To help you choose the right manufacturing method, it's important to first highlight the differences between them. We will be discussing the differences between injection mold and urethane molding in order to make project selection easier for those who find it hard to decide what to do.
We'll be looking at almost identical processes. They may give different results depending if you have specific expectations or preferences.
Let's first look at the differences that exist between injection molding service and casting.
Differences
These are processes that, as we have seen, are nearly identical. If you dig deeper into their functions, they can be distinguished. Casting, for example, is about filling the mold cavities with the material directly. Plastic Injection molding service is where pressure is applied to the mold cavities using an specialized machine.
These two processes have a lot in common. The material that has been filled in cavities must be allowed to cool, and then it can be ejected either from mold or cast.
The other difference between these two processes lies in the type of materials used. Injection molding makes use of molds created from hardened steel or soft metals such as aluminum. Casting is made with silicone rubber.
The materials used can vary from one process to another. While casting materials can have properties similar to materials used for injection molding, these materials use materials such as ABS, PVC, or other options.
Injection molding produces large quantities of molds with larger cavities. Casting produces a smaller amount of material.
The tooling process is another difference between the two. The casting process uses 3D modeling. Injection molding uses CNC-machining type grinding.
In terms of costs, injection molding tends to be costly compared to casting. Injection molds can be very cost-effective and will eventually pay for themselves. Although casting casts can be as low as $2000, making molds using injection molding may run into the thousands.
