Cracks, narrow fissures appearing on injection-molded parts, can stem from issues with the injection molding machine, mold, molding process, and raw materials.

In the field of injection molding, a phenomenon known as "silver streak" often plagues manufacturers. It manifests as silver-white stripes on the surface of injection-molded parts, actually left by low-molecular volatiles, water vapor, and other gases during the molding process.

Flow marks in the world of injection molding are like unexpected "imprints" that quietly appear on the surface of plastic parts. Their root cause lies in the subtle interaction of injection pressure and flow speed within the mold cavity. Today, let us together uncover the mystery of flow marks, delve into their causes, and explore effective solutions.
