Plastic chains are the best choice for 3D printers and CNC machines. For increased durability, heat insulation, or industrial applications, chains made from plastic rods and aluminum offer greater strength.
Plastic drag chain (for classic use): Ideal for modern devices such as 3D printers, small CNC machines, or electronic equipment.
15x30mm drag chain: Easy to install, quiet, easily extendable or shortened, low heat insulation to prevent corrosion, stable and smooth performance, but may be damaged by heavy use or weight, and may not be suitable for industrial environments.
25x25mm plastic drag chain: Easy to install and secure to devices, provides good cable protection, and is flexible enough for Android devices and printing.
But it's never too late, and plastics may evolve over time.
Plastic and aluminum bar drag chain (durable) for: industrial equipment, lifting tools, program production lines, and other applications requiring high strength and durability.
Aluminum bar cable chain: Stronger than plastic-only chains, as the aluminum bar provides added rigidity to the cover. It also offers better fire and corrosion resistance than classic plastic chains, but is heavier than iron-only options. Its greater strength may make installation or adjustment more difficult.
Plastic chain with aluminum bar cover: The aluminum bar cover provides high strength for cables and hoses and can withstand high speeds and loads, but is less stable than plastic-only chains.
