                AMCAST REPORTS FISCAL 2004 THIRD QUARTER RESULTS


DAYTON, OHIO, June 29, 2004 - Amcast Industrial Corporation (AICO.OB) today
reported financial results for its fiscal 2004 third quarter ended May 30, 2004.

Third quarter sales were $111.4 million, slightly below the third quarter of
last year. Higher plumbing product sales were offset by lower revenues from
automotive customers, primarily in gravity-cast aluminum components. By segment
for the quarter, Flow Control sales rose 42%, and Engineered Components sales
declined by 16%.

Operating income of $5.5 million in the third quarter increased by almost 23%
over the prior-year quarter. This profit improvement came from better gross
margins due to increased manufacturing efficiencies and from lower selling,
general and administrative expenses. Third quarter net income of $1.9 million,
or $0.20 per diluted share, was favorable to net income from continuing
operations for the prior-year quarter, which was $0.7 million, or $0.08 per
share. The prior-year quarter included a loss from discontinued operations
relating to the sale of Speedline, the Company's European wheel business.

Year-to-date sales were $318.7 million, down by 1% compared with the prior year.
Flow Control segment sales rose by 23%, while Engineered Component's sales
decreased by 11%. Year-to-date operating income was $12.8 million, about 77%
above last year. This increase of $5.6 million in operating income was due to
$2.6 million in improved gross margin and $3.0 million in reduced selling,
general and administrative costs. Year-to-date, the Company's net income was
$1.7 million, or $0.18 per diluted share, compared with a net loss from
continuing operations of $2.5 million, or a loss of $0.28 per diluted share, in
the prior year. The first nine months of fiscal 2003 included discontinued
operations and the cumulative effect of a change in accounting principle. These
items combined to produce a net loss of $111.5 million, or a loss of $12.58 per
diluted share.

Joseph R. Grewe, President and Chief Executive Officer, said, "The net income
and operating income growth reflects the continuing success of the Company's
cost reduction and manufacturing improvement programs. Gross margins increased
from 12.2% of sales last year to 12.7% in the third quarter and from 11.1% last
year to 12.0% for the first nine months. In addition selling, general and
administrative expenses declined by 5% in the third quarter to 7.8% of sales
this year versus 8.2% last year. Year to date selling, general and
administrative expenses have declined more than 10% to 8.0% of sales, and
year-to-date labor productivity improved by 14%. We were very pleased to be able
to achieve these performance improvements without revenue growth."

Mr. Grewe continued, "We have reduced debt by $5.0 million during this fiscal
year, but we still remain highly leveraged with debt totaling $172.7 million.
Our cash position has improved somewhat during the year, and we remain current
with our suppliers. However, our net worth remains negative at $40.1 million. In
compliance with our loan agreements, and as previously reported, the Company is
required to use its best efforts to either refinance the bank debt and senior
notes or sell substantially all of its assets by September 1, 2004. The Company
is continuing to have very serious confidential negotiations with parties who
have expressed an interest in acquiring one or more of our business units. Since
these discussions are in various stages of completion, the Company cannot
predict if the results of these negotiations will produce acceptable offers.
However, it is our expectation that one or more of these situations will result
in a transaction. It is also not certain at this point what effect any potential
divestiture might have on the financial condition of the Company or our ability
to refinance the remaining debt."

In conclusion Mr. Grewe said, "Amcast returned to positive net income during the
third quarter. This quarter is the tenth consecutive quarter in which we
achieved positive operating income. To help improve our performance, management
is continuing to implement the Amcast Production System. This initiative has had
a positive impact on our working capital management, product quality, and
overall operating cost."
