Exhibit 99-Press Release of Amistar Corporation dated July 31, 2003, reporting
Amistar's financial results for the second quarter 2003.

              AMISTAR REPORTS SECOND QUARTER 2003 FINANCIAL RESULTS

SAN MARCOS, CALIFORNIA, July 31, 2003 /PR Newswire-First Call/ -- Amistar
Corporation (Nasdaq:-AMTA) today reported sales and results for the quarter and
six months ended June 30, 2003.

Net sales for the quarter ended June 30, 2003 were $2,652,000 compared to
$2,827,000 for the second quarter in 2002. Net sales for the six months ended
June 30, 2003 were $5,421,000 compared to $5,468,000 for the similar period in
2002.

There was a net loss for the quarter ended June 30, 2003 of $79,000 or $0.03 per
share compared to a net loss of $454,000 or $0.15 per share in the second
quarter of 2002. There was a net loss for the six months ended June 30, 2003 of
$225,000 or $0.07 per share compared to a net loss of $556,000 or $0.18 per
share in the comparable period of 2002.

During the quarter ended June 30, 2003, the Company continued its trend of
successive quarterly operating earnings improvement since the second quarter of
2001. After adding back depreciation expense of $88,000 to the net loss of
$79,000, the Company generated a positive operating cash flow of $9,000 in the
second quarter of 2003. The Company narrowed its net loss during the quarter and
six months ended June 30, 2003 compared to the same period in 2002, primarily
due to an increase in DataPlace label placement machine and custom factory
automation equipment sales, the effects of cost cutting in prior quarters, and
due to increased manufacturing efficiencies in the Amistar Manufacturing
Services division.
