Inspecting the injection mold is an indispensable step in injection molding. It is related to whether the injection molding production can be started normally. If the injection mold inspection is not passed and the production operation is carried out directly, the injection mold base or the injection molding machine equipment may be damaged.

Therefore, before injection molding production, it needs to be carefully inspected by a professional mold inspection company or mold engineer before injection molding production can be carried out.

Mold inspection process

The injection mold inspection process usually includes multiple steps to ensure mold quality and production efficiency.

The following is the general injection mold inspection process:

Visual inspection

Check the appearance of the mold to ensure that the surface is smooth and has no obvious damage or wear. Appearance quality is directly related to the appearance of the final product.

Dimensions

Use measuring tools, such as calipers, projectors, etc., to measure the critical dimensions of the mold. Ensure the dimensions are accurate and meet design requirements.

Material quality inspection

Inspect the materials used in the mold to ensure they meet the requirements. This may involve the use of materials testing equipment such as tensile testing machines, durometers, etc.

Mold assembly inspection

Check the assembly of various parts of the mold to ensure that each part is installed correctly. This also includes checking the cooling system, nozzles, etc. of the mold.

Flow system inspection

Inspect the runner system of the injection mold to ensure that the molten plastic can flow evenly into the mold cavity. This can be done through injection molding simulation or trial molding.

Temperature control check

Check the mold's temperature control system to ensure it provides even temperature distribution. This is crucial to avoid product defects.

Injection system inspection

Check the injection system, including screw, heater, nozzle, etc., to ensure they are working properly. This can be verified by test firing.

Loop simulation test

Carry out cycle simulation testing of the mold to simulate actual production conditions and check the stability, durability and possible problems of the mold.

Trial mold output inspection

Carry out mold trials and produce some samples for inspection. This can help detect potential production issues and verify that the mold meets product quality standards.

Modify and adjust

If problems are found during inspection, make corresponding modifications and adjustments. Multiple rounds of testing and adjustments may be required until the mold meets production needs.

These steps usually need to be performed by experienced engineers and technicians to ensure the high quality and reliability of the injection mold.

Free mold inspection company

Universe Plastic Factory can provide injection mold inspection and storage services free of charge, and can also repair and optimize unqualified injection molds. However, without mold inspection report materials, it can only ensure that the injection mold can be produced and used normally in injection molding projects.
