Technical Engineering with High-Density Polyethylene

HDPE is selected for its superior chemical resistance, low coefficient of friction, high impact resistance, and negligible moisture absorption. We match your part specifications with the correct forming or cutting process to optimize unit cost and structural performance.

01

Prototypes & Precision Parts

3-axis and 4-axis CNC milling and turning for wear strips, guide rails, bushings, manifolds, and structural brackets without tooling investments.

02

Hollow Components & Tanks

Extrusion blow molding and rotational molding for fluid reservoirs, chemical tanks, ducting, and buoyant enclosures with uniform wall thickness.

03

Medium to High-Volume Runs

Custom injection tooling and profile extrusion lines for continuous profiles, caps, technical fittings, and industrial housings with consistent repeatability.
