PA6 - PA66

PA6 - PA66 molding is a widely used technology for producing technical plastic components that must ensure high mechanical performance, heat resistance and long-term durability. PA6 (polyamide 6) and PA66 (polyamide 66) are engineering polymers known for their strength, dimensional stability and ability to withstand heavy loads even in demanding environmental conditions.

Thanks to these characteristics, PA6 and PA66 are used across multiple industries, including automotive, mechanical, electrical, hydraulic, water treatment, orthopedics and industrial automation. Companies like Expyou, with advanced machinery and extensive expertise, transform these materials into precision, reliable and custom-made components.

Characteristics of PA6 and PA66 in injection molding

PA6 is slightly more flexible and impact-resistant, while PA66 offers greater rigidity and thermal resistance. Both variants share the following properties:

• High mechanical and tensile strength, even under prolonged load
• Excellent wear and impact resistance, ideal for components subject to friction or shock
• Dimensional stability, even under thermal variations
• Good chemical resistance, particularly to oils, fuels and solvents
• Self-lubricating properties, suitable for gears and moving parts

There are also glass fiber–reinforced or additive-modified versions that further enhance their performance.

How does PA6 - PA66 molding work?

PA6 - PA66 molding is performed through high-temperature injection with strict control of material humidity and process parameters. The granules are dried, melted and injected under high pressure into the mold. Once solidified, the component is ejected and can undergo finishing or assembly.

These materials require precision, expertise and specialized equipment to avoid deformation, shrinkage or moisture absorption issues. Expyou uses advanced machinery and computer-controlled systems to ensure flawless results in every production cycle.

Key advantages of PA6 - PA66 molding

PA6 - PA66 molding enables the production of high-performance components that combine strength and functionality:

• Excellent mechanical properties, ideal for structural applications or continuous stress
• High thermal resistance, with operating temperatures above those of other engineering plastics
• Long operational life, even in harsh industrial environments
• Good processability and dimensional precision, suitable for complex shapes and technical assemblies
• Versatility across industries, with customization options and reinforced variants available
