Match every equipment claim to the type of evidence that can actually support model identity, specification, intended design, installed configuration or process performance.
A brochure, technical proposal, design list, purchase record, operator-interface screen and machine photo answer different questions. Reliable equipment selection starts by defining the claim, then choosing evidence that proves that exact claim without extending it beyond its scope.

Working rule
Define the claim before choosing the evidence
01
Separate the kinds of equipment claims
Model identity, catalogue specification, intended design, purchased component, installed hardware, enabled control function and measured production performance are separate claims. Evidence for one claim should not be used as automatic proof of another.
Write the claim as a specific statement that can be checked.
Identify whether it concerns identity, design, installation, operation or measured result.
Keep unknown or unmeasured parts explicit rather than completing them by assumption.
02
Use the authoritative source for model specifications
For Hengfa standard machines, the verified final product brochure is the authority for public model names and catalogue specifications. Folder names, old sheets, manuals, screen labels and spoken descriptions can help locate evidence, but they do not replace the current authoritative record.
Match the model identity to the current authoritative brochure entry.
Quote only the specification fields that the authority states for that model.
Treat unlisted dimensions, speeds, accuracy and component brands as unconfirmed until separately verified.
03
Read design, purchase and installation evidence separately
A technical proposal describes an intended solution. A design list describes a planned configuration. A purchase record shows that an item was ordered or acquired. Only traceable inspection of the completed machine can confirm what is installed and how it is integrated.
Keep proposed, designed, purchased and installed states in separate fields or records.
Trace important installed components to the same machine or project being evaluated.
Verify integration, accessibility and operating state rather than checking component presence alone.
04
Treat operator-interface fields as control-entry evidence
A visible operator-interface field can show that the software provides a setting or display entry. It does not by itself prove that the related mechanism is installed, enabled, calibrated or used by the current machine configuration.
Link the field to a physical mechanism, signal or observed response on the same machine.
Confirm whether the entry is active, reserved, optional or unavailable in the current configuration.
Do not infer installed hardware, control sequence or performance from a screen label alone.
05
Do not turn factory values into a universal process window
A displayed or saved value belongs to a particular machine state, fixture, workpiece, film or foil and acceptance method. It can confirm that a control entry exists or that one setup used a value, but it cannot define a universal operating window for other materials or products.
Identify the exact material, workpiece, tooling and machine state associated with the value.
Separate a saved starting point from a validated production window.
Establish the current process by controlled trials and agreed sample acceptance.
06
Release claims with traceability and limits
A customer-facing equipment statement should identify what was verified, for which model or machine, by what source type and under what acceptance condition. A measured result should also state the material and test scope needed to understand where it applies.
Connect the statement to the model, machine or project that was actually verified.
State whether the evidence is authoritative, design intent, installed-state inspection or measured performance.
Record exclusions and open questions alongside the confirmed result.
Does an operator-interface menu prove that the machine has the corresponding function?
No. It proves that a control entry is visible. Confirm the related hardware, signal, enabled state and observed response on the same machine before claiming the function is installed and available.
Does a bill of materials prove the final installed configuration?
It records a design or planning state. Changes, substitutions and incomplete installation can occur. Verify the finished machine and trace important components to the same project before confirming the installed configuration.
Which source should be used for Hengfa standard-machine model specifications?
Use the verified final product brochure for public model identity and catalogue specifications. Other records may support mechanism or project context but should not override that authority.
