Material Performance & Consistency
Our ABS-like polyurethane casting material closely matches traditional injection-molded ABS in rigidity, dimensional accuracy, and functional performance - making it the ideal choice for functional prototypes and short-run ABS parts. Batch-to-batch consistency is controlled within ±2%.

Internal Test |
Based on supplier TDS and in-house testing. Our ABS-like plastic casting delivers strong tensile strength and Shore D hardness. Through optimized post-curing, the Heat Deflection Temperature (HDT) remains stable and suitable for most functional validation scenarios. Internal batch testing confirms performance variation of less than 2%.
Process Flow
ABS-like urethane casting uses silicone mold and vacuum casting processes to ensure bubble-free, low-shrinkage, smooth-surface parts. The full process can be completed in as few as 7 days.
- 7-Step Process *(factory photos recommended)*
- CAD file review and DFM optimization *(1 day)*
- Master model production (SLA or CNC machining)
- Silicone mold casting - creating high-precision silicone master molds
- Vacuum casting - vacuum-degassed urethane resin poured to eliminate bubbles
- Room-temperature / heat curing and post-curing
- Demolding and fine post-processing
- Full-scale QC inspection and delivery
The vacuum environment is essential for controlling surface finish and dimensional stability - particularly important for ABS-alternative casting material applications.

Surface Appearance
ABS-like plastic casting achieves injection-grade surface quality, supporting a full range of finishes - matte, semi-gloss, and high gloss. Color matching accurately reproduces Pantone or RAL standards, with strong detail reproduction (wall thickness as low as 0.8–1.0 mm, logo embossing, texture replication).
Surface Treatment Options
We offer a comprehensive range of post-processing services to enhance both aesthetics and functionality:
|

Application Scenarios
ABS-like urethane casting is widely used wherever functional prototypes or small batches of rigid parts are required:

Consumer Electronics Enclosures -
Phone/headphone housings with precise texture and fitment

Medical Device Panels -
Equipment panels meeting biocompatibility and appearance requirements

Automotive Interior Prototypes -
Trim panels and handle validation; qualified tensile strength and HDT

Industrial Equipment Panels -
Operator interfaces, impact-resistant and wear-resistant

Smart Home Products -
Switch panels, sensor housings

Exhibition & Display Models -
High-detail display items
Many customers successfully transition from ABS-like plastic casting directly into low-volume production.
