PE

Polyethylene (PE) finds its optimal application in prototypes injection molding due to the fact that it is highly resistant to chemicals, easy to process, and cost-effective. Its impact strength and flexibility render it suitable for the production of containers, protective covers, and light structural components. PE in prototyping has widespread uses in the production of disposable products, packaging material, and water-sealed enclosures. Its quick processing and good dimensional stability allow rapid iterations. The simplicity and versatility of PE enable the achievement of complex designs, and it is a good material for early development.

PA

Nylon (PA) is a tough, impact, abrasion-resistant injection molding engineering plastic. Nylon is ideally used for functional prototypes with high mechanical properties, e.g., gears, bearings, and moving parts. High durability and low friction of Nylon allow prototypes to accurately represent actual operating conditions in the field with good repeatability. Its better resistance to repetitive stress and temperature fluctuation makes it the ideal choice for dynamic applications, and its ability to precisely generate intricate geometries makes it extremely detail-intensive in use.
