HDPE CNC Machining Services

Chair produced by CNC Machining HDPE using CNC RouterMF Engineering is a premier manufacturer of high-precision components for customers across a wide range of industries. We offer a variety of computer numerical controlled (CNC) machining capabilities for metals, plastics, and other materials. Two of our core service offerings include CNC routing and CNC milling for HDPE. We also provide fabrication and assembly services to facilitate the delivery of complete HDPE parts and products to customers.

High-density polyethylene (HDPE) is a thermoplastic that demonstrates numerous characteristics that make it suitable for CNC machining operations, such as excellent machinability and rigidity. Its low moisture absorption also makes it appropriate for marine applications, while its availability in FDA-compliant and USDA-certified grades makes it a viable option for food and beverage, medical, and other sanitary industry applications.

Our HDPE CNC Machining Services

Our HDPE CNC machining services include CNC routing and CNC milling. With our CNC technology for these operations, we are able to achieve better product quality, greater process consistency, and faster production speeds, all of which benefit our customers. Additionally, it allows us to easily fulfill project orders regardless of part complexity or production quantity.

CNC Routing

Routing is a machining process that utilizes a rotating cutting tool to cut various shapes and edges into a flat workpiece. It is used for rigid non-metals (e.g., plastics, foams, and wood) and soft metals (e.g., aluminum, brass, and copper).

Our CNC Router offers three-axis, CNC-controlled routing capabilities with tolerances of ±.0625 inches for HDPE parts. We also utilize a 3D templating digitizer to aid in digital conversion of patterns and spatial constraints to fit a custom profile. Other relevant services include:

  • Multi-hole drilling (nine-position drill bank)
  • Horizontal machining (with the use of an aggregate head)
  • CAD design
  • CAM programming
  • Reverse engineering

CNC Milling

Similar to routing, the CNC milling process relies on rotating cutting tools to create the desired parts and products. In addition, our CNC milling services can be used with soft materials (e.g., plastics and wood) and hard materials (e.g., steel and titanium).

Our CNC vertical machining centers allow us to offer three-axis and four-axis milling capabilities for HDPE parts up to 26 inches (length) by 14 inches (width) by 12 inches (height) with tolerances of ±.001 inches. We also provide the following services:

  • CAD Model data extraction
  • CAM programming
  • Reverse engineering

Fabrication and Assembly

In addition to our machining capabilities, we also offer fabrication and assembly services for HDPE parts and products. We can fabricate products by combining standard hardware with custom-machined components. We can assemble multifaceted components to meet virtually any customer specifications, including for aerospace, marine, and medical applications. MF Engineering will work with you to bring your custom HDPE projects to life.

Benefits of Using HDPE for CNC Machining Operations

As indicated above, HDPE is an excellent material for CNC machining operations. Some of the other properties that make it a viable option include:

  • High strength-to-density ratio (better tensile strength than LDPE—20 MPa or 2,900 PSI)
  • Durability (resistance to chemical, corrosion, impact, and solvents)
  • High melting point 266° F (130° C)

Considerations for HDPE CNC Machining Operations

While HDPE is often used in CNC machining operations, it can be challenging to machine under the wrong processing conditions. Some of the considerations to keep in mind when machining HDPE include:

  • Processing speed. High speeds are required when routing or milling HDPE.
  • Internal stress. The heat generated by cutting into the workpiece can cause cracking and other damage due to the material’s internal stresses, especially when the material is cold. Annealing the HDPE before routing and milling operations minimizes the risk of this occurring.
  • Cutting chips. During machining operations, the chips generated by the act of cutting into the workpiece can clog the equipment. Compressed air & vacuum systems can be used to clear the chips from the workpiece. They also help maintain close tolerances, achieve good surface finishes and minimize dust & debris.
