Embodiment 1

[0032] A PA-GF30 material of the present embodiment is coated with a front-end module injection molding process of sheet metal, and its steps are as follows:

[0033] Step 1. Raw material pretreatment: use an oven to dry the PA-GF30 material at a temperature of 95-105°C for 4 hours.

[0034] Step 2. Equipment pretreatment: heat the barrel of the injection molding machine to 250~290°C, and heat the screw of the injection machine. The heating temperature of the screw of the injection machine is 260~280°C; heat the hot runner in the injection mold to 300~ 310°C, heat the temperature of the moving mold in the injection mold to 75~80°C, and the temperature of the fixed mold to 80~85°C; in step 2, the heating temperature of the screw of the injection molding machine is divided into 6 sections, from the nozzle of the injection molding machine to the back of each part The heating temperature of the screw is as follows:

[0035] 1: 240~260°C; 2: 285~305°C; 3: 280~300°C; 4: 280~300°C; ...

Embodiment 2

[0055] In this embodiment, a front-end module injection molding process in which PA-GF30 material is coated with sheet metal is basically the same as in Embodiment 1, except that in this embodiment, the barrel of the injection molding machine is heated to 290°C , heat the temperature of the moving mold in the injection mold to 75°C, and the temperature of the fixed mold to 80°C; the injection pressure of the first stage is 85bar, and the injection speed is 48% of the maximum speed; the injection pressure of the second stage is 90bar, and the injection speed is 73% of maximum speed.

Embodiment 3

[0057] In this embodiment, a front-end module injection molding process in which PA-GF30 material is coated with sheet metal is basically the same as in Embodiment 1, except that in this embodiment, the barrel of the injection molding machine is heated to 290°C , heat the temperature of the moving mold in the injection mold to 75°C, and the temperature of the fixed mold to 80°C; the injection pressure of the first stage is 90bar, and the injection speed is 50% of the maximum speed; the injection pressure of the second stage is 95bar, and the injection speed is 75% of maximum speed.

Abstract

The invention discloses a PA-GF30 material coated with metal plate front-end module injection molding process and belongs to the field of injection molding. The process comprises the following steps of 1, raw material pretreatment, 2, equipment pretreatment, 3, plastifying, 4, fixing of a metal plate part, 5, injection molding, 6, pressure maintaining, 7, cooling forming, and 8, demolding. Through the technical scheme, the front-end module injection molding process is simple in step and short in period, and the forming quality of a front-end module is good.

Description

technical field [0001] The invention relates to the field of injection molding, more specifically, to a front-end module injection molding process in which PA-GF30 material is covered with sheet metal. Background technique [0002] Injection molding is a method of producing shapes for industrial products, and products usually use rubber injection molding and plastic injection molding. Injection molding can also be divided into injection molding molding method and die casting method. Injection molding machine (referred to as injection machine or injection molding machine) is the main molding equipment for making thermoplastic or thermosetting materials into various shapes of plastic products using plastic molding molds. Injection molding is realized through injection molding machines and molds. [0003] As a part of the body, the front bracket generally adopts a steel plate welded structure. With the continuous improvement of plastic materials and their processing technolog...
