1. In terms of the pieces of injection molding

Raw materials of injection molding, the coordination between movable molding and fixed molding, the diameter of screw, the pressure of injection molding and the dwell time are all the key factors; If it isn't implemented in line with the standard and the technology won't be locked in, on one hand, the passing rate of the pieces of injection molding will decrease drastically, on the other hand, the reliability of spare parts will not be guaranteed, and a series of problems will come up, such as the fracture of the clamping claw, the cracking of the optical lens and excessive fog test.

2. In terms of aluminum piece

It should guarantee the environment cleanliness of the aluminum piece, the pretreatment of the workblank pieces and the coordination between fixture and spare parts, otherwise it will also bring about the problems of the shedding and cracking of plating aluminum layer.

3. In terms of the assemblage of headlights

The trajectory control of the cloth tape technology, the blaze pretreatment before cloth tape, the inflation pressure and the dwell time of the airtight test. The error of any working procedures will lead to the problems of water seeping.

4. In terms of the assemblage of rear lights

The temperature of the welding of thermal plate, the level judgment of welding quality.
