Unlock The Unique Advantages of Rotomolding Mould

Rotational molding molds have significant advantages over other forming molds (such as injection molding, blow molding) in specific scenarios, mainly reflected in the following aspects:

 

 

 

 

1 Suitable for complex shapes and large products

• Rotational molding molds have better adaptability to product structures, especially suitable for producing items with complex curved surfaces, hollow structures, or large dimensions (such as large tanks, amusement facilities, hulls, etc.), without considering structural interference issues during mold opening and closing.

 

• Good integral forming capability reduces product assembly and enhances overall strength.

 

2  Cost advantages are evident:

• Low mold manufacturing costs: The structure is relatively simple, requiring no complex gating systems or clamping devices, especially for large molds, where costs are significantly lower than injection molds.

 

• More economical for small batch production: Suitable for small batch, multi-variety production without bearing high mold amortization costs, offering higher flexibility.

 

3 Product performance is more stable:

• Ensures uniform wall thickness of products, reducing deformation, cracking, and other defects caused by wall thickness differences, enhancing impact resistance and service life.

 

• Strong adaptability to raw materials, allowing the use of various plastics (such as PE, PVC, PP, etc.), and even achieving composite material molding.

 

4 High design freedom:

• No need to overly consider the impact of raw material flow pressure on the mold during mold design, enabling more flexible realization of personalized product designs (such as special textures, multi-color one-piece molding, etc.).

 

These advantages make rotational molding widely used in large hollow products, irregular structural components, and other fields, particularly suitable for scenarios with high requirements for cost and structural complexity.
