Choose a cold chamber die casting machine by matching the casting process, clamping force, injection capability, mold dimensions and complete production cycle. Tonnage is a starting point, but it does not tell you whether an existing die will fit or whether the shot unit can meet your filling requirements.
For a distributor evaluating a customer project, the most useful first step is to collect the part and mold information before requesting a machine recommendation. A quotation based only on part weight or a preferred tonnage can leave important requirements unresolved.
This guide explains what to compare across the 180–900T range. It uses the Xiongyi HII supplied for this guide as a worked specification reference, including an example of why a 650T and a 700T machine can have similar shot capacities but different mold space. The same comparison method can help buyers evaluate other machines with equivalent, verified specifications.
For aluminum high-pressure die casting projects, a cold chamber machine is a common starting point. Confirm the actual alloy grade rather than describing the material simply as “aluminum.” If the project involves magnesium or another alloy, ask the supplier to confirm the appropriate process and supporting equipment instead of assuming that an aluminum configuration is interchangeable.
Record the part’s dimensions, minimum wall sections, critical tolerances, surface requirements and any leak-test or internal-quality requirements. These details help define the filling process, mold arrangement and inspection method.
Provide a drawing and, when available, a 3D model. A photograph can support an initial discussion, but it cannot replace the dimensions and geometry needed for a technical review.
A finished casting’s weight is not the same as the metal injected during one cycle. The complete shot must account for all cavities and the associated runner, overflow and biscuit material.
For an existing production die, provide the established complete-shot weight and relevant process settings. For a new die, have the tooling engineer estimate the complete shot from the proposed design. Do not choose a machine by comparing one finished part directly with the largest kilogram value in a brochure.
State the number of acceptable parts needed per shift, the planned operating hours and the number of cavities. Also identify whether the project is a new line, a replacement machine or an expansion using existing tooling.
These distinctions matter: a replacement must accommodate established interfaces and dies, while a new line allows more freedom to coordinate the mold, machine and automation from the beginning.
The table below summarizes selected data from the April 2026 HII brochure supplied for this guide. It is a comparison aid, not a confirmation of current availability or the final specification of a quoted machine.
Model | Brochure tonnage class | Clamping force (kN) | Clear distance between tie bars (mm) | Die thickness range (mm) | Listed aluminum shot weights by available plunger option (kg) |
|---|---|---|---|---|---|
DM180HII | 180T | 1,800 | 460 × 460 | 200–600 | 1.2 / 1.8 |
DM300HII | 300T | 3,000 | 570 × 570 | 250–700 | 1.5 / 2.1 / 2.9 |
DM400HII | 400T | 4,000 | 650 × 650 | 300–750 | 2.7 / 3.6 / 4.8 |
DM500HII | 500T | 5,000 | 750 × 750 | 350–850 | 4.1 / 5.4 / 6.9 |
DM650HII | 650T | 6,500 | 780 × 780 | 350–900 | 4.6 / 6.1 / 7.7 |
DM700HII | 700T | 7,000 | 850 × 850 | 350–900 | 4.6 / 6.1 / 7.7 |
DM800HII | 800T | 8,000 | 930 × 930 | 400–950 | 7.1 / 9.0 / 11.1 |
DM900HII | 900T | 9,000 | 960 × 960 | 400–950 | 7.1 / 9.0 / 11.1 |
The T labels follow the brochure’s commercial naming. Use the stated kN ratings for engineering calculations rather than assuming the model number is an exact metric-ton-force conversion. Listed shot weights are reference values associated with particular plunger options; they are not guaranteed finished-part weights or recommended operating limits for every mold.
In this brochure, both models list 600 kN injection force, 70/80/90 mm plunger options and the same corresponding aluminum shot weights. Their clamping force and tie-bar spacing differ.
The DM700HII lists 850 × 850 mm between the tie bars, compared with 780 × 780 mm for the DM650HII. This difference can matter when reviewing the die’s installation envelope. It does not, by itself, establish that a particular die fits: mounting, die thickness, extraction clearance and other interfaces still require checking.
The larger tonnage class does not provide a larger listed shot weight in this comparison. A buyer seeking more shot capacity should review the injection unit and complete-shot requirements rather than assume that the next model number solves the problem.
Clamping-force screening concerns the force tending to separate the die halves. It is not determined by casting weight alone. The tooling and process team should establish the relevant projected area at the parting plane, including the applicable cavities and feed-system features, and an appropriate pressure assumption.
Do not substitute the hydraulic system pressure for cavity pressure. Likewise, a machine’s maximum listed casting pressure is not automatically the pressure that should be applied uniformly across a proposed casting for every selection calculation.
For a uniform assumed pressure, the dimensional relationship can be written as:
Required screening force (kN) = projected area (cm²) × assumed cavity pressure (MPa) × 0.1 × selected margin factor.
For illustration only, 500 cm², 60 MPa and a selected margin factor of 1.3 give:
500 × 60 × 0.1 × 1.3 = 3,900 kN.
These are hypothetical inputs, not recommended process settings or a universal margin. A machine rated at 4,000 kN would only pass this simplified numerical screen; it would still require a complete engineering review. The process team must assess the actual pressure assumptions, geometry, mechanical loading and remaining operating margin before approving a machine.
