Run all teams from the same revision-controlled inputs. The platform remains provisional when any calculation, drawing, interface, site condition, acceptance method, or commercial owner is missing.
Complete-shot balance
Include castings, runners, biscuit, overflows, and process allowance. Match the total with one exact plunger package and the pressure needed to deliver the approved quality window.

Owner: purchasing + qualityDossier 02 / Shot-end boundary
Request paired values—do not engineer from range endpoints
The manufacturer publishes DC2500T boundary ranges. The order needs an exact schedule for every offered 140–180 mm plunger diameter: aluminum and magnesium capacity, intensification pressure, casting area, sleeve dimensions, injection datum, velocity basis, and supplied interfaces.
Approval instruction
Select the smallest confirmed package that clears complete shot while preserving the required pressure and agreed process margin.

Dossier 04 / Die and movement release
A 1,500 mm opening is only one line in the die-fit file
Approve the complete die as an operating system, not a rectangular envelope. Include every movement, service, lifting condition, access route, safe state, maintenance task, and changeover step.
Static fit
Overall width and height, 700–1,800 mm thickness, platen contact, tie-bar clearance, mounting pattern, shot sleeve, ejector, manifolds, hoses, connectors, sensors, and guarding.
Dynamic clearance
Opening, ejection, slide and core travel, robot approach, spray reach, extraction path, part orientation, collision zones, hose flex, maintenance removal, and failure recovery.
Mass and handling
Fixed and moving-half weights, center of gravity, lifting points, crane capacity and coverage, die cart, insertion alignment, storage, preheat, transfer, and change-time evidence.
Thermal and quality services
Cooling and heating circuits, flow and temperature control, vacuum, venting, lubrication, spray recipe, leak detection, filtration, monitoring, traceability, and approved connection schedule.

These cleaned reference crops help teams discuss access and interfaces. They do not approve a component make, configuration, guard, color, hose route, shot package, option, or maintenance clearance.

Dossier 08 / Procurement FAQ
Questions to close before project approval
Use these answers for initial screening, then control project calculations, drawings, interfaces, responsibilities, tolerances, test conditions, and evidence in the signed technical agreement.
Q-01What projects should shortlist the DC2500T aluminum die casting machine?
The DC2500T is an initial candidate for very large aluminum or magnesium programs whose documented clamp demand, complete shot, required pressure, die envelope, movement, automation, and plant interfaces fit the published 25,000 kN platform. The 2,500 ton label alone does not approve the casting, die, cycle, quality plan, or factory investment.
Q-02What are the principal DC2500T technical specifications?
Published data lists 25,000 kN clamping force, 1,500 mm clamping stroke, 750 kN ejecting force, 300 mm ejection stroke, 700-1,800 mm die thickness, 2,350 x 2,350 mm platens, 1,500 x 1,500 mm tie-bar spacing, 1,800 kN injection force, 1,100 mm injection stroke, 135 kW motor power, a 3,000 L oil tank, and approximate 165 ton machine weight.
Q-03How should the DC2500T shot-end package be selected?
Published boundaries cover 140-180 mm plunger diameters, 30-55 kg aluminum shot, 21.6-39.6 kg magnesium shot, 115-70 MPa intensification pressure, and 2,150-3,500 cm2 casting area. Obtain the exact paired values for every offered diameter and approve complete shot and pressure together; do not create a purchase configuration by interpolating range endpoints.
Q-04How do I check whether 25,000 kN clamping force is sufficient?
Total the pressure-exposed projected area of all cavities, runners, overflows, and slides, multiply by the agreed cavity-pressure basis, then apply the documented operating margin. Compare that result with 25,000 kN separately from shot capacity, die fit, and the published 6,250 cm2 maximum casting area.
Q-05What factory planning is required for a 165 ton DC2500T?
Approve shipping splits, transport route, unloading and rigging, centers of gravity, crane coverage, foundation and anchor loads, floor capacity, the 14 x 4.6 x 4.5 m bare-machine envelope, die-change and service routes, electrical and cooling duties, exhaust, guarding, oil containment, and all peripheral footprints from approved drawings.
Q-06What should a comparable DC2500T quotation and acceptance plan contain?
Require the selected shot end, controls, hydraulics, core pulls, cooling and vacuum interfaces, furnace and automation ownership, safety scope, utilities, drawings, software, manuals, spares, packing, installation, training, warranty, exclusions, and change-control route. FAT and SAT must define conditions, instruments, samples, data, pass criteria, corrective actions, and retest responsibility.
