Application of needle laser cutting machine in insulin injection needle

(Click 9 )

Insulin injection needle is an important tool for daily treatment of diabetic patients, and its manufacturing is inseparable from needle laser cutting machine. This equipment uses high-energy laser beams, like a “microscopic engraving knife”, to complete precision processing on extremely thin metal needle tubes, providing technical guarantee 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 is composed of fiber lasers, multi-axis linkage motion systems and intelligent CNC platforms, 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: Carve tiny holes on the side of the needle tube that are difficult to see with the naked eye to ensure that the liquid medicine flows out evenly.
Surface polishing: Use the thermal effect of the laser 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, design a shorter needle tube for children, or adjust the side hole layout 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.