A machine’s plunger diameter, shot weight and available casting pressure must be considered together. Selecting the largest shot-weight value and the highest pressure value from different plunger options produces a combination the brochure may not offer.
For example, the supplied DM400HII table pairs 60/70/80 mm plungers with aluminum shot weights of 2.7/3.6/4.8 kg and casting pressures of 145/106/81 MPa, respectively. The 4.8 kg value and the 145 MPa value belong to different options.
For the proposed plunger, ask the supplier to verify the usable shot volume, shot-sleeve filling conditions, stroke requirements and pressure capability against the mold and process. Avoid applying one generic sleeve-fill percentage to every installation.
A maximum dry-shot speed does not establish the speed available under the resistance of a particular mold. Request application-specific confirmation of the filling capability and the control functions included in the quotation.
Discuss the slow-to-fast shot transition, pressure build-up and repeatability using the proposed casting requirements. Where relevant, ask for a review of the machine’s P-Q² capability against the tooling demand. Peak brochure figures alone do not demonstrate a suitable operating window.
Compare the complete die drawing with the machine’s platen and installation drawings. Include external fittings, slides, connectors and any equipment that affects loading or movement.
Check | What the buyer should provide or confirm |
|---|---|
Tie-bar clearance | Die envelope and intended loading route |
Die thickness | Closed-die height against the machine’s permitted range |
Mounting | Platen holes, slots, fastening arrangement and contact requirements |
Opening clearance | Space needed for the casting, runners and extraction equipment |
Ejection | Required force, stroke, rod arrangement and sequence |
Core pulls | Number of circuits, movement sequence and interface requirements |
Shot interface | Shot position and sleeve/flange compatibility |
Handling and support | Die weight, lifting method and permitted machine loading |
A die may fit between the tie bars yet leave insufficient clearance for extraction or core movement. Review the sequence from closing through injection, opening, ejection and removal, including the equipment that moves into the machine area.
For a replacement project, provide the existing machine’s relevant drawings and interface information. Similar tonnage does not establish interchangeability.
The supplied brochure identifies the asynchronous motor system as standard and the servo motor system as optional. Intelligent online quality control is also marked as optional. The configuration table lists real-time speed control as an option for DM500HII through DM900HII; it does not list that option for the three smaller models.
Treat these as statements about this brochure version. Ask for a configuration schedule for the exact machine being offered, including any changes or special arrangements.
Ask separately whether the quoted system displays curves, records data, compares parameters against limits, generates alarms or actively adjusts injection behavior. A curve display should not be interpreted as proof that every closed-loop control function is included.
If comparing conventional and servo configurations, request energy measurements under a stated duty cycle and production condition. Identify whether the measurement covers the machine only or the complete cell, including furnaces and cooling. Motor nameplate power is not a measured energy cost per acceptable casting.
Base output estimates on the complete operating sequence, including metal dosing, die movement, filling, solidification, spraying and extraction. Some operations can overlap; others become bottlenecks. Ask for a cycle breakdown rather than adding unrelated brochure minimum times.
Separate theoretical output from expected acceptable output. State the assumed cycle time, cavity count, operating hours, availability and yield so that a distributor and end customer can assess the same assumptions.
Confirm whether the offer includes only the machine or also the furnace, ladling equipment, sprayer, extractor, temperature-control equipment, trimming and transfer systems. Identify who is responsible for interfaces, installation and commissioning.
Peripheral interface availability helps integration, but it does not establish compatibility with every robot or auxiliary device. A proposed layout should also allow maintenance access, die changes and the necessary factory utilities.
Agree on the test die, alloy, equipment configuration, inspection requirements and production conditions. Define which checks will be performed before shipment and which require commissioning at the destination.
Record how cycle time, sample quality and machine functions will be evaluated. A brief demonstration with an unrelated mold cannot establish performance for every customer product.
For an overseas distributor, the support arrangement is part of the purchase decision. Confirm who handles installation, operator training, first-line troubleshooting, replacement parts and escalation to the equipment manufacturer.
Request the relevant documentation and an initial spare-parts recommendation. Define the scope of any warranty and service commitment in the actual quotation or agreement rather than relying on general promotional wording.
Send the information available now and identify what still needs to be developed. Missing mold data is not a reason to stop an early discussion, but it should remain visible as an open selection requirement.

Request a machine-selection review.
No. Part weight is only one input. The complete shot, projected area, pressure requirements, mold dimensions and production target must also be reviewed.
No. In the supplied HII comparison, the 700T model has greater clamping force and tie-bar spacing, while the listed shot-weight options match the 650T model. The appropriate choice depends on the job requirements.
No. A complete shot includes metal beyond the finished casting, and each listed capacity corresponds to a particular plunger option. The usable operating conditions require confirmation.
Possibly, but the die and machine drawings must be checked together. Review mounting, die thickness, opening and ejection clearances, shot position and core-pull interfaces before ordering.
Do not assume they are. The supplied brochure identifies servo drive as optional and lists real-time speed control options only for certain models. Obtain the configuration schedule for the actual quotation.
Start with the drawing, alloy, quality requirements and target output. The supplier and tooling engineer can develop the missing inputs before the final machine specification is approved.
Technical data reference: HII brochure supplied for this guide, technical-data and configuration tables. Confirm all model names, specifications and options against the current quotation and approved technical agreement.
