Advanced Plastic Housing Frame Injection Molding

Category

Specification & Engineering Requirements

Product Name

Custom Structural Housing Frame / Chassis

Primary Process

Injection Molding (Optimal for complex geometries, strength, and volume)

Core Function

Structural Support, Component Integration, Assembly Backbone, EMI/RFI Shielding (if metalized)

Key Priorities

1. Rigidity & Strength: Must resist bending and torsional forces.
2. Dimensional Precision: Critical for component alignment.
3. Assembly Features: Integration points for screws, snaps, and other parts.
4. Thermal Management: May include heatsink mounts or airflow channels.

Top Material Choices

1. ABS: Best all-rounder. Good strength, stiffness, and cost. Easy to mold.
2. PC (Polycarbonate) or PC/ABS Blend: Superior impact resistance and heat tolerance (up to ~125°C). For demanding applications.
3. PA66 (Nylon) with Glass Fiber (GF): For maximum strength, stiffness, and heat resistance. Best for structural frames bearing heavy loads. (e.g., 30% GF content common).
4. PP: For lightweight, chemical-resistant, and low-cost frames where flexibility is acceptable.
