Some materials are very expensive, but on small complex parts the material cost may not be that significant. However, on tiny, thin parts, the weight of flash, sprues and runners may be large compared with the component itself.
Each mould is made to allow for the shrinkage of a specific compound. Rubber compounds of the same type have similar shrinkages – harder compounds shrink slightly less. It is possible to change compounds in a mould but the finished dimensions may vary if the shrinkage is different.

"McCafferty BM Design Ltd, KENT United Kingdom" - Most of the O rings manufacturing company suggested to use larger diameter and expensive elastomers. We learnt with Mech Spares that elastomer being weaker compare to metal and alloys and needs appropriate back up for high pressure or high vacuum applications. Further not necessary the most expensive elastomer is the best for all applications. We trust Mr Nilesh chodhari completely for all our O rings designing applications.
