SMC technology advantages
The technology is most often used for series production ranging from hundreds of pieces per year to tens of thousands of pieces per year.
SMC is a material base for a very wide range of applications
Glass fibre content 25–50%.
SMC enables the moulding of complicated parts in a fast production cycle
The cycle for a large part takes about 5 minutes. Suitable technology for series of 10–100 thousand parts per year.
SMC enables the production of parts with bosses, ribs and inserts
We can automate the whole process, including finishing.
Stability of parts
Parts manufactured using SMC technology are characterized by their high rigidity, dimensional stability when hot and low thermal expansion.
A wide range of finishing options
IMC technology can be used in combination with powder coating for priming, whereby parts can be coloured “en masse” with “A” surface quality.
How is SMC material processed?
Sheet Moulding Compound (SMC) is a composite semi-finished product composed mainly of thermosetting resin (usually polyester) and chopped glass fibres, which is produced in the form of sheets. Parts of a required size can be cut from these sheets, which are then formed into the desired shape at elevated temperatures and pressures in a moulding machine. During compression, a number of polymerization and cross-linking reactions take place.

SMC and glass fibres
SMC technology allows the use of materials with a fibre content (glass, carbon, etc.) of between 15% and 65%.
The length of the fibres is usually 25 or 50 mm, but it is also possible to produce SMC with fabrics or continuous fibres. Mineral fillers, thermoplastic additives, catalysts, inhibitors, separators, viscosity modifiers and pigments are used to improve the final properties of the product and the moulding process.
Types of SMC technology according to reinforcement
- -R- with randomly arranged fibres,
- -CR- with continuous fibres, randomly arranged,
- -XMC- fibres are arranged at an angle.
