A pen writing performance is good or bad, writing fluency and writing durability are subject to testing. Usually when we write, we will not worry about the problem of ink seepage, will not worry about the writing is not smooth, in fact, the appearance of these problems are indicative of the quality of the product is not up to scratch.

Our company's self-developed, self-produced and self-marketed writing machine has been updated to the third generation——Pen-Core Circle Writing Tester

The machine simulates the state of writing with a pen, puts the sample on a certain load, and writes a circle mark at a certain speed to check whether the structure and performance of the sample are intact.

High accuracy, simple operation, easy observation, high automation level, favored by major manufacturers, not only can draw Z, but also can draw circles.
