Key points

  • Assuming production process for optical component from designing to molding to achieve accuracy improvement and error reduction
  • Maximizing the properties of products by addressing in the product design the problems that occur in each process of mold processing
  • Considering the expansion and contraction caused by temperature changes during the ultra-precision electroforming (EF) processing in the post process
  • Also applicable for automotive, bio-medical, optical and next-generation priting partsNot only for semiconductor and electoronical, inaddition to semiconductor and electronic parts

Consistent approach from designing to molding of optical parts requiring high quality and high accuracy

Manufacture of optical parts is divided into several processes such as design, mold making, resin molding. By dividing the process into divisions, we can conduct inspections at each stage and manufacture the ideal shape and performance at design time with high yield in final resin molding.

A Consistent Approach to the Process from the Design to the Molding of Optical Parts, for Which High Quality and High Precision Are Required

We handle the process of manufacturing optical components, from design to resin molding, in a consistent manner. By understanding and practicing all the processes involved in manufacturing optical parts, we can manufacture products maximizing the properties desired by customers.

Use of Towa's Proprietary Optical Simulation System

We simulate the properties of optical parts by using our proprietary optical simulation system.
We also optimize their properties into those required by customers and suggest measures for reducing costs, based on our basic research on design to production, which we have undertaken for many years to manufacture high-performance products, as well as a wealth of material technologies, mold design technologies, and others.
