description The invention discloses a technique for machining a plastic five-star leg of a pneumatic chair. According to the technique, 5% of stabilizer is added to raw materials during machining, and the stabilizer can well stabilize a plastic macromolecular structure under the high temperature condition, so that the situation that the structure of plastic is damaged due to the fact that the temperature is too high is prevented during injection molding; the mixed materials are dried for 30 min, due to the fact that the five-star leg needs to be formed through injection modeling, water in melt can affect the quality of the five-star leg, and water in the raw materials can be effectively removed through drying; high-speed filling of filler is conducted, the filling speed is 0.35L/s, and high-speed filling can facilitate injection molding and prevent air from entering the melt to form bubbles; the die cooling temperature is 28 DEG C, and the die cooling temperature is the same as the working environment temperature, and thus the influence of the outside temperature on forming of the five-star leg can be avoided during demolding; the edges, with burrs, of the five-star legs are polished by means of abrasive paper, in this way, the burrs on the edges of the five-star leg can be rapidly removed, and the five-star leg is prevented from being damaged.
