The aspherical lenses used desital cameras etc. are made by pressing preforn
lenses produced molded lenses.
Non-Contact Transfer Device for Prefom Lenses and molded lenes is used under mentioned process.
1. Transfering preform lenses from the career to the press.
2. Positioning the preform lenses into the metal stamping process
3. Press the preform lenses in the press metalic mold.then removing
from the molded molded lens
For inserting and removing
To & from metallic Mold
For inserting and removing
To & from metallic Mold
Prefom lenes are non-contact inserted and removed are Press Machine.
The above process will be performed without touching the prefom lenses.
In The Vertical Gas Flow System(VGFS),By making a cushion room carry out the vertical gas jet flow of the gas
style spouted from the nozzle, the gas vertical jet gas flow decreases
friction loss of the gas flow of the cushion room.
Moreover the Non-contact transfer equipment"Float Chuck Type SA-C (SAN)" has three new technologies which are Bernoulli effect,Ejector effect and Coanda effect.
They increase the effect of negative pressure generating, and making holding
capability increase conventionally more sharply than type, and its maintenance
stability former power was strong against increase and the shock, and it
reduced the amount of gas consumption by half mostly.
◎ characteristics
1. Non-contact conveying preform lenses and molded lenses.
2. Preforms can be non-contactedly inserted into the metalic mold.
3. After press forming, non-contactedly removed from metallic press.
