When we talk about vacuum casting, we usually compare it with injection molding. So, let’s distinguish the difference between them first.

Vacuum Casting Vs Injection Molding

 Let’s take the mobile phone case as an example, the mold of the vacuum casting service is only tens of dollars, while injection molding costs thousands of dollars. On the other hand, the production fee of vacuum casting service is tens of dollars per unit, while injection molding only costs 1 or 2 dollars.

In brief, vacuum casting service has a lower front-end cost and a higher unit price, while injection molding requires a higher front-end cost, but the unit price is significantly lower。

Vacuum  Casting Vs 3D Printing

Compared with 3D Printing（3DP), what’s the advantage of vacuum casting? Base on the same material, vacuum casting service has higher smoothness, durable, and accuracy, and it has not limitation to the color as well. 

Vacuum Casting Vs CNC Machining

It is difficult to say which one is better, but if we consider the complexity of the prototype, production efficiency, and cost, vacuum casting will have more advantages. While the CNC has more material options, the material performance is better.

Being able to make soft materials quickly is one of the biggest advantages of vacuum casting. It supports materials from Shore 30A to Shore 95A, from Shore 10D to Shore 90D, in any customized Pantone No.

In conclusion, vacuum casting service is not in conflict with and can’t replace other technologies, Instead, it is a supplement way, providing more flexible solutions for manufacturing.
