Delrin sheets possess excellent mechanical strength, dimensional stability, and machinability, making them an ideal engineering plastic for precision parts. Delrin is widely used in industrial machinery, including food processing equipment, as a cost-effective alternative to metal, providing consistent performance under heavy use.
Stock Shapes and Sizes
Delrin materials are available in a wide variety of standard and custom sizes to meet project requirements.
- Sheet thicknesses typically range from 0.5 mm to 100 mm.
- Standard widths: 500 mm, 1000 mm, or 1200 mm
- Standard lengths: 1000 mm, 2000 mm, or 3000 mm
- Bespoke dimensional capabilities: cut-to-size service on CNC machining or injection molding.
These sizing options allow manufacturers to create parts with minimal material waste and maximum precision.
Manufacturing Advantages
Delrin offers several production advantages, making it a favorite among engineers and fabricators:
- Good machinability: cuts easily with a smooth finish.
- Exacting cutting characteristics: easy to cut tight, complex components.
- Tight tolerances: maintains dimensional accuracy under load.
- Low tool wear: prolongs the life of a tool, even in large-volume manufacturing.
These characteristics enable manufacturers to produce sophisticated components with reliability, thereby minimizing rework and lost time.
Industrial Applications
Delrin sheets are typically employed in industrial applications as durable, wear-resistant components in which accuracy and long-term reliability are critical:
- Bearing surfaces and bushings allow smooth motion and low friction when subjected to heavy loads, thereby reducing wear in moving assemblies.
- Gears and gear wheels prevent the constant transfer of torque and prevent deformation even under repetitive stress.
- Valve components: ensure sealing integrity and dimensional accuracy in hydraulic and pneumatic systems.
- Parts of the pump: resist fluid exposure to chemical corrosion and fatigue.
- Components of conveyor systems are quiet and have a long service life due to the self-lubricating nature of Delrin.
The low levels of friction and high levels of fatigue resistance of Delrin ensure that it is the ideal material for use in parts subjected to constant movement or mechanical stress.
Automotive Applications
In the car industry, Delrin is a perfect solution in terms of strength, low weight, and hardiness, in such a way that the performance remains consistent under extreme conditions:
- Fuel system parts: Withstand gasoline and solvents while maintaining their dimensions.
- Door mechanisms: operate smoothly and reliably, even under frequent use.
- Safety restraint components must maintain mechanical integrity even in high-impact cases.
- Internal elements are attractive and sustainable in the presence of changing temperatures and humidity.
Delrin can also enhance safety and longevity in modern vehicle designs by resisting vibration, chemical exposure, and thermal expansion.
Food Processing Applications
Delrin is widely used in the food industry because it is FDA-compliant and offers excellent hygienic performance:
- FDA-compliant food contact surfaces are suitable for meeting the regulatory specifications for both direct and indirect food contact.
- Conveyor parts: maintain material flow and ensure easy sanitation production.
- Parts of food processing equipment are highly wear-resistant, reducing downtime and the risk of contamination.
- Components of kitchen appliances: offer structural rigidity and prolonged performance in environments with high moisture levels.
Conclusion
Delrin (POM) sheets offer outstanding mechanical properties, easy machinability and flexible sizing, with excellent cost-effectiveness. As a preferred material for industrial manufacturing, automotive and food processing industries, they meet diverse needs (heavy-load, extreme environments, hygiene standards), ensure precise and durable components.
