                AMCAST REPORTS FISCAL 2004 SECOND QUARTER RESULTS


DAYTON, OHIO, March 23, 2004 - Amcast Industrial Corporation, (AICO.OB) today
reported financial results for its fiscal 2004 second quarter ended February 29,
2004.

Sales of $94.4 million in the second quarter were 4.7% lower than the prior year
quarter sales of $99.1 million. Operating income in the second quarter of $2.4
million was up by almost 31% over the prior-year quarter. The operating income
improvement was the result of an improved gross margin due to reduced
manufacturing costs and lower selling, general and administrative costs. The
profit improvement at the operating level was much more dramatic than the
after-tax level because tax benefits were significantly higher in the prior
year. The net loss of $1.2 million, or $0.13 per share, improved by 6.7% over
the net loss from continuing operations in last year's quarter of $1.3 million,
or $0.15 per share.

The quarterly sales decline resulted from lower aluminum components sales,
primarily in the gravity-cast operations. This decline was partly offset by
strong demand for plumbing products and pistons for automotive air conditioning
compressors. By segment, Flow Control sales grew by over 18%, but Engineered
Components sales fell by almost 15%.

During the second quarter last year, the Company recorded a loss on the sale of
Speedline, its European wheel business. Accordingly, Speedline was classified as
a discontinued operation. The after-tax loss in fiscal 2003 from discontinued
operations was $54.6 million, or $6.17 per share, for the second quarter and
$56.7 million, or $6.82 per share, for the first six months.

Year-to-date sales were $207.4 million, down by 1.9% versus the prior year.
Sales in the Flow Control segment were up by 14%, while Engineered Components
sales declined by 8%. Year-to-date operating income of $7.3 million grew from
$2.7 million last year, or by 165%. Both an improved gross margin and lower
selling, general and administrative expenses contributed to the increase. Year
to date, the Company's net loss from continuing operations was $0.2 million, or
$0.02 per share, compared with a net loss from continuing operations of $3.2
million, or $0.36 per share, in the prior year.

Joseph R. Grewe, President and Chief Executive Officer, said, "The operating
income increase reflects better manufacturing performance, and it is important
to recognize that operating income increased during a period of declining sales.
We are still, however, turning the corner to profitability at the net income
line. Management has continued to focus on lower spending. During the quarter
selling, general and administrative expenses decreased by almost 7%, and fell to
9.1% of sales from 9.3% of sales in the prior-year quarter. Year-to-date
selling, general and administrative expenses were 8.1% of sales. Productivity
increased over last year by almost 14% year to date as measured by sales per
full-time-equivalent employee. Continued implementation of lean manufacturing
concepts as well as internal quality improvements helped improve performance."

Byron Pond, Chairman, commented, "Amcast's balance sheet continued to improve in
the quarter. Net operating assets decreased by 1% during the quarter as capital
spending was held to 34% of depreciation. Amcast also reduced debt by $3 million
in the quarter, and debt has been lowered by over $5 million year to date."

Mr. Grewe concluded, "Amcast just missed net income break-even for the first six
months. However, this was the Company's ninth consecutive quarter of positive
operating income. Traditionally, the second quarter is our most difficult
quarter, and this year was no exception. Clearly, the Amcast Production System,
and our relentless efforts to reduce costs are producing operating and financial
benefits. Our plans are to continue these successful programs as well as focus
on process improvements, better quality, and improved customer service."
