                    PROXY STATEMENT FOR 1998 ANNUAL MEETING
 
                              GENERAL INFORMATION
 
     This proxy statement is furnished to shareholders of Amcast Industrial
Corporation, an Ohio corporation (hereinafter the "Company"), in connection with
the solicitation by its Board of Directors of proxies to be used at the Annual
Meeting of Shareholders to be held on December 17, 1998, and any adjournment
thereof. The Company has one class of shares outstanding, namely Common Shares,
of which there were 9,206,529 outstanding at the close of business on October
22, 1998. The close of business on October 22, 1998 has been fixed as the record
date for the determination of shareholders entitled to notice of and to vote at
the Annual Meeting, and each such shareholder is entitled to one vote per share.
 
     All Common Shares represented by properly executed proxies received by the
Board of Directors pursuant to this solicitation will be voted in accordance
with the shareholder's directions specified on the proxy. If no directions have
been specified by marking the appropriate squares on the accompanying proxy
card, the shares will be voted in accordance with the Board of Directors'
recommendations. A shareholder signing and returning the accompanying proxy has
the power to revoke it at any time prior to its exercise by voting in person at
the meeting, by delivering to the Company a later dated proxy, or by giving
notice to the Secretary of the Company in writing or in open meeting but without
affecting any vote previously taken.
 
     The presence, in person or by properly executed proxy, of the holders of a
majority of the Company's outstanding shares is necessary to constitute a quorum
at the Annual Meeting. Shares represented by proxies received by the Company
will be counted as present at the Annual Meeting for the purpose of determining
the existence of a quorum, regardless of how or whether such shares are voted on
a specific proposal. Abstentions will be treated as votes cast on a particular
matter as well as shares present at the Annual Meeting. Where nominee
shareholders do not vote on specific issues because they did not receive
specific instructions on such issues from the beneficial owners of such shares
("Broker Nonvotes"), such Broker Nonvotes will not be treated as either votes
cast or shares present.
 
     This proxy statement and the accompanying form of proxy were first mailed
to shareholders on or about November 10, 1998.

                             ELECTION OF DIRECTORS
 
     The Company's Board of Directors is divided into three classes. Each class
is comprised of three directors, and one class is elected at each Annual Meeting
of Shareholders for a term of three years.
 
     At the 1998 Annual Meeting, shareholders will elect three directors who
will hold office until the Annual Meeting of Shareholders in 2001. The Board has
nominated Walter E. Blankley, William G. Roth, and John H. Shuey for election as
directors at the 1998 Annual Meeting.
 
     It is the intention of the proxy agents named in the accompanying proxy to
vote such proxy for election of Messrs. Blankley, Roth, and Shuey. Should any of
them be unable to accept the office of director, an eventuality that is not
anticipated, proxies may be voted with discretionary authority for a substitute
nominee or nominees designated by the Board of Directors. Messrs. Blankley,
Roth, and Shuey are presently directors and are nominated to succeed themselves.

Certain Information Concerning the Board of Directors
 
     There were six meetings of the Board of Directors during fiscal 1998. The
Board of Directors has four standing committees (the number of meetings of each
committee in fiscal 1998 is shown in parentheses): Executive Committee (0),
Audit Committee (2), Compensation Committee (4), and Pension Review Committee
(1).
 
     The Executive Committee (Messrs. Shuey (Chairman), Baker, Forster, and
Ladehoff) is authorized, in intervals between meetings of the Board of
Directors, to exercise all the powers of the board with the exception of filling
vacancies on the board or any board committee. The Committee also reviews and
makes recommendations to the board concerning the performance, development, and
succession of executive personnel, and the composition, organization, and
operation of the Board of Directors. The nonemployee directors of the Executive
Committee act as a nominating committee for directors and will consider
candidates recommended for nomination by shareholders. If a shareholder desires
to recommend to this Committee a person to consider for nomination, the
shareholder should give written notice to the Secretary of the Company, at the
Company's principal executive office, Washington Park I, 7887 Washington Village
Drive, Dayton, Ohio, 45459, at least 120 days before the date of the meeting of
shareholders at which directors are to be elected. Such notice should state the
name, age, business, and residence address of the proposed candidate, and the
principal occupation or employment of the proposed candidate.
 
