Flow marks are common surface defects of plastic parts near the gate, which appear as a wavy mark and present a concentric circle centered on the gate. Flow marks are usually caused by uneven temperature distribution of plastic parts during the molding process or too fast plastic solidification. In addition, during the melt flow process, […]

abs plastic molding manufacturers before molding, plastic must be fully dried. When materials containing water enter the mold cavity, silver ribbon-like defects will appear on the surface of the product, and even hydrolysis will occur at high temperatures, causing material degradation. Therefore, the material must be pre-treated before molding so that the material can maintain appropriate […]
I. Injection mold 1. Poor mold cavity processing If the mold cavity has scars, micropores, wear, roughness and other deficiencies, it will inevitably reflect on the plastic parts, making the plastic parts have poor gloss. For this, the mold should be carefully processed to make the surface of the cavity have a smaller roughness, and […]
For an Electronic product shell processing factory, the energy consumption of the injection molding process accounts for about 60%, so effectively reducing the energy consumption of injection molding machines is an important way to save energy in injection molding factories. With the continuous improvement of the energy-saving technology of injection molding machines themselves, reducing the […]
