Self Bonding

Self bonding material is latest technology where no requirement for any additional process to clit the Stacks even it is helpful to increase efficiency of the core electrically.

After the laminations have been punched, they are thermally bonded in a two-step bonding process.

Phase 1: Softening of the bonding varnish layer. Complete melting in phase 1 results after complete chemical reaction in high bonding strength and a high level of resistance to a variety of different media.

Phase 2: Further increase in temperature. The self bonding varnish hardens and becomes a stable, highly cross-linked duroplast with high viscosity and high bonding strength between the laminations.
