Auto components manufacturing

VMC control and drive retrofit

Challenge: An obsolete CNC and unreliable drives were causing repeated stoppages, while replacement spares were difficult to source.

Solution: Mektronix replaced the CNC, axis servos and spindle drive, rebuilt the ATC logic and recommissioned the complete machine.

General engineering

Conventional lathe converted to CNC

Challenge: Manual operation limited repeatability and made batch components dependent on operator skill.

Solution: The lathe was converted with ballscrews, a modern CNC, servo axes, MPG, electrical panel and a new safety circuit.

Automotive assembly

Special purpose machine automation

Challenge: Manual sequencing caused inconsistent cycle times and defects could pass without reliable poka-yoke checks.

Solution: Mektronix engineered the PLC sequence, HMI screens, sensing logic, pneumatic controls and production counters.

Process manufacturing

Legacy PLC and SCADA migration

Challenge: An undocumented, unsupported PLC created a high breakdown risk and prevented the maintenance team from making changes.

Solution: The old program was reverse-engineered, rebuilt on a supported PLC and connected to new operator and supervisory screens.
