A light guide plate is a transparent plate that directs light to liquid crystal cells in LCDs. On the surface of this product are minute patterns that need to be reprinted precisely. Therefore, we use ZEONOR as the material and injection mold with high injection pressure, and mold temperature of 140°C. To control hazardous burrs on products, the clearance between parts at assembly must be adjusted to less than 5 µm. Shapes with curves must also be adjusted with a clearance less than 5 µm. This means highly precise processing techniques are required.

Tooling for Junction Blocks consists of more than 200 small precise parts, with many such minute parts inserted throughout the Block. A very high level fitting tolerance is required, which creates a very high level of accuracy for each part.
