Moreover, since the establishment of a long time ago,the springsbusiness of AFR Precision has always maintained a high-speed and stable growth. details: Needle tubing spring pen point and ball-point pen cartridge comprising sameThe invention provides a needle tubing spring pen point. The needle tubing spring pen point comprises a cylindrical ball seat body, a ball and a spring, wherein one end of the ball seat body is provided with a ball seat; the other end of the ball seat body is provided with an opening and a lock part adjacent to the opening; the ball seat body also comprises an ink supply passage formed between the ball seat and the opening; the ball seat is provided with a central hole and a plurality of oil slots; the ball is arranged in the ball seat and is protruded from the ball seat; the spring is positioned in the ink supply passage and is made of stainless steel wires with the diameter of 0.08-0.1mm; the external diameter of the spring is 0.5-0.55mm; and the edge of the ball seat is bent and deformed towards the ball to receive balls, so that a radial gap and an axial gap are formed between the edge and the balls. The invention also provides a ball-point pen cartridge comprising the needle tubing spring pen point. By the needle tubing spring pen point, the whole spring can be placed in the pen point under the condition that the pen point is thinner and the inside space is smaller, and can be matched with ink with middle viscosity and thixotropy to achieve a better effect.Thus, it invented spring tip, i.e., mounting a small spring-loaded ball inside the tip, the equivalent of one-way valve means of a spring force to the ball and the ball seat between the side port when not writing the gap is closed, to prevent it from drying, the purpose of the incoming air; rely writing pressure greater than the spring force of the writing ball and the ball seat opens a gap between the lip, ink flows properly writtenCurrently, the market spring tip shape having a diameter of mainly 2. 3mm, a length of 11. 5mm bullet shape, the internal diameter stainless steel wire spring mounting O. 12mm, the diameter of the ball O. 5mmvery small space inside the tip, the tip springs also increases and a new function of the spring, both in the internal structure of the dimensioning or machining accuracy, and in matching the tip of the ink requirements are higher, more difficult, It can be said is the largest of all written in technical difficulty.

3.The integrity, strength and prodzationuct quality of AFR Precision Technology Co.,Ltdhas gain highly industry recognition. Welcome friends from all walks of life come for visit, guidance and business negotiations. For more information please visit:
