Process: Step-by-Step Workflow of ABS Vacuum Casting
The ABS Vacuum Casting process is a streamlined, repeatable workflow designed to maximize efficiency and minimize defects. Below is a detailed breakdown of each stage:
Step 1: Mold Preparation
First, we create a master mold (typically from silicone or aluminum) using your 3D model or physical prototype. The mold is engineered to capture every detail—from surface textures to intricate features—and is treated to ensure easy demolding.
Step 2: Resin Mixing
We blend ABS resin with specialized additives (for enhanced flexibility or heat resistance) and catalysts (to control curing time). The mixture is stirred under vacuum to remove air bubbles, a critical step for preventing voids in the final part.
Step 3: Vacuum Chamber Infusion
The mixed resin is poured into the mold, which is then placed in a vacuum chamber. The chamber is sealed, and vacuum pressure (typically -0.95 bar) is applied to draw the resin into every corner of the mold, ensuring complete filling.
Step 4: Curing Process
The mold is heated to 60–80°C to accelerate resin curing. Cure time varies by part thickness (1–4 hours for most components) and is monitored to avoid over-hardening, which can cause brittleness.
Step 5: Demolding & Post-Processing
Once cured, the mold is opened, and the part is removed. Post-processing steps (e.g., trimming excess resin, polishing) are performed to achieve the desired finish.
Materials: Choosing the Right ABS Resin & Additives
The success of ABS Vacuum Casting depends on selecting high-quality materials that align with your part’s performance needs. We source premium ABS resin from trusted resin suppliers and offer a range of additives to enhance functionality.
| Material Type | Purpose |
| ABS resin | Base material providing durability, impact resistance, and machinability. |
| Additives | Improve UV resistance, flame retardancy, or flexibility (e.g., plasticizers). |
| Fillers | Reduce cost or enhance strength (e.g., glass fiber, talc). |
| Catalysts | Control curing speed to ensure uniform hardening. |

Our preferred resin suppliers include Sabic, LG Chem, and Chi Mei Corporation—brands known for consistent quality and compliance with global safety standards (e.g., RoHS, REACH).
Surface Treatment: Enhancing Aesthetics & Performance
After casting, parts can undergo surface treatment to improve appearance, durability, or functionality. We offer a range of finishing options to match your project’s needs:
- Painting: Custom color matching (using Pantone or RAL codes) for parts requiring brand alignment.
- Coating: Protective layers (e.g., clear coat for scratch resistance, anti-static coating for electronics).
- Polishing: Achieve glossy or matte finishes, with surface roughness (Ra) as low as 0.2μm.
- Texture application: Add tactile textures (e.g., leather grain, ribbing) for grip or aesthetic appeal.
| Surface Treatment | Benefit | Example Application |
| Painting | Brand consistency, UV protection | Automotive interior parts |
| Coating | Scratch resistance, chemical resistance | Medical device housings |
| Polishing | High-gloss finish, improved light reflection | Consumer electronics casings |
| Texture application | Enhanced grip, reduced fingerprint visibility | Tool handles, remote controls |
Tolerances: Ensuring Dimensional Accuracy
Dimensional accuracy is critical for parts that need to fit or function with other components. Our ABS Vacuum Casting process achieves industry-leading tolerance levels, supported by advanced measurement tools and strict quality control.
Key Tolerance Specifications
- Linear tolerance: ±0.1mm for parts up to 100mm; ±0.15mm for parts 100–300mm.
- Geometric tolerance: Flatness ≤0.05mm/m, parallelism ≤0.1mm/m.
- Precision measurement: We use coordinate measuring machines (CMMs) and laser scanners to verify dimensions, ensuring compliance with ISO 8015 (geometric tolerancing) and ASME Y14.5 standards.
| Part Size (Length) | Linear Tolerance | Measurement Tool |
| <100mm | ±0.1mm | CMM (accuracy: ±0.005mm) |
| 100–300mm | ±0.15mm | Laser scanner (resolution: 0.02mm) |
| >300mm | ±0.2mm | Optical comparator |

Advantages: Why Choose ABS Vacuum Casting?
ABS Vacuum Casting offers a unique blend of benefits that make it ideal for prototyping and low-to-medium volume production. Here’s how it outperforms other manufacturing methods:
- Cost-effectiveness: No expensive metal tooling—silicone molds cost 70–80% less than aluminum molds, making it ideal for small runs.
- High precision: Captures fine details (down to 0.1mm) and achieves tight tolerances, reducing the need for post-processing.
- Short lead times: Molds can be ready in 2–3 days, and production runs are completed in 3–7 days (vs. 4–6 weeks for injection molding).
- Customization: Easy to adjust resin properties (e.g., color, flexibility) or mold designs for iterative prototyping.
- Durability: ABS parts resist impact, heat, and chemicals, making them suitable for end-use applications (not just prototypes).
| Advantage | ABS Vacuum Casting | Traditional Injection Molding |
| Tooling cost | Low (500–5,000) | High (10,000–100,000+) |
| Lead time | 3–7 days | 4–6 weeks |
| Volume flexibility | 10–10,000 units | 10,000+ units |
| Customization ease | High (quick resin/mold adjustments) | Low (expensive tooling changes) |
