AI Technical Summary
Technical Problem
In the process of recycling plastics to produce electrical knobs, the knobs tend to stick to the ejector pins, making demolding difficult and affecting production efficiency and product quality.
Method used
A rotating component drives the ejector pin to rotate. Combined with a lifting component and a moving component, this achieves reliable separation between the ejector pin and the knob. An anti-foaming component eliminates air bubbles in the melt, ensuring molding quality.
Benefits of technology
It improves demolding smoothness, reduces manual intervention, lowers the risk of product scratches and deformation, and increases production efficiency and product qualification rate.
