Safe and sustainable packaging with Weber wePACK 7000

In 2019 Weber presented their first in-house developed and manufactured thermoforming packaging machine, which convinced through very high output and quality, as well as ease of maintenance and service: the wePACK 7000.

Safe and sustainable packaging with Weber wePACK 7000

This thermoformer "Made in Germany" has customers excited worldwide and is now available in a further advanced version packed with a variety of innovative and clever details. At first glance, it is obvious that the generally high quality standards that Weber stands for also played in to the development of the wePACK and will ensure a long service life.

This thermoformer has the most robust stainless steel frame currently on the market, which brings numerous advantages with it when it comes to the harsh production conditions. The wePack easily absorbes even rough bumps thanks to the compensation of the main weight forces in the bottom frame longitudinal member which ensures an acuratehorizontal film run.

Quick, strong, precise: made from 100% stainless steel

Process reliability and energy efficiency thanks to servo technology.

One of the impressive highlights of the Weber thermoforming packaging machine is revealed inside the machine. It is the tool stroke with servo drive which has been particularly developed to meet the requirements of the food industry. In addition to the high energy-efficiency, the servo-driven stroke offers optimized process times - even with different packing depths. Quick, strong, precise: made from 100% stainless steel, the tool stroke sets new standards featuring Weber's standard hygienic design at unmatched speed for maximum output. The stainless steel design gives the stroke high rigidity and thus enables long service life without the need for maintenance, even at heavyusage. Due to the smart design, it does not require lubrication. This provides ideal conditions for cleaning and reduces downtimes for maintenance. Weber's use of servo-drives for the wePACK 7000 cross-cutters reduces the running operating costs through energy efficiency and higher output. The servo-drive technology enables the control of the entire cycle sequence which ensures absolute process reliability. In addition, the cross punches run slower in closed-loop operation at start and end cycles in order to minimize wear.

Integrated top film printing with weMARK movement unit

With weMARK, the Weber thermoforming packaging machine features another technical innovation - the fastest transfer unit for continuous ink jet print heads on the market. The integrated x/y movement unit can be used for all conventional ink jet printers on the market for printing on the top film. In doing so, the display of the printer control panel can be mirrored conveniently onto the WPC which facilitates ergonomic operation without long walking distances as well as the complete operation and print management from a single display. Naturally the new Weber x/y transfer unit comes with a standardized "no product, no print" function in order to reduce running costs. In case the print head has to be replaced, weMARK also permits bi-directional printing. In practice, food processing companies benefit by reducing process-related waiting times and a maximizing output. The new quick-change system of the roller shear cut is another impressive innovation. It takes maximum five minutes to change the bottom knife and only about one minute to change the top blade shaft - no other slicing system on the market has a quicker or easier change. The system guarantees a high level of work safety thanks to exchangeable cassettes with pre-assembled blades and the simple and easy execution - even for trained personnel. Thanks to the automatic adjustmentto the ideal contact pressure, downtimes are reduced and time-consuming readjustment are a thing of the past.

It is the wide array of clever technical innovations of the wePACK that enables production of food processing companies to be more economical. Thanks to a camera-supported check of the actually stretched upper film roll against the stored recipe data, film and product losses are avoided. Moreover, the camera inspection contributes to a significant increase in production reliability. The new web edge control of the bottom film unwind not only reduces complexity thanks to a simple mechanical design, but is also able to correct web run deviations smoothly and accurately with the help of a tendency detection of lane position deviations. Space-saving, cost-effective, application-safe: the upper die of the Weber thermoforming packaging machine is now equipped with an integrated gate for peel corners - andwith a quick-change insert to reduce downtimes when changing formats.
