What are the acceptance standards for injection molds?

The acceptance standard of injection mold is to ensure that the quality and performance of the mold meet the design requirements, so as to ensure the stability of the production process and the quality of the product.

The following are the 7 main factors of injection mold acceptance criteria:

(1) Appearance inspection:
First of all, the appearance of the mold needs to be checked. Including whether there are obvious scratches, bubbles, cracks and other defects on the mold surface, and whether the size and shape of the mold are consistent with the design requirements.

(2) Material quality:
The material quality of the die directly affects the service life and performance of the die. It is necessary to check the quality documentation of the mold material to ensure that the material meets the relevant standards and that there are no defects such as inclusions and pores.

(3) Dimensional accuracy:
The dimensional accuracy of injection moulds is critical to product quality and assembly requirements. It is necessary to check whether the dimensional accuracy of the mold meets the design requirements, including the overall size of the mold, the aperture size, parallelism, perpendicularity, etc.

(4) Quality of injection parts:
The ultimate purpose of the mold is to produce injection parts that meet the requirements. Therefore, it is necessary to check the injection parts produced by the mold, including the size, appearance quality and physical properties of the injection parts.

(5) Mold life:
The life of die is one of the important indexes to evaluate the quality of die. According to the design life of the mold and the conditions of use, the life test or simulation test of the mold is needed to assess whether the service life of the mold meets the requirements.

(6) Mold test:
In the acceptance process, it is usually necessary to carry out mold testing to verify the performance and stability of the mold. Through the test mold can check the mold demoulding situation, product surface quality, dimensional accuracy, etc., and make necessary adjustments and improvements.

(7) Mold documents and information:
Finally, it is necessary to check the documents and information of the mold, including mold drawings, technical documents, operating manuals, etc. These documents and information are very important for the maintenance, maintenance and repair of the mold.

To sum up, the acceptance standards of injection molds mainly include appearance inspection, material quality, dimensional accuracy, quality of injection parts, mold life, mold trial and mold documents and information. Through inspection and testing in strict accordance with the acceptance standards, the quality and performance of the mold can be ensured to meet the requirements, thereby improving production efficiency and product quality.
