Low Cost Packaging Machines
1999 Barsleaks is a small New Zealand company, operating in Australia. One of its products is an organic compound designed to be put into an engine's coolant in an emergency to seal leaks. Bars Leaks operated from a small factory at Caringbah in the South of Sydney. The filling of the Bars Leaks bottles was, at that time, done by hand. They asked NVTech to design and build a low cost pellet measuring machine and a machine that would screw on plastic bottle caps. The low cost pellet machine consisted of a sliding drawer of Ultra-high-molecular Weight Polyethylene driven by a pneumatic ram. Later it was found that the machine, because of its precision was saving them around a cubic metre of mix every three months. The capping machine was created using a cheap vertical drill driving a roller-skate wheel, fashioned on a lathe, to grip the caps.
