1
What properties do copper castings have?
Industrial copper castings own excellent properties including high electrical conductivity, superior thermal conductivity, great corrosion resistance, wear resistance and stable structural strength.
2
How do you ensure internal quality?
We use X-ray inspection, ultrasonic testing, and pressure testing to ensure internal integrity.
3
What is the production volume range for low pressure casting?
Suitable for medium to high volume with stable quality and high consistency.
4
Can you produce custom low pressure casting parts?
Yes, we accept customized low pressure casting projects with full OEM service.
5
Do you provide heat treatment for low pressure castings?
Yes, T5/T6 heat treatment is standard to achieve optimal mechanical properties.
6
What aluminum alloys are used in low pressure casting?
A356, A357, AlSi7Mg, and other high‑performance casting alloys.
7
Can low pressure cast parts pass pressure testing?
Yes, they are widely used in hydraulic and pneumatic systems requiring high leakproofness.
8
Is low pressure casting better than gravity casting?
It offers higher density and better pressure resistance, but has relatively higher equipment cost.
9
What parts are typically made by low pressure casting?
Automotive wheels, cylinder heads, pump bodies, valve bodies, high‑pressure hydraulic parts.
10
What are the main benefits of low pressure casting?
High internal density, excellent pressure tightness, uniform structure, suitable for high‑performance safety parts.
11
What is aluminum low pressure casting?
It uses low pressure to push molten aluminum upward into the mold, resulting in high density and low porosity.
12
What is the difference between PDC and GDC?
PDC (Pressure Die Casting) and GDC (Gravity Die Casting) are two common aluminum casting processes, differing in filling method, equipment, and application — here’s a detailed comparison:
Filling Method: PDC uses high pressure (10–150 MPa) and high speed (10–50 m/s) to inject molten metal into the die; GDC relies ongravity alone (no external pressure) to fill the mold, with a slow filling speed (0.1–0.3 m/s).
Production Efficiency: PDC is much faster (cycle time 10–60 seconds per piece, daily output up to 10,000 pieces) for mass production; GDC is slower (cycle time 2–5 minutes per piece, daily output up to 500 pieces) for medium batches.
Part Quality: PDC offers higher precision (tolerance IT8–IT10, surface roughness Ra 0.8–1.6 μm) but may have internal porosity; GDC has better internal density (porosity rate ≤1%) and is more suitable for heat treatment, with slightly lower precision (tolerance CT7–CT10, Ra 1.6–3.2 μm).
Cost: PDC has higher initial tooling costs (30–50% more than GDC) but lower unit costs for large batches; GDC has lower mold costs, making it ideal for small to medium batches (500–10,000 pieces).
Applications: PDC for high-volume, small-to-medium complex parts (e.g., electronic housings, automotive parts); GDC for thick-walled, high-strength parts (e.g., engine blocks, hydraulic components).
