How does PEPSEN manufacture custom polyurethane silent block?

There are many different ways to produce them, depending on hardness, quantity, formulation and tolerance requirement.

If quantity is more than 100pcs, the usual way is to mold them by casting, otherwise, machining will be more cost-effective. It will increase material waste, but will save precision tooling cost. However, there also exceptions, if hardness is lower than 70A, and the shape is not suitable for making a clamp, machining will not be available.

Sometimes formulation is another factor we need to consider, some special formulations will have special MOQ and operation procedure.
