Q5: E-coat, zinc, or powder—what’s right for me?

Map environment to ISO 12944 : zinc for sacrificial corrosion protection, e-coat for edge/cavity coverage, powder (70–100 μm) for impact and color durability. Duplex systems extend life in severe exposure.

Q: Q1: Which materials are best for automotive skids and ag frames?

For stiffness and cost efficiency, Q355/S355 is common. Choose 304/316 where frequent washdown/corrosion risk exists; pick 6061/6082 aluminum to reduce cart mass and push force.

Q: Q2: How do I select casters and verify load capacity?

Use 3-caster load-sharing for turns and a 1.3–2.0 safety factor. Example: 800 kg payload ⇒ 800/3 ≈ 267 kg × 1.5 ⇒ select ≥400 kg rated casters; diameter Ø150–200 mm depends on floor and thresholds.

Q: Q3: What tolerances can I call out?

Standard builds meet ISO 13920 B/C and ISO 2768 m/f . Typical guidance: flatness ≤1.0–2.0 mm on datum pads; squareness ≤1.5 mm/m . Tighter features are machined.

Q: Q4: Which weld class do you deliver?

Default ISO 5817 class C ; class B applied to visible or critical joints. Structural reference: AWS D1.1 if required by the drawing.

Q: Q6: Can you provide PPAP documentation?

Yes. We support FAI, Control Plan, PFMEA, MSA, PSW , plus WPS/PQR , CoC , VT/DFT/NDT reports as specified.

有能なハードウェア is a China-based OEM/ODM factory delivering welded skids, floor frames, and kitting/tow-train carts engineered for high-utilization automotive and agricultural environments. We combine automatic/robotic MIG 溶接 (with TIG where stainless or cosmetic seams are required), upstream laser cutting, precision machining, and export-ready QA to supply repeatable assemblies that slot into your line-side logistics and PPAP requirements.

Overview & Use Cases

Why this solution for automotive & agricultural environments

Production modules and spares move through facilities that impose shock, 振動, and tight takt. Our welded bases and carts are designed around these realities: structural steels (Q235/S235 そして Q355/S355) provide stiffness and durability; milled datums and machined PCDs ensure accurate location; tow bars, pin receivers, anchor holes, and forklift pockets integrate with existing handling equipment. Where hygiene or aggressive cleaners apply (例えば。, powertrain washdown), we offer 304/316 stainless; for lower push force and energy use, 6061/6082 アルミニウム reduces mass on kitting carts and fixtures.

Typical applications on line-side, kitting, and service operations

Engine/gearbox skids & cradles with machined datum pads for locator repeatability.
Body/cab/axle frames sized to common modules (L×W×H から 800×600×500 mm に 2000×1200×900 mm).
Sequencing & kitting carts for trim, 電気, およびファスナー, with ESD/grounding pads when electronics are present.
Tow-train carts for milk runs (manual/tugged/train duty), payloads 200–1500 kg.
Field service frames with protective bumpers and tie-downs.
