Ink pen! Achieving a slit width of 0.1mm to accommodate inks of various viscosities!
The customer is engaged in the manufacturing and sales of stationery and was producing with a slit width of 0.2mm. However, they were looking for a manufacturer that could create products with a slit width of 0.1mm, allowing various viscosities of ink to be used without drying out, so that ink would come out when needed. For this product, we conducted test production of mold components to ensure the strength of the parts necessary to create a slit width of 0.1mm, and we manufactured a mold capable of producing four pieces in mass production. By ensuring the strength of the mold components, we were able to produce a mold for mass production of four pieces, allowing for stable mass production of products and enabling the use of various viscosities of ink. [Before Proposal] ■ Previously manufactured with a slit width of 0.2mm ■ Was looking for a manufacturer that could create products with a slit width of 0.1mm, allowing various viscosities of ink to be used without drying out ■ The following specifications are required to store ink at the tip of the ink pen: - Ink must not dry out - Must be able to store the required amount of ink - Previously produced with conventional ABS, but now requires production with recyclable PP *For more details, please refer to the PDF document or feel free to contact us.
