Incision shaping is a treatment method that needs high precision control, which involves adjusting the length, depth and angle of incision to achieve the expected appearance change effect. In order to ensure the accuracy and safety of surgery, the length and size control requirements of incision plastic products are very strict. With the development of modern medical technology, precise size control of incision plastic products can be realized. By using advanced manufacturing technology and sophisticated equipment, manufacturers can control the size of products within the range of 0.5 mm. This high size control can ensure the accuracy and consistency of surgical incision, thus improving the success rate and effect of surgery.
