Topfine
1993
In 1993, a "Complete Close-Loop Servo Control System" was successfully
developed and applied to Topfine machines.
This was an integrated system consisting of a precision mould
cavity pressure sensor, a high-response servo value, linear displacement transducers and
EL-Graphical display multi-function computer.
The introduction of these features has pushed Hong Kong plastic
machinery technology to superior level.
