An accurate design leads to excellent results, the search for effective solutions and the use of high quality components make our machines efficient and reliable.




they are not subject to wear even when using CHROMATECH stainless steel profiles. The new Omron operator panels are equipped with a tactile display for simple and intuitive operational use, the realistic and captivating graphic setting makes them extremely functional. With the degree of protection IP65 they are perfectly suitable for use in harsh industrial environments. The K700 Hi-Tech Butyler comes standard with the automatic shutdown function of the motors after 4 minutes of inactivity, this allows to significantly reduce the consumption of electricity and ensure a long life of the components.

The K700 HI-TECH Butyl Machine is equipped with a particular proportional hydraulic valve that allows you to extrude with extreme precision, on both sides of the groove, always the same amount of butyl even by varying the speed of the conveyor belt. The rod holders, the pneumatic gripper and the butylating phases are synchronized with the working speed and do not require adjustments. The operator can in any case set the amount of extruded butyl (g. X ml.) And modify the start and end of the butylation on the groove, simply by acting on the Touch-Screen. The extruders built in steel are hardened and chromed
