Rilsamid AMNO Dimensional Integrity & Low-Temperature Impact Profile
Rilsamid® AMNO is an unreinforced, natural-grade Polyamide 12 resin. Its paraffin-like molecular chains absorb virtually zero environmental moisture, providing outstanding dimensional repeatability in critical dynamic environments:
| Physical & Strength Metrics | 乾燥成形（DAM）値 | Performance Advantage for Fluidics |
|---|---|---|
| Density & Lightweighting | 1.01 g/cm³ | The lowest density among all structural polyamides, offering substantial weight savings in automotive and aerospace plumbing lines. |
| サブゼロノッチなし衝撃 | No Break (at -30°C) | Maintains exceptional polymer matrix toughness and flexibility, resisting brittle shatter under severe freezing impact. |
| Moisture Dimensional Swell | Water Absorption 0.20% (DAM 24h) | Elimitnates hydro-induced dimensional swelling common to PA6/PA66, securing flawless tight-tolerance seals. |
Fluid & Dynamic Process Configurations for Rilsamid AMNO
With its high molecular orientation and chemical stability, Rilsamid AMNO processes reliably across technical molding applications:
| 成形技術 | Operational Configuration & Details |
|---|---|
| Precision Automotive Fluid Connectors | Excellent. Highly optimized for quick-connect fuel couplers, vacuum line fittings, pneumatic hoses, and urea pipeline connectors requiring extreme hydrocarbon resistance. |
| Biocompatible Medical Catheters & Tubing | Excellent (via AMNO MED grade). Perfect for thin-walled minimally invasive surgical catheters, diagnostic fluid guides, and surgical bobbins complying with USP Class VI. |
| Dynamic Wear-Resistant Guides | Excellent. Highly suitable for structural sliding blocks, dynamic silent gears, cable guides, and dynamic wear washers in sports gear and aerospace fittings. |
Rilsamid AMNO Scientific Molding Requirements
While PA12 has the lowest moisture absorption among polyamides, its high molecular weight requires precise gate placement and thermal uniformity to prevent pressure drops and weld line separation:
1. S136 Mirror-Polished Molds (Weld Line Optimization)
Due to PA12’s low viscosity, gate placement is key to preventing weld line separation on thin-walled couplers. Jucheng’s tooling division uses premium S136 stainless steel hardened to 48–52 HRC, mirror-polished on our 5-axis CNCs. This ensures dynamic fluid components release cleanly without drag marks.
2. Low Shrinkage Dimensional Control
Rilsamid AMNO exhibits low and predictable shrinkage (0.50% to 0.70%). We machine balanced cooling circuits directly into core blocks using conformal geometries to optimize crystallization variables and maintain micro-tolerance diameters.
3. Precise Melt & Die Temperature Controls
Processing melt temperatures are maintained between 210°C and 260°C (410°F to 500°F). Mold temperatures are kept at 20°C to 60°C (68°F to 140°F) using pressurized water heaters to maximize mechanical toughness and prevent flash.
4. Desiccant Pre-Drying Protocol
Raw polymer must be dried in desiccant hopper dryers at 80°C–90°C (176°F to 194°F) for 4–6 hours to ensure moisture levels remain strictly below 0.05% to avoid hydrolytic splay and bubble formation.
