DC400T / Medium cold chamber production platform
400 Ton Aluminum Cold Chamber Die Casting Machine
The DC400T combines a listed 4,000 kN clamp, a 700 × 700 mm die opening, and three shot-end choices for aluminum and magnesium production. Approve it as a complete manufacturing platform only after clamp demand, complete shot, die movement, process pressure, automation, utilities, and acceptance scope are documented together.
Published DC400T data reviewed August 9, 2026 by Cathy, Director. Final approved drawings and signed technical documents take precedence.

Model approval brief
Four signatures should support the DC400T decision
Purchasing can compare price, but engineering must first confirm that the same casting and process assumptions pass four independent boundaries. A larger nominal tonnage cannot compensate for an unsuitable shot package, die interface, or cell layout.
Review the machine RFQ checklist →SHORTLIST CONDITION
Consider the DC400T when calculated clamp demand stays inside 4,000 kN with the agreed margin, complete metal demand fits one confirmed pressure-capacity package, the die and all movement clear the published envelope, and the complete production cell can be installed, guarded, operated, and maintained at the destination factory.
- PROCESS
Projected area and pressure
Total cavities, runners, overflows, and pressure-exposed slides. Record alloy, cavity pressure, fill requirement, quality risk, and operating margin.
- TOOLING
Complete shot and die
Include biscuit and process allowance; verify die width, height, thickness, weight, opening, ejection, core pulls, cooling, vacuum, and lifting.
- PRODUCTION
Cycle and automation
Define furnace and dosing, spray, extraction, trim, scrap handling, inspection, changeover, target cycle, shifts, annual output, and recovery sequence.
- PLANT
Utilities and delivery
Confirm floor loading, access route, power, water, air, exhaust, safety standard, documentation, FAT, packing, installation, training, service, and spares.
Shot-end decision lanes
Match capacity and pressure before fixing the plunger
The published 60, 70, and 80 mm packages link metal capacity, intensification pressure, and casting area. The largest package is not automatically safer: capacity increases as listed pressure decreases.

Middle package for a balanced pressure-capacity requirement.
- Aluminum shot
- 5.1 kg
- Magnesium shot
- 3.7 kg
- Intensification pressure
- 82 MPa
- Published casting area
- 550 cm²
Largest listed shot allowance; lowest listed intensification pressure.
Do not use the 1,150 cm² maximum casting area as automatic part approval.
Actual allowable projected area depends on the agreed cavity pressure, pressure-exposed geometry, alloy, quality target, and operating margin. Complete shot demand and die fit remain separate checks.

System evidence
Use machine close-ups to define inspection and maintenance questions
These official system references have been cleaned of Chinese text. They show component families and access areas, not a promise that every visible brand, quantity, or arrangement is included in the final DC400T scope.
SYSTEM 01
Independent high-speed and intensification storage
The published configuration describes separate high-speed and intensification accumulators. Define pressure verification, safe discharge, inspection intervals, gauge accuracy, acceptance evidence, and critical spares in the technical agreement.
SYSTEM 02
Hydraulic pressure and flow control package
Record the quoted component makes, filtration and oil requirements, core-pull groups, service access, diagnostic points, hose and seal spares, and the maintenance documents delivered with the machine.
Production-cell responsibility map
The machine is the center of the cell, not the whole cell
Comparable quotations identify the owner, interface, acceptance evidence, utilities, documentation, and exclusions for every system around the DC400T.
Furnace and dosing
Capacity, energy source, temperature control, alloy change, transfer height, ladler or dosing method, loss assumptions, signals, and safety.

Factory acceptance sequence
Convert the technical agreement into observable evidence
A useful FAT plan is agreed before testing. It states the instruments, limits, sample conditions, records, attendees, pass criteria, and corrective-action process instead of relying on a general statement that the machine ran.

DC400T procurement FAQ
Answers for model selection, scope alignment, and acceptance
Use these answers to keep purchasing, process, tooling, automation, maintenance, and plant teams working from the same approved project inputs.
Q01What is the DC400T aluminum die casting machine best suited for?
The DC400T is an initial candidate for medium aluminum or magnesium projects whose total projected-area calculation, complete shot demand, die envelope, pressure requirement, and cell interfaces fit the listed 4,000 kN clamp and a confirmed 60, 70, or 80 mm plunger package. The 400 ton name is not a substitute for these checks.
Q02What are the main DC400T technical specifications?
Published data lists 4,000 kN clamping force, 550 mm clamping stroke, 265 kN ejecting force, 125 mm ejection stroke, 250-700 mm die thickness, 1,050 x 1,050 mm platens, 700 x 700 mm tie-bar spacing, 405 kN injection force, 570 mm injection stroke, a 22 kW motor, and an approximate machine weight of 17 tons.
Q03How should the 60, 70, or 80 mm DC400T plunger package be selected?
Match complete shot weight and required intensification pressure together. The published aluminum allowances increase from 3.0 to 5.1 kg as plunger diameter rises, while listed intensification pressure decreases from 145 to 82 MPa. Select from the required process window rather than choosing the largest plunger automatically.
Q04How do I check whether 4,000 kN clamping force is enough?
Calculate the projected area of every cavity, runner, overflow, and pressure-exposed slide, multiply by the documented cavity-pressure assumption, then apply the agreed operating margin. Check that result against 4,000 kN separately from shot capacity, die fit, and the published maximum casting area.
Q05When should I compare the DC300T, DC550T, or DC880T?
Compare the DC300T when it satisfies the project with margin and a smaller installed scope. Review the DC550T or DC880T when clamp demand, complete shot, the 700 x 700 mm die opening, 700 mm maximum die thickness, die handling, automation reach, or maintenance clearance crosses a documented DC400T boundary.
Q06What should the DC400T quotation and FAT plan confirm?
The quotation should state the selected shot package, controls, hydraulic components, core-pull groups, die interfaces, furnace and dosing equipment, spraying and extraction automation, guarding, utilities, spares, documents, packing, installation, training, and exclusions. FAT criteria should cover safety, motion, pressure and speed, alarms, recipes, interfaces, documentation, and corrective-action rules.
