| 1 | Machine Type | Mechanical, hydraulic, rotary, or hybrid powder compaction press | The machine structure affects production speed, force control, tooling flexibility, and maintenance requirements. | Match the machine type with the powder, part geometry, required output, and allowable production cycle. |
| 2 | Nominal Pressing Force | Common industrial systems range from approximately 50 kN to more than 2,000 kN; laboratory presses may be smaller. | Higher force capacity supports larger parts, higher compaction pressure, and denser powder products. | Confirm rated force, usable force at the required stroke, and the permitted continuous-duty load. |
| 3 | Pressing Pressure | Many powder-compaction applications operate around 100–1,000 MPa, depending on material and product design. | Pressure directly influences green density, dimensional stability, strength, and defect formation. | Review the pressure calculation method, pressure uniformity, and material-specific test results. |
| 4 | Production Capacity | Output may range from several parts per minute for complex products to hundreds of parts per minute for simple rotary-pressed parts. | Actual productivity depends on tooling cavities, filling time, ejection, inspection, and material handling. | Request a cycle-time test using the intended powder and production tooling rather than relying only on rated speed. |
| 5 | Maximum Product Size | Determined by die diameter, filling depth, maximum tablet or component height, and available daylight. | A machine may have sufficient force but still be unsuitable if its die space or stroke cannot accommodate the part. | Check die-table dimensions, maximum tooling envelope, stroke length, and ejection distance. |
| 6 | Material Compatibility | Used for ceramic powders, powdered metals, hard metals, graphite, magnetic materials, pharmaceutical powders, and other formulated compounds. | Flowability, particle size, moisture, lubricants, abrasiveness, and compressibility vary significantly between powders. | Conduct trials with the actual powder and evaluate filling consistency, sticking, cracking, and ejection behavior. |
| 7 | Density and Force Control | Advanced presses may use servo control, closed-loop hydraulic control, multi-level filling, and independent punch adjustment. | Controlled force and displacement improve density distribution and reduce variation between batches. | Verify sensor resolution, repeatability, data logging, and the number of independently controlled axes. |
| 8 | Automation and Control System | Typical features include PLC control, touchscreen operation, recipe storage, alarm history, automatic lubrication, and production data recording. | Automation improves repeatability, operator safety, changeover efficiency, and traceability. | Confirm interface language, remote diagnostics, data-export format, cybersecurity controls, and spare-part availability. |
| 9 | Safety and Compliance | Important provisions include guarding, emergency stops, interlocks, overload protection, dust control, and documented risk assessment. | Powder dust and high mechanical forces create operational hazards if the machine is not properly protected. | Request applicable conformity documents, safety-circuit information, electrical schematics, and user manuals. |
| 10 | Service, Tooling, and Total Cost | Total ownership cost includes the press, dies and punches, installation, training, maintenance, utilities, spare parts, and downtime. | A lower purchase price may be offset by higher tooling costs, longer service response, or limited technical support. | Compare warranty terms, commissioning scope, tooling life, response time, consumables, and estimated five-year operating cost. |
