Abstract
The invention discloses a manufacturing process of the parts related to the elbow and wrist joint of an artificial upper limb. The manufacturing method is that a novel composite material with mixed nylon and long glass fiber is used to perform the injection molding process instead of the traditional metal cutting machining process. The related parameters of the selected material and the related technological parameters are as follows: 1. the composite material with mixed nylon and long glass fiber comprises the following components by weight percent: 30%-50% of nylon (PA), 50%-65% of glass fiber, 2-3% of coupling agent, 1-2% of plasticizer and 1% of other components; 2. the injection process of the composite material is that the temperature of the material tube is 280-310 DEG C, the injection pressure is 40Mpa, the injection time is 15-35 seconds and the shaped parts are completely cooled at the room temperature; and 3. the parts are dried at 130 DEG C for 4-6 hours before shaped. An injection machine with the tonnage of 100-500 is used to inject the fused liquid raw material in the injection moulds through an injection machine, and the novel composite material is adopted to prepare the parts related to the elbow and wrist joint of the artificial upper limb through the process technology of injection molding.
Description
technical field [0001] The invention relates to a manufacturing method of a prosthesis, in particular to a manufacturing method for upper limb elbow joints and wrist joints, using new composite materials through an injection molding process. Background technique [0002] At present, the production process of the relevant parts of the upper limb prosthetic joint is metal cutting machine forming. The processes used involve wire cutting, turning, milling machine processing, grinding machine processing, and CNC machine tool processing. There are many production processes, heavy workload, and long labor hours. , To form large-scale production, the required equipment, personnel, and time investment are relatively large, the production cost is high, and the production efficiency is low. [0003] The injection molding process of the new composite material is to bake the new composite material of nylon mixed with long glass fiber to the temperature and humidity suitable for injection...
