TECHNICAL NOTE
The Same Geometry May Require a Different Material
Two industrial parts with the same dimensions may require different materials because of differences in load and contact conditions. Material selection depends on the component’s function within the system as well as its geometry.
MATERIAL SELECTION
Selection Is Not Based on a Single Property
Friction behaviour, impact strength, dimensional stability, temperature and chemical contact are evaluated together. The engineering plastic grade or metal option is determined by these combined technical requirements.
In assemblies combining plastic and metal parts, mating surfaces, connections and installation dimensions are also considered. Selection is based on the system as a whole rather than a single material property.
TECHNICAL FRAMEWORK
Technical Factors Evaluated
01
Load and Motion
Load to be carried, type of motion, speed and operating cycle.
02
Wear and Contact
Friction, impact, mating surface and lubrication conditions.
03
Operating Environment
Temperature, moisture, chemical contact and outdoor exposure.
04
Installation and Supply
Installation method, tolerances, maintenance requirements and repeat-order expectations.
TECHNICAL REQUIREMENTS
Is the Part Material Undetermined?
Material and manufacturing options can be evaluated from a technical drawing, 3D file, sample or application information.
