in 1887 the company was renamed artillerie inrichtingen (a.i.). from this point, all production was no longer centered in delft because the hague grove geschut gieterij was also included in the company. as the company's existing facilities had no space left to expand, a new site was sought. however, this search was limited to the territory within the defenses of the stelling van amsterdam. the company chose a new base of operations near zaandam, where there were already some naval pilots[translation from dutch article needed].
