, ejection jamming, or even product scrap during mass production.

During the injection molding process, after the molten plastic is injected into the mold cavity under high pressure and solidified, the cooled product must be separated from the mold using an ejection mechanism. The primary goal of ejection mechanism design is to ensure that the product is safely and completely ejected from the mold surface with minimal force and uniform stress distribution once it has fully cooled or achieved sufficient strength.

Weld lines, a common defect in injection molding, occur when multiple streams of molten plastic converge in the mold but fail to merge fully. These lines can compromise a product’s appearance, structural strength, and sealing performance.

In injection molding, nylon is modified primarily to enhance its processing performance and final product properties, ensuring suitability for diverse application requirements.

In the injection mold manufacturing process, the surface finish of the mold directly impacts the appearance quality of molded products and subsequent processing.

The ejection system of an injection mold is a critical component of the mold structure. Its primary function is to eject the molded plastic part from the mold cavity smoothly, ensuring product integrity and production efficiency.

In injection mold design, the mold base serves as the foundational framework that carries all mold components, playing a critical role. A suitable mold base not only enhances the structural strength and stability of the mold but also ensures precision and efficiency during the injection molding process.
