Test specimen made of smallest amounts of material
Micro test specimen
Are you in the development phase of a new material and want to test it quickly and efficiently? With injection-molded micro test specimens, even small quantities of plastic can be tested under very precise process specifications. For material development and generally for the development of microtechnical solutions, the production of micro test specimens offers a variety of advantages
- A wide variety of test specimens with different geometries can be produced from less than 50 g of material.
- Very cost-intensive materials can be investigated efficiently and cost-effectively.
- Materials from a laboratory production can be comparatively examined in the accredited test laboratory
- Recommendations for injection molding technology can be efficiently and quickly derived as early as the test specimen production stage.
- Various service properties, chemical resistance, bondability, etc. can be assessed.
The "formicaPlast" micro injection molding machine developed at the KUZ allows the processing of extremely small shot weights, even for materials that are sensitive to dwell time. Injection molding tools and test fixtures for a wide variety of test specimen geometries are already available for characterizing a wide variety of material properties.
Characterization of the injection molded material
The following test methods, for example, are available for selection:
- Differential scanning calorimetry(DSC) to evaluate the melting behavior and determine the glass transition temperature
- Thermomechanical analysis (TMA) to determine the linear thermal expansion coefficient
- Dynamic mechanical analysis(DMA) for analyzing the mechanical behavior under defined dynamic loads
- Determination of microhardness on injection molded micro test panels at room temperature
- Tensile test on micro test specimens 1/12 to determine mechanical properties (because of scaling effects only comparable with each other)
available test specimen geometries (micro test specimens in the KUZ molded parts catalog starting on page 16)
The range of materials that can be processed includes:
- Thermoplastics, including high-temperature materials and bioresorbable materials
- Solid and liquid silicones
In addition, many experimental materials are possible, which can be processed in a variety of forms (e.g. as granules, powders or flakes).
- Plasticizing and injection molding tests with small development batches (<50 gr).
- Investigation of the suitability of the material for injection molding
- Production of micro test specimens (available test specimen geometries in the molded parts catalogstarting on page 16)
- Material characterization in accredited test laboratory

Plastics selection in product development
Plastics are highly interesting materials with further increased potential for product development. A multitude of requirements to which the product is subjected in the application must be reconciled with the most efficient processability possible and a limited cost budget for the material. This seminar explains some basic tools for solving this complex problem. The content of the seminar is to underline the practical approach from the material selection to the real use of the product. Using a housing made of semi-crystalline material with/without filler and a lens made of amorphous material, the seminar content will be taught in a practical way.

Polymer analysis is still very important in the laboratory world. In this seminar, you will be introduced to two essential methods in detail: solution viscosity and contact angle measurement. Both cover relevant material properties and you will have the opportunity to have these techniques explained in theory and practice. The seminar is held in cooperation with LAUDA Scientific. You will be introduced to capillary viscometry for the determination of molecular parameters by means of the determination of the viscosity number, the IV-value and the K-value. In addition, you will be familiarized with the technique of contact angle measurement, and selected analytical methods will be presented. The emphasis is on very practical demonstrations of both techniques. Measurement series for automated dilution viscosity as well as gravimetric sample preparation will be examined and typical sources of error in everyday laboratory work will be pointed out. The Kunststoff-Zentrum Leipzig will provide an insight into the analytical methods used there.

Dimensional accuracy of molded parts
The special structure of plastics, which results from their molecular structure and essentially determines their properties, gives rise to some special features for the dimensioning and tolerancing of plastic parts compared to other construction materials. If these are not taken into account in molded part and tool design, this inevitably leads to disputes between plastics processors, toolmakers and OEMs. Get fit and use the plastics technology know-how of the new standard for effective project processing!

Micro injection molding
The development of plastic micro-molded parts is one of the more demanding operations in the field of injection molding of polymer materials. The demands on the production processes increase to the same extent, because small dimensions mean the highest precision. We will give you a practical introduction to the subject and an overview of the possibilities and limitations of micro injection molding.