     The Audit Committee (Messrs. Gorr (Chairman), Ladehoff, and O'Loughlin)
meets with Company personnel and with representatives of Ernst & Young LLP, the
Company's independent auditors, to consider and review internal accounting
controls and matters relating to the annual audit of the Company's financial
statements. The Committee also monitors compliance with the Company's conflicts
of interests and business ethics policy and annually recommends to the board the
appointment of independent auditors.
 
                                        3
   6
 
     The Compensation Committee (Messrs. Roth (Chairman), Baker, and Van Sant)
reviews the Company's compensation plans for officers and key employees and acts
in an advisory capacity to the Board of Directors in all matters relating to
compensation of officers.
 
     The Pension Review Committee (Messrs. Forster (Chairman), Blankley, and
O'Loughlin) reviews the administration of retirement plans, investment manager
and trustee performance, and the results of independent audits of plan financial
statements.
 
     During fiscal 1998, each director attended 75 percent or more of the total
number of meetings of the Board of Directors and the Committees on which he
served.
 
     Each nonemployee director receives a yearly fee of $16,000, which is
payable in cash or Company shares at the option of the director, and a grant of
200 restricted shares for services as a director and $1,000 for each meeting of
the Board of Directors that he attends. A fee of $1,000 is paid for each
committee meeting attended. A director may elect to defer receipt of fees
payable to him into a cash account upon which the Company pays interest or, at
the director's option, into Company shares. Payment of deferred amounts
commences after the director ceases to be a director or on an earlier date as
specified by him.
 
     The Company's 1989 Director Stock Incentive Plan, approved by shareholders
in December 1988, provides that options to purchase up to a maximum of 120,000
shares may be granted to directors who are not employed by the Company. Under
the plan, each nonemployee director, who is a director of the Company on the
first business day of January of each year, is automatically granted an option
to purchase 1,500 shares at an option price per share equal to the fair market
value of a share on the date of grant. Options become exercisable one year after
grant.
 
     The Company believes that it is important for directors to have a
meaningful ownership position in the Company. Stock ownership guidelines are
therefore established for directors. Directors are expected to achieve ownership
levels of Company stock equal in value to three times their yearly fee and
restricted stock grant.
 
            SECTION 16(a) BENEFICIAL OWNERSHIP REPORTING COMPLIANCE
 
     Section 16(a) of the Securities Exchange Act of 1934 requires directors and
executive officers of the Company and owners of more than 10 percent of the
Company's common shares to file an initial ownership report with the Securities
and Exchange Commission and a monthly or annual report listing any subsequent
changes in their ownership of common shares. The Company believes, based on
information provided to the Company by the persons required to file such
reports, that all filing requirements applicable to such persons during the
period from September 1, 1997 through August 31, 1998 have been met except that
one transaction by Mr. Walker and one transaction by Robert Collevechio, Vice
President, Human Resources, were inadvertently filed after the due date.

                      REPORT OF THE COMPENSATION COMMITTEE
                           ON EXECUTIVE COMPENSATION
 
     PHILOSOPHY. The Company's executive compensation program is based on two
objectives: provide market-competitive compensation opportunities and create a
strong link among the interests of the shareholders, the Company's financial
performance, and the total compensation of the Company's executive officers.
 
     The Compensation Committee of the Board of Directors (the "Committee")
consists of three directors, none of whom is a past or present employee of the
Company. The Committee meets periodically and reviews executive compensation and
makes recommendations to the Board.
 
