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:
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° |

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:
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.
