The Dr.-Ing. K. Busch GmbH of Maulburg, Germany, has consistently further developed its Mink MV dry claw vacuum pumps (Fig.). Based on the already proven Mink MM series, which belong to the proven standard when it comes to creating vacuums, they have, compared to similar systems on the market, succeeded in reducing the noise level by using a newly developed silencer. At the same time, the manufacturer boasts of the units’ compact construction and high efficiency. As with their previous series, this current MV series works according to the dry and non-contacting claw principle. Maintenance work, such as oil or filter changes, is eliminated, since no operating fluids are required in the pumping chamber. Moreover, the non-contacting design eliminates wear.

Improved Vacuum Pumps for Feeding Materials 

The vacuum needed for conveying bulk material can be generated with side channel blowers, but it is much more energy-efficient to use vacuum pumps. These can slash the power consumption needed for vacuum generation by up to 70 %.

The bonding of individual thermoformed parts requires high precision. The vacuum experts at Busch rely on a claw vacuum pump without lubricants to produce housings in medical technology. The frequency-controlled system adapts its performance to the respective requirements.

By using a vacuum, powder or granular materials can be transported without any problems. Depending on the application, different vacuum pumps for pneumatic suction conveying can be considered. The decisive factors here include the length of the conveying distance, the type of conveying and the required differential pressures.

Comprehensive resource efficiency means far more than the preservation of natural resources. It also includes the productivity factors of material, machine and labor. The plastics industry has made a great contribution to resource efficiency, but often finds itself on the defensive. Yet a knowledge of the various relationships involved provides enough material to go on the offensive with arguments illustrating the benefits of plastics technology.

Resource Efficiency with  Plastics Technology 

Rotation, shear, heat and pressure – this much is clear: These are the factors required to compound plastics on twin screw extruders. From a scientific point of view, however, the question remained until recently as to which mechanisms exist during incipient fusion along with the energy input into the melt resulting. Scientists from the plastics division at Fraunhofer Institute for Structural Durability and System Reliability LBF in Darmstadt, Germany, have been successful in gaining an insight into these processes by using new types of measuring techniques.

New vacuum solution ensures safe and sustainable tires at Continental

In its tire manufacturing process, Continental uses central vacuum supply from Busch Vacuum Solutions. In addition to significantly reducing noise in the production room, this vacuum solution also leads to a high level of savings when it comes to the tire manufacturer’s energy and maintenance costs.

Nearly every third vehicle in Europe drives on tires made by Continental, which mixes the natural rubber raw material itself, then extrudes it and, after several intermediate steps, processes it into ready-to-mount tires. A single tire consists essentially of three main components: textile cord, steel wire and a natural rubber mixture. These three basic materials are combined in a specific way in the individual components of the tire, then assembled as carcass and belt, formed into a tire and hardened.

The textile cord consists of a large number of textile threads and is inserted into a calender using a large uncoil device. This is where the textile cord is coated with natural rubber, and a rubberized web is created in the form of a continuous long strip that is less than one millimeter thick. This web is cut to the desired width perpendicular to the thread pattern and rolled into a textile roll again for further processing. The textile material is later directly attached to the innermost layer of rubber. It functions as a reinforcing element on the inside of the tire. The radial orientation of the threads ensures additional stability. This layer primarily influences the carrying capacity of the tire as well as the suspension behavior and handling characteristics.

Previous Vacuum Supply Consumed Enormous Amount of Energy

Vacuum technology is used for handling tasks at the textile cutting machine. The rubberized web is cut to the desired length and then directly applied to another strip using pick-and-place. Here, precise positioning is the most critical aspect when it comes to the quality of the finished textile web. The individual layers need to lay exactly on top of one another. One side channel blower used to be installed in each of three textile cutting machines.

These provided the necessary vacuum for handling the strips of textile. The blowers ran constantly at full power and thus consumed enormous amounts of energy. In addition, they created significant noise pollution for the production staff.

An employee from Continental Reifen suggested via the internal Idea Management that someone should take a closer look at the vacuum supply of the textile cutting machines. Their primary concern was the acute noise pollution due to the previously used side channel blowers. Because Continental is always searching for potential ways to improve, they decided to look for a more ergonomic and efficient solution. The vacuum experts at Busch Vacuum Solutions recommended using a Mink claw vacuum pump to generate vacuum and initially provided a test system. It only took a couple of days for Ingmar Heinze, Head of Utilities and Sustainable Infrastructure, to become convinced that he had found the right solution for generating vacuum.

After the test run, a vacuum system with two Mink MV Synchro vacuum pumps was installed at Continental. This system replaced the previous three side channel blowers and now centrally supplies the necessary vacuum for several textile cutting machines via stainless steel pipes. Mink MV Synchro vacuum pumps are fitted with a frequency converter and demand-driven control unit as standard. The vacuum pumps detect the pumping speed they need to provide in an ongoing process to securely hold the rubberized textile cord and precisely place it.
