What Should Be Paid Attention To When Conducting Quality Inspection Of Rotational Molding Molds?

When conducting quality inspection of rotomolding molds, there are some precautions that need to be followed to ensure the quality and performance of the molds.

Here are some common precautions:

1. Regular maintenance of molds:

Rotational molds require regular maintenance and care to ensure their normal operation and extended service life.

Before conducting quality inspection, make sure the mold surface is clean, free of rust and damage, and check whether the various parts of the mold are intact.

2. Check mold dimensions:

Before conducting quality inspection, it is necessary to verify whether the dimensions of the mold meet the design requirements.

Use appropriate measuring tools, such as calipers or micrometers, to measure the various dimensions of the mold, including the external dimensions and the dimensions of the internal structure.

Check whether these measurements match the dimensions required by the design.

3. Check mold material:

Rotational molds are usually made of high-strength materials such as steel.

When conducting quality inspection, it is necessary to verify whether the material of the mold meets the requirements.

Equipment such as metallographic microscopes can be used to check the organizational structure and hardness of the mold material and compare them with the specification requirements.

4. Check the surface quality of the mold:

The surface quality of the rotomolding mold has a great influence on the molding effect and appearance quality of the product.

During the quality inspection, it is necessary to check whether there are defects on the mold surface, such as dents, scratches, oxidation, etc.

It is necessary to confirm whether the surface finish of the mold meets the requirements and there is no rust and corrosion.

5. Check the mold accessories:

Rotational molds usually include many accessories, such as mold cores, mold cavities, etc.

During the quality inspection, it is necessary to check whether these accessories are intact.

Check the interchangeability of the mold core and mold cavity, and ensure that the fitting clearance between them meets the requirements.

6. Perform a trial mold:

Before the quality inspection, a trial mold is required to verify the performance and manufacturing quality of the mold.

Use suitable plastic materials for the trial mold and observe the quality and appearance of the molded product.

Check the product's size, surface finish, and detail accuracy to ensure that the design and manufacturing quality of the mold meet the requirements.

7. Check the mold cooling system:

The cooling system of the mold is crucial to ensure the quality of the molded product and improve production efficiency.

When conducting quality inspection, it is necessary to check whether the cooling system of the mold is unobstructed and whether the cooling effect is good.

Check the layout and size of the cooling holes to ensure that they can evenly cool the mold and avoid thermal stress and deformation.

8. Check the mold identification and documents:

Before conducting quality inspection, it is necessary to check the identification and documents on the mold.

Confirm whether the mold identification is clearly visible, including mold number, manufacturing date, etc.

At the same time, check whether the mold's documents are complete, such as design drawings, process documents and maintenance records.

In short, the quality inspection of rotomolding molds needs to be carried out carefully, including inspections of mold size, material, surface quality, accessories, cooling system, etc. Through strict quality inspection, it can be ensured that the rotomolding mold has good performance and quality, providing guarantee for the production of high-quality plastic products.
