Machining LDPE Plastic Properties

LDPE is a versatile thermoplastic combining flexibility, chemical resistance, and impact strength. Its softness allows it to machine cleanly with minimal tool wear, making it suitable for CNC milling and turning of lightweight functional parts.
Tensile Strength, Yield (MPa) Elongation at Break Hardness Impact Strength Heat Deflection Heat Deflection Temperature Melting Point
8–25 MPa 100–650% R45–R65 60–110 J/m 45–70°C 40–60°C 105-115°C

Advantages & Application of CNC LDPE Machining

LDPE CNC Parts Surface Treatment

LDPE is commonly used for CNC parts such as flexible housings, liners, protective covers, tubing supports, and lightweight structural components. It has excellent chemical resistance, flexibility, and impact resistance, but low surface energy makes coatings and paints difficult to adhere to.

Mechanical polishing or light tumbling can remove machining marks and smooth the surface. This improves tactile feel and reduces friction in sliding parts. Due to LDPE’s softness, polishing should be gentle to avoid deformation.

For parts requiring grip or non-slip surfaces, light sanding or mild sandblasting can create a textured finish. The intensity should be carefully controlled, as LDPE is soft and easily deformed.

For functional assembly, LDPE parts can be chemically or thermally welded. Solvent bonding is limited, but heat or ultrasonic welding is effective for joining flexible parts.

LDPE has limited thermal resistance. It is not recommended for high-temperature applications. For better heat performance, consider HDPE, PTFE, or PEEK.

Typical applications include packaging machinery components, protective liners, fluid system parts, low-friction guides, and chemical-handling equipment.

Yes, LDPE can sometimes be welded to HDPE, but it requires proper temperature control and technique due to different melting points and thermal behaviors.

Yes. Our team has experience machining LDPE with tight tolerances and complex geometries, optimizing designs for precision and durability.

Accurate pricing requires a CAD file or technical drawing. Rough estimates can be provided from sketches, but detailed files ensure precise quotes and faster production.
