What is PC/ABS Injection Molding?
Our PC ABS injection molding process combines the toughness of polycarbonate (PC) with the flexibility and processability of ABS. This results in components with superior impact resistance, heat tolerance, and dimensional stability.
- Mold Design: Optimized mold flow and cooling channels reduce warping and ensure tight tolerances.
- Processing: PC-ABS materials blend is melted and injected at high precision, ideal for complex geometries.
- Cooling & Solidification: Controlled cooling avoids internal stress and maintains part integrity.
- Post-Processing: Finishes like texturing, painting, and EMI shielding enhance performance and aesthetics.
With our experience in custom PC/ABS molding, we provide reliable solutions for demanding environments and performance-critical PC-ABS parts.

PC ABS Material Properties
PC-ABS injection molding is widely used for durable, heat-resistant parts with excellent toughness and impact strength. The blended properties make it a preferred material for structural parts and enclosures. Key material properties:
- High impact resistance – Ideal for enclosures and crash-resilient parts.
- Excellent heat resistance – Maintains shape and performance up to 100–120°C.
- Good dimensional stability – Resists shrinkage and deformation.
- Paintability – Excellent surface finish for cosmetic applications.
| Property | Density | Tensile Strength | Flexural Strength | Impact Strength (Unnotched) | Heat Deflection Temp (0.45 MPa) |
|---|---|---|---|---|---|
| Value/Description | 1.10 - 1.20g/cm³ | 40 - 65 MPa | 70 - 120 MPa | 10 -40 kJ/m² | 95 - 115℃ |
- The above parameters represent the baseline performance of the materials. Actual application should be dynamically optimized based on specific working conditions.

Jiangzhi PC/ABS Injection Molding Service is Guaranteed
PC/ABS offers a balanced compromise by providing greater strength and heat resistance than ABS, easier processing and less brittleness than pure PC, and a better surface finish compared to pure PC.
It blends PC’s strength and ABS’s processability, creating impact-resistant, heat-tolerant housings with great surface finish—ideal for electronics, tools, and automotive parts.
PC/ABS is hygroscopic. Moisture can cause bubbles, poor surface finish, or internal voids. Dry at 80–100°C for 3–4 hours before molding.
PC/ABS is suitable for both overmolding and two-shot injection molding. Its good flowability, strong adhesion properties, and balanced mechanical strength make it an excellent choice for multi-material molding processes.
