Custom Aluminum Die Casting Services for OEM Programs
Aluminum die casting is used to produce repeatable, near-net-shape metal components with complex geometry, integrated ribs, bosses, mounting features, controlled surfaces, and practical strength-to-weight performance. The process is especially valuable when production volume, component complexity, part consolidation, and repeatability justify dedicated tooling.
Davion Manufacturing supports custom aluminum die casting projects from initial CAD and drawing review through tooling strategy, sampling, production, secondary machining, finishing, inspection, packaging, and repeat orders. The complete production route is evaluated before tooling commitments are made.
For engineering and procurement teams comparing aluminum die casting manufacturers or suppliers, the objective should not be tooling price alone. Alloy selection, die design, process control, machining requirements, finishing, inspection, expected annual volume, and program life must be evaluated as one commercial and technical system.

Finished-Part Requirements
Project scope may include trimming, secondary CNC machining, drilling, tapping, surface finishing, inserts, hardware installation, assembly, dimensional inspection, documentation, packaging, and delivery.
Capability note: As-cast dimensional requirements, wall thickness, tooling construction, production volume, lead time, and achievable tolerances are project-specific. Critical bores, sealing faces, bearing locations, threaded features, datum surfaces, and other precision interfaces may require secondary CNC machining.
Common Aluminum Die Cast Parts
Custom aluminum die casting is commonly evaluated for production components that combine structural geometry, mounting features, thermal-management requirements, controlled surfaces, and repeatable manufacturing. Final process suitability depends on part size, wall thickness, alloy, tooling complexity, annual volume, tolerances, machining, appearance, and end-use requirements.
Housings and Enclosures
Electronic housings, control enclosures, sensor bodies, protective covers, communication-device housings, and industrial equipment enclosures.
Motor and Gearbox Housings

Automation and OEM Components
Machine parts, robotics components, actuator bodies, sensor housings, covers, frames, and custom production components used in industrial systems.
Aluminum Die Casting Alloys and Material Selection
Alloy selection affects castability, fluidity, mechanical performance, corrosion behavior, thermal conductivity, pressure-related requirements, secondary machining, finishing response, and total production cost. The correct alloy should be selected against the complete application rather than a single property.
A380
General-Purpose Die Casting Alloy
A widely used general-purpose aluminum die casting alloy for housings, brackets, enclosures, covers, and industrial components requiring a practical balance of castability, mechanical performance, dimensional behavior, and finishing options.
A360
Corrosion and Pressure-Focused Applications
Often evaluated when corrosion resistance, fluidity, or pressure-related performance receives greater emphasis. Its suitability must still be reviewed against tooling, geometry, machining, production requirements, and material availability.
ADC12
Complex Repeat-Production Components
Frequently specified in international repeat-production programs for complex aluminum die cast components. Applicable material specifications, regional availability, mechanical requirements, machining, and finishing should be confirmed during quotation.
A383
Thin-Wall and Intricate Geometry
Commonly considered for components with complex geometry or thinner features where improved filling behavior may be valuable. Final selection depends on the drawing, wall thickness, performance requirements, and production source.
A413
High Fluidity for Leak-Sensitive Components
May be evaluated for applications where fluidity and pressure-related performance are important. Part geometry, porosity requirements, machining depth, sealing conditions, and test criteria require early engineering review.
Design for Manufacturability in Aluminum Die Casting
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
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 machining. Machining stock, datums, fixturing surfaces, and inspection requirements should be defined before tooling is released.
Current tooling, alloy, tolerance, GD&T, design, and quality guidance should be verified against the applicable project requirements and the latest industry references, including the NADCA Product Specification Standards for Die Castings.
Custom Aluminum Die Casting Tooling Strategy
Die casting tooling should match the maturity of the design, alloy, part geometry, sample requirements, initial quantities, expected annual demand, program life, cosmetic requirements, maintenance plan, and the cost of future engineering changes.
Tool material alone does not define die capability. Cavities, slides, cores, inserts, gating, venting, cooling, ejection, surface requirements, sampling, maintenance, ownership, storage, and production expectations must be evaluated as one tooling system.
Prototype and Bridge Tooling
Prototype or bridge tooling may support initial die cast samples, design validation, pilot production, early program quantities, or interim demand while the design and long-term production strategy are being finalized. Tool construction depends on alloy, geometry, quantities, approval requirements, timing, and revision risk.
Production Die Casting Tooling
Production tooling is planned for stable repeat manufacturing, defined annual demand, controlled quality, expected program life, and ongoing production. Die steel, cavities, slides, cores, inserts, cooling, ejection, spare components, and expected maintenance should be defined against the complete production program.
Tool Maintenance and Change Control
Tool ownership, storage, preventive maintenance, repair responsibility, spare inserts, approved production location, engineering changes, drawing revisions, tool modifications, and end-of-program requirements should be documented before the production program begins.
Tooling note: Initial tooling price should not be evaluated independently from expected tool life, sample approval, production volume, maintenance, secondary machining, inspection, finishing, and the commercial impact of future design changes.
From Aluminum Die Casting RFQ to Production Parts
Each aluminum die casting program begins with the application, drawing requirements, expected production volume, and complete finished-part scope. Technical and commercial requirements are clarified before tooling and production commitments are made.

Prototype, Tooling, and Production Planning
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.

Aluminum Die Casting Services: Frequently Asked Questions
Review answers to common engineering and procurement questions about custom aluminum die casting, tooling, alloys, prototypes, production volumes, tolerances, porosity, secondary machining, finishing, inspection, and RFQ 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.
