A huge relief in the running-in process

If there is a line on the bottom of the bottle instead of a central injection point, then the plastic bottle was manufactured using the extrusion blow molding process; explained in very basic terms. In this case, it is quite possible that the product was manufactured on a machine from new HESTA.

Depending on the size of the system, the functional handle directly on the safety door
can save up to 3 meters of travel each time it is used to unlock and lock the door.

With Swabian attention to detail, the 20-strong team has been developing innovative solutions in the field of extrusion blow molding technology for many years. All systems already impress with a high degree of automation, low personnel requirements, and quick setup – the changeover of tools and products – but there is always room for optimization in the details.  

One item on the designers' wish list was a way to make life even easier for machine operators during the run-in process. During this process, the sensor-secured safety door has to be opened many times, as it can only operate in accordance with CE standards when closed. The impulse to unlock or lock is triggered by a button on the HMI. For 20 years, all new HESTA systems have been available on the market in a fully electric version with convenient PLC control and a touch panel. However, depending on the size of the system, the distance to this button can be up to three meters.

The goal was therefore to make it possible to unlock the machine safety door easily and on site. A robust handle was needed that clearly indicated the status of the machine and immediately authorized the door to be opened. This is where KAtech Automatisierung from Filderstadt came into play. With over 35 years of expertise in the industry, it has been an established partner for the electrical control of blow molding machines for many years.

“Technically speaking, it's exactly what we were looking for, but we also really like the shape of the functional handle, which integrates beautifully into the new machine design,”

confirms Christian Braun, Managing Director at KAtech.

 

He became aware of the aluminum handles with the extra-long light bar during a conversation with Johann Roshau, Area Sales Manager at Kraus & Naimer. The choice fell quite quickly on the FH04-LL. It is strongly rounded at the back and fits particularly well in the hand, while the handle arms made of glass ball-reinforced polyamide PA 6 easily withstand frequent tensile loads. The long illuminated plastic insert made of translucent PMMA in the handle bar clearly indicates the status of the system, even from a distance. The safety door can be conveniently unlocked or locked with the thumb using the recessed push button. 

Simplified setup, faster start of production, optimization successful! ✔
