HDPE

HDPE in CNC Machining and Injection Molding

High-Density Polyethylene (HDPE) is an affordable, versatile, non-porous thermoplastic with a high strength-to-density ratio and low moisture absorption.

HDPE is made from the ethylene monomer and is also called “alkathene” or “polythene.” It has a low melting point but high impact strength, chemical resistance, and excellent electrical insulating properties. Because this material can deform under heat, we are very careful when machining thin-walled sections. We use appropriate cutting speeds and feeds, tools with sharp cutting edges, water-soluble coolants, and proper cutting techniques for the best results.

Engineered as industrial-grade, FDA, NSF, and USDA-approved food-quality material, HDPE sheets are designed to be low maintenance, safe, and durable. The textured surface provides a secure grip for handling food safely. Aside from being easily meltable and moldable, it is corrosion, chemical, and weather-resistant. Additionally, HDPE is an environmentally friendly choice because it is cost-effective and recyclable.

Basic Knowledge of HDPE

High-density polyethylene (HDPE) is a strong and durable type of polyethylene, a thermoplastic polymer with high strength, chemical resistance, and versatility. It is plastic made from petroleum with the chemical formula (C2H4)n. With a high density, it exhibits toughness and can withstand impact and abrasion. Because of its resistance to moisture and chemicals, HDPE is commonly used to produce containers for liquids, such as bottles for milk and detergent. It is also used to construct water supply and drainage pipes due to its lightweight nature, durability, and corrosion resistance. Additionally, HDPE is used in geomembranes for environmental purposes, construction materials, and recyclable products.
