Hardware capaz 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 MIG automático/robótico soldadura (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.
Descripción general & Casos de uso
Why this solution for automotive & agricultural environments
Production modules and spares move through facilities that impose shock, vibración, and tight takt. Our welded bases and carts are designed around these realities: structural steels (Q235/S235 y Q355/S355) provide stiffness and durability; datums fresados 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 (p.ej., powertrain washdown), we offer 304/316 inoxidable; for lower push force and energy use, 6061/6082 aluminio 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×An×Al de 800×600×500 mm a 2000× 1200 × 900 mm).
- Sequencing & kitting carts for trim, eléctrico, y sujetadores, 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.

Preguntas más frecuentes
Q1: Which materials are best for automotive skids and ag frames?
For stiffness and cost efficiency, Q355/S355 is common. Elegir 304/316 where frequent washdown/corrosion risk exists; pick 6061/6082 aluminum to reduce cart mass and push force.
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. Ejemplo: 800 kg payload ⇒ 800/3 ≈ 267 kg × 1.5 ⇒ select ≥400 kg rated casters; diámetro Ø150–200 mm depends on floor and thresholds.
Q3: What tolerances can I call out?
Standard builds meet YO ASI 13920 ANTES DE CRISTO y YO ASI 2768 M/F. Typical guidance: planitud ≤1.0–2.0 mm on datum pads; cuadrícula ≤1.5 mm/m. Tighter features are machined.
Q4: Which weld class do you deliver?
Default YO ASI 5817 clase C; Clase B applied to visible or critical joints. Referencia estructural: AWS D1.1 if required by the drawing.
Q5: E-coat, zinc, or powder—what’s right for me?
Map environment to YO ASI 12944: zinc for sacrificial corrosion protection, e-carro for edge/cavity coverage, polvo (70–100 μm) for impact and color durability. Duplex systems extend life in severe exposure.
Q6: Can you provide PPAP documentation?
Sí. We support FAI, Control Plan, PFMEA, MSA, PSW, plus WPS/PQR, Coches, VT/DFT/NDT reports as specified.
Q7: What drives price and lead time?
Weld length and class, machined datums/PCDs, caster spec, duplex coating, and packaging/dunnage drive cost and schedule. We quote ranges after drawing review.
