When sourcing tufting guns, you must distinguish between Cut Pile and Loop Pile models, or opt for 2-in-1 versatile machines. Key technical factors include the adjustable pile height (typically 7-21mm for cut pile), motor speed (ranging from 2400 to 3000 RPM), and voltage compatibility (ensure the supplier provides 110V-240V universal adapters). For industrial durability, prioritize models with integrated gear protection covers and high-grade aluminum alloy bodies to ensure heat dissipation during prolonged operation.
