Engineering Overview:
Our engineering focus centered on warpage control for the large-diameter circular geometry, utilizing symmetric gate placement to balance internal stresses. This ensures the component maintains perfect concentricity for seamless ultrasonic welding or snap-fit integration with the bottle body.
Technical Specifications & DFM Insights:
We optimized the rib-to-wall thickness ratio to eliminate sink marks on the aesthetic outer surface while maintaining rapid cooling cycles. The mold utilizes high-grade stainless steel with specialized venting to prevent gas burns during high-volume PP injection.
