About Us

Your trusted partner in electric motor rewinding and repair since 1960.

60 Years of Engineering Excellence

GEF Technologies Sdn. Bhd. traces its roots to 1960, when it was founded in the Klang Valley as Syarikat Weng Hin Electrical Works by Mr Cheong Kah Hin, one of Malaysia's earliest specialist motor rewinding workshops. Over nearly four decades the company built a reputation for rewinding low-voltage electrical machines, serving various industries across the region.

On 1 January 1999 the business was restructured into a private limited company under the name GEF Technologies Sdn. Bhd., with Ir. KT Cheong taking the helm as Managing Director. The restructure enabled the company to expand into the full-scope repair and servicing of high-voltage and large AC and DC motors, transformers, generator and alternator.

Today, GEF operates from its well-equipped Sungai Buloh workshop. The company holds ISO 9001:2015 certification, is a full member of the Association of Electrical and Mechanical Trades (AEMT), and is also a certified service partner of ELIN Motoren GmbH, Shanghai Electric, and Sicme Motori in Malaysia.
