Carburetor, Piston, Piston Ring, and Valve Manufacturing

INDUSTRY SNAPSHOT

Carburetors, pistons, intake and exhaust valves, and piston rings account for a relatively small and declining portion of the broader automotive and machine engine parts manufacturing industries, which was valued at more than $28.2 billion in 2002. After declining significantly during the early 1990s, shipment values began to grow in the late 1990s, increasing from $2.7 billion in 1997 to $3.3 billion in 2000. Shipment values then declined sharply to $2.1 billion and $2.0 billion in 2001 and 2002, respectively. Industry employment also fell off sharply in the early 2000s, reaching a 5-year low of 11,982 in 2002, down nearly one-third from 17,706 in 1998. The auto parts sector is a challenging industry due to stiff competition and price pressures. Although piston and valve sales were holding steady during the mid-2000s, carburetor sales continued a gradual, steady decline.

ORGANIZATION AND STRUCTURE

This industry supplies engine parts as original equipment and as aftermarket replacement parts. Although 75 percent of the industry's companies employed less than 100 workers in mid-2000s, the small portion of large companies that employed more than 100 workers accounted for approximately 80 percent of product shipment values. In 2002 the industry claimed 132 establishments, predominantly in California, Nevada, Michigan, Ohio, and Texas.

The total auto parts industry is very fragmented and consists of thousands of suppliers, ranging from small specialty shops to multinational corporations. In general, this industry sector is comprised of four lines of business: original equipment, replacement parts, distribution, and rubber fabrication. Original equipment is manufactured and sold to the automobile companies...
