When it comes to finding the best silicone company it is important to ensure that one settles for the most suitable one which offers the best advices on the most suitable silicone molding process to go for. Considering the fact that there are three molding methods that are available it can be difficult to settle for the most perfect one especially if one does not have an idea of their differences.
LMI which is also known as liquid injection molding is one of the best and most advantageous processes to go for because it is extremely fast and also very clean. This process uses a clean silicone liquid that is used for the pumping process. The pumping system is usually used to deliver the liquid silicone that has two parts namely the cross linker and the catalyst into the mixer directly. This is usually injected directly into the cavity of the mold and this is done in a process that is completely closed. This is the reason as to why contamination is difficult to occur and other particulates are also easily avoided. There is also very little interactions of humans and this enables the variation process to be improved highly.
There are also the transfer molding and the compression silicone molding processes that are commonly utilized. Although these processes are usually not utilized as much as the LMI process they are not so badly off. The transfer molding uses the hydraulic ram to replace the rubber into the cavities through the spurs and the gates. This however is different from the compression process because the rubber is usually placed physically into the cavities and then the fill is completed by the closing action. These processes usually require more labor and there is also the premixing of materials. These processes usually take longer than the other and that is why they are not highly preferred.
The third molding process is the micro molding process and this is very rarely used. This is because it is very small and the process is also highly complex. This requires a company that has experience with the best use of clean silicone so as to get the best products out of it. It is therefore important to have a company that knows all about these processes to offer the best.
