Complex aluminum components with consistent wall thickness, minimal porosity, and superior mechanical properties — all from in-house LPDC tooling.
Low Pressure Die Casting (LPDC) is a controlled casting method that uses upward pneumatic pressure — typically 0.7 to 1.0 bar — to fill a permanent steel mold from below. Unlike gravity casting, where metal flows in unpredictably, LPDC fills the die steadily and uniformly, resulting in significantly lower porosity, better density, and superior mechanical properties throughout the part.
CANEX develops all LPDC tooling — the permanent steel dies — in-house. This means faster tooling lead times, full dimensional control, and no third-party die costs. The process is ideal for parts that must meet pressure integrity requirements, tight dimensional tolerances, or demanding structural specifications.
Every LPDC component at CANEX begins with upcycled aluminum extrusion scrap from our own production lines as raw material. This closed-loop approach eliminates virgin ingot cost and dramatically reduces the carbon footprint of each casting — a genuine zero-waste circular manufacturing model.
CANEX's LPDC process is a complete closed-loop manufacturing cycle — from upcycled extrusion scrap input to finished, heat-treated, and inspected component output.

LPDC and Gravity Die Casting (GC) are both permanent-mold processes — but their performance characteristics differ significantly. Use this table to determine which is right for your component.
| Property | LPDC | Gravity Casting (GC) |
|---|---|---|
| Casting Density | ✓ Higher — pressure-driven fill | Good — gravity fill |
| Porosity Level | ✓ Lower (controlled fill rate) | Moderate (gravity turbulence) |
| Mechanical Properties | ✓ Superior tensile strength | Good for structural parts |
| Pressure-Critical Parts | ✓ Recommended | Not recommended |
| Wall Thickness | ✓ More consistent | Adequate for most uses |
| Tooling Cost | Moderate | ✓ Lower |
| Cycle Time | Moderate | ✓ Faster for simple parts |

LPDC is the process of choice for structural, pressure-critical, and mechanically demanding aluminum components. Here is why CANEX LPDC delivers superior results.
Superior Density & Strength
The controlled upward pressure fill eliminates turbulence and gas entrapment, producing a denser casting with lower porosity. This directly improves tensile strength, yield strength, and fatigue resistance throughout the component.
Zero-Waste Circular Production
CANEX uses upcycled aluminum extrusion scrap — generated within our own facility — as the raw material for every LPDC pour. This eliminates virgin ingot cost, reduces carbon footprint, and closes the production loop with zero material waste.
In-House Tooling & Full Integration
All LPDC dies are designed and made at CANEX. Combined with in-house machining and surface finishing, we provide a complete manufacturing service from casting to finished component — under one roof, with one quality system.
LPDC is specified for parts where pressure integrity, dimensional consistency, and high mechanical performance are non-negotiable requirements.
