RollMaster 在生产标准目录的同一条产线上开展 OEM 代工、ODM 设计和贴牌生产：冲压、CNC 支架加工、PU 浇铸和最终装配均在自有厂区完成。
定制项目从需求评审和样品开始，经过试产直至批量生产，工程团队全程支持图纸、配方和测试。
规格参数
- OEM / ODM / 贴牌合作模式
- 定制支架：冲压、CNC 加工、焊接
- 定制 PU 配方、硬度与颜色
- 样品 → 试产 → 批量生产爬坡
典型材料
全套厂内材料体系（PU、尼龙、橡胶、钢、不锈钢）
| Wheel material | Typical hardness | Floor protection | Where it fits |
|---|---|---|---|
| Cast polyurethane (PU) | Shore A 92–95 | Very good: non-marking compounds | AGV/AMR, trolleys on painted or epoxy floors, heavy duty |
| Injected PU | Shore A 90–95 | Good | Cost-sensitive medium duty, light equipment |
| Cast nylon (PA6) | Shore D 70+ | Fair: hard tread | High load, dry indoor logistics, washdown |
| Glass-filled nylon | Shore D 75+ | Fair | Higher loads and temperatures than PA6 |
| Solid rubber | Shore A 65–75 | Good | Shock absorption, outdoor thresholds, economy |
| Super-elastic rubber | Shore A 55–65 | Excellent | Quiet running: medical, hotel, laboratory |
| Phenolic resin | — | Fair | Baking lines and ovens up to +280 °C |
| Forged steel | — | None: needs steel plate or heavy concrete | Extreme loads, heat, harsh floors |
| Stainless (wheel/bracket) | — | Good | Food, pharma, washdown, corrosive areas |
表面处理
镀锌、镀铬、定制颜色粉末喷涂
| 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 |
测试与检验
按项目制定专项规格与检验计划
| 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 |
