Application of Metal Injection Molded Parts in Medical and Dental Fields

At present, the proportion of MIM injection molding process in the market is the largest in the communication electronics application, followed by the medical industry. In the dental market, MIM parts are very competitive with small components and complex mim process flow.

(1) MIM parts: laparoscopic surgical scissors

This is completed by metal injection molding process, made of 17-4PH stainless steel powder, with cautery capability of abdominal surgery scissors. A pair of straight inserts are made by one injection molding, and the inserts are trimmed to make matching inserts with calibrated preload, relief angle and curvature. The blade needs to be heat treated and aged, and the cost of MIM helical gears can be reduced by 80% compared with the helical gears manufactured by customers who edge and cut the blades.

(2) MIM parts: endoscope scissors

Surgical instrument scissors are disposable devices composed of blades, hooks and brakes, used for endoscopic surgical scissors. The wool cutting scissors can be used for cutting, cauterizing, coagulation during minimally invasive cardiac surgery, general surgery and plastic surgery. The customer needs to shape it to the required curvature with a toggle press. Brakes and rings require a one-time finish to adjust the width of the bracket. The paired bending and sharpening of the blades are performed by the customer.

(3) MIM parts: sewing jaws

This surgical instrument is a lower jaw used for medical suturing devices, and is a complex-shaped part made of 17-4PH stainless steel. The lower jaw is a key part in the suture device, which can be fastened and sutured with one hand, and the stitches of the sutured lip are uniform.

(4) MIM Parts: laparoscopic gripper

This surgical instrument part is a jaw part made of 17-4PH stainless steel powder by mim machining process. It consists of upper and lower jaws, a fixator and an I-beam. This highly compressible jaw is used for laparoscopic containers. melt. The as-sintered density of the MIM parts was 7.6 g/cm. These parts have thin walls and complex geometries that are difficult to produce economically using any other process. Mounting the upper and lower jaws on the pivots of the raised portion allows the assembly to rotate; the cutting mechanism of the laparoscopic device lies in the shape of the I-beam; as the blade advances from the proximal side to the far side of the jaws, it is High compressibility. The system incorporates inventive electrotechnical techniques in a high-compression jaw design that allows the vessel to melt quickly without thermal effects.

(5) MIM parts: dental restorative brackets

This part is used to supply air, water, and a manual fiber optic rotation device that simultaneously illuminates the oral cavity with fiber optic light. This is a MIM part craft made from 17-4PH stainless steel powder. Due to the small diameter of the drill bit, it is not possible to drill holes with the drill bit after sintering. Therefore, this part was drilled in the raw and broken state of NIM forming. Previously, this part was produced by cutting, and the yield was only 60%. Now it is produced by MIM process.

(6) MIM parts: orthodontic parts

These parts are a series of buccal ties for orthodontic brackets, this series is composed of a number of 17-4PH stainless steel parts prepared by the MIM process. In all-metal self-ligating orthodontic appliances, this is the first time this series of buccal ties has been used.
