Low Pressure Die Casting

FUERD is a professional aluminum low pressure die casting manufacturer with 18 years of experience, supporting custom casting projects from drawing review and process development through stable mass production. We supply high-strength A356-T and A357 aluminum castings and support customized alloy grades including ZL101, ZL102, 6061 and 7075 according to project requirements. Our one-stop service covers engineering review, mold development, custom casting, CNC machining, surface finishing, inspection and product assembly.

Key advantages of FUERD low pressure casting:

• T6 Heat Treatable: Low pressure castings support T6 heat treatment to improve tensile strength, toughness and fatigue resistance.
• High Strength and Airtightness: Stable low-pressure filling creates a dense structure for load-bearing and sealing components.
• 3.5mm Thin-Wall Capability: We stably manufacture ultra-thin-wall aluminum castings with uniform wall thickness.
• 100% X-Ray Inspection: Every casting undergoes X-ray non-destructive testing to screen for porosity and shrinkage.

Unlike standard high-pressure die casting, low pressure casting fills the mold steadily and supports T6 heat treatment. This combination helps produce dense, high-strength aluminum components for demanding load-bearing, sealing and heat-dissipation applications.

FUERD combines casting process optimization, controlled production, T6 heat treatment and precision CNC machining, dimensional inspection, mechanical testing, airtightness testing, surface finishing and assembly. Before tooling and production, our engineering team reviews part structure, wall thickness, machining allowance, critical tolerances and sealing requirements to identify potential manufacturing risks. This integrated workflow helps reduce tooling revisions and maintain consistent quality from trial casting through large-scale production.

Our custom LPDC parts serve automotive, motorcycle, marine, generator, electrical, hydraulic and mechanical applications. Available solutions range from load-bearing structures and pressure-tight housings to thin-wall heat-dissipation components and precision-machined assemblies.

FUERD provides one-stop custom LPDC manufacturing from engineering review and mold development through casting, machining, inspection, finishing and assembly. Based on customer drawings and working conditions, we evaluate alloy selection, wall thickness, machining allowance, sealing requirements and critical dimensions before production. We support both small-batch trial orders and stable large-scale mass production.

Low pressure die casting uses stable, controlled pressure to fill the mold. The gradual filling process supports a dense internal structure and consistent wall thickness, helping reduce porosity and shrinkage in parts that require mechanical strength, sealing performance or precision machining.

1. Drawing and DFM Review: Our engineering team reviews casting structure, wall thickness, draft, machining allowance, critical tolerances and the gating system to identify potential casting or machining risks before tooling.
2. Mold and Sand Core Preparation: The mold and any required sand cores are prepared for the component geometry.
3. Mold Closing and Controlled Filling: Molten aluminum fills the mold steadily under controlled low pressure.
4. Solidification and Part Removal: The casting solidifies before the mold is opened and the part is removed.
5. T6 Heat Treatment: Heat treatment is applied when required to improve mechanical performance.
6. Machining and Finishing: Parts can be CNC machined, deburred, shot blasted, ground, anodized, coated or polished.
7. Inspection and Assembly: X-ray, dimensional, mechanical and airtightness inspections are completed before assembly or shipment.
