Projected area and clamp
Calculate the total area exposed to cavity pressure, including runners, overflows, and relevant slides. Record the pressure assumption and operating margin.
DC238T / Standard cold chamber platform
238 Ton Aluminum Cold Chamber Die Casting Machine
The DC238T is a 2,380 kN cold chamber die casting machine for initial screening of aluminum and magnesium projects. Its three listed plunger packages must be selected together with projected area, required pressure, complete shot demand, die envelope, and production-cell scope.

Four-gate model approval
Can the DC238T fit your casting and die?
A model is suitable only when it passes every gate with the project assumptions documented. A successful shot-weight check does not prove clamp or die fit.
Direct answer: shortlist the DC238T when the calculated clamp demand stays within 2,380 kN with the agreed margin, the complete shot fits one confirmed plunger package, the die clears the 530 x 530 mm opening and 200-670 mm thickness range, and the required injection and cell scope can be supplied.
Complete metal demand
Add all cavities, runners, biscuit, overflows, and process allowance. Compare the result with the selected aluminum or magnesium shot package.
Die envelope and movement
Confirm die width, height, thickness, weight, mounting, opening, ejection, core pulls, lifting route, and service access against the actual layout.
Injection and cell scope
Match pressure, speed stages, plunger, shot sleeve, furnace, ladler, sprayer, extractor, trimming, cooling, safety, and automation interfaces.

System inspection file
Three DC238T areas to convert into quotation checkpoints
The images are cleaned configuration references based on supplied and published machine visuals. They contain no Chinese product text and do not define included component brands.
01
Dual-proportional hydraulic control
Confirm how pressure and speed settings are controlled, which hydraulic brands are quoted, how oil temperature is managed, and which diagnostic information is available to maintenance staff.
02
Independent injection and intensification accumulators
The published configuration describes separate high-speed and intensification accumulators. Ask the technical agreement to define injection stages, pressure response, gauges, safety checks, and acceptance method.
03
Hydraulic manifold and pressure-control package
Record component brands, core-pull groups, filtration, oil specification, service access, recommended spares, and the documents supplied for troubleshooting and preventive maintenance.
Published system description
Translate feature claims into acceptance evidence
The current product description outlines the intended machine systems. Procurement should turn each statement into an agreed configuration, inspection item, or document deliverable.
Review the machine RFQ checklist ->Five-point double-toggle clamping
Confirm tie-bar material and treatment, multistage clamp settings, low-pressure die protection, balanced hydraulic ejection, centralized lubrication alarms, and platen cooling-water connections.
Multistage shot and intensification
Confirm separate accumulator functions, electro-proportional slow-shot control, selectable injection stages, published speed range, pressure response, injection position, and repeatability test method.
Core-pull and regeneration circuits
Define standard and optional core-pull groups, differential regeneration circuit, filtration, oil grade, operating temperature, component makes, spares, and safe pressure-release procedure.
Recipes, language, and integration
Confirm controller and HMI make, language, recipe capacity, data access, voltage and frequency, cabinet cooling, safety circuit, automation I/O, remote support, and electrical documentation.
Quotation boundary
Define the complete cold chamber cell, not only the base machine
The same DC238T model can produce very different quotations when the shot-end package, holding furnace, ladler, sprayer, extractor, conveyor, trim equipment, release-agent system, cooling, guarding, documentation, testing, and service scope are not aligned.
- 01Part and die evidence
Drawings, alloy, complete shot, projected area, cavity count, die envelope, weight, mounting, ejection, core pulls, and quality targets.
- 02Production assumptions
Target cycle, annual volume, shifts, OEE assumptions, scrap target, automation level, changeover needs, and inspection plan.
- 03Factory interfaces
Layout, floor loading, lifting and die handling, voltage, cooling, compressed air, extraction, safety standard, and maintenance clearance.
- 04Commercial deliverables
Included equipment, options, startup and operating spares, FAT, training, manuals, packing, destination terms, warranty, service, and exclusions.
DC238T buyer answers
Questions to close before technical approval
These answers help purchasing, tooling, and process teams separate initial model screening from final engineering confirmation.
01What is the DC238T cold chamber die casting machine best suited for?
The DC238T is an initial candidate for aluminum or magnesium castings whose projected-area calculation, complete shot demand, and die envelope fit the listed 2,380 kN clamp, 530 x 530 mm tie-bar spacing, 200-670 mm die-thickness range, and selected 50, 60, or 70 mm plunger package. Part weight or nominal tonnage alone cannot confirm the model.
02What are the main DC238T technical specifications?
The current published data lists 2,380 kN clamping force, 400 mm clamping stroke, 170 kN ejecting force, 100 mm ejection stroke, 820 x 820 mm platen size, 530 x 530 mm tie-bar spacing, 300 kN injection force, 390 mm injection stroke, 15 kW motor power, and an approximate 8.5 ton machine weight.
03How do I choose the 50, 60, or 70 mm DC238T plunger package?
Match the complete metal demand and required intensification pressure together. The published combinations pair 50, 60, and 70 mm plungers with different aluminum and magnesium shot weights, casting pressures, and casting areas. A larger plunger raises shot capacity but lowers the listed intensification pressure, so it should not be selected from weight alone.
04How do I check whether 2,380 kN clamping force is enough?
Calculate the total projected area of all cavities, runners, overflows, and slides exposed to cavity pressure, multiply by the agreed cavity-pressure assumption, and apply the required operating margin. Compare that result with 2,380 kN separately from the shot-weight and die-fit checks.
05When should I compare the DC180T, DC300T, or DC400T?
Compare the DC180T when the project fits its smaller clamp, die opening, and shot package. Move to the DC300T or DC400T when the projected-area calculation, complete shot, die clearance, injection requirement, automation, or service layout crosses a documented DC238T limit.
06What information is needed for a useful DC238T quotation?
Send the alloy, part drawing, net casting and runner weight, projected area, cavity count, die dimensions and weight, target cycle, annual quantity, voltage, destination, automation, furnace and dosing method, safety standard, documentation, testing, packing, and spare-parts requirements. Final signed quotation and technical documents take precedence over web data and reference images.
