Kit Assembly and Custom Packaging

Bulldog® maintains facilities specifically designed for the assembly of components into kits and other forms of custom packaging. Extensive capabilities have been developed to support the process of kit manufacturing and assembly. Customer requested kits can be easily documented and integrated into our kit assembly process. Custom packaging capabilities include the ability to apply part numbers to items, bags, and boxes. In addition, items can be boxed or placed on flat sheets (for example, corrugated sheets) for the application of labels and shrink-wrapping. These Bulldog® kit and packaging capabilities can offer substantial advantages to customers by providing them with pre-assembled kits for service and repair needs. Pre-assembled kits, when compared to individual components, can provide overall reductions in total product costs by reducing purchasing, receiving, quality control, and warehousing activities. In addition, pre-assembled kits can increase customer serviceability and satisfaction.
