Table des matières
Matériel capable 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 soudage (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.
Aperçu & Cas d'utilisation
Why this solution for automotive & agricultural environments
Production modules and spares move through facilities that impose shock, vibration, and tight takt. Our welded bases and carts are designed around these realities: structural steels (Q235 / S235 et Q355 / S355) provide stiffness and durability; Datums fraisés and machined PCDs ensure accurate location; barres de remorquage, pin receivers, anchor holes, and forklift pockets integrate with existing handling equipment. Where hygiene or aggressive cleaners apply (par exemple., powertrain washdown), we offer 304/316 inoxydable; for lower push force and energy use, 6061/6082 aluminium 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 de 800×600×500 mm à 2000× 1200 × 900 mm).
- Sequencing & kitting carts for trim, électrique, and fasteners, with ESD/grounding pads when electronics are present.
- Tow-train carts pour les courses de lait (manual/tugged/train duty), payloads 200–1500 kg.
- Field service frames with protective bumpers and tie-downs.

FAQ
Q1: Which materials are best for automotive skids and ag frames?
For stiffness and cost efficiency, Q355 / S355 is common. Choisir 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 facteur de sécurité. Exemple: 800 kg payload ⇒ 800/3 ≈ 267 kg × 1.5 ⇒ select ≥400 kg rated casters; diamètre Ø150–200 mm depends on floor and thresholds.
Q3: What tolerances can I call out?
Standard builds meet ISO 13920 B / c et ISO 2768 m / f. Typical guidance: planéité ≤1,0–2,0 mm on datum pads; Connexion ≤ 1,5 mm / m. Tighter features are machined.
Q4: Which weld class do you deliver?
Default ISO 5817 Classe C; classe B applied to visible or critical joints. Structural reference: AWS D1.1 if required by the drawing.
Q5: E-coat, zinc, or powder—what’s right for me?
Map environment to ISO 12944: zinc for sacrificial corrosion protection, coat électronique for edge/cavity coverage, poudre (70–100 μm) for impact and color durability. Duplex systems extend life in severe exposure.
Q6: Can you provide PPAP documentation?
Oui. We support Fai, Control Plan, PFMEA, MSA, PSW, plus WPS / PQR, Coc, VT/DFT/NDT reports as specified.
Q7: What drives price and lead time?
Weld length and class, machined datums/PCDs, spectre, duplex coating, and packaging/dunnage drive cost and schedule. We quote ranges after drawing review.
