What is HDPE?
HDPE, sometimes called PEHD (polyethylene high-density), is part of the polyethylene (PE) family of plastics. It is a high-impact, high-density crystalline thermoplastic. It also has low moisture absorption, good chemical resistance, and corrosion resistance. Compared to its sibling, low-density polyethylene (LDPE), HDPE has higher impact and tensile strength. This polymer has a melting point of 266°F (130°C). Its tensile strength is 20 MPa (2900 psi). High-density polyethylene (HDPE) comes in two grades: 300 and 500. The main difference between these two grades is density. Typically, HDPE density ranges from 0.955 g/cm³ to 0.961 g/cm³. Yield strength ranges from 23 to 29.5 MPa. High-density polyethylene (HDPE) plastic has a crystalline structure with extremely low branching, resulting in superior mechanical properties compared to low-density polyethylene (LDPE).
What is HDPE CNC Machining?
HDPE CNC machining refers to the process of removing material from HDPE sheets or blocks using computer-controlled machine tools. This process includes milling, drilling, turning, and cutting, all requiring specialized cutting tools to prevent deformation. Because HDPE is softer than metal, the key factors for producing clean, precise parts are machining speed, tool sharpness, and cooling efficiency. This method ensures consistent dimensions and smooth edges, achieving repeatable results even in high-volume production. It is an ideal solution for customers requiring plastic parts with high tolerances and excellent mechanical properties.

The HDPE Grades We Use
Our machining services can process high-density polyethylene (HDPE) sheets, rods, and pipes in various specifications. There are two main grades: Grade 300 and Grade 500. These numbers indicate the density of the material. The higher the number, the greater the density of the thermoplastic, or the higher the molecular weight. Elimold can source HDPE materials from many brands, such as HiTec, Playboard, Polystone, etc. Both grades are usually available in black or white. In addition to the two main grades, 300 and 500, HDPE is also divided into HDPE certification grade, marine grade HDPE, and HDPE pipe grade.
