Precision molding technology

 Precision Molding Technology

Moving into the realm of the nanometer

As a result of reducing the effects of temperature, humidity and vibration, we have succeeded in further improving the accuracy of Enplas’s precision mold processing technology.


SR mark processed on both sides of an optical slope of 45 ° with 12 free-form surface lens array.

Using special tools, slope angle shaper accuracy, free-form surface array and SR surface (raster) pitch accuracy, nano-level accuracy has been achieved on the lens surface.

Analysis Technique

Analysis Technique

Evolving simulation technology

CAE (Computer Aided Engineering) has become common as a design technology. It is one of the key technologies that support innovation. At Enplas, from its inception we have been leveraging non-liner CAE for product/ mold design and development. Recently, we have started utilizing high performance computing technology (HPC). Together with evolving computer technology we continue to evolve our design and development technology.

Precision measurement technology

Precision Measurement Technology

Excellent evaluation technology

The strength of excellent precision measurement technology as a device manufacturer, accurate assessment of our products (shape, size, function) is required. Fully grasping and guaranteeing product specifications promised to customers (shape, size, function), we are committed to the improvement of our evaluation technology, introducing new evaluation equipment in order to respond to higher precision and diversification of product functionality.
