It delivers a weighing range of 10–2000g (KB-A10) or 10–3000g (KB-A14) at speeds up to 65 PPM and 120 PPM respectively, with X(0.5) accuracy class and step motor drive for consistent, repeatable results. Ideal for hardware packaging lines integrating VFFS (vertical form fill seal) machines, pre-made pouch packaging machines, and automatic hardware bagging systems.\u003c\/p\u003e\n\u003ch2\u003eProduct Overview\u003c\/h2\u003e\n\u003cp\u003eThe Keypack Intelligent (kunbupack) KB-A Series is a purpose-built automatic multihead weigher for fasteners and small hardware components, designed to integrate seamlessly with VFFS packaging machines, pre-made bag packaging machines, and fully automatic hardware bagging lines. Whether you are packaging screws, bolts, nuts, rivets, anchors, washers, or mixed hardware assortments, the KB-A Series delivers high-precision hardware weighing with minimal giveaway and maximum throughput.\u003c\/p\u003e\n\u003cp\u003eBuilt around a custom-designed high-precision load cell with exceptional shock resistance, the KB-A10 and KB-A14 handle the irregular shapes, mixed densities, and abrasive surfaces typical of metal parts and fasteners — conditions that challenge standard combination scales. The reinforced center body structure and heavy-duty linear feeders ensure stable, uniform material flow even with high-density metal components, making this the ideal hardware weighing machine for demanding production environments.\u003c\/p\u003e\n\u003cp\u003eWith 100 preset parameter groups, multilingual interface, and automatic shortage pause, the KB-A Series supports multi-SKU hardware packaging operations and global deployment. Both models are compatible with downstream VFFS baggers, pre-made pouch machines, and automatic hardware bagging machines via timing hopper synchronization.\u003c\/p\u003e\n\u003ch2\u003eKey Features and Machine Characteristics\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eHigh-Precision Custom Load Cell for Metal Parts:\u003c\/strong\u003e Specially designed sensor with superior shock resistance and long service life — built to withstand the impact loads generated by heavy fasteners, bolts, and metal components during high-speed weighing cycles.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eVFFS \u0026amp;
