Alternatively the resin and related materials may be mixed on site when a producer wants greater control over the chemistry and filler.
The longer fibers in SMC result in better strength properties than standard bulk moulding compound (BMC) products.
Heat and pressure act on the charge and once fully cured, this is then removed from the mould as the finished product.
Compared to similar methods, SMC benefits from a very high volume production ability, excellent part reproducibility, it is cost effective as low labor requirements per production level is very good and industry scrap is reduced substantially.
Weight reduction, due to lower dimensional requirements and because of the ability to consolidate many parts into one, is also advantageous.
