Ballpoint pens are commonly used in life, but did you know that the nib is actually a tiny tungsten carbide ball? It seems small, but it is very difficult to actually manufacture, and it cannot be made without any strength. zhuzhou Jinxin has advanced technology and equipment, and can customize the specifications of tungsten alloy balls. The products have good quality, long service life and high cost performance.
When writing, it mainly uses the tungsten alloy ball of the pen tip to directly contact the paper surface to generate friction, so that the ball rolls in the ball seat, and uses gravity to bring out the ink or ink in the pen core, so that the ballpoint pen ink or ink It seeps into the tip of the pen, and forms text or graphics by rolling the balls of the pen tip. The subsequent ink or ink is constantly replenished under the action of atmospheric pressure to achieve the purpose of writing. Most of the early ballpoint refills had a small hole drilled near the tail to allow air to circulate. The diameter of the ballpoint pen ball determines the thickness of the writing line. Common ball diameters are 1 mm, 0.7 mm, and 0.5 mm (it is often indicated on the pen body or ballpoint refill of the product).
The nib and ink are the keys to a ballpoint pen, where the nib is divided into a ball on the nib and a ball seat body. At present, tungsten alloy balls are the most widely used at home and abroad. my country already has a very good foundation, which can not only meet the needs of domestic production, but also provide a large number of exports.
