Abstract
The application provides a processing technology for producing a plastic-coated retainer, comprising the following steps: step one, drying granular raw materials in a drying machine at a set temperature for a set time period, so that the water content of the materials is reduced to below a preset standard; step two, accurately placing the pretreated metal skeleton in an injection mold cavity; step three, using an injection molding machine to perform injection coating under the condition that the nozzle temperature is 180-220 DEG C; and step four, after molding, taking out the workpiece by a mechanical hand and placing it on a conveying belt, and performing forced air cooling at a set wind speed for a set time period under room temperature conditions, so that uniform cooling is realized. The problems that pores are prone to occurring in products in a traditional process, and that a huge residual stress accumulated at the interface between metal and plastic and inside plastic leads to delamination are solved.
