The Challenge of Making the Large parts in the Automobile Industry the Solutions such as SMC – Sheet Moulding Compound and BMC – Bulk Moulding Compound are used regularly . The excellent part reproducibility, it is cost effective as low labor requirements per production level is very good and industry scrap is reduced substantially
These compounds are Moulded at High temperature and High Pressure so that a Final Shape of the Component has been made with high Geometrical Accuracies . The Weight of the final component is lighter as compared to the components made from Steel and Aluminum and . The Components made from SMC / BMC Compound also has the capability to resist heat and Provide the Strength , Mechanical Integrity as compared to Thermoplastics .
SMC and BMC are mixtures of resin, fillers and reinforcement, processed in heated mold to form a cured component. SMC is a sheet consisting of uncured resin reinforced with glass fibers, which is laid into the mold and compression molded. BMC is a bulk mixture of uncured resin reinforced with glass fibers, which is injected into the mold.
SMC has longer fiber length than BMC and a higher fiber content, resulting in greater flexural strength and tensile strength. SMC is used for larger flat parts, components with higher structural requirements, and parts that need good cosmetics. Parts where SMC is used include automotive body panels, building façade panels, deck lids, and electrical cabinet etc.
