What is the reason for the poor effect of injection molded products

When using injection molding molds to produce some parts or objects, there may be situations where the product appearance and quality are not up to standard, which is a common problem in injection molding production processes. What factors may lead to poor injection molded products? Let's take a look at the triggering factors together below.

How to inspect the molds for injection molding

To ensure that the injection molding molds meet the standards, it is necessary to consider the application regulations and design schemes, as well as ensure their service life. Normal construction and production require quality assurance of mold specifications from the aspects of product quality, mold structure, and injection molding process regulations. On the other hand, the transformation of household appliances has also driven the deep development of the plastic mold industry for household appliances. At present, large and fine injection molding molds have gained more and more attention from enterprises. Unintentionally, it has put forward higher requirements and tests for the domestic plastic mold industry. So how to inspect the injection molding mold?

How to deal with silver wire in alloy injection molding?

Silver wire refers to a small silver line that appears on the surface of injection molded products, usually due to the insufficient melting of the alloy material during the injection molding process to form a dense melt flow, resulting in tensile marks between the melting points, leading to the appearance of silver wire in the final product.

Reasons and solutions for silver stripe defects in injection molded products

Silver pattern, also known as material flower, is a common phenomenon in injection molded products. It behaves like layered plastic shavings that need to be peeled off. Mainly due to the evaporation of air or moisture in the plastic, or the decomposition of other types of plastic mixed in and burnt, splashing like scars are formed on the surface of the product, usually radiating outward from the gate in a fan-shaped manner. Plastic generally absorbs moisture from the air during storage. If it is not sufficiently dried before injection molding, the residual moisture will be converted into water vapor during the injection process, resulting in splashing marks on the surface of the product. During the plasticization stage of the injection molding material, a certain amount of air will be trapped in the melt. If this air cannot be smoothly discharged during injection, silver lines will also appear on the surface of the product. In addition, cracked or burnt plastics can produce silver lines on the surface of the product. Silver lines are mainly caused by the following reasons:

How to solve the problem of insufficient injection during the production process of injection molds?

The phenomenon of under injection in the production process of injection mold, that is, partial incompleteness at the end of the material flow or partial filling in the multi cavities of the first mock examination, especially in the thin-walled area or the end area of the flow path, will affect the product quality and production efficiency. Here are some solutions to address the phenomenon of under registration:

How to solve the problem of the mold reset plate not resetting after the injection mold is opened?

Confirm whether the reset cylinder leaks oil, as oil leakage can cause uneven force during mold reset. If the oil seal is found to be aged or worn, it should be replaced with a new one in a timely manner.
