Polymers with a lightly cross-linked molecular structure are called elastomers.
The molecular chains can move relative freely between the cross-links giving them an elastic behavior.
Elastomers are used for rubber bands, tires, springs, etc.
Typical elastomers are rubber, silicone and polyurethane.
The ability of an object to emit infrared radiation is called emission.
In the infrared temperature measurement, the temperature of the object is calculated based on the intensity of the emitted radiation.
The proportion on emission of the radiation collected by a infrared camera is described by the emissivity.
The radiation detected by a thermal camera in a non-contact temperature measurement consists of the reflection, the transmission and the emission of infrared radiation emanating from objects in the field of view of the camera. The emissivity is a dimensionless measure that indicates the ratio of the emitted radiation of the measurement object in relation to the incident radiation.
Emissivity depends on the material, the surface texture and, in some cases, the temperature of a body. In general, the higher the emissivity of a body, the easier the temperature can be measured with a IR-camera.
The following relationship applies: Emissivity + Reflection + Transmission = 1

An integrated software solution for managing and optimizing business processes in plastic processing is called Enterprise Resource Planning or short ERP-System. It enables the management of material procurement, production, inventory, order processing, and financial accounting within a central system. In the plastics industry, an ERP system helps monitor material consumption, efficiently plan machine capacities, and optimize production processes. By integrating with MES (Manufacturing Execution Systems), production data can be recorded and analyzed in real time. This improves batch traceability, reduces scrap, and increases production efficiency. Specialized ERP solutions for the plastics industry take into account factors such as recipe management, tool management, and raw material traceability. A well-implemented ERP system significantly contributes to efficiency improvement and cost reduction in plastic processing.
When manufacturing silicone parts by injection molding, removing air from the mold before injecting the material is a crucial step to ensure optimal product quality.
This process, known as mold evacuation, is used to avoid air bubbles and inclusions in the final product,
which could otherwise negatively affect the mechanical properties and aesthetic appearance.
By removing air from the mold cavity, the viscous silicone material can be evenly distributed and fill all areas of the mold.
This leads to increased accuracy of the component geometry and improved surface quality.
The use of this process is particularly important in silicone processing, as it ensures product consistency and significantly reduces the likelihood of production errors.
