BASE RR DOOR TRIM RH/LH

Overview
This mold features 1‑out‑2 cavity layout, specially developed for automotive HVAC air ducts.
HVAC duct parts are large curved hollow plastic components for vehicle air‑conditioning systems. Parts have thin wall thickness, long flow paths, complex bent contours, and strict requirements for air‑tightness & dimensional stability.
Poor venting and unbalanced cooling easily cause short‑shot, burn marks and warpage which will lead to air leakage after assembly.
Our duct molds adopt targeted venting strategy and conformal cooling design to solve these typical industry challenges.

Molded finished parts:
‑ Instrument panel HVAC air ducts
‑ Heater & ventilation housings
‑ Air distribution ducts for automotive climate system

Design Advantages
1. Segmented insert cavity design
2. Targeted multi‑section venting system
3. Conformal following cooling layout
4. Optimized gate location for duct characteristics
5. Reasonable shrinkage compensation for hollow duct
6. Reliable ejection mechanism for irregular hollow parts