     There are three components to the Company's executive compensation program:
annual salary, annual incentive compensation, and long-term incentive
compensation. Base salary and all forms of incentive compensation opportunities
are set by periodic comparison to external rates of pay for comparable positions
within the industry.
 
     SALARIES. Base salaries are targeted at the midpoint of competitive data as
measured by Towers, Perrin, Forster & Crosby and other similar services.
Individual variability is based on performance with regard to business acumen,
management competencies and personal competencies, determined by individual
achievement in a number of areas, including, earnings adequacy, business
planning, asset management, leadership, staffing and development, customer
satisfaction and quality commitment. Adjustments are considered periodically,
based upon general movement in external salary levels, individual performance
and potential, and changes in the position's duties and responsibilities. Mr.
Shuey has been Chief Executive Officer since March of 1995. His fiscal 1998
compensation is within the competitive range for chief executive officers in
similar circumstances. For other Named Executive Officers, the Company paid at
or near the competitive data midpoint during fiscal 1998.
 
     ANNUAL INCENTIVES. Annual incentives for Named Executive Officers (other
than Mr. Shuey) are targeted at industrial comparative norms, but paid on the
basis of pre-set percentages of Return on Equity (ROE) for the Company
established by the Board, as applied to corporate officers, and Return on Net
Assets (RONA) of the business units involved, as applied to officers of
divisions or subsidiaries also established by the Board. Performance by the
Company or a specific division or subsidiary at below pre-set levels results in
the elimination of annual incentive awards for the responsible officers. Mr.
Shuey's 1998 annual incentive payment of $200,000 was specified by the Board
based on the Board's evaluation of the Company's performance in fiscal 1998 and
a review of Mr. Shuey's performance by the Board. The Board considered a number
of factors including progress in implementation of the corporate strategy and
the Company's income and performance of the Common Share price during the fiscal
year.
 
     LONG-TERM INCENTIVES. Long-term incentives are provided under the Long-Term
Incentive Plan ("LTIP"). The LTIP provides for grants of two types of awards,
stock options and cash.
 
     Stock option grants are awarded to the Named Executive Officers, including
Mr. Shuey, under the LTIP and other provisions of the 1989 Stock Incentive Plan.
The grant of stock options to senior executives provides additional compensation
and more strongly aligns their interest with those of the shareholders. Stock
option grants are of a number of shares which could be purchased at market value
on the day of the grant for a sum equal to the percentage of the Named Executive
Officer's salary as designated under the
 
                                        6
   9
 
LTIP. Neither Mr. Shuey, nor any of the Named Executive Officers, will realize a
benefit from the options unless and until the market price of the Company's
common shares increases.
 
     Target cash awards, which must be used to purchase common shares, are
awarded to Named Executive Officers, including Mr. Shuey, based on a percentage
of each participant's salary as determined by the Board at the time of the
grant. Payouts, if they occur, are based on the achievement by the Company of
specified goals for ROE averaged over a three-year period established by the
Board at the time of the grant. Participants first become eligible for payments
three years after the date of grant. In fiscal 1998, the grants issued in fiscal
1995 matured. The Company's average annual ROE, as adjusted, during the period
was 12.65%, cash award payments under the fiscal 1995 grants were 52.5% of the
original grant.
 
     STOCK OWNERSHIP GUIDELINES. The Company believes that it is important for
executive officers to acquire a meaningful ownership position in the Company. In
this way, they will bear the same type of risks as are typically incurred by
shareholders, and their interests will be more closely aligned with those of
shareholders. Significant stock ownership focuses executives' attention on
managing the Company as equity owners.
 
     Stock ownership guidelines were therefore established for executive
officers in 1995. Executives are expected to reach ownership levels of Company
stock equal in value to between one and four times their base salary. Executives
are expected to show significant annual progress and to reach such level in a
five-year period.
 
     No employee of the Company received remuneration from the Company in excess
of $1,000,000 in the taxable year.
 
     The Committee believes that the above compensation plans compensate
executives appropriately and competitively.
 
