1. Introduction
Glass Encapsulation is the process of enclosing sensitive components within a glass-based protective shell. With a base composition of 98% silicon dioxide and 2% performance additives, cured at 120 °C for 10 minutes or UV-exposed for 60 seconds, it delivers a minimum tensile strength of 80 MPa and adhesion over 5 MPa. Engineered for harsh environments, Glass Encapsulation is ideal for Automotive rubber parts and Automotive TPV parts, and excels when applied to Automotive EPDM parts. It integrates seamlessly with 2K molds and over molds to meet the exacting tolerances of modern automotive assembly.
2. Process Workflow
Step 1: Surface Preparation
- Clean substrates to ISO 5 standards before processing Automotive rubber parts, Automotive TPV parts, Automotive EPDM parts.
Step 2: Masking & Mold Alignment
- Employ precision tooling in 2K molds and over molds to position components within ±0.05 mm.
Step 3: Glass Application
- Apply a uniform 50–200 µm liquid glass layer over Automotive rubber parts, Automotive TPV parts, Automotive EPDM parts.
Step 4: Curing & Inspection
- Final curing cycle validated for automotive-grade resilience: Automotive rubber parts, Automotive TPV parts, Automotive EPDM parts, 2K molds, and over molds pass humidity and salt-spray tests to ASTM B117.
