Plastic chairs are information
The plastic chair is created by designing the chair mold, establishing the model of the plastic chair mold, and then manufacturing the chair mold, and then selecting the appropriate injection molding machine to create an efficient plastic chair molding line. The injection pressure is adjusted to control the injection speed and maintain the appropriate pressure and Temperature so that the plastic chair can be better molded in the mold, and finally the chair obtained is cooled and demolded.
Plastic chair material introduction
PP plastic, also known as polypropylene plastic, is another excellent resin species developed after nylon. It is a semi-crystalline material with obvious advantages, excellent mechanical properties and heat resistance, and extremely high non-hydrophilic properties. Sex, almost no water absorption. The disadvantage is poor low-temperature impact resistance and easy aging. But compared with PE plastic, it has a higher melting point.
PE plastic is polyethylene plastic, and its corrosion resistance and electrical insulation are very strong. Rigidity and strength are relatively high, the same as PP plastic, and its water absorption is also very small.
