The custom price of rotomolding molds is mainly determined by the following aspects:
1. Mold design and size:
The custom price of molds depends on the complexity of the design and the size of the mold.
Complex mold designs require more man-hours and technology, so the price is higher.
In addition, the size of the mold will also affect the cost of materials and production processes, which will affect the custom price.
2. Material selection:
Different materials can be selected when customizing molds, such as steel, aluminum, plastic, etc.
The cost of different materials varies greatly, so the choice of materials will directly affect the custom price.
Generally speaking, molds made of more durable materials are more expensive.
3. Manufacturing process and working hours:
Mold making requires a series of process flows, such as CNC machining, EDM, wire cutting, etc.
Different process flows require different equipment and working hours, which affects the custom price.
Some complex molds may require multiple process flows, resulting in increased costs.
4. Customization quantity:
Large-volume mold customization can reduce costs because it can achieve production line optimization and resource sharing.
On the contrary, small-batch mold customization is more expensive because it requires more manpower and equipment to adapt to diverse needs.
5. Additional requirements:
Sometimes customers may have some additional requirements for mold customization, such as special materials, surface treatment, additional functions, etc.
These additional requirements will increase costs and increase the customization price.
6. Market supply and demand relationship:
Mold customization prices will also be affected by market supply and demand.
When market demand is low and competition is fierce, mold customization prices may fall.

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.

Next, check whether the size and shape of the rotomolded products meet the design requirements.
You can use tools such as rulers and calipers to measure dimensions, and use mold molds or a 3D scanner to check whether the shape is accurate.
3. Check the structure and connection parts:
Then, check whether the structure of the rotomolded product is solid and whether the connecting parts are complete and sealed.
You can gently pull or shake the product with your hands to check whether there is any looseness or abnormal noise in the structure.
4. Check colors and patterns:
It is necessary to check whether the color of rotomolded products meets the design requirements and whether the pattern is clear.
You can use color cards to compare colors and use a magnifying glass to observe pattern details.

The rotational molding process produced by rotational molding manufacturers is also called rotational molding, rotational molding, rotary molding, etc. It is a hollow molding method for thermoplastic plastics. Rotational molding process is an important branch in plastic molding processing. From small children's toys to automobile plastic parts to huge engineering plastic products. Especially for large and special-shaped hollow products, due to the limitations of the characteristics of traditional processes, they can only be completed by rotational molding.
Common rotational molding raw materials on the market include the following: polyethylene (PE); polypropylene (PP); nylon (PA); polyvinyl chloride (PVC); polycarbonate.
Mosaics give people a familiar feeling. There are always various forms of mosaic products around us since childhood. Most mosaics give people a refreshing and fashionable feeling. Of course, there are also some mosaic patterns that are messy and uncomfortable. This bathroom uses orange-red mosaic tiles, which have a strong lemon-fruit feel, have a refreshing effect and are very visual impact.
Save raw materials. The wall thickness of rotational molding products is relatively uniform and the chamfers are slightly thicker, so the performance of the material can be fully utilized and it is conducive to saving raw materials; in addition, during the rotational molding process, there are no waste materials such as runners and gates. Once debugged, , there is almost no recycled material during the production process, so this process has extremely high utilization rate of materials.
