DC300T / Production-cell planning platform
300 Ton Aluminum Cold Chamber Die Casting Machine
The DC300T combines a listed 3,000 kN clamp with three shot-end choices for aluminum and magnesium work. Approve it only after the projected area, complete shot, die envelope, required pressure, automation, utilities, and acceptance scope have been reviewed as one production system.
Published DC300T data reviewed August 9, 2026 by Cathy, Director. Final signed technical documents take precedence.

Start with the production mission
Is the DC300T the right machine, not simply the next size?
The model is a defensible shortlist only when five independent checks pass. Do not use aluminum part weight as a substitute for projected area, die geometry, or process pressure.
Short answer
Consider the DC300T when the calculated clamp demand stays within 3,000 kN with the agreed margin, the complete metal demand fits one pressure-capacity package, the die clears the 580 x 580 mm opening and 250-700 mm thickness range, and the required cell interfaces can be documented.
- 01
Clamp demand
Total every pressure-exposed projected area, including runners, overflows, and applicable slides. State the cavity-pressure assumption and margin.
- 02
Complete shot
Include all cavities, runners, biscuit, overflows, and process allowance. Check aluminum or magnesium mass against the selected plunger package.
- 03
Die and movement
Verify width, height, thickness, weight, opening, mounting, ejection, core pulls, lifting route, cooling, and maintenance access.
- 04
Process window
Match fill profile, intensification pressure, plunger, shot sleeve, injection position, thermal control, vacuum, and quality target.
- 05
Cell and factory
Define furnace, ladler, sprayer, extractor, trimming, conveyors, guarding, utilities, floor plan, safety, documentation, and service boundary.
Pressure-capacity tradeoff
Three DC300T shot packages, three different process windows
The published packages link plunger diameter, metal capacity, intensification pressure, and casting area. Select the smallest package that satisfies the complete shot and required pressure with an agreed process margin.

Machine-zone review
Use the visible machine areas to write better RFQ questions
These are crops from the cleaned DC300T configuration reference, not separate machines. They help teams discuss interfaces and access without implying that every shown component is included.
ZONE 01
Clamping enclosure and automatic extraction interface
Confirm platen access, die-change clearance, moving and fixed-side services, extractor or robot interface, guarding boundary, maintenance doors, and the sequence included in the control program.
ZONE 02
Injection unit, accumulators, and shot-end service zone
Specify the plunger and shot-sleeve package, injection positions, accumulator inspection method, pressure gauges, hydraulic brands, safe discharge procedure, service clearance, and recommended critical spares.
Complete cell boundary
The base machine is only one line in the investment
A comparable quotation must define molten-metal handling, die services, automation, downstream equipment, safety, utilities, documentation, and commissioning responsibilities around the DC300T.

DC300T procurement FAQ
Answers for model screening, quotation, and acceptance
Use these answers to align purchasing, process, tooling, maintenance, and plant teams before the technical agreement is signed.
Q01What is the DC300T aluminum die casting machine best suited for?
The DC300T is an initial candidate for aluminum or magnesium projects whose total projected-area calculation, complete metal demand, die envelope, and process pressure fit the listed 3,000 kN clamp and a confirmed 50, 60, or 70 mm plunger package. It should be selected from the actual casting and die data rather than the 300 ton label alone.
Q02What are the main DC300T technical specifications?
Current published data lists 3,000 kN clamping force, 460 mm clamping stroke, 220 kN ejecting force, 105 mm ejection stroke, 250-700 mm die thickness, 900 x 900 mm platens, 580 x 580 mm tie-bar spacing, 370 kN injection force, 430 mm injection stroke, a 22 kW motor, and an approximate 11.5 ton machine weight.
Q03How should the 50, 60, or 70 mm plunger package be selected?
Compare complete shot weight and required intensification pressure together. The published 50, 60, and 70 mm packages increase aluminum capacity from 1.57 to 3.00 kg while listed intensification pressure decreases from 162 to 83 MPa. The largest plunger is therefore not automatically the safest process choice.
Q04How do I confirm whether 3,000 kN clamping force is enough?
Calculate the projected area of every cavity, runner, overflow, and pressure-exposed slide, multiply it by the documented cavity-pressure assumption, and apply the required operating margin. Check that result against 3,000 kN separately from shot weight, die fit, and maximum published casting area.
Q05When should I compare the DC238T, DC400T, or DC550T?
Compare the DC238T when it satisfies the same project with sufficient margin and a smaller footprint. Review the DC400T or DC550T when clamp demand, complete shot, die opening, platen area, die handling, automation, or maintenance clearance exceeds a documented DC300T boundary.
Q06What should a DC300T quotation and FAT plan confirm?
The quotation should identify the selected shot package, controls, hydraulic components, core-pull groups, die interfaces, furnace and dosing equipment, extraction and spraying automation, guarding, utilities, spares, documentation, packing, destination, and exclusions. The FAT plan should define safety checks, dry-cycle operation, pressure and speed verification, alarms, recipes, interfaces, and the evidence supplied with the machine.
