Manufacturing Capabilities
Gravity · Low-Pressure · Sand · CNC · Mold — five integrated processes under one roof.
From Order to Delivery — 10 Linked Stages
Order review → mold design → mold-flow analysis → sand core/casting → X-RAY → heat treatment → shot blasting → CNC → quality inspection → shipment. Every stage has a quality-control node.

Gravity Casting
Stable, dense, low-porosity aluminum parts for structural and safety-critical applications.
- Common alloys: ADC12, A380, A356, AC4B, custom alloys on request.
- Part weight range: 0.1 kg – 30 kg.
- Dimensional tolerance: CT7–CT9 (ISO 8062).
- Surface finish: as-cast Ra 6.3–12.5; machined Ra 0.8–3.2.
- Typical lead time: tooling 15–25 days, sample 4–7 days after T1, mass production 15–30 days.
Lower tooling cost than high-pressure die casting.
Excellent mechanical properties for structural parts.
Suitable for medium-to-large parts and small batches.
Low-Pressure Casting
Tight-tolerance parts with excellent mechanical properties, ideal for wheels, motor housings and structural parts.
- Common alloys: A356, A357, AC4C.
- Part weight range: 0.5 kg – 50 kg.
- Dimensional tolerance: CT6–CT8.
- Lower gas porosity than gravity casting; heat-treatable.
- Typical lead time: tooling 20–30 days, sample 7–10 days.
High mechanical strength — heat-treatable (T6).
Excellent pressure tightness for hydraulic & pneumatic parts.
Favored for wheel hubs, motor housings, suspension parts.
Sand Casting
Flexible low-volume production for large, complex or prototype aluminum castings.
- Common alloys: ADC12, A356, custom alloys.
- Part weight range: 0.5 kg – 200 kg.
- Dimensional tolerance: CT9–CT11.
- Sand core capability: 5 dedicated sand core shooters (XYZ955).
- Typical lead time: pattern 7–15 days, sample 5–10 days.
Lowest tooling cost — ideal for prototypes & small batches.
Handles very large and complex geometries.
Wide alloy compatibility.
CNC Precision Machining
3-, 4- & 5-axis precision machining of cast and raw aluminum parts.
- 68 CNC machining centers: 5-axis (6 sets), 4-axis (16 sets), 3-axis (46 sets).
- Machining tolerance: ±0.05 mm typical, ±0.1 mm standard.
- Surface finish: Ra 0.8 standard, mirror polishing on request.
- Cavity, slot, thread and engraving per drawing.
- Typical lead time: 5–10 days for machined parts (post-casting).
High repeatability — full CNC production lines.
Integrated with casting for one-stop delivery.
Supports complex 3D features and tight tolerances.
Mold Design & Tooling
In-house tooling for gravity, low-pressure, sand and die casting — design, simulation, sampling.
- Mold flow & DFM analysis with every new project.
- Tooling materials: H13, S50C, S55C; standard & custom steel.
- Tooling lifetime: 30,000–100,000 shots (gravity); 50,000+ (low-pressure).
- Standard sampling lead time: 4–7 days after T1 approval.
Single-point-of-contact from DFM to sampling.
Reduces trial-and-error & saves weeks.
3 utility patents in mold and casting technology.
