Mold Concept Boosts Efficiency in Production of Pen and Auto-Injector Components

With Z.SONIC turn, Zahoransky’s mold concept claims to significantly accelerate the large-scale production of housings for pen and auto injectors while also making it more energy- and space-efficient. Against the backdrop of dynamically growing demand for such injectors, Z.SONIC turn offers manufacturers an effective possibility to make the best possible use of their production capacities. Depending on the application, the solution enables cycle times to be reduced by up to 30%, increases output by around a third, and reduces manufacturing costs per part by 20%. Sample ROI calculations also show that the investment can be amortized after approximately nine months, which is significantly faster than with conventional molds. 

At the heart of Z.SONIC turn is an advanced indexing technology that shifts part of the residual cooling away from the mold and makes part removal cycle-neutral. While the mold remains closed, an integrated rotary unit takes over the positioning for removal. At the same time, the next shot is already starting. The compact design also reduces the mass of the mold by around 1,000 kilograms compared to conventional solutions, shortening heating times, reducing the energy required and simplifying the design, as complex relative movements are no longer necessary.
