The starting method of the extruder for producing the
polypropylene thin-wall injection molding product comprises the following steps: step 1, selecting a ZSK type double-screw extruder, and setting various initial working parameters of the extruder; step 2, starting an extruding
machine, and carrying out material pulling on the template; 3, after template material pulling is completed, template seepage materials are cleaned, and after cleaning is completed, die
assembly is conducted on the granulator; step 4, observing the shape of the granules at the sampling port, and if the granules are large and many, lifting the load of the extruding
machine to adjust; according to the method, only the process parameters of the ZSK type double-screw extruder are adjusted, operation is easy, modification does not need to be added, and universality is good; meanwhile, by determining the optimal process parameters, the finally obtained
polypropylene thin-wall injection molding product particles are regular in appearance, the operation
power consumption of an extruder granulator is effectively reduced, and the wear of a cutter of the granulator is reduced.
