Latest Patents
Sakuda's latest patents include a synthetic resin pen nib and a method of manufacturing synthetic resin pen nibs. The synthetic resin pen nib is designed using thermoplastic crystalline synthetic resin, such as polyethylene terephthalate resin. This pen nib is particularly suitable for fine lettering and drawing fine lines. The unique structure of the pen nib consists of molecularly oriented crystals, non-oriented fine crystals, and remaining amorphous regions, which collectively enhance its physical and chemical properties.
The method of manufacturing synthetic resin pen nibs involves extruding the resin from a molding die and rapidly cooling it to form a continuous rod in an amorphous state. This rod is then axially stretched under specific temperature conditions to achieve oriented crystallization. The resulting pen nib exhibits improved physical and chemical properties, making it ideal for precision writing instruments.
