滚塑工艺的点是： 

1, 滚塑产品边缘强度好，滚塑可以实现产品边缘的厚度过5个毫米，解决中空产品边缘较薄的问题； 
2，滚塑可以安置各种镶嵌件； 
3，滚塑产品的形状可以非常复杂，且厚度过5个毫米； 
4，滚塑可以生产全封闭产品； 
5，滚塑产品可以填充发泡材料，实现保温。 
6，无须调整模具，滚塑产品的壁厚可以自由调整（2mm以上）。 
7，产品中空无缝，但可以调整壁厚，使产品具高强度。 
8，可提供多种表面花纹理，生产各种颜色制品，可作老化理，作多种石质，木质仿真效果。

The characteristics of rotational molding process are as follows:

1. The edge strength of rotational molding products is good, and the thickness of product edge can be more than 5 mm, which can completely solve the problem of thin edge of hollow products

2. All kinds of inlays can be placed in rotational molding

3. The shape of rotational molding products can be very complex, and the thickness is more than 5 mm

4. Rotational molding can produce fully enclosed products

5. The rotational molding products can be filled with foamed materials to achieve thermal insulation.  

6. No need to adjust the mold, the wall thickness of the rotational molding product can be adjusted freely (more than 2mm).  

7. The product is hollow and seamless, but the wall thickness can be adjusted to make the product have high strength.  

8, can provide a variety of surface pattern processing, production of various color products, can be used to prevent ultraviolet and anti-aging treatment, for a variety of stone, wood simulation results.
