Application of needle laser cutting machine in insulin injection needles
(Click 29 )Insulin injection needles are important tools for daily treatment of diabetic patients, and their manufacturing is inseparable from needle laser cutting machines. This equipment uses high-energy laser beams, like a “microscopic engraving knife”, to complete precision processing on extremely thin metal needle tubes, providing technical support for improving injection safety and comfort.
The needle laser cutting machine is a non-contact precision processing equipment based on high-energy laser beams, designed for cutting ultra-fine metal tubes. Its core consists of a fiber laser, a multi-axis linkage motion system and an intelligent CNC platform, which can realize complex structure processing of 0.1-5mm diameter tubes, and is particularly good at processing medical consumables with extremely high precision requirements such as cardiovascular stents and minimally invasive surgical instruments.
Traditional needle manufacturing relies on mechanical stamping, which is prone to burrs or deformation. The laser cutting machine uses a computer to accurately control the laser energy and process the needle tube in a non-contact manner:
Needle tip shaping: Cut a smooth bevel at the end of a 0.3 mm thin needle tube to form a sharp puncture tip to reduce the pain during acupuncture.
Side hole drilling: tiny holes that are difficult to see with the naked eye are carved on the side of the needle tube to ensure that the liquid medicine flows out evenly.
Surface polishing: the thermal effect of the laser is used to simultaneously polish the incision, making the inner wall of the needle tube as smooth as a mirror to avoid residual liquid medicine.
With the advancement of technology, laser cutting can also realize personalized customization of needles. For example, designing shorter needle tubes for children, or adjusting the layout of side holes for patients with special body shapes. This laser cutting technology is quietly changing the daily lives of millions of diabetic patients, making the treatment process easier and safer.
