Definitions

  • the present invention relates to a method for the production of hollow molded articles, to an apparatus for the production of hollow molded articles and to the use of a device according to the invention for the production of molded articles.
  • Moldings are usually produced by embossing in the upper side of a bulky shaped body, usually a tablet, a trough, which can be filled in a subsequent confectioning with another material, in particular, poured out.
  • Molded articles are produced, in particular, from substances which become active in combination with other substances. Frequently, the situation is given that the different substances then unfold their effect most advantageous when they go in a well-defined sequence during the application in solution in order to work together in dissolved form.
  • a common field of application for this type of agent addition is machine dishwashing.
  • the quantities added to the machine capacity are pressed into shaped bodies, in particular tablets.
  • Powdery or granular active ingredients which are to be added separately because of the above-described more effective effect unfolding, are pressed together in discrete layers on top of each other.
  • the combination drugs are originally in pasty or liquid, for example molten form, which is unsuitable for compression, the indentation of a trough in the molding surface is a proven form for the design of all desired substances of a combination of active agent receiving shaped body. In this trough, the liquid, molten and / or pasty active agent can be entered and solidify therein after filling.
  • the present invention is therefore based on the object to provide a method for the production of hollow moldings, which avoids the overpressing of portions of the Muldenform stressess.
  • the embossing element usually consists essentially of a hard and durable durable material. Corresponding materials are known to the person skilled in the art and can be selected as a function of the material to be compacted.
  • the embossing element made of metal, in particular steel; made of ceramic materials; or in a preferred embodiment of the invention consist of a hard plastic.
  • plastics in the context of the present invention characterizes materials whose essential constituents consist of such macromolecular organic compounds which are formed synthetically or by modification of natural products. In many cases they are meltable and malleable under certain conditions (heat and pressure). Plastics are therefore in principle organic polymers and can be classified according to their physical properties (thermoplastics, thermosets and elastomers), the nature of the reaction of their preparation (polymers, polycondensates and polyadducts) or their chemical nature (polyolefins, polyesters, polyamides, polyurethanes, etc.).
  • Hard plastics in particular meet the requirement profile that the embossing element at the same time be hard and resistant to high surface loads, but on the other hand should also have friction-reducing or lubricating properties.
  • hardness is in the context of the present invention, the term for the resistance that opposes a solid body to the penetration of another body.
  • a common dynamic method of hardness determination is the return method.
  • the Shore hardness determined in this way is determined in the case of steel by the ball impact test as rebound hardness or, in the case of rubber and other elastomers, as a penetration resistance against a truncated cone.
  • harder plastics e.g. for hard thermoplastics and especially for thermosets
  • the ball hardness is measured as the quotient of the test load and the surface of the impression of a steel ball (5 mm diameter) after 10, 30 or 60 seconds under load.
  • Polyolefins preferably polyethylene or polypropylene, have proved to be particularly suitable as plastic materials for the embossing element.
  • Polyethylene (PE) are polymers belonging to the polyolefins with groupings of the type - [CH 2 -CH 2 ] - as a characteristic basic unit of the polymer chain.
  • Polyethylenes are made by polymerizing ethylene according to two fundamentally different methods, the high pressure and the low pressure process. The resulting products are accordingly often referred to as high pressure polyethylene and low pressure polyethylene, respectively; they differ mainly in their degree of branching and, consequently, in their degree of crystallinity and their density. Both methods can be used as solution polymerization, Emulsion polymerization or gas phase polymerization.
  • the high pressure process produces branched low density polyethylenes (about 0.915-0.935 g / cc) and degrees of crystallinity of about 40-50%, referred to as LDPE types.
  • LDPE types branched low density polyethylenes (about 0.915-0.935 g / cc) and degrees of crystallinity of about 40-50%, referred to as LDPE types.
  • HMW-LDPE high molecular weight.
  • LLD-PE linear low density polyethylene
  • the macromolecules of the polyethylenes from low-pressure process are largely linear and unbranched.
  • These polyethylenes (HDPE) have degrees of crystallinity of 60-80% and a density of about 0.94-0.965 g / cm3. They are particularly suitable as stamping element materials.
  • Polypropylene (PP) are thermoplastic polymers of propylene with repeat units of the type - [CH (CH 3 ) -CH 2 ] -
  • Polypropylenes can be prepared by stereospecific polymerization of propylene in the gas phase or in suspension to give highly crystalline isotactic or less crystalline syndiotactic or amorphous atactic polypropylenes, respectively. Of particular technical importance is the isotactic polypropylene, in which all methyl groups are located on one side of the polymer chain. Polypropylene is characterized by high hardness, resilience, stiffness and heat resistance and is thus a suitable embossing element material in the context of the present invention. An improvement in the mechanical properties of the polypropylenes is achieved by reinforcement with talc, chalk, wood flour or glass fibers, and also the application of metallic coatings is possible.
  • polyamides in the context of the present invention are preferably insertable embossing element materials.
  • Polyamides are high molecular compounds that consist of blocks linked by peptide bonds.
  • Polyamides (PA) are, with a few exceptions, thermoplastic, chain-like polymers with recurring acid amide groups in the main chain. According to the chemical structure, the so-called homopolyamides can be divided into two groups: the aminocarboxylic acid types (AS) and the diamine-dicarboxylic acid types (AA-SS); where A is amino groups and S is carboxy groups.
  • the former are formed from one building block by polycondensation (amino acid) or polymerization ( ⁇ -lactam), the latter from two building blocks by polycondensation (diamine and dicarboxylic acid).
  • the polyamides are coded from unbranched aliphatic building blocks according to the number of carbon atoms.
  • PA 6 is the polyamide composed of ⁇ -aminocaproic acid or ⁇ -caprolactam
  • PA 12 is a poly ( ⁇ -laurolactam) from ⁇ -laurolactam.
  • PA 66 polyhexamethylene adipamide
  • PA 610 polyhexamethylene sebacinamide
  • PA 612 polyhexamethylenedodecanamide
  • the polyamide types mentioned are preferred materials for the embossing element in the context of the present invention.
  • Polyurethanes are polymers (polyadducts) which can be obtained by polyaddition from dihydric and higher alcohols and isocyanates with groupings of the type - [CO-NH-R 2 -NH-CO-OR 1 -O] - as characteristic basic units of the basic macromolecules, in which R 1 stands for a low molecular weight or polymeric diol residue and R 2 stands for an aliphatic or aromatic group.
