Efficient Pressure Casting Technology

LAU Kotter die casting technology – made in Germany a little tricky is sometimes already, because the tasks of customers on their components are becoming increasingly complex. But that is just what sets us apart from domestic competitors and suppliers from abroad: we won’t stop until we can present our customers a qualitatively and economically portable solution for the production of aluminium or magnesium components “, grins CEO Michael Lai ward. An approach that is without a doubt. Because eventually it goes not only to the realization of an efficient pressure casting process, but also just about to meet the high demands on the component and its future use. The philosophy to provide customers with complete ready to install components, the company was boosted by the economic crisis and contributed to a healthy and continuous growth.

With just mid-20s took over Michael Lai ward of the company founded in 1971 in the 1990s and can today, with 42 Years, look back on a great business development. The turnover has become so within the last 10 years tripled and resulted in staff growth from 80 to 180 employees in the same period. Die-cast but when it comes to pour large production lots in consistently high quality with maximum precision and to realize filigree and difficult component shapes, falls the choice on the cast for the mass – with class. Not least because there is no comparably efficient manufacturing process based on the required number. With a force of approximately 300 to 1000 bar and form filling speeds of up to 120 m/s the aluminum or optional magnesium melt in the appropriate die casting mould pressed where she froze in the connection. The extraordinary advantage of die casting is the mold that is specially made for the respective product.

KSB Motors

KSB launches support program for building technology developed by KSB and SuPremE Motors produced meet the efficiency requirements of class IE4 when operating with the speed control unit PumpDrive (com. IEC(CD) 60034-30 ed. 2). They are now much better than it calls EU law for the year 2017. Now for the technical equipment of the building to make accessible this CO2-friendly technology the Frankenthaler pump producer KSB launches a special funding program. As of October 1, 2013 all speed-adjustable Inlinepumpen are delivered of type Etaline from 0.55 kW up to a performance, including 18.5 kW without extra charge compared with the previous IE2 solution with SuPremE motors. So operators save money immediately after the first commissioning and don’t have to worry about the payback period of the new technology.

Buy traditional high-efficiency motors”is the manufacturer high efficiency in the entire load range through the use of permanent magnets with high power density. From this arise significant disadvantages in the life cycle assessment of these products. Also yet no recycling process is defined so-called rare-earth magnetic materials based on. Magnet free synchronous – reluctance motors, such as the SuPremE motors, represent an economical and environmentally friendly alternative. The CO2 equivalent is a 7.5 kW motor with 16.550 kg significantly below an IE3 asynchronous motor (28.710 kg) and an IE4 permanent magnet motor with 17.560 kg for an operating time of a pump in the heating or cooling system by 15 years. No location detectors are required to operate of the new SuPremE motors. How to get to the same reliability as an asynchronous motor.

The life of the bearings is even slightly raised due to the low heat losses in the rotor. The dimensions are fully compatible to the asynchronous standard motor. The engines produced since March, 2012 in series have proven themselves in numerous industrial applications up to a rated power of 45kW.


Number – an abstract entity used to describe the amount. Sequence. There are different kinds of numbers. Natural numbers 1,2, used for counting objects. Set of natural numbers is denoted. If the natural numbers to add negative numbers and zero, we obtain integers.

Whole numbers in mathematics are studied within the framework of the theory of numbers. Relationships of integers are called rational numbers, or ordinary fractions. The set of all rational numbers is denoted. If by rational numbers add all the endless and non-recurring decimals are called irrational numbers, we get real numbers. Except unit on rational and irrational, real numbers are also classified into algebraic and transcendental. At the same time every transcendental number is irrational, every rational number – algebraic. Real numbers, in turn, can be extended to complex numbers. Complex numbers can be extended to quaternions, but multiplication of quaternions is noncommutative.

In turn, the octave are extensions of quaternions, are already losing the property of associativity. In mathematics, for the sets there is a set amount of power, a similar number of elements in it. The development of this submission for infinite sets led to a further generalization of the concept of number. Now talking about cardinal numbers, which describe the set of any number of elements – finite or infinite.
