In the process of injection molding, if we want the molded parts to exhibit vibrant colors, the use of color masterbatch becomes indispensable. By mixing the required color masterbatch particles with plastic raw material particles and adding them into the injection molding machine for melting and molding, we can obtain colorful plastic products.

In the production process of ABS plastic, it is not difficult to find that different grades of ABS products exhibit significant color differences. Even within the same grade, different batches of products may also have noticeable color variations.

In the field of injection molding, main runner sticking is a problem that cannot be ignored. It refers to the phenomenon where the main runner of the injection molded part fails to separate from the plastic mold during the ejection process.

In the field of plastic injection molding, product cracking is an issue that cannot be ignored, encompassing various forms from minute cracks to complete fractures. Delving deeper, these cracking phenomena can be attributed to two major causes: mechanical cracking and chemical stress cracking.

In our previous article, we discussed the main causes of stress marks in plastic molding products. Now that we understand the causes, it's imperative to explore ways to minimize internal stress during the production process. With guidance from the engineers at Dongguan Yize Mold, the solutions are outlined below:

In the field of injection molding, when we closely observe finished products made of materials such as ABS, PP, and PC, it is not uncommon to find white or shiny marks on their surfaces.

In the field of injection molding, residual stress, the sum of internal stresses that remain unrelaxed after a product is ejected from the mold, is a key factor affecting product quality.

In the field of plastic injection molding, air traps, as a common defect, essentially refer to the phenomenon where air or gas is not promptly expelled from the mold during the injection process and is instead encapsulated within the mold cavity by molten plastic, thereby affecting the product's quality and appearance.

In the injection molding production process, hot runner molds are widely favored for their efficiency and energy-saving characteristics. However, operators are often plagued by system leakage issues, directly impacting product quality and production efficiency.

In the field of injection molding production, the occasional occurrence of slowdowns undoubtedly poses a significant bottleneck to efficiency enhancement and cost control. It not only directly prolongs production cycles but may also lead to increased overall production costs if not addressed promptly.

In the plastic processing industry, product dimensional stability is a key indicator for assessing the quality of injection molded items. When the dimensions of products produced by plastic injection molds fluctuate frequently, it directly signifies that these products fail to meet established quality standards.

In the field of plastic injection molding, product discoloration is undoubtedly a tricky and urgent problem to solve. It not only affects the aesthetics of the product but may also compromise its performance and quality.
