Silicone injection
Injection molding of flexible parts can be easily carried out on conventional presses from a variety of elastomer grades, and is an economical and effective solution in many cases. This is a thermoplastic process, since plastic is melted and then molded into a tool, which gives it its final shape after cooling.
Sagaert, of course, manufactures an infinite number of flexible parts in this way.
However, in many technical applications, and in particular when the components produced have to withstand heat, cold, or very demanding mechanical cycles, such as aeronautical seals, flexible food moulds, certain silent-blocks, or even watch straps, only "silicones" and polyurethanes can be used.
meet specifications.
The industrial process is the reverse of the previous one: a cold but liquid material is injected into a mold, often in bi-component form, and it's the reheating in the mold that permanently "sets" the shaped material - you're in the world of "thermosets"... It's more complicated, the equipment more sophisticated, the technical challenges more daring, but at SAGAERT, we love silicone parts!
Our equipment enables us, of course, to mold silicone parts in very large runs, but - and this is of great interest to our customers - we can also work on mini-production runs, or even single parts when development ... or the end market requires it.
