What are the common faults and solutions in injection molding in Dalian?

Unstable temperature control: leading to unstable product forming quality or defects. The solution is to check the temperature control device of the heating system and promptly repair or replace damaged components.

Mold rusting: causing defects on the surface of the product, affecting the appearance quality. The solution is to maintain the mold before production, regularly clean and apply rust inhibitors.

Injection speed too fast or too slow: too fast can cause internal bubbles in the product, while too slow can cause uneven surface of the product. The solution is to adjust the parameters of injection speed to meet the requirements of the product.

Unstable injection pressure: leading to inconsistent product dimensions or thin wall phenomenon. The solution is to adjust the parameters of injection pressure to ensure stability.

Excessive or insufficient material temperature can cause a decrease in the physical properties or deformation of the product. The solution is to adjust the temperature control of the material to meet the requirements.

Unreasonable mold design: can lead to unstable product structure or other quality issues. The solution is to optimize the mold design to ensure the quality of product molding. Ah

The process flow of injection molding mainly includes steps such as mold design, raw material preparation, injection molding machine operation, mold injection molding, cooling and solidification, demolding, and part trimming. Design the mold according to the shape and size of the product, then prepare the required plastic raw materials and load them into the injection molding machine for heating and melting. Next, the melted plastic is injected into the mold, and through the high pressure and constant temperature of the mold, the plastic material is fully filled into the cavity of the mold and cooled and solidified inside the mold. Demould the molded parts, perform trimming treatment, and finally obtain a finished product that meets the requirements.

Injection molding has many advantages, such as high production efficiency, good product quality, and high shape complexity. Among them, the high production efficiency of injection molding is mainly reflected in the following aspects: the high degree of automation of injection molding equipment, continuous production, and the ability to achieve high-speed production, greatly improving production efficiency. Secondly, the injection molding process is simple, easy to operate, and can achieve mass production, which can meet the needs of large-scale production.
