Mould equipment utilized for borosilicate glass production is; Moulds, Rings, Ring Holders,
Plungers, Plunger Cooler Boxes, Plunger Holders.
During borosilicate glass production, moulds are exposed to higher pressing pressures and
heating temperatures than soda lime glass products. Therefore, Merkad uses1.2787 stainless steel material with 32-34 Hrc hardness for its borosilicate moulds. For plungers, special powder weldings are utilized to give extra hardness on Plunger surfaces with 45 Hrc. Special cooling profile on Plungers will also help to have long-lasting Plungers and high quality glass products.
