How are plastic hangers molded by injection molding?

2023-04-19

Do you know how plastic hangers are injection molded?

The injection molding process of such products during production can be roughly divided into six stages: "mold closing, injection molding, pressure maintaining, cooling, mold opening, and plastic hanger disassembly". But have you really understood the steps involved? Here, we can give you some appropriate introductions. If you want to know more, you can take a look.

1. Bottom processing, ensuring the quantity of processing;

2. Blank benchmark alignment, 2D and 3D mold surface allowance inspection;

3. 2D and 3D contour rough machining, non equipment non operational plane machining (including safety platform surface, buffer device surface, pressure plate surface, and side reference surface);

4. Before semi precision machining, aligning the side reference plane can ensure accuracy;

5. Semi precision machining of 2D and 3D contours, precision machining of various device operating surfaces (including retaining device surface and contact surface, insertion device surface and back, punch device surface, waste tool device surface and back, tension spring device surface and contact surface), semi precision machining of various guide surfaces and guide holes, and reservation of precision machining process reference holes and height reference, and recording of data;

6. Check and recheck the machining accuracy;

7. Bench worker setting process;

8. Before precision machining, align the reference plane of the technical reference hole and check the allowance of the insert block;

9. Precision machining contour 2D, 3D, side punching contour and hole location, precision machining process reference hole and height reference, precision machining guide surface and guide hole.
