1. The overall thickness of small parts of electronic cigarettes should be more than 1.2mm, with the limit of 1.00mm, and the thickness of the overall rubber position of large products (door locks, broom covers, large panels) should be more than 2.5mm.
2. The slope (die angle) of the product edge shall be more than 3 degrees.
3. If the CNC process is not used for the white edge, the standard of the normal white edge is 0.50MM, and the limit is 0.30mm.
4. The minimum R angle on the appearance shall be 0.5mm. If the sheet is too small, it will crack, have fine cracks and run away.
5. The thickness of the rear formwork bone position shall be 0.60 mm, and the exit angle of the rear formwork bone position shall be 0.5 degrees
6. The rubber position has the structure of stealing rubber position, groove and sink table. The drop shall not exceed 0.30mm. The edge shall be large and the transition shall be smooth. Otherwise, the subsequent process CNC processing is required
7. When the mold is inserted, there should be no structure of R angle/C angle at the back of the edge to prevent the mold from inserting through the thin steel.
8. IML process products have deformation after film coating, which is generally internal arch, and the deformation is more than 1.00mm.
9. If the IML process is 2D cutting, the edging can only be wrapped to the R side, and cannot be wrapped to the bottom.
10. If IML process products have through-holes, the die angle should be more than 3 degrees.
11. If IML process products have through-holes, the through-hole diameter should be more than 1.0mm, which can only be realized by CNC machining.
12. For large products (door lock, broom cover, large panel), the outer diameter of the screw column should be 4.2-4.3mm, and the inner hole should be 2.70mm to prevent the surface screw column from shrinking the watermark. At the same time, pay attention to the thickness of the glue between the inner and outer diameters of the screw column should be 0.7-0.8mm.
