With a long roster of powerhouse customers - including Cisco, Intel, Sony, Toshiba, LG, Samsung and Pegatron - the Concraft Group is known for its commitment to highest innovation in pursuit of precision and productivity. That is why Concraft increasingly turns to GF Machining Solutions’ Electrical Discharge Machining (EDM) solutions for renowned performance, flexibility and ease of use.
Based in Taiwan, Concraft employs about 1,900 people in China and Singapore, Concraft was founded in 1991, specializing in the design and production of connectors for the electronics industry.
New machines installed In the past three years, Concraft has accumulated a fleet of 13 GF Machining Solutions EDM machines. Among them are four FORM 20 die-sinking EDM machines. “The outstanding price/performance ratio offered by the Form 20/Form 30 range makes it a natural choice,” said General Manager Agi Lee. “Quality and performance are particularly important to us. In our EDM machines, we always expect high respect for details, homogenous surface quality, and ability to handle small radii. We check the radii by micro-scope, and we also do quality checks with coordinate measuring machines.”
Intelligent solution In its molding division, Concraft successfully confronts product tolerances under 0.01 mm and the challenges of producing mold inserts - one of the group’s areas of expertise - with as many as 32 cavities for connectors and 520 cavities for light-emitting diode (LED) frames. Such exacting constraints and high demand leave no room for error. That is where the Form 20/Form 30 range makes another valuable contribution. Its AC Form human-machine interface (HMI) generates the appropriate machining strategies for Concraft’s applications, and automatically organizes the machining flow based on those strategies. The Form 20/30s’ Swiss-made generator offers continuous pulse optimization to reduce electrode wear and ensure fast process control. And all of that on-board machining exper-tise is at the touch of the operator’s fingertip, with interactive graphical assistance and embedded documentation making the machine easy to use.
