Schunk Sonosystems‘ MINIC-II-plus Ultrasonic Welding System is a cut-edged system for the production of cables or conductors into complex assembly lines. Wire cross-sections up to 30 mm2 can be welded, depending on the generator output power. Compact design offers a wide range of application possibilities. For example, the system can be set up as a panel unit or as a component for special purpose settings such as circuit breakers.

In the repair and maintenance of ultrasonic welding machines for metal, aluminum, copper, and industrial glass, CTI SUPPLY’s engineering team conducts customer support tasks such as:

  • Check, repair and do maintenance for the series of MINIC-II-plus, MINIC-II-GT, MINIC-II-CS, DS20,etc.
  • Do troubleshooting and adjust the sensor reference position
  • Check and adjust the mechanical factors in the machinery system

Welding systems ranged for the wire harness industry, ultrasonic pipe clamps, airtight sealing of cooling systems and particularly complex systems for the solar, electronics, semiconductor and battery production industries.

Laser Shaft Alignment

CTI SUPPLY implements laser-based shaft alignment projects for large-load motor drive systems such as crushers, generators, industrial fans and pumps in  manufacturing industries such as paper mills, steel, cement and fertilizer.

In particular, the team completed the motor balancing item for a number of paper mills nationwide. According to requirements of the factory, CTI SUPPLY does an actual assessment phase of the machine and carry on the laser alignment.

  • Clean the machine and motor base
  • Mount and test to identify the deviation via laser aligning device
  • Install the vertical and the horizontal aligning shim

Among these plants used the large motor drive system, the problem solving of motor shaft misalignment ensure production progress, minimize machine downtime and saving spare parts costs and energy.

Overhaul Maintenance in Hardening and Tempering Furnace

An Industrial Hardening and Tempering Furnace is a complex system with several working chambers in the harsh environment. It can’t be denied that regular maintenance for this type of machine is a must.

In a continuous conveyor system, products are placed in baskets and move through the inner furnace including 4 chambers: Washing 1 – High Temperature Oven (HTO) – Oil Quenching – Washing 2 – Low Temperature Oven (LTO). For overhaul maintenance of a hardening furnace, CTI SUPPLY implements a set of procedure:

  • Disassembling
  • Cleaning and calibrating equipment
  • Checking conditions of process control and heating system, moving parts and electrical system
  • Replacing worn out and out-of-order items
  • Cleaning and reinstalling the parts of the furnace
  • Final safety check before handing over

Overhaul maintenance for the Hardening and Tempering Furnace is a high load labored process and requires lots of engineering maintenance knowledge. Nevertheless, CTI SUPPLY offers such maintenance services with sufficient schedule for customers to attain the downtime reduction, cost savings and workhour avoidance.
