Stable Filling
Controlled pressure helps molten metal fill the mold smoothly
Dense Castings
Reduced turbulence and improved feeding for stronger parts
Repeat Production
Suitable for consistent medium to high-volume aluminum parts
Advantages
Advantages of Low Pressure Casting
Low pressure casting is ideal for aluminum alloy parts that require controlled filling, good mechanical properties, stable dimensions and reliable repeatability across production batches.
Smooth Mold Filling
Molten metal enters the mold under controlled pressure, reducing turbulence and helping improve the internal quality of complex aluminum castings.
Improved Casting Density
The controlled feeding process helps reduce shrinkage and porosity risks, making it suitable for parts requiring strength, sealing performance and durability.
Good Dimensional Stability
Low pressure casting can produce consistent shapes and stable dimensions, especially for aluminum parts with moderate complexity and repeat production requirements.
Excellent for Aluminum Alloys
This process is widely used for aluminum alloy components where lightweight structure, strength, machinability and reliable production quality are important.

Quality Assurance
How We Ensure Low Pressure Casting Quality
Low pressure casting quality depends on more than final inspection. We control design review, tooling, melting, pressure filling, solidification, heat treatment, machining and inspection throughout the full process.
01
Drawing & Casting Feasibility Review
We review material grade, wall thickness, draft angles, ribs, sealing surfaces, machining allowance, tolerance zones and assembly requirements before production.
02
Tooling & Mold Preparation
Mold design, gating system, venting, cooling layout and parting line planning are reviewed to support stable filling and repeatable casting quality.
03
Melting, Degassing & Pressure Control
Aluminum alloy melting, melt cleanliness, degassing, temperature and pressure curve are controlled to reduce porosity and improve casting consistency.
04
Heat Treatment, Finishing & Machining
According to part requirements, castings can be heat treated, cleaned, shot blasted, trimmed and CNC machined for holes, threads and precision assembly surfaces.
05
Final Inspection & Delivery Check
Finished parts are inspected for dimensions, surface condition, machining accuracy, visible casting defects, sealing areas and packaging protection before shipment.
Inspection Support Available
WAKING can support customized inspection requirements for low pressure casting projects, especially for aluminum parts requiring dimensional stability, sealing performance and machining accuracy.
