當您需要接近尼龍的承重能力，又必須保護烤漆水泥地或環氧樹脂地面時，聚氨酯是預設選擇。RollMaster 在廠內以灰鐵與鋼芯澆鑄 PU 輪。
PU 輪具備低滾動阻力、良好抓地力、安靜運轉以及耐油與多種化學品的特性——是 AGV/AMR 平台與室內物料搬運的標準輪材。
規格
- 標準蕭氏硬度 92A–95A，其他配方可依需求提供
- 廠內設有射出與澆鑄 PU 產線
- 提供不留痕的灰色與紅色配方
- 使用溫度範圍一般為 -20 °C 至 +80 °C
表面處理
鍍鋅或不鏽鋼支架
| Bracket finish | What it does | Specify it when |
|---|---|---|
| Zinc plating (blue/white) | Baseline corrosion protection | Standard dry indoor use |
| Chrome plating | Hard, decorative, easy to clean | Visible / cleanroom-adjacent equipment |
| Powder coating | Custom color, good corrosion resistance | Brand colors, outdoor-adjacent use |
| Stainless steel 304 | No plating to fail | Washdown, food, medical |
| Stainless steel 316 | Resists chlorides | Salt, brine, marine air, harsh cleaning chemicals |
測試
PU 與芯材的接著強度及硬度逐批次檢驗
| Selection factor | Rule of thumb | Effect on performance |
|---|---|---|
| Load sizing | Total load ÷ 3 (not ÷ 4) | On uneven floors only three wheels carry the cart |
| Wheel diameter | Bigger rolls easier | Larger wheels cut push force and bridge gaps |
| Tread hardness | Softer = quieter, harder = easier rolling | Pick the softest tread that carries the load |
| Bearing choice | Precision ball for manual pushing, roller for heavy loads | Bearings dominate rolling resistance at high load |
| Swivel vs rigid | 2 swivel + 2 rigid is the standard cart setup | All-swivel carts wander; all-rigid carts cannot steer |
| Floor condition | Rough floors need bigger wheels and softer treads | Small hard wheels on bad floors destroy both |
