By pressing and coating in a single step, costly subsequent coating is no longer necessary.
Your added value is increased, the total costs for your customers are decreased and the quality of the SMC/BMC components is improved. The expense for technical retrofitting is low.
The powder coating of SMC/BMC can be easily integrated in the pressing process. The powder coating is sprayed into the pressing mould manually or automatically. The highly reactive coating hardens in a few seconds so the SMC/BMC can be laid in immediately and pressed. The cycle time is only extended by the duration of the powder coating application (depending on the component, approx. 30 sec.).
After pressing, the finished, coated component can be demoulded as usual. The typical fibre marking is completely levelled out by the PIMC process, the parts are given a highly resistant and very homogeneous surface.
The powder coatings suitable for PIMC are based on unsaturated polyester resins.
The melting behaviour is set in such a way that the coating initially has extremely low viscosity when heat is applied and then gains hardness and resistance very quickly. This ensures optimal wetting and excellent properties of the finished product.
