SBF1000V₄Balloon Former and Tube Necker integrates the function of tube necking and balloon forming.It uses hot air heating and cold air cooling,eliminating the bulky and expensive water jacket.The machine features our patent pending high-efficiency and high stability fan driven heating nozzles.Paired heating/cooling nozzles make temperature around the mold uniform.It adopts the same three section mold design commonly used with other type of balloon forming machines,with the difference that the mold does not have to be embedded in the water jacket.Instead,it can be mounted and removed from the mold clamps freely and with ease.Due to its flexible clamping system design,the SBF1000V4 can blow balloons up to 400mm long and more than 25mm in diameter without having to purchase any additional fixtures other than making the mold.These advanced design and technologies made the SBF1000V4 not only highly efficient,but also exceptionally affordable.
