Peliou New Materials Technology Co.,LTD
POM is selected for engineering applications primarily due to its comprehensive properties:
Metal Replacement: Lighter than brass/aluminum, corrosion-resistant, and self-lubricating, reducing weight, noise, and maintenance costs.
High Load & Wear Resist
I. Primary Engineering Applications and Products
1. High-Precision Transmission and Linear Motion Systems
Precision Gears and Racks: Used for small-to-medium power transmission in automation equipment, robotic joints, measuring instruments, and servo mechanisms. Features include extremely low noise and no need for additional lubrication.
Bearings, Bushings, and Sliding Liners: Employed in conveyor guide rails, packaging machinery, and auxiliary motion units for machine tools. Excel in dusty or non-lubricated environments.
Cam and Linkage Mechanisms: Leverage high fatigue resistance and rigidity to achieve complex reciprocating motions.
Synchronous Pulley and Sprocket Systems: Lightweight and wear-resistant, particularly suited for high-speed, light-load transmission.
2. Fluid Handling and Control Systems
Valve Core Components: Ball valve seats, plug valve cores, butterfly valve bearing sleeves, metering pump valve balls. POM resists diverse chemicals and solvents, offers excellent sealing, and ensures smooth operation.
Pump Components: Centrifugal pump impellers, gear pump side plates, diaphragm pump connecting rods and valves. Wear-resistant and resistant to medium corrosion.
Piping System Components: Quick-connect fittings, ferrules, sight glass frames, flow meter rotors. Used in piping systems for chemical, water treatment, and pharmaceutical industries.
3. Automation Equipment & Industrial Machinery
Conveyor System Components: Wear strips, guide blocks, roller end caps, sorter slides. Reduce friction resistance and protect metal rails.
Fixtures & Jigs Parts: Positioning blocks, V-blocks, spring plunger housings. Lightweight, non-scratch on workpieces, dimensionally stable.
Sensor and Actuator Structural Components: Encoder gears, limit switch sliders, pneumatic cylinder end caps and pistons. Ensures motion precision and response speed.
4. Automotive and Transportation (Non-Appearance Parts)
Functional and Fuel System Components: Window regulator gears, door lock actuator parts, seatbelt buckle components, fuel pump module gears or sliders. Requires high reliability and long service life.
Steering system shims and bushings: Reduce friction and noise.
5. Special Environments and Custom Solutions
Food and pharmaceutical machinery: Utilize FDA or EU-compliant food-grade POM for machining filling valves, bottle cap dispenser gears, conveyor chain links, etc., meeting sanitary requirements.
Low-temperature flexible applications: POM maintains excellent impact resistance at low temperatures, suitable for cryogenic fluid valves and moving parts in refrigeration equipment.
Prototyping and Fixtures: During development, CNC-machine POM rods directly into functional prototypes or production fixtures for rapid validation and durability.
Key Engineering Design Considerations
When machining POM rods for engineering components, evaluate:
Long-Term Temperature Rise: Continuous operating temperatures typically not exceeding 80-100°C. Calculate PV values (pressure × velocity) for high-friction areas to prevent thermal softening.
Chemical Compatibility: Resistant to hydrocarbons and solvents, but not to prolonged immersion in strong acids, alkalis, or hot water.
UV Stability: Select UV-resistant grades or implement shielding for long-term outdoor use.
Assembly Stress: POM exhibits low creep, but expansion coefficients must be calculated for tight fits to prevent stress cracking over time.
Summary
Engineering-wise, machined POM rod products inherently offer high-performance, customizable solutions for plastic-to-metal substitution. They most commonly appear in motion-function and fluid-contact components requiring wear resistance, self-lubrication, precision, chemical resistance, and low maintenance. Their value lies not only in material properties but also in enabling rapid response, small-batch high-precision manufacturing through machining—making them a critical engineering material choice for optimizing equipment performance and reducing total cost of ownership.
