Vacuum Casting Rapid Prototyping Of Small Production Runs For ABS Polyurethanes
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.
Industries involved:
Robotics,UAVS(unmanned aerial vehicle),Medical equipments,Plastic enclosure,Eletrical products,Phone case,auto parts,Household appliances,Sporting equipments,Military,etc.
Benefits Of Vacuum Casting
Vacuum casting offers efficient manufacturing of intricate shapes with high precision, cost-effectiveness, and versatility:
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. |

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.

FAQ:
Choosing vacuum casting over 3D printing hinges primarily on material quality and performance.
Vacuum casting offers superior materials that closely replicate those found in commercial products.
If material performance and product aesthetics are paramount, opt for vacuum casting.
As vacuum casting can be used for low volume production as well as mass production, it is applied by various industries such as consumer products, food and beverage, electronics, and etc.
Vacuum casting is best for making visually impressive prototypes, but it can also be used for non-mechanical end-use parts.
