Excellence in manufacturing depends on injection frisbee quality. Our injection Mold Checklist simplifies this procedure, walking you through the necessary stages to uphold high standards. This checklist is an essential tool for any injection molding expert, as it includes all the necessary steps to optimize injection molding solutions, reduce errors, and increase productivity from original design to final inspection.

Mold appearance and dimension

1. Is the kind of water connector correct? Is there sufficient clearance in the hole for the water connector? The hole's outside border must be consistent and chamfered.
2. Indicate the water lines with "IN," "OUT," and neatly and legibly number them. For instance, INT1, OUT1.
3. Pneumatic or oil connection numbers must begin with the prefix "O" or "G," for example, G IN1, O IN1.
4. The gas, oil, and water plugs' screw threads all match the Tooling datasheet.
5. Are the KO pattern and size up to par?
6. The Locating ring's diameter and fastening type comply with the Tooling specification.
7. The tooling datasheet's sprue bushing sphere radius must be met.
8. The total size of the mold must satisfy the customer's press (tie bar space), and the clamping technique must satisfy the customer's demand.
9. When installing a mold that requires installation instruction, the cavity or core plate should be etched with an arrow that reads "UP."
10. Each part must have a unique number. Moreover, the standard mold datum needs to be etched. 
11. It is not permitted to make any of the components within the home. 
12. Using the right steel is important, and the molding injection company must submit the steel certification.
13. All connection screw threads, including K.O. and eyebolt holes, must be precise.
14. Wear plates should employ oil grooves whose designs adhere to client specifications.
15. The shut-off pieces must fulfill customer requirements and have a disparity in hardness.
16. Does Slide Gib require a dowel pin?
17. Are side locks properly purchased and installed?
18. Cycle Installing a counter as per the mold design sketch.
19. Make a vent opening for the guide bush.
20. Is a dustproof sheet required?
21. Are the slides assembled and properly fit the molding injection company?
22. The PL vent needs to be planned and cut. Is it directly cut to the part location and appropriate for parting?
23. Clearance space should be designed and created in the region beyond the portion wall. There is no need to invest in a grinding machine.
24. Sprue bushing should be OK and should not break.

Ejection, Return, Pull system and Removing

1. Smoothly ejecting, No unique sound, no get stick.
2. Lifter surfaces must be polished, lubricant slots must be made, and heat or nitride treatment must be applied (depending on the client's needs).
3. A & B plate guide pins, guide bushings, and ejector plate guide pins must satisfy client requirements.
4. Uneven ejector pins need to be placed in the molding injection company.
5. The ejecting plate ought to fully retract.
6. A flat-surfaced space block must be utilized for the ejecting stroke.
7. A return spring must be a normal part; it cannot be split or polished.
8. Does the material for the lifter, wedge block, and gib match the requirements of the customer? It must be heat-treated or nitride-treated.
9. Install a restricted switch on a hydraulic cylinder or slide.
10. The lifter stroke or slide must be sufficient to satisfy the requirements.
11. Both the ejector pin and the ejector plate must have the ejector number stamped on them.
12. Return pin top surfaces must be level and free of welding; bottom surfaces cannot have pillows or welding. The required hole clearance is 0.07 mm.
13. Unless otherwise noted, there should be 0.05mm of space between the B plate and the ejector guide pin (Conform to the molding injection company design specification).
14. With a sufficient stroke, the runner stripper plate moves smoothly.
15. The steel dimensions must be examined, and a steel check report must be submitted.

Cooling System

1. Water line seals must be leak-free, and utilize Teflon sealing tape.
2. Is the flow appropriate for cooling? To determine this, a flow metre must be used and the flow value recorded.
3. Cooling manifold installation must be done accurately and by client specifications.
4. The water baffle needs to fit the molding injection company specifications

Cold Runner System

1. Sprue bushing inside surface must be polished to design specifications.
2. It is necessary to polish the runner channel to the drawing standard.
3. For multi-molding injection company, the short-shot has to be tesmolding injection company.

Hot Runner System

1. Specifying the desired kind and size of sockets and installing safety settings is necessary.
2. Is there mold protection equipment placed on the outside of the connection box? The wiring must match the shop's given design.
3. To prevent breakage, wires must be bundled and covered with a plate.
4. When both connector sizes are the same, they must be carefully marked to prevent incorrect assembly.
5. Wires that are visible outside of the mold surface are prohibited.
6. The transition slot that allows the wire to pass through the plate and manifold must be rounded to prevent damage.
7. Does a mold-insulating plate exist? If not, has the consumer given their approval?

Mold Packing

1. The steel type, certification, and heat treatment must satisfy the client's needs.
2. Safety locks (at least two pieces) ought to fulfill the design specification, and a rest hole must be created.
3. The CD's files are full? 
4. Are there any particular requirements for the outside surface of mold?
5. Are all the spare components filled up? And it must be supplied with a thorough list.
6. Mold must be wrapped in a plastic membrane.
7. After marking the positioning direction, spread mold # with lacquer.
8. Everything on the packing list must be packed.

Conclusion

In conclusion, obtaining consistent quality and operational efficiency requires the use of an injection mold checklist. You may drastically lower mistakes, raise the caliber of your output, and increase productivity by using this thorough guidance. By putting this checklist into practice, you can revolutionize your cheap injection molding process and make sure every project surpasses customer expectations and industry standards.
