Vacuum Casting Rapid Prototyping And Silicone Rubber Injection Molding Parts
Vacuum Casting :
Vacuum casting is a swift, budget-friendly method for replicating top-notch plastic parts, akin to injection-molded items. It employs dual-component polyurethanes and silicone molds crafted from a 3D-printed prototype. This approach is ideal for testing fit and function, marketing needs, or producing limited runs of final-use components.
1.Rapid prototyping
and full-scale production
2.Used in over
30 countries
3.ISO 9001 accredited
& QC checks
The advantages of Urethane Casting:
- Suitable for Small Production Runs
- Achieves Consistent Self-Colored Parts
- Minimal InitiaInvestment Required
- Delivers Production-Quality Components
- Wide Array of Material Options
- Enables Creation of Rubber-Like Parts and Over molds
Urethane Casting Tolerance Guidelines:
| Maximum build dimensions | The size of the mold is limited by the dimensions of the vacuum chamber (1,900 x 900 x 750 mm) and by the volume of the product (maximum volume: 10 liters). |
| Standard accuracy | ±0.3% (with a lower limit on ±0.3 mm on dimensions smaller than 100 mm). |
| Minimum wall thickness | At least 0.75 mm to ensure the mold is filled properly; for best results, wall thickness of at least 1.5 mm is recommended. |
| Surface structure | High-quality surface finish comparable to injection molding. |
| Part size / dimension | Tolerance | Angularity |
| < 11’’ (300 mm) | ± .005’’ (0.125 mm) | ± 0.5° |
| < 24’’ (600 mm) | ± .010’’ (0.250 mm) | ± 1.0° |
| < 36’’ (900 mm) | ± 1/16’’ (0.400 mm) | ± 1.0° |
Size limitations for Urethane Casting:
Requirement | Specifications |
Maximum part dimensions | 1700 x 700 x 850 mm |
Minimum wall thickness | 0.65 mm (recommended wall thickness 1.5 mm) |
Duplication quantities | 10-20 copies (depend complexity of the mold and casting materials) |
Vacuum Casting Process
Creating polyurethane vacuum cast parts involves three main steps: master pattern creation,
mold fabrication, and part casting.
1. Master Pattern Creation:
Crafting patterns from your CAD designs is the initial step. These 3D solids are made through CNC machining or 3D plastic printing like SLA/SLS. You can provide patterns or let us create them. Patterns should endure up to 50°C heat.
2. Mold Fabrication:
Liquid silicone forms the casting molds. It's poured around the master pattern within a casting box, cured in an oven for 15 hours. Afterward, the mold is opened, and the master pattern is removed, yielding a negative cavity mirroring the original. Our silicone molds typically yield around 25 copies of the master pattern.
How does vacuum casting work?
The process involves 3 main stages:
- Building a master model
- Creating the silicone tool and
- Producing the parts
Building a master model: To achieve precise results in vacuum casting, start with a top-notch master model. Crafted via 3D printing or CNC machining, it's meticulously refined for ideal surface texture and detail replication. | |
Creating the silicone mould tool: Create precise silicone molds by encasing the master model in a casting box filled with liquid silicone. Maintain a 40°C temperature for 8-16 hours until the silicone sets. Once cured, cut open the mold to reveal a perfect fit for your master model. | |
Producing the parts: Fill the hollow mold with polyurethane (PU) resin through a funnel to ensure even distribution and prevent air bubbles. Seal the mold and let it cure at 70°C in a casting machine. After cooling, remove the shaped material, and perform any required post-processing. Typically, this process can be repeated 10-20 times before the mold's shape starts to deteriorate, affecting accuracy. |
