1. Why are there vents on the surface of rotomolded products?

（1）Rigid process requirements - exhaust is the "lifeline" of rotational molding

（2）The location of the exhaust hole cannot be completely hidden

（3） Air pressure balance during the cooling stage



2.How to reduce the impact of exhaust holes on the surface?
（1）Design optimization

（2） Process improvement

（3）Post-processing

Here are some steps and precautions for how to evenly wear the surface of the roto-molded finished product:

1. Choose the right abrasive

2. Determine the purpose of wear

3. Control the intensity and speed of wear

4. Uniform wear

5. Pay attention to safety

1. High design freedom and flexible modeling

2. Lightweight, easy to install and transport

3. Strong durability and wide application environment

4. Low cost, suitable for small batch customization

5. Diverse surface treatments and rich textures

6. Environmental advantages

7. Functional expansion



Typical application scenarios
Home decoration: art ornaments, imitation stone flower pots, creative lampshades.

Commercial space: shopping mall art installations, corporate LOGO sculptures, theme restaurant decorations.

Outdoor landscape: park sculptures, imitation wood railings, holiday decorations (such as Christmas trees, pumpkin lanterns).

Summary
The core advantage of roto-molded decorations lies in "low cost to achieve complex design" + "lightweight and durable", which is particularly suitable for scenes that require personalization, small and medium batches, and outdoor use. It is a high-quality alternative to traditional metal and ceramic decorations.

3. Alternative solutions for remodeling

4. Key steps before remodeling

1. Clarify production needs

Before choosing rotomolding equipment, enterprises need to clarify their own production needs. This includes determining the type, specification, quantity and production process requirements of the plastic products to be produced. Understanding this basic information will help enterprises determine the specifications and performance requirements of the required equipment.

2. Consider equipment performance parameters

Specifications and capacity: According to production needs, select suitable equipment specifications and capacity to ensure that the requirements of production efficiency and output can be met.

Precision and stability: The precision and stability of the equipment have an important impact on product quality. Choosing equipment with high precision and high repeatability can improve the qualified rate and stability of the product.

3. Understand market reputation and after-sales service

Market reputation: Understanding the reputation and user evaluation of rotomolding equipment in the market will help to judge the performance and quality of the equipment. Choosing brands and manufacturers with good reputation can reduce the risk of purchase.

4. Consider budget and return on investment

Budget range: Set a reasonable budget range and select and configure the equipment according to the budget. At the same time, consider long-term operating costs, such as maintenance costs and consumables costs.

5. Actual inspection and comparison

Field inspection: Enterprises with conditions can inspect the equipment manufacturers on site to understand the actual operating conditions, production efficiency and process flow of the equipment. This will help enterprises to evaluate the performance and quality of the equipment more comprehensively.

1. Not considering wall thickness distribution

2. Overly complex mold features

3. Insufficient draft angles

4. Ignoring shrinkage tolerances

5. Ignoring proper venting of the mold

6. Designing with inconsistent surface textures

7. Underestimating the cooling stage in the design

8. Improper placement of reinforcements

9. Insufficient consideration of post-molding processes

Reinforcement ribs are a method often used in roto-molded products to increase strength. They not only make the wall thickness of the product uniform, but also save materials, improve strength, and avoid appearance defects of the product. Since some roto-molded products are large flat thin-walled products, the surface of the product is more prone to warping and deformation, and the strength is not high. Therefore, in order to increase the rigidity and strength of the large plane and the stress-bearing part of the product, it is necessary to consider designing reinforcement ribs on the corresponding surface of the roto-molded product. Moreover, products designed with reinforcement ribs can also use less raw materials and molding time to achieve the same strength, which makes the wall thickness, strength and cost better coordinated.

As for the size of the reinforcement rib, there are three elements: length, width and height. The height here refers to the size of the reinforcement rib protruding from the wall. The strength of the reinforcement rib is mainly determined by this height. Generally speaking, the design height of the reinforcement rib should be at least 4 times greater than the average wall thickness of the product to greatly enhance the strength of the product. The width of the reinforcement rib should be designed to be at least 5 times the average wall thickness of the product to provide enough space for the powder or liquid to flow into the cavity. If the space is too narrow, the raw material cannot flow into this part of the mold cavity evenly, resulting in bridging, internal porosity and increased shrinkage of the product.
