How to prepare a custom test equipment case RFQ.
A useful quotation needs more than the outside dimensions of the instrument. Define the complete kit, field workflow, carrying load and approval criteria before requesting a sample.
CONCEPT DEVELOPMENT EXAMPLE01Define the full kit
02Choose construction by use
03Approve with real load
04Freeze the production specification
Information to send
Start with five groups of inputs.
Photos and rough dimensions are enough for an initial review. Final fit approval may still require an equipment sample when tolerances or access points are critical.
01
Equipment
Overall dimensions, weight, fragile areas, connectors and controls.
02
Full kit
Probes, cables, chargers, adapters, manuals and consumables that travel with it.
03
Field use
Car, aircraft, service van, indoor plant, construction site or distributor demo.
04
Carrying method
Hand carry, shoulder strap, trolley attachment or hands-free operation.
05
Commercial plan
First order, annual volume, target launch date, branding and packaging.
Measurement checklist
Measure the use case, not only the device.
Lay out everything that must travel in the case and photograph the complete kit before deciding the internal arrangement.
ItemWhat to provideWhy it matters
Main deviceLength × width × height, including guards, knobs and protrusionsDo not measure only the rectangular body.
AccessoriesIndividual size or one arranged-kit photo with a scaleIdentify items that must not rub against the device.
WeightLoaded weight, not only the empty instrumentThis affects handles, shoulder points and reinforcement.
AccessControls, screens, ports or ventilation needed while in the caseMark them directly on a photo where possible.
Fit toleranceAreas requiring close fit versus flexible storage spaceA physical sample is recommended for tight tolerances.
Construction decisions
Translate the field environment into a case specification.
Padding
Decide fromEquipment value, impact risk and acceptable case weight
Foam type and thickness should be confirmed on the approved sample.Structure
Decide fromSoft, semi-rigid or divider-supported
PP board, PE sheet or removable dividers may add shape.Organization
Decide fromFast field access versus maximum protection
Use pockets, elastic loops, dividers or separate removable pouches.Hardware
Decide fromLoad, opening frequency and field environment
Specify zipper path, buckles, hooks and shoulder hardware.These are RFQ starting points—not fixed performance claims. Materials and construction must be confirmed against the application and approved sample.
Sample approval
Load the real kit before signing off.
A prototype should be evaluated as a working system. Photograph any requested change and identify the exact pocket, seam or dimension affected.
01The complete equipment kit fits without forced loading.
02Fragile surfaces and connectors do not contact loose accessories.
03Handles and shoulder points feel balanced at the real loaded weight.
04The zipper opens without scraping the equipment or trapping cables.
05All pockets, windows, labels and operating openings are in the correct position.
06Finished dimensions, materials, colours and packaging are recorded for bulk production.
Avoid rework
Four common RFQ mistakes.
Quoting from one outside dimension
The supplier cannot see knobs, cables, probes or the intended loading sequence.
Approving an empty sample
A case that looks balanced when empty may fail when the full kit is carried.
Using vague material names
Terms such as “Oxford fabric” do not define coating, weight, colour or performance.
Ignoring repeat orders
The approved pattern, component list and packing method should be recorded for consistency.
Copy this structure
A short RFQ is enough when the inputs are specific.

Request an initial review
Send the equipment link, full-kit photo and expected quantity.
We can review whether the project fits sewn soft-case construction and identify the information still needed before sampling.
