    What is HDPE CNC Machining?

    HDPE CNC machining is the subtractive manufacturing way to make components. This method will result in consistent dimensions, clean edges; repeatable results, even for high volume runs. It is an ideal solution for clients who need plastic components with tolerance and mechanical properties.

      How HDPE CNC Machining Works?

      HDPE CNC machining refers to processes of removing material from solid HDPE sheets or blocks with the aid of computer-controlled machines. The process involves milling, drilling, turning, and routing, which are all done using specialized tooling so as to avoid deformation. Since the HDPE is soft relative to the metals, the factors that are critical for producing clean and accurate parts are speed, tooling sharpness, and cooling.

            HDPE Material Properties

            Here are some of the prominent properties of HDPE material：

            HDPE Material Properties

            Chemical & Moisture Resistance

            HDPE is good with harsh chemical environments and humid conditions. Its non-reactive surface is suited for the applications of corrosive settings such as chemical tanks, lab equipment, or marine applications.

            Moderate Heat Resistance

            At 120° C, it is possible to safely run an HDPE system as no softening or warping occurs, and the structural integrity is retained. Although not ideal for extreme heating, it performs well in industrial and consumer settings.

            Impact Resistance

            This material has outstanding toughness, and it does not crack or break when subjected to impact. Its strength makes it ideal for components, which are subject to physical stress or are to be handled a lot.

            FDA-Approved Grades Available

            Virgin HDPE comes in FDA-compliant variants, thus, it is safe for making direct food contact and use in cleanrooms. It is widely used in the field of food processing, packaging, and medical applications.

            Low Friction & Water Absorption

            HDPE is hydrophobic by nature and is also virtually for fluid flow applications. Its low coefficient of friction also minimizes wear in moving parts and guides.

              Surface Finishes Available at TOPS

              Let’s discuss some of the common surface finishing options available at TOPS

              Standard Machined Finish

              This is the standard finish on CNC machining – a bit rough, but clean and functional. It appropriately applies to most industrial or hidden parts applications, where the appearance is not important.

              Bead Blasting

              HDPE will have a matte, even finish obtained from bead blasting, thus helping to reduce glare and allowing for greater grip. It’s great for visible components or for parts that would need a tighter finish.

              Deburring & Polishing Edges

              Edges that are sharp or rough are smoothed out in the process of machining for safer handling and better assembly fit. Polishing also enhances the area of the part with regard to the appearance and the functional contact points.

              Custom Markings

              We provide silk screening, laser engraving, or printed labeling to put logos, part numbers, or compliance information directly onto the part – ideal for branding or traceability.

                  Considerations For HDPE CNC Machining Operations

                  Here are some of its main considerations：

                  1. HDPE can be deformed at high cutting stress.
                  2. Controlled feeds and sharp tools go a long way in minimizing melting.
                  3. Prevent overheating to retain dimensional accuracy.
                  4. Fixturing is very important because of low stiffness.
