Smart Robot Casing Back Cover: Inverted Submerged Angled Ejector Gate Solution – T1 Mass Production, Flawless Aesthetics, Optimized Cost
Product Requirements:
The product has large dimensions with a textured (grained) cosmetic surface. It is produced as a bare substrate without painting or plating.
Product Overview:
The product material is flame‑retardant ABS V0 grade. Dimensions: 247 × 428 × 89 mm. The front face is the cosmetic surface and no visual defects are allowed.
Mold Solution:
Based on the product features, the mold was designed with a special inverted submerged angled‑lifter gating system. This achieves a defect‑free product appearance (no sink marks on the product surface, no sink marks or stress marks on the opposite side of the gate, no long thin weld lines, etc.) and minimal product warpage.
Result Feedback:
The mold achieved mass production readiness at T1. This ingenious mold structure design saved costs for the customer (the customer had originally planned to use a painting process to cover cosmetic defects). The customer is very satisfied.
