Avon Automotive News

Management Led Buyout.

On August 21st Avon Automotive closed its management-led buyout with Avon Rubber p.l.c., acquiring the firm's automotive division with a renewed commitment to outstanding product quality and customer service.

Avon Automotive becomes one of the industry's leading global suppliers of low-pressure hoses for air-induction, fuel and coolant systems as well as vibration-management products.

The business generates net annual revenue of approximately $349 million. It primarily serves the automotive, heavy truck, small engine and recreational vehicle industries.

Red Diamond Capital is the partner for this transaction. Formed in 2002, Red Diamond Capital is an independent $150 million private equity fund that invests in middle market manufacturing, distribution and service businesses in North America. Through their partnership with Mitsubishi Corporation, one of Japan’s leading businesses, Red Diamond offers a unique mix of strategic resources, industry-focused capital, and management expertise that will help fuel the growth of Avon Automotive.

Powertrain Mounts

Rubber / Metal Mount - used to provide a lower cost mounting

Applications:• engine / gearbox / differential mounts

Passive Hydraulic Mount - used to provide improved ride comfort while maintaining acoustic isolation

Applications:• engine mounts - transverse and longitudinal installations• gearbox mounts - particularly longitudinal installations

Semi-active Hydraulic Mounts - used to provide all the benefits of passive hydraulic mount together with improved idle isolation

Applications:• engine and gearbox mounts- particularly longitudinally installed diesel and direct injection petrol engines.

Dual Isolation Mounts -used to provide improved isolation at higher frequencies

Applications:• can be combined with any of the above mounts - particularly used where secondary isolation of a subframe / cradle is not available

Active engine mount - Vibramount®

Applications:• Combines classic hydraulic performance with patented closed loop active control. The first fully closed loop active mount in production.
