Choosing test equipment
Confirm the unit under test, the test items and the pressure and flow ranges before agreeing bench format and measurement points. Test equipment is configured per project: the same name can cover very different parameter ranges and instrumentation.
Hydraulic test benches
How do a multi-function bench and an impulse bench differ?
A multi-function bench checks hydraulic system and cylinder function and performance, including minimum starting pressure, internal leakage, pressure proof, leakage rate and pressure loss. An impulse bench applies cyclic loading to parts such as brake discs and valves to establish life. They serve different purposes and do not substitute for each other.
Share the drawing of the unit under test, the test programme, pressure and flow ranges, and the measurement points.

Field checks or bench validation?
Field inspection prioritises portability and speed: a rugged portable checker with built-in 1553B and ARINC429 bus interfaces and dual mains and on-aircraft power. Bench validation prioritises complete measurement and repeatable results: an online brake-system tester simulates wheel speed and pressure signals and identifies fault types. The two are usually used together.
Share the system under test, interface types, test items and the operating environment.
Explore inspection equipmentFuel and oil systems
Which oil condition indicators matter?
Look at particulate cleanliness class, water content and oil temperature. An oil condition monitoring system counts particles with a laser sensor and rates cleanliness to ISO 4406, NAS 1638 and SAE AS 4059, allowing component wear to be assessed and risk anticipated. Purification and preservation equipment restores oil to specification and keeps it protected.
Share the oil type, current cleanliness class, flow and operating temperature.
Explore fuel and oil systemsFrom requirement to bench: how test equipment is delivered
Test equipment generally proceeds project by project: confirm the unit under test and the test programme, agree bench format, pressure and flow ranges and instrumentation, then fabricate and assemble the mechanical, hydraulic, electrical and control systems, and finally commission and accept in-house. Stating the unit parameters and acceptance criteria early shortens the cycle more than discussing appearance first.
Industrial applications
Start with what the part must do. An appearance model, a repeatedly used fixture and a load-bearing component need different materials, validation and acceptance criteria.
| Application | What to establish | Review focus |
|---|---|---|
| Form and assembly prototypes | Appearance, clearance or actual assembly? | Identify critical mating dimensions and specify tolerances where fit matters. |
| Fixtures and locating parts | Contact surfaces, load direction, usage frequency and environment. | Review wear, stiffness and temperature requirements, contact surfaces and inspection methods. |
| Small-batch functional parts | Quantity, service life, acceptance criteria and repeat orders. | Compare total delivered cost, including finishing, inspection and batch consistency. |
A material name is not a performance specification
Nylon, metal or ceramic is only a starting point. Confirm the specific grade, process, post-processing condition and inspection requirements. Metal additive manufacturing may require support removal, heat treatment and machining; include these in the plan and lead time. [EOS]
When should you compare other manufacturing routes?
For simple shapes, available standard parts or sustained high-volume production, also compare off-the-shelf purchasing, machining or moulding. Compare the total cost and lead time of meeting the requirement, rather than the printing price alone.
Preparing a quote request
Clear requirements make a quote more useful. If the material is undecided, start with the intended use. If drawings are incomplete, identify the dimensions and requirements still to be confirmed.
- Use and environment
- What it does, what it contacts, how it is loaded, and any temperature, moisture or other conditions.
- Files and critical dimensions
- Available 3D files, dimensioned drawings, units and revision; flag mating dimensions, tolerances and cosmetic surfaces.
- Quantity and material requirements
- Initial quantity, expected repeat quantities and any required grade; state whether alternatives may be considered.
- Finishing and acceptance
- Machining, surface finishing or assembly requirements, and how delivered quality should be checked.
- Timing and delivery
- Desired arrival date, destination and budget range. International orders also require agreement on shipping and import arrangements.
Start by describing your requirements in the form. File formats and transfer arrangements can be agreed afterwards; the current form does not accept attachments.
Discuss an industrial projectFrequently asked questions
Can I inquire without a 3D model?
Yes. Buying an existing product usually does not require your own model. For a unit under test, a bench proposal or an industrial part, share drawings, intended use and critical dimensions first. Modelling feasibility and any separate fees require assessment.
Can dimensions and colours be changed?
You can request changes, subject to the design. Resizing may affect structure, detail and fit. Complex colour schemes or detailed painting need separate assessment. Pricing and production follow agreement on the specification.
What affects a 3D printing quote?
Material, geometry, size, quantity, supports, finishing, inspection and modelling can all affect the quote. Parts of the same weight may cost differently because their manufacturing and delivery requirements differ.
Can accuracy, load capacity or heat resistance be guaranteed upfront?
A process or material name alone is insufficient. Grade, geometry, build orientation, finishing and test conditions matter. Agree on validation and acceptance methods before ordering parts with critical functions.
How long will production and delivery take?
Existing designs, modified products and new developments have different timelines. Model approval, scheduling, quantity, finishing, transport and any inspection all contribute. Delivery arrangements are confirmed with the agreed specification.
