Plastic chair injection mold

Being a human being, we all need a chair while we would like to take a rest.  Chairs play an important role in our lives. We need chairs when we are working in the office or studying at school.  We need chairs when we go home and take a rest. Even when we are traveling or shopping outside, we need chairs even more when we are tired.  Chairs come in a variety of materials, including wood, metal, ceramic, paper, cotton material, leather material or plastic. However, if you want to mention the innovative design of the chair, the portability of the chair and the storability, the plastic chairs are better than the chairs made of other materials.

Normally plastic chairs are made by injection molding.  The material is PP because PP material has the characteristics:

1. Cheap: In terms of the cost of plastic raw materials, PP is a relatively cheaper raw material among all plastic categories.

2. Easy to form: The biggest feature of PP is that it is very easy to be formed and is not prone to overheat cracking.

3. Stable physical properties: Since PP is a crystalline material; it has good thermal stability and chemical resistance.

4. Easy to recycle: The density of PP is less than 1, and its physical properties are stable and easy to process. Therefore, PP is one of the easiest plastics to be recycled. In addition, PP is not easy to produce other toxic substances in the process of heating and plasticizing.
