Hard core technology

Two processing procedures are applied the soft core technology and the hard core technology . As the name implies, the two processes can be differentiated in the design and in the material of the core molds. 

In the hard core technology , mostly multi-part, hard cores made from aluminum are used as an attachment to the nonwoven component. The pressure onto the component occurs through heat expansion of the core during heating.

Following are described the physical properties of hard-core reverse micelles, the effect of changing the surfactant, the exchange solubilizates, and some specific aspects, e.g., technological relevance. To clarify this, the following five topics are considered ... 

It is unlikely that any revenue could be generated by landfill, since the non-me-tallic residue is voluminous, compressible, and lacks the properties desirable in hard-core. Current technology cannot profitably separate individual plastics from shredder residues to provide fractions which can be used in applications similar to the original use. It has been estimated that, in the period 1985-1990, only about 25% of the total quantity of plastics waste is likely to be diverted from the municipal waste stream and recycled. Of this, some 27%, i.e. approximately 7% of the total is likely to come fi om the transport sector in the United States. 

Thanks mainly to improved methods and advances in computer technology, but aided by hard work, persistence, adaptability, optimism, and patience, computational chemists became able to answer research questions better and faster. Computers became easier to use, quicker, and capable of handling larger molecules. One of the aspects that experimentalists had a particular trouble accepting was the need for computational chemists to use simplified models of the structures they computed. Computational chemists could readily understand that replacing computationally irrelevant side chains with hydrogens would have no material effect on the outcome of the calculations of, say, the electronic structure of the core of the molecule. However,... 

Natural and synthetic iron oxides not possessing pigment properties are used as raw materials in the production of hard and soft ferrites (see Section 5.5.5.2, Electro- and Magneto-Ceramics) for radio, television and telephone technology, for adhesive magnets, for rotors in dynamos, for low-loss magnetic layers, for DC-motors, for transformer cores, for electronic calculators and high frequency furnaces. This amounts to an annual worldwide production of more than 300 10 t/a. 

For each supply chain, the impact is different. There are no hard-and-fast rules. The trade-offs of customer service, forecast accuracy, and inventory are the easiest to understand. Through continuous improvement programs, employee training, investments in technology, and alignment of metrics, the core of the supply chain can be improved.