                                           Respectfully submitted,
 
                                           COMPENSATION COMMITTEE

CERTAIN EMPLOYMENT ARRANGEMENTS
 
     The Company has entered into severance agreements with Messrs. Shuey,
Walker, Powell, Watts, Meridew, and certain other officers and key managers of
the Company. Under these agreements, each employee is entitled to severance
benefits if his employment with the Company is terminated within two years of a
change of control of the Company (as defined in the agreement) either by the
employee for good reason or by the Company for any reason other than cause,
disability, normal retirement, or death. In the event of a covered termination,
severance benefits include a payment equal to one, one and one-half, or two
times employee's salary and recent incentive award, depending on the employee's
position and length of service with the Company, and in the case of Mr. Shuey,
three times his salary and recent incentive award and an additional payment to
offset any additional taxes which may be payable by him in the event that any of
the payments made to him by the Company (whether or not made pursuant to the
terms of this agreement) as a result of a change of control of the Company may
be deemed to be an "excess parachute payment" under the U.S. Internal Revenue
Code. The agreements also provide for the payment of the cash value of the
outstanding options in cancellation of the options and the continuance of life
and health insurance coverage until the earlier of the employee becoming
eligible for coverage by a subsequent employer or the expiration of three years.
The agreements also protect the Company against the disclosure of confidential
information and, in certain circumstances, require the employee to pay the
Company 20 percent of the compensation received from a subsequent employer.

(1) Awards consist of the designation of target percentages of annual salary to
    be paid at the end of the performance period if the Company achieves certain
    performance objectives. No payout occurs unless the Company achieves certain
    threshold performance objectives. Above the threshold, payouts may be
    greater or less than the target percentage to the extent that the Company's
    performance exceeds or fails to meet the target objectives specified in the
    plan. Payouts under the LTIP are based on the Company achieving designated
    percentages of Return on Equity (ROE).
 
(2) The performance period includes fiscal year 1998, 1999, and 2000. The future
    payouts, if any, are based upon fiscal year 1998 salaries.

RETIREMENT PLANS
 
     The Company has a noncontributory, defined benefit pension plan for
officers and other salaried employees of the Company and its subsidiaries, which
is a qualified plan under applicable provisions of the Internal Revenue Code
(the "Pension Plan"). Retirement benefits under the Pension Plan are calculated
on the basis of the number of credited years of service the employee has with
the Company, as well as the employee's average annual earnings for the three
highest consecutive years during the employee's last ten years of employment.
The maximum annual retirement benefit that may be paid under the Pension Plan to
any participant under the present law is $130,000.
 
     The Company also has a Nonqualified Supplementary Benefit Plan (the
"Supplemental Plan") which provides supplemental retirement benefits for Mr.
Shuey, Mr.Walker, Mr. Powell, Mr. Watts, Mr. Meridew, and other key employees as
they obtain eligibility under the criteria established by the Board for
participation in the Supplemental Plan. The supplemental retirement benefit is
provided under terms and conditions similar to those under the Pension Plan and
is equal to the excess of (a) the benefit that would have been payable to the
employee under the Pension Plan without regard to certain annual retirement
income and benefit limitations imposed by federal law, over (b) the benefit
payable to the employee under the Pension Plan.
 
     Earnings for the purpose of calculating retirement benefits include salary
and bonuses as shown in the Summary Compensation Table. The credited years of
service at October 22, 1998, for executive officers named in the Summary
Compensation Table were as follows: Mr. Shuey -- 7.7; Mr. Walker -- 3.2; Mr.
Powell -- 4.5; Mr. Watts -- 4.2; and Mr. Meridew -- 13.6.
 
     The following table shows the estimated maximum annual retirement benefits
payable at normal retirement (age 65) under the Pension Plan and Supplemental
Plan at selected earnings levels after various years of service. Amounts shown
are straight-life annuity amounts.
