Abstract
The present invention concerns a method, according to which powder compositions of iron-based particles are admixed with a thermoplastic material and a lubricant. The obtained mixture is compacted at a temperature below the glass-transition temperature or melting point of the thermoplastic resin and the compacted product is heated in order to cure the thermoplastic resin. Subsequently, the obtained compacted component is optionally heated to a temperature above the curing temperature.
