Preforms for Precision Moulding

Preforms for precision moulding are glasses exclusively developed for use in precision moulding processes. They are widely known as low melting point glasses. The hot process preform, which is formed into the final shape directly from the melting furnace, is distinguished by the prefix “MP-xxxx”. While the cold process preforms, which are formed into a both-side polished lens through conventional polishing processes, are distinguished by the prefix “MC-xxxx”.

Our strong point

Preforms for precision mouldings have a low melting point compared with the conventional optical glass. Low melting point glass enables a cost effective molding process because of the improvement of process cycle time and the increased life time of the mould die. All of our preforms are environmentally friendly, containing no lead or arsenic.
