ポリエチレン射出成形
射出成形プロセスでは、まずPE粒子を加熱して溶かす必要があり、次に溶けたPEを金型に射出し、冷却して成形した後、目的の製品が得られる。ポリエチレンの射出成形プロセスは簡単、低コスト、高効率であり、包装、建築、電子、医療、家庭などの分野で広く使用することができます。
Polyethylene Injection Molding Process
Polyethylene injection molding is divided into high-density polyethylene (HDPE) and low-density polyethylene (LDPE). The main difference between them is the density. We also choose polyethylene with different densities according to your materials. what is the difference
HDPE injection molding
HDPE has a higher density than LDPE, typically between 0.95 g/cm³ and 0.96 g/cm³. Since the molecular chain of HDPE is shorter than that of LDPE, its crystal molecular locking is stronger, HDPE is harder and more durable than LDPE, and its physical properties are superior, such as high strength, high hardness and higher melting point. Therefore, HDPE is usually used to manufacture products with high strength, high durability and high quality requirements.
LDPE injection molding
LDPE has a lower density, usually between 0.91 g/cm³ and 0.925 g/cm³. LDPE is very soft and easier to shape and process than HDPE. Due to the long molecular chain of LDPE, the inter-molecular gap is large, and it has high flexibility, smooth surface, heat insulation and sound insulation. Therefore, LDPE is usually used to manufacture products with low strength, low durability and low quality requirements.

Application of Polyethylene Injection Molding
LDPE is usually used to make plastic bags, garbage bags, plastic film and other packaging purposes, while HDPE is often used to make water pipes, chemical barrels, food containers, etc. Both LDPE and HDPE are excellent plastic materials, and different materials can be selected according to different application scenarios.
