Glass thickness managed at 0.02mm rank! Stabilization of molding with weight and mold-specific settings.
Variations within specifications cause molding defects. We absorb variations through weight selection in 0.02mm increments and by setting conditions specific to each mold.
In glass insert molding (GIM), even within standard values, variations in the thickness of the glass material can affect compatibility with the mold, leading to uneven molding pressure, glass breakage, and appearance defects. Yoshida Technoworks has established a method for mass production of GIM for Kyocera's JA83, where the thickness of the glass is classified in increments of 0.02mm, and rank management is implemented through weight selection. Furthermore, by associating the glass rank with the molding conditions for each mold number, variations within the same material are absorbed by the molding conditions, ensuring stable mass production quality. This method is particularly effective in improving yield for GIM products that use thin glass (1mm or less).
