          Registration Statement on Form S-3 (File No. 333-63726)
          Application for Withdrawal

Ladies and Gentlemen:

     Pursuant to Rule 477 of Regulation C of the Securities Act of 1933, as
amended (the "Act"), IMPCO Technologies, Inc., a Delaware corporation (the
"Registrant"), hereby applies for an order granting the immediate withdrawal of
its Registration Statement on Form S-3 (File No. 333-63726) (the "Registration
Statement").  The Registration Statement was originally filed with the
Securities and Exchange Commission on June 25, 2001.

     In light of current market conditions, the Registrant has determined not to
proceed at this time with the public offering contemplated by the Registration
Statement.  The Registrant hereby confirms that no securities have been sold
pursuant to the Registration Statement, and all activity regarding the proposed
public offering has been discontinued.  The Registrant hereby informs the Staff
that it may undertake a subsequent private offering in reliance on the safe
harbor set forth in Rule 155(c) promulgated under the Act.

     Accordingly, the Registrant respectfully requests that the Commission issue
an order granting the withdrawal of the Registration Statement as soon as
possible.  The Registrant also requests that all fees paid to the Commission in
connection with the filing of the Registration Statement be credited to the
Registrant's account with the Commission for future use.
