Injection molding process for metal handles of medical forceps

Abstract

The invention discloses an injection molding process for metal handles of medical forceps. The injection molding process specifically comprises the following steps of (1) product designing; (2) mold manufacturing; (3) material mixing; (4) feeding; (5) injection molding; (6) debonding; (7) sintering; (8) re-machining; and (9) inspecting. The invention relates to the technical field of medical instrument machining, in particular to an injection molding process for metal handles of medical forceps. Compared with a traditional injection molding process for metal handles of medical forceps, the injection molding process for the metal handles of the medical forceps has the following advantages that 1, parts with complex geometrical shapes are directly formed; 2, the product is high in size precision and smooth in surface; 3, the product is good in internal compactness and high in density; 4, the internal structure is uniform, and no component segregation phenomenon exists for the alloy; 5, the production efficiency is high, and the production cost is greatly reduced under the condition of mass production; and 6, the application range of the materials is wide, and the materials comprise materials which are difficult to melt, cast and machine.

Description

technical field [0001] The invention relates to the technical field of medical device processing, in particular to an injection molding process for metal handles of medical forceps. Background technique [0002] As a commonly used medical device in the medical process, medical forceps are mainly used to hold gauze, cotton wool and other items, and are also used to remove the patient's inner cavity tissue or foreign objects in the body. At present, the metal handles of medical forceps on the market are mainly manufactured by the following two preparation processes, one is precision casting and precision forging process; the other is machining process. The production of metal handles made by precision casting and forging technology is difficult, and it is not easy to achieve mass production. Therefore, the product price of medical forceps is relatively high; the mold processing of metal handles made by precision forging and forging technology is difficult and requires high mat...

AI Technical Summary

Problems solved by technology

The production of metal handles made by precision casting and forging technology is difficult, and it is not easy to achieve mass production. Therefore, the product price of medical forceps is relatively high; the mold processing of metal handles made by precision forging and forging technology is difficult and requires high material requirements. At the same time, The degree of freedom of shape is poor; while the material degree of freedom and mass production of machining technology are limited by the processing technology, and the product price is relatively high
