This is a huge disadvantage for companies competing in the global automotive industry that underlies strict cost pressure. Ideally, all of these four factors should be able to be managed in order to avoid scrap production. Thermal analysis methods offer a valued approach to evade costs.
Early-warning analytics for potential failures: Control your incoming material
One approach to reduce scrap production resulting from material-related problems can be to control the incoming material. This can then ensure that the properties of the material are correct and that there is no deviation from the specifications agreed upon. Differential scanning calorimetry determines physical transformations, e.g., Phase TransitionsThe term phase transition (or phase change) is most commonly used to describe transitions between the solid, liquid and gaseous states.phase transitions such as Glass Transition TemperatureThe glass transition is one of the most important properties of amorphous and semi-crystalline materials, e.g., inorganic glasses, amorphous metals, polymers, pharmaceuticals and food ingredients, etc., and describes the temperature region where the mechanical properties of the materials change from hard and brittle to more soft, deformable or rubbery.glass transition temperatures, melting peaks, CrystallizationCrystallization is the physical process of hardening during the formation and growth of crystals. During this process, heat of crystallization is released.crystallization temperature. Read more on the method here! An application example for the reduction of scrap could be: Once the material for a thermoplastic part or component has been selected, the required specification as well as a fixed deviation from the ideal material are determined. New material that is delivered to the company is then analyzed to see if the material adheres to the defined range of property variations. This comparative and proactive analysis is efficiently done with the right software features. Learn how to integrate the Proteus® software features into your incoming goods inspection!
Optimizing reactive injection molding with in-line sensors
Injection molding with thermoplastic materials has been done for many decades. Thermosets open a new chapter of high-performance parts regarding their mechanical strength. However, producing parts from thermosets is tied to a lot of influences on the production process. For instance:
- changes in the material behavior due to different transportation environments,
- storage on the customer’s site,
- machine failures like pressure loss,
- temperature deviations inside the mold between the first and the last component of one batch or due to defects in the heating of the mold.
To overcome these hurdles and to produce good parts, there is a huge amount of safety time during manufacturing. As a result, the full potential of manufacturing processes can often not be fully exploited. NETZSCH and KISTLER partnered up to advance production to a level that allows robust manufacturing while enabling a maximum in cycle time reduction at the same time.
