Propelling Pencils TRIZ Cases
- Ultra-high flow styrene acrylonitrile copolymer compositions
See how controlled molecular weight distribution and SAN-SBC blending achieve ultra-high melt f
- Inductor Core Surface Roughness for Electronic Pen Coil Protection
A smoother winding-start area on the ferrite inductor core lowers coil tension while preserving anchor effect for more reliable electronic pens.
- Resin Pen Body Composition for Sparkle Without Tool Damage
Mica and fine diamond dust in polymer resin create glittering pen rods that machine cleanly while lowering cost and tool wear.
- Replaceable Ink Cartridge With Self-Opening Plunger Barrier
A plunger-driven barrier lets the cartridge open itself for cleaner refilling, avoiding wear-prone opening parts in the writing instrument.
