The Usage of 3D Printing Prototyping in The Designing Process of Injection Mould

    Injection Moulding Injection moulding involves filling a mould with melted thermoplastic material which then cools and hardens to form parts and components. This method is highly efficient for high-volume production due to its ability to produce large quantities of parts quickly and wit... Read More

Solutions to Enhance Transparency in Injection Molded Transparent Plastic Parts

In the process of injection molding transparent plastic parts, insufficient transparency may occur due to reasons such as low material temperature, poorly dried raw materials, melt decomposition, uneven mold temperature, or poor mold surface polish, which affects the use of the plastic parts. Th... Read More

Plastic Injection Molding Defects: Sink Marks and Their Remediation

1. Phenomenon of the Defect** During the injection molding process, certain regions of the mold cavity may not experience sufficient pressure. As the molten plastic begins to cool, areas with larger wall thicknesses shrink slower, generating tensile stress. If the surface rigidity of the molded p... Read More

Understanding Black Streak in Plastic Products: Causes and Solutions

“Black streaks,” also known as “black lines,” refer to the black-colored streaks or lines that appear on the surface of plastic parts. The main cause of black streaks is the thermal degradation of the molding material, which is common in plastics with poor thermal stabilit... Read More
