Alloy selection affects castability, mechanical performance, corrosion resistance, thermal behavior, pressure-tightness requirements, secondary machining, surface finishing, and total production cost. Common project requests include A380, A360, and ADC12, but final alloy selection and availability should be confirmed according to part function, production capability, drawing specifications, finish requirements, and the operating environment.
A380
General-Purpose Die Casting Alloy
A widely used general-purpose die casting alloy for housings, brackets, enclosures, covers, and industrial components requiring a practical balance of castability, dimensional performance, mechanical properties, and finishing options.
A360
Corrosion and Pressure-Focused Applications
Often considered for applications where corrosion resistance, fluidity, or pressure-related performance is important. Its suitability should be reviewed against tooling, part geometry, machining, and production requirements.
ADC12
Complex Repeat-Production Components
Commonly used for complex and repeat-production die cast parts, particularly where good castability and consistent production are important. Material specification and regional availability should be confirmed during quotation.
Material-selection note: Final alloy selection should be confirmed against the drawing, applicable material standard, part function, production process, corrosion and pressure requirements, machining depth, surface finish, inspection criteria, and actual supplier availability.
Design Considerations for Aluminum Die Cast Parts
A part may appear suitable for die casting in CAD but still create tooling, filling, solidification, ejection, porosity, distortion, machining, or cosmetic problems during production.
Early DFM review helps identify design conditions that can increase tooling complexity, shorten die life, create inconsistent casting quality, or add unnecessary secondary operations.
Industry guidance on alloy data, tooling, tolerances, GD&T, design practices, and quality assurance is available through the NADCA Product Specification Standards for Die Castings.
Uniform Wall Thickness
Consistent wall thickness supports more predictable metal flow, cooling, solidification, and dimensional stability. Sudden transitions between thick and thin sections can increase the risk of shrinkage, porosity, hot spots, distortion, and inconsistent filling.
Draft for Part Release
Draft should be applied to surfaces that move relative to the die during ejection. Insufficient draft can increase ejection force, damage surfaces, accelerate die wear, and make cosmetic requirements harder to control.
Ribs and Bosses
Ribs and bosses can add stiffness, support fasteners, and integrate mounting features without creating fully solid sections. Their thickness, spacing, fillets, draft, and relationship to surrounding walls should be reviewed to reduce sink, porosity, and stress concentration.
Fillets and Radii
Sharp transitions can restrict metal flow, concentrate stress, and create difficult tooling conditions. Practical fillets and radii support smoother filling, stronger geometry, and more durable die details.
Parting Lines and Ejector Marks
Parting-line location affects flash, trimming, cosmetic appearance, dimensional control, and tooling complexity. Ejector-pin locations should also be reviewed early, particularly on sealing, mating, visible, or highly loaded surfaces.
Gates, Overflows, and Venting
Gating, overflow, and venting strategy influence how the cavity fills and how air and gases are displaced. Critical surfaces, thick sections, isolated features, and pressure-sensitive areas should be identified before die design begins.
Undercuts, Slides, and Cores
Undercuts may require slides, lifters, movable cores, or secondary operations, increasing tooling complexity, maintenance, cycle time, and production cost. Unnecessary undercuts should be eliminated or simplified, and unavoidable features should be identified before tooling begins.
Porosity and Pressure-Tight Features
Die castings can contain internal porosity. Parts requiring leak resistance, pressure containment, welding, deep machining, or highly loaded sections require early discussion of allowable porosity, machining depth, testing, and acceptance criteria.
Machining Stock and Critical Tolerances
Critical bores, sealing faces, bearing fits, thread locations, and tight positional relationships may require secondary CNC machining. Machining stock, datums, fixturing surfaces, and inspection requirements should be defined before tooling is released.
From CAD Review to Production Die Casting
Every die casting project should begin with the application, drawing requirements, and expected production program—not tooling price alone. The production route is defined through technical review before tooling and production commitments are made.
Technical RFQ Review
We review CAD files, drawings, alloy requirements, part function, quantities, annual volume, tolerances, cosmetic surfaces, machining, finishing, inspection, packaging, and delivery expectations.
DFM and Tooling Evaluation
Part geometry, wall thickness, draft, ribs, bosses, parting lines, slides or cores, ejection, porosity-sensitive regions, machining stock, and tooling requirements are evaluated.
Tooling, Sampling, and Approval
After technical and commercial approval, tooling is prepared and initial samples are evaluated against drawing requirements, critical dimensions, appearance, machining, and requested documentation.
Production, Inspection, and Delivery
Approved production includes casting, trimming, secondary operations, finishing, inspection, packaging, and delivery according to the agreed project scope.
Prototype to Production Planning for Die Cast Parts
High-pressure die casting normally requires dedicated tooling, which means it is not automatically the best process for the earliest prototype stage.
