Introduction of vacuum metallizing machines to process plastic film in 3m
Metallizing was generally done by batch system available for the width of 2m conventionally. By orignal idea and technology, however, Saichi realized continuation metallizing technology for 3m wide film by three chamber methods.
The consecutive metallizing technology by the three chamber methods cleared the problem that the industry of metallizing had and which could not be overcome. As a result, the production efficiency was improved greatly.
