Injection Molding Advantages And Disadvantages
What is Injection Molding used by rubber mold manufacturers?
Injection molding is one of the most common and widely used manufacturing processes by Rubber Mold Companies that are responsible for countless parts used in so many different applications and the industrial sector. However, it’s not the only molding process, and frequently people wonder if it’s the best option for their needs. There are advantages and disadvantages, and let’s take a look at both.
The process used by rubber mold making company
First, let’s look at what the process is all about. Injection molding uses a molding press that directly closes and locks the mold by a Silicone Mold Manufacturer. Once the uncured rubber is pre-heated in an injection chamber, it is “plasticized” to flow easily through the injection system and cavities, which raises curing temperatures and shortens the curing cycle in Rubber Mold Making Company. The injection press’s clamping force keeps the mold tightly closed during the cycle, which will result in maintaining tighter tolerances and less flash.
Advantages of injection molding by rubber mold manufacturers include:
- Shorter production cycles than other methods (transfer molding, compression molding) as a result of higher clamping/injection pressure from the curing temperature
- High clamping pressure on the mold means the parts have little to no flash, as compared to the other methods
- Higher production rates lead to lower unit costs
- Oftentimes parts do not need additional finishing processes
- Automatic processes of the machine reduce labor costs
Disadvantages of injection molding include:
- In order to be practical, larger production runs are necessary for Rubber Mold Companies
- Initial tooling costs are higher than the other methods
- There are some design restrictions, so not all compounds or durometers are suitable for Rubber Silicone Extrusion
As you can see, there are many advantages to injection molding, but there are also restrictions, so other processes can also be considered for required results and one must consult the expert.
