Because the tours are given by active members of staff, and in order to have the minimum impact on daily working life, visits are only possible on Fridays between 10 a.m. and 11.30 a.m. We do offer larger groups the option of visiting the Open Factory on a different day of the week. You can express the desire to do so in the field for other questions or comments when you book. A member of staff at Mountech Co. Ltd. will then contact you.
