Brittleness in injection molded products is a non-negligible issue, often closely related to the presence of internal stresses.

In previous articles, we delved into the impact of injection molding machine selection and plastic mold design on material shortage in injection-molded products. Today, we will focus on the injection molding production process and how it influences material shortage issues.

In the complex process of injection molding, there are numerous factors leading to material shortage in products, among which mold design issues are particularly crucial.

In the precise manufacturing realm of injection molding, material shortage is undoubtedly a stubborn issue that affects product quality and production efficiency.

Burn marks on plastic products during injection molding are primarily caused by defects related to residual gas in the mold cavity. So, how can we improve this situation?

In the precise process of plastic injection molding, there are occasional instances where plastic materials fail to enter the screw from the feeder, a problem particularly prominent when processing nylon materials.

Surface blurriness in injection molded products refers to the unclear areas formed on the product's surface due to poor mold interior surfaces or excessive use of mold release agents.

In the process of injection molding, a subtle and barely noticeable line occasionally appears on the surface of plastic products—water marks, also known as weld lines. These hairline seams originate from the interface where molten plastic flows and merges within the injection mold cavity, hence they are vividly termed as flow marks.

In the injection molding process, plastic deformation failure is an issue that cannot be ignored. This phenomenon refers to the situation where localized plastic deformation occurs in the mold cavity under the action of molding pressure and temperature, rendering the mold unusable or even scrapped.

In the injection molding process, surface wear failure of injection molded parts, as a common form of mold failure, refers to the condition where the mold cannot continue to ensure product quality due to severe wear on the mold cavity surface after a period of use.

In the custom processing of injection molds, the precise positioning of workpieces is a crucial aspect of ensuring product quality and production efficiency.

This article details the seven core components of injection molds and their functions, aiding in enhancing injection molding efficiency and quality.