When the main goal is to validate geometry, assembly fit, functional interfaces, or machining features, prototype parts may first be produced using precision CNC machining services or industrial 3D printing services before die casting tooling is released. These processes do not reproduce every die-cast material or process characteristic, but they can reduce the risk of committing to tooling before the design is stable.
In some projects, plastic injection molding may also be evaluated when the required material, part function, geometry, production volume, and tooling economics indicate that a polymer component may be more appropriate than an aluminum casting.
When short-run tooling, bridge tooling, or direct production tooling is considered, Davion reviews expected volume, alloy, geometry, tool life, approval requirements, production timing, and the cost of future design changes.
Secondary Operations and Quality Support
Die cast parts may require machining, finishing, assembly, and inspection to meet final dimensional, functional, cosmetic, and documentation requirements. These operations should be identified before quotation so the complete production route can be evaluated.
Secondary CNC Machining
Critical bores, threads, sealing faces, bearing locations, mounting surfaces, datum features, and other precision interfaces can be machined after casting.
Drilling, Tapping, and Reaming
Secondary hole-making operations can support threaded features, inserts, dowel locations, fasteners, fluid passages, and assembly interfaces.
Trimming and Deburring
Gates, runners, flash, and sharp edges are removed according to drawing, cosmetic, assembly, and safe-handling requirements.

Aluminum Die Casting Services in Dallas, TX: FAQ
Review answers to common engineering and procurement questions about aluminum die casting, tooling, prototypes, alloys, production volumes, tolerances, porosity, secondary machining, and quote requirements.
What is aluminum die casting, and when is it the right process?
Aluminum die casting is a manufacturing process in which molten aluminum is injected under pressure into a reusable steel die. It is commonly evaluated for repeat-production parts that require complex geometry, integrated ribs and bosses, relatively thin walls, controlled surfaces, and consistent part-to-part production. Whether it is the right process depends on geometry, alloy, production volume, tooling investment, tolerances, secondary operations, performance requirements, and total program cost.
What types of parts are suitable for aluminum die casting?
Common applications include housings, enclosures, covers, brackets, frames, motor and gearbox bodies, actuator housings, thermal-management components, automation parts, and other OEM components with integrated mounting or structural features. A part may be a strong candidate when several features can be consolidated into one near-net-shape casting. Final suitability still depends on size, wall thickness, tooling complexity, alloy, volume, machining, cosmetic requirements, and end-use conditions.
Is aluminum die casting suitable for prototype parts?
High-pressure die casting normally requires dedicated tooling, so it is not automatically the most economical process for the earliest prototype stage. CNC machining or 3D printing may first be used to validate geometry, assembly fit, interfaces, and functional features before die casting tooling is released. Short-run, bridge, or production tooling can then be evaluated according to expected volume, design maturity, approval requirements, timing, tool life, and the cost of future design changes.
Which aluminum alloys are commonly used for die casting?
Common project requests include A380, A360, and ADC12. A380 is widely considered for general-purpose die cast components, while A360 may be evaluated where corrosion resistance, fluidity, or pressure-related performance receives greater emphasis. ADC12 is frequently specified in international repeat-production programs. Final selection must be confirmed against the drawing, applicable material standard, mechanical and environmental requirements, machining, finishing, process capability, and actual material availability.
What production volume makes aluminum die casting economical?
There is no universal minimum quantity that makes die casting economical. The decision depends on tooling cost, part geometry, component size and weight, alloy, cycle requirements, secondary machining, finishing, inspection, annual demand, program life, and the cost of alternative processes. A lower-volume program may still justify tooling when the casting consolidates several components or significantly reduces machining, while a simple part may remain more economical to machine at similar quantities.
Can aluminum die cast parts hold tight tolerances?
Die casting can provide repeatable near-net-shape geometry, but achievable tolerances depend on part size, feature location, die construction, alloy, thermal behavior, process control, tooling condition, and measurement method. Critical bores, sealing faces, bearing locations, threads, datum features, and tight positional relationships may require secondary CNC machining. Functional tolerances should be identified before tooling so machining stock, fixturing, datums, and inspection requirements can be planned correctly.
How should porosity and pressure-tight requirements be handled?
Internal porosity can occur in die cast components because of gas entrapment, solidification shrinkage, metal flow, thick sections, thermal conditions, and process variables. Parts requiring leak resistance, pressure containment, welding, deep machining, or highly loaded sections should identify these conditions during RFQ and DFM review. Required test methods, test pressure, allowable leakage, machining depth, inspection scope, and acceptance criteria should be defined before tooling and production commitments are made.
What information is needed for an aluminum die casting quote?
The strongest RFQ package includes a 3D CAD file, 2D technical drawing, preferred alloy or performance requirements, initial order quantity, estimated annual volume, critical tolerances, machining requirements, cosmetic and surface-finish expectations, inspection and documentation needs, packaging, delivery location, and target timing. When some information is not yet available, the existing files and project requirements can be submitted for initial technical review.
