1、gating system

Has the pouring system undergone CAE analysis and is there an analysis report for customer confirmation;

2. Whether the material channel, gate type and size, gate number, position, and structure are correct, reasonable, and balanced, and whether they are clearly expressed on the drawing (the standard requires the gate to be enlarged by 4 times);

3. Whether the gate automatically falls off and whether the gate affects the appearance of the product;

4. Whether the composite cavities, flow channel distribution, and injection pressure of products with multiple cavities and non identical products are balanced;

5. Whether the main channel design of the mold is too long or too short, whether the feeding point of the sprue sleeve is too deep from the fixed mold panel of the injection molding machine, and whether the relevant dimensions of the sprue sleeve are correct;

6. Is there a cold material well (also known as a cold material hole) installed in the material channel, and is there a material channel exhaust;

7. Does the mold with multiple cavities have a separate channel conversion structure;

8. Are there any blind spots at all intersections and turning points in the flow channel;

9. Whether the structure of the material pulling rod is reasonable and meets the customer's requirements;

10. Whether the electrical power of the flow channel plate and heating coil of the hot runner meets the requirements;

11. Whether the nozzle of the hot runner is leaking or blocked, and whether the design is reasonable;

12. Is there a rounded transition at the corner of the wire trough (with a minimum radius of 6.5mm);

13. Are all wires numbered and assembled in a distribution box using protective tubes;

14. Is a pressure sensor necessary and is the design reasonable;

15. If the feed inlet is eccentric, is the eccentricity designed according to the standard, and is the top outlet hole synchronized with the offset.

2、mold temperature control

Is there a corresponding feeding port number engraved on the flow channel plate of the hot runner with multiple nozzles;

2. Whether the structure of the cooling water circuit is reasonable and follows the design principles and standard requirements of the cooling water circuit;

3. Is the cooling water pipe interface set on the reverse operation surface;

4. Whether the position and size of the cooling water channel are correct and meet the requirements of the forming process;

5. Whether the size and depth of plugs, water separators, water pipe joints, and sinkholes meet the requirements;

6. Are there splitters installed on waterways with three or more channels, and are they located on the reverse operation surface;

7. Are beryllium copper, heat dissipation rods, or copper alloys used for mold structures with poor cooling effects;

8. Whether there are signs for entering and exiting waterways, grouping with "IN" for entry and "OUT" for exit, and nameplates for schematic diagrams;

9. Are the thread specifications (NPT, PT, PS, PF) of the cooling water pipe joints correct;

10. Is there a cooling water structure near the flow channel or hot runner nozzle.
