Sanderson Machine Tools is the machinery manufacturing division of Sanpro Industries Ltd. Based in Wellington, New Zealand. We have been involved in the exhaust muffler manufacturing industry for almost thirty years and in that time we have come to understand the ever increasing pressure on manufacturers to become more efficient if they are to remain competitive. Each of our machines have been developed with this in mind. Sanderson Machine tools released the first Tube Louvre Machine to the United States in 1995. Their success has been such that Sanderson Machines can now be found in major manufacturing plants across the United States, Europe and around the world.
