Four advantages of rotational molding process

Injection mold processing

Injection mold processing is to first add plastic into the mold, and then the mold is continuously rotating and heated along the two vertical axes. Under the action of gravity and heat energy, the plastic in the mold is gradually evenly coated, melted and adhered to the whole surface of the mold cavity, and is molded into the required shape to be cooled and shaped.

Rotational mold processing

The method of rotational molding is that the plastic is added into the mold, and then the mold is continuously rotated and heated along the two vertical axes. Under the action of gravity and heat energy, the plastic in the mold is gradually evenly coated and melted, adhering to the whole surface of the mold cavity, forming into the required shape, and then cooling and shaping.

Compared with traditional blow molding and injection molding processes, rotational molding has the following advantages:

1. Cost advantage:

In the rotational molding process, only the strength of the frame is required to support the weight of the material, the mold and the frame itself, so as to prevent the material from leaking. In addition, in the whole molding process, the material is hardly affected by any external force except the natural gravity, so it has the advantages of convenient machining and manufacturing, short cycle and low cost.

2. Quality advantage:

Because there is no internal stress in the whole production process, the product quality and structure are more stable.

3. Flexible advantages:

The rotational molding process is easy to manufacture and low in price, so it is especially suitable for the multi variety and small batch production in the development of new products.

4. Advantages of personalized design:

The products in the rotational molding process are easy to change color, and can be hollow (seamless without welding). The surface treatment of products can achieve the effect of pattern, wood, stone and metal, so as to meet the personalized needs of consumers in modern society.

The products produced by this process include: oil tank, water tank, mechanical shell, mudguard, etc. The main substitutes are metal parts and FRP products.

Injection molding is a kind of process, which is based on the micro manufacturing technology such as Liga. Of course, there are many other methods. The Liga process is to produce a model needed for injection molding, which is commonly known as "mold", and then the liquid plastic is poured into the mold, and finally separated to form the final product required.
