01
Engineering & Development
Simulation · tooling · prototyping
- Casting simulation: filling & solidification analysis (MAGMAsoft) — porosity solved before the mould is cut
- Tooling & fixture design: casting moulds, fixtures, cutters and gauges designed in-house
- Rapid prototyping: soft tooling 15–25 days / 3D printing 7–30 days / CNC engraving 5–20 days
- DFM support: casting-geometry optimization; technical review → samples → PPAP → series release
4 capability nodes
Ingots · plates · recycled systems
- Aluminum ingots: ZL101A / ZL104 / ZL108 / ZL111 and more; in-house ingot batching, every melt spectrometer-checked
- Aluminum plates: small plates, large plates and general plates for new-energy end plates and sealing plates
- Recycled systems: ADC12 recycled aluminum and sand regeneration, RoHS 2.0 compliant, ratio adjusted on request
- Customer-specified material: designated grades, origins or imported ingots purchased on request, re-inspected on arrival with certificates
4 capability nodes
LPDC · gravity · HPDC · sand
- Low-pressure die casting: our core process — laminar filling for low porosity; up to inline-6 blocks / e-motor housings < 800 mm
- Gravity die casting: 5-way cylinder-head machine + tilting gravity machine; inline-4 heads / Ø 500 mm end covers
- Resin sand & cores: sand cores for complex internal cavities, with in-house sand regeneration
- High-pressure die casting: thin-wall, high-volume small and mid-size parts — we manage the tooling interface, first article and batch acceptance, and follow-on machining
- Sand casting: supplementary process for one-offs and small lots; drawing and process defined by us, full re-inspection on return
5 capability nodes
VMC · drill-tap · HMC · gantry · turning
- Vertical machining centers: 1100–1300 series with 4th axis, multi-face machining in one setup; 10,000 heads + 30,000 housings per year
- Drill-tap centers: LK T5 / T7 — small hole groups and thread clusters; 100% go/no-go gauge inspection on threads
- Horizontal machining centers: multi-face rotary machining for housing-type parts with tight true-position requirements
- Gantry machining centers: face machining for large plates and big housings
- Turning / mill-turn: flanges, sleeves and other rotational parts, roundness and coaxiality controlled to drawing
5 capability nodes
TIG · cold weld repair
- TIG welding & repair welding: casting-defect repair and structural welding; quality confirmed before welding, appearance / penetrant / X-ray re-inspection after
- Cold-weld repair: local repair of mould cavities and non-critical casting zones, with appearance and dimension re-checks after repair
2 capability nodes
CMM · 3D scanning · grinding
- Precision CMM inspection: Hexagon automatic CMM (≤ 2.0 µm, CAD comparison) + Mitutoyo manual CMM (≤ 3.0 µm)
- 3D laser scanning: FARO, 0.4 mm — full-form deviation color maps for first articles; reverse engineering without drawings supported
- Bore fine-boring & liner pressing: bore roundness / cylindricity / roughness controlled to drawing, re-measured after pressing and archived
- Surface / cylindrical grinding: sealing and mating faces ground to Ra and flatness per drawing
4 capability nodes
Powder · paint · anodizing · plating
- Powder coating: pickling pretreatment + electrostatic powder; film thickness and adhesion testable, colors mixed to RAL
- Painting: flexible small-batch, multi-color response with local touch-up support
- Anodizing (incl. hard anodizing): sulfuric / hard anodizing to customer film thickness and hardness; film re-checked on return
- E-coating: uniform coverage of internal cavities and edges; salt-spray performance verifiable
- Plating: zinc / nickel / chromium to standard thickness; dehydrogenation can be arranged
5 capability nodes
Export packing · door-to-door
- Export packing: standard pallet + carton + EPE liner + export markings; fumigated pallets per destination-country requirements
- Domestic packing: custom-fit liners for your containers, ready to go straight onto the line
- Door-to-door & inventory: export customs and booking assistance; weekly / monthly pull planning, agreed safety stock, expedite contingencies
3 capability nodes
T/T · bank acceptance
- Telegraphic transfer (T/T): deposit + balance against B/L copy or similar structures; RMB or foreign currency
- Bank acceptance bills: rated by bank tier (state-owned / city commercial); discount costs transparent
- Commercial acceptance bills: available after credit assessment and approval
