MATEC has the capability to provide extensive assistance to its customer: from project conception, design engineering and implementation to after-sales repairs, maintenance and operator training.

In power generation, it was actively involved in the rehabilitation works of the Malaya and Sucat Power Plants of National Power Corp. Together with its subsidiary Trans Orient Overseas Corp. (TOOC), MATEC has a proven track record in giving support to both its customer and principal in project management, manpower deployment and logistical services.

Since the early 80's MATEC has gained the experience in the turnkey installation, commissioning and after sales service work of base load diesel generating sets in several islands of the Philippines.
It currently handles the operation, maintenance and service of diesel gensets providing 12 MW of temporary power to Southern Electric for their Sual Power Plant Project.

MATEC has the expertise to design, engineer and render construction supervision for a complete power substation including erection works of steel structures and the installation and commissioning of accessories. It makes full use of the skills of its Filipino engineers who offer value-added service to imported equipment through local fabrication works at its switchboard manufacturing corporation (NI), installation supervision and commissioning as well as after sales service, maintenance and repair work.

Process control system is the trend in modern industrial and commercial plants. MATEC has highly trained process control engineers capable of designing application software for micro processor based process controllers, installing and commissioning process control equipment and accessories plus application software and hardware fault detection and correction. It can also provide full operator training for its customer's personnel.

Complementing MATEC's activity in the electronic automation field, Philippine Electronic Industries (PEI), a wholly owned subsidiary of MATEC, offers warranty fault detection repair and calibration services for users of Tektronix testing and measuring instruments. Filipino technicians who underwent extensive training abroad perform these services utilising instruments certified by the National Institute of Standards and Technology. Services for its customers also include classroom, formal group or individual training seminars conducted by highly trained sales engineers.

The communication field has long been one of the company's major fields of endeavor. Due to MATEC's service philosophy offering the customer turnkey installation and after sales service fully supported by service personnel trained abroad as well as sparepart management, MATEC became the leading supplier of PABX in the early 90s. Its service capabilities range from repair, service and maintenance of airline reservation systems and Gentex systems to emergency call boxes as well as simple telephones.
