Automotive Components Manufacturing (ACM)

With the success of Ingress Engineering Sdn. Bhd. and Ingress Precision Sdn. Bhd. in the Malaysian automotive car components market and the healthy growth for demand for car components in the region as well as in the global market, the Ingress Group ventured regionally and established Ingress Autoventures Co. Ltd., Thailand (Ingress Autoventures) a joint-venture company between Katayama Kogyo Co. Ltd., Japan (Katayama) and Ingress Group. Together with the strong technical know-how of its strategic partner, Katayama, and the proven track record and industry experience of Ingress Group, Ingress Autoventures has grown manifold and today is one of the key manufacturers of door sash, co-extruded mouldings, weatherstrips, bellows and EGR pipes.

Begining with two facilities in Rayong in 2003, a third facility in Ayutthaya began operations at the end of April 2005. It caters to all current and future products for Honda, in view of the proximity of the Ayutthaya plant to Honda manufacturing facilities. The facility will also cater to future customers around the area.

The Company's focus on quality, cost competitiveness and on-time delivery are the driving factors of its successful venture and lays the foundation of a continued commitment in growing its business in this market.
