Good Morning. I am located in Guatemala, Central America. I work making natural latex balloons. I need near to 20,000 moulds of special measures now to make latex balloons. I usually use ceramic and polypropylene mould. Now I need SS moulds. The stem starts with 14 mm diameter and 70 mm length. Then it has a decrease until it ends in a flat part. This ends in a thickness of 1.5 mm and length of 20 mm. I can send a sample of the mold that I need. Best regards. Jose Luis.
