Custom Die Casting Services
Die casting for aluminum, zinc, magnesium and copper alloy components, with tooling, secondary operations and inspection defined for each project.
Capacity at a glance
Die Casting Capabilities
Match your component to the alloy, machine capacity and finishing route before planning production.
- Alloy families
- Aluminum · Zinc · Magnesium · Copper alloys
- Machine clamping force
- 180–2,500 metric ton-force (tf); 11 machines
- Aluminum net part weight
- Routine trimmed casting weight: 0.05–10 kg. Castings of 15 kg have been produced for specific large-part projects.
- Zinc net part weight
- Routine trimmed casting weight: 0.005–2 kg. Stable production of 1 g parts has been achieved in specific hot-chamber projects.
- Secondary operations
- CNC machining · Surface finishing · Product assembly
- Precision & acceptance
- Aluminum as-cast controlled features: typically ±0.05–±0.15 mm; general structural dimensions: ±0.10–±0.30 mm. CNC critical dimensions: ±0.02–±0.05 mm, with fixture and process review for ±0.02 mm. Parting-line dimensions are assessed separately.
- Main walls & local thin-wall review
- Typical main walls: aluminum 1.5–4.5 mm; zinc 0.8–2.0 mm. A local 0.7 mm target is considered mainly for Zamak zinc with short flow paths and requires tooling trials.
- Surface roughness by stage
- Typical as-cast surfaces: Ra 3.2–6.3 μm. Ra 0.8 μm is assessed for specified mating or sealing surfaces on aluminum or zinc after CNC finish milling, finish turning or polishing, with process and measurement conditions agreed.
Routine weights refer to single-part castings after gate and runner removal. The 15 kg aluminum and 1 g zinc examples are specific-project experience; each new part requires its own drawing, tooling and process review. Clamping force does not establish part weight, shot weight or the usable part envelope. Magnesium and copper alloy weight ranges require separate review.

From drawing to delivery
Die Casting Manufacturing Workflow
One agreed route connects tooling, casting, secondary operations and the records needed to release your finished part.
- 01
Drawing & DFM
Review geometry, alloy, volume and critical features. Agree drawing revisions and open decisions before tool release.
Tooling & DFM → - 02
Tooling & samples
Manufacture and trial the die. Review sample measurements, corrections and approval before production.
Tool trials & approval → - 03
Die casting
Prepare the alloy and die, cast the component, then trim and deburr against the agreed production requirements.
High-pressure die casting → - 04
Secondary operations
Machine functional features and specify finishes, protected surfaces and assembly interfaces.
Secondary CNC machining → - 05
Inspection & delivery
Complete the agreed checks, reports, identification and packaging before shipment.
Quality & inspection →
Production & verification
Manufacturing and Quality Control
Plan material checks, functional dimensions and finish requirements alongside the production route.
- Material & traceability
- Agree the alloy specification, material records and part or lot identification required for the order.
- Dimensions & interfaces
- Define datums, critical dimensions and delivery state. Select measurement methods and sampling against the drawing.
- Appearance & functional checks
- Confirm finish limits and cosmetic surfaces. For leakage or internal-quality requirements, agree test conditions, acceptance criteria and reporting.
