The invention discloses a production process of plastic polyester dyeing pipes. The production process includes the steps of firstly, evenly stirring, by weight percentage, 40-60% of synthetic resin, 20-35% of filler, 5-8% of plasticizer, 1-3% of stabilizer, 0.5-2% of flame retardant and 0.3-0.8% of antistatic agent in a stirring device; secondly, heating the mixed raw materials obtained in the first step in a high-temperature heating furnace until the mixed raw materials are molten; thirdly, using an injection molding machine to perform extrusion molding on the molten raw materials; thirdly, performing surface finishing, to be more specific, using filing, grinding and polishing to remove the burrs on products, and correcting sizes; fifthly, packaging the products after the surface finishing.
