SMC - Sheet Moulding Compound

SMC ( Sheet Molding Compound )

It is a sheet shaped hot press molding compound formed by a thermosetting resin matrix containing glass fiber as reinforcement material, filler and additives between two films on an SMC machine.

Depending on the finished product specifications, SMC is produced with the glass fiber 25 mm lengths and the fiber amount of the total weight is % 20 – 50. SMC is molded at under pressure with heat and the final composite product becomes a material with low water absorption, high chemical resistance, high mechanical strength and lighter than metal.

Immediately after SMC production, it requires a thickening period. The storage temperatures should be within the range of 18°C to 25°C. Shelf life varies between 1 to 3 months depending on the gas permeability of the film used in production. In addition, the shelf life of the product decreases at temperatures higher than the storage specification.

Sheet Molding Compound (SMC) is a fully integrated composition ready for molding, combining reinforcement materials, resin, fillers, catalysts, mold release agents, and other additives to extend shelf life. SMC is designed by our R&D team depending on product expectations, can be designed according to the desired RAL code, flame retardancy class, fiber ratio, and UV resistance.

As molding time, pressure, and temperature vary according to part dimensions and SMC content, technical support is provided to our customers for molding.

Our SMC sheets are produced in thicknesses ranging from 2 to 4 mm and up to 150 cm width. They are either laid out in standard boxes or shipped in coil form.

Our company has a production capacity of 2,000 tons of SMC per month with two Schmidt&Heinzmann machine, equipped with automatic dosing system.
