Machine Image	Benefits
	High-Precision Screw Weighing The 10-head screw weigher delivers fast and accurate weight dosing for mixed or single-spec screws, significantly reducing giveaway and maintaining stable output even with small, heavy metal components.
	Robust Vertical Packaging Design for Hardware The LD-420Y features a reinforced film pulling system and strong sealing jaws designed specifically to handle dense, abrasive items like screws, minimizing film tearing and ensuring long, clean seal lines.
	Inline Labeling for Ready-to-Ship Packs The bucket-less skirt-belt conveyor lifts screws steadily without jamming or rolling back, keeping the flow controlled and preventing damage to the hardware or feeding system.
	Anti-Wear Contact Surfaces & Dust Management This is the final step in the four-sided sealing, providing the bag flat edges as well as solid protection. It enhances freshness, blocks moisture or air from entering the bag.
	Flexible Bag Formats for Hardware Kits Capable of forming various bag types—such as pillow bags, gusset bags, or back-seal pouches—to support different screw assortments, kit packaging, or OEM/retail requirements.
