Describe In Detail The Common Precision Requirements For Rotational Molding

Rotomolding is a common processing technology, mainly used to produce plastic products.

In the process of rotomolding, precision requirements are very important.

High precision can ensure the quality and performance of the product and meet the needs of customers.

The following are common precision requirements for rotomolding.

1. Dimensional accuracy:

Products processed by rotomolding usually require accurate dimensional accuracy. Dimensional accuracy refers to the deviation between the size of the product and the design requirements.

Usually expressed as tolerance, the smaller the tolerance, the higher the dimensional accuracy.

Rotomolding needs to control the dimensional accuracy during product design and processing according to customer requirements to ensure that the size of the product meets the requirements.

2. Shape accuracy:

Shape accuracy refers to the deviation between the shape of the product and the design requirements.

Rotomolding usually needs to ensure the shape accuracy of the product so that the shape of the product meets the design requirements.

Shape accuracy includes indicators such as flatness, verticality, and roundness, which can be guaranteed by appropriate production processes and processing equipment.

3. Surface accuracy:

Surface accuracy refers to the accuracy requirements of the flatness and smoothness of the product surface.

The flatness of the product surface can be measured by measuring the height difference of the surface, and the smoothness can be measured by measuring the roughness of the surface.

Rotomolding usually needs to ensure the surface accuracy of the product to improve the appearance quality and functional performance of the product.

4. Fitting accuracy:

Fitting accuracy refers to the accuracy requirements between the matching parts of the product.

During the rotomolding process, the product usually needs to be assembled and matched with other parts,

Therefore, it is necessary to control the matching accuracy of the product to ensure the assemblability and performance of the product.

Matching accuracy mainly includes indicators such as clearance, fit, and matching force.

5. Repeatability accuracy:

Repeatability accuracy refers to the consistency of the size and shape accuracy of the same product in multiple productions.

Rotomolding usually needs to ensure the repeatability accuracy of the product in different production batches to ensure the consistency and replaceability of the product.

6. Material accuracy:

Material accuracy refers to the accuracy requirements of the materials used in the product.

Different materials have different physical properties and process properties. Rotomolding requires the selection of suitable materials,

and ensures the quality and accuracy of the materials to ensure the service life and safety performance of the product.

In general, the accuracy requirements of rotomolding take into account factors such as size accuracy, shape accuracy, surface accuracy, fit accuracy, repeatability accuracy and material accuracy. Through scientific design and accurate processing technology, rotational molding can meet the precision requirements of different customers and provide high-quality rotational molding products.
