We select high-quality inks with appropriate viscosity to ensure that they can flow evenly and stably in the rollerball pens. This ink not only has good writing performance, but also maintains consistent writing effects on different papers to avoid blurred or broken handwriting. The ink formula has been carefully formulated to ensure that it has good drying properties and can quickly adhere to the paper when writing, reducing the penetration and diffusion of the ink, thereby ensuring the clarity and durability of the handwriting.
The ball is the core component of the rollerball pen. We use a ball made of cemented carbide (such as tungsten carbide). This material has high strength and high wear resistance. It can maintain stable rolling during writing and ensure uniform output of ink. The design of the nib fully considers the comfort and smoothness of writing. By optimizing the channel structure inside the nib and the fixing method of the ball, the resistance of the ink during the flow process is reduced and the smoothness of writing is improved.
We use advanced production processes and equipment to strictly control every production link of the rollerball pen to ensure that the accuracy and quality of each component meet the design requirements. Especially in the process of installing the ball and filling the ink, we use precise equipment and strict process flow to ensure the close fit between the ball and the pen tip and the uniform distribution of the ink. During the production process, we also set up multiple quality inspection procedures to conduct comprehensive inspections on the writing fluency of the ball pen, the drying speed of the ink, the clarity of the handwriting, etc., to ensure that each ball pen meets the quality standards.
It is recommended that students use the correct pen holding posture to avoid excessive or insufficient force to reduce the impact on the writing fluency of the ball pen. Try to avoid using the ball pen in extreme temperature or humidity environments to prevent the ink from solidifying or diffusing and affecting the writing effect. Clean the ball pen regularly to avoid dust, grease and other impurities clogging the pen tip or affecting the rolling of the ball, and maintain the smoothness of writing.
We ensure the writing fluency of students using the national style design series ball pen through many measures such as the selection of high-quality ink, precise ball and pen tip design, scientific production process and user suggestions.
