Material Selection Guide
The selected plastic affects machining strategy, tolerance control, surface quality, and application performance.
Engineering plastics are not interchangeable. Each material has different behavior during machining and different limits in temperature, chemical exposure, dimensional stability, optical clarity, wear, and mechanical loading.
Mechanical Properties
Strength, stiffness, wear behavior, and impact resistance influence part performance.
Temperature Resistance
Thermal stability affects material choice for equipment, fixtures, and process parts.
Chemical Resistance
Material compatibility should be reviewed for solvents, reagents, and cleaning conditions.
Dimensional Stability
Moisture, stress, thermal expansion, and geometry affect long-term accuracy.
Optical Performance
Transparent applications require attention to PMMA, PC, surface finish, and polishing needs.
Machining Feasibility
Feature size, wall thickness, tolerances, and burr control should be checked before production.
