Molds for roto-molded products The molds used for roto-molding are single-wall closed molds, which give the outer contour of the product but cannot accurately determine the internal contour of the product. The mold material for roto-molding molds is generally selected from ordinary carbon steel plates for welding. The cost of welding molds is relatively low, especially suitable for large roto-molded products. The roto-molding process has the following basic requirements for its molds: the mold is not easy to deform and bend during repeated heating and cooling.
The mold should be equipped with a clamping mechanism that is easy to loosen so that the mold can be tightly closed during the heating and cooling process, and can be easily opened when the product needs to be unloaded and loaded. The design and installation of the roto-molding mold should be conducive to the relative movement of the airflow around the mold surface so that the mold can be evenly heated and cooled.
The roto-molding mold should be equipped with a ventilation duct to prevent the gas in the mold from expanding due to heat during the heating process and squeezing out the molten plastic along the mold seam, and to prevent the negative pressure in the mold from causing deformation of the mold and the product during the cooling process.
When designing the local structure of the mold, try to avoid deep cavities and holes, as well as structures such as reinforcing ribs and solid protrusions, because it is difficult for powdered materials to cover the surface of the above structures.

1. Analysis of causes
Exposed inserts can sometimes be interpreted as poor resin coating, but sometimes this is not the case.
Due to continued cooling and shrinkage after the product is demoulded, the outer surface of the nut insert on the rotomolded product will be higher than the surface of the product, affecting the appearance or use.
When the insert is too close to the side of the product or the distance between the fixed end face of the insert and the mold surface is unreasonably designed,
When they interfere with each other during the rotational molding process, the root of the insert cannot be effectively filled with powder.
A phenomenon similar to the mold filling dissatisfaction during injection molding may also easily cause the insert to be exposed.
2. Solution
Before molding, add a gasket of appropriate thickness and size between the mold and the insert.
It can not only make up for the defects caused by the shrinkage of the product after molding, but also does not affect the appearance of the product.
The insert structural design must be done well. The distance between the fixed end face of the insert and the inner wall of the mold must be appropriate or flush with the inner surface of the mold.
This prevents phenomena such as dissatisfaction with mold filling during injection molding.
The cause of one or several defects in a product is not isolated.
It is often related to a variety of factors, and requires craftsmen to conduct a comprehensive analysis from all aspects of the process route based on the defects that occur.
Consider solutions from the main causes first, and then combine solutions with other non-main causes.
If we solve it as soon as possible, we will avoid detours and produce products with better quality through rotational molding.
The reason for this situation is generally poor structural design of the product or insert.
