Customer: L’Oreal (Wales)
Date: November 2001
Container: 92mm Diameter PP
Output Requirement: 3000 containers/hour
Machine Type: 3 Head automatic foil cutting and sealing machine using tool steel punch & die sets, transferring to induction sealing heads with vacuum foil retention for foil location. Relco ICS-1G induction generators, Mitsubishi Fx series PLC, Mitsubishi inverters and controls, SMC pneumatics.
Technical Challenges: Customer container and cap not suitable for conventional (foil lined cap) induction sealing due to insufficient down-force from closing torque of cap to ensure even sealing pressure across entire diameter of seal. Machine required to locate and directly induction seal foil onto container before the application of cap. Reel feeding of material more convenient, cheaper and longer running than magazine feeding so machine designed to work using a web of foil, cutting into the correct profile then transferring onto container. Machine installed and gave excellent results helping the Llantrisant plant win first place in the annual world-wide L’Oreal competition for production engineering excellence.
Post Script: Following successful installation at the Llantrisant plant, further identical machines were built and supplied to L’Oreal factories in Poland and Mexico.
