Small-Diameter Circular Knitting Machine RFQ: Size Range, Samples and Output

Small-diameter RFQ dossier

Send boundary products before asking for a price

A request for a small knitting machine is incomplete until the supplier knows what the smallest and largest products are, how their tubes or zones are formed, and which operations remain after knitting. The RFQ should make those boundaries visible before diameter, gauge or output is negotiated.

Attach finished and opened samples, a size table and a yarn package from likely production supply. Mark the garment or tube direction, stretch direction, seams, separation points, pattern areas and finishing route. If a sample is confidential, replace it with a controlled drawing and measurable swatch rather than a generic product name.

Ask every supplier to identify the exact offered model and installed configuration. Official ranges show that small or body-size machines differ in diameter, gauge, feeds, needle beds and selection. A broad family name is not a delivery specification.

Define the size family from finished measurements

List circumference, length, opening dimensions and zone position for every size, then highlight the smallest, largest and least-stretch styles. State whether size changes require a cylinder, needle set, program, yarn or finishing adjustment.

Do not derive the complete range from one comfortable middle size. Trial boundary garments after relaxation or finishing and record where the proposed configuration stops being repeatable.

Draw knitting and make-up responsibility

Show which portions are continuous tube, electronically selected, separated, cut, linked, sewn or closed. Include cuffs, crowns, gussets, leg or arm openings and decoration. This prevents the word seamless from hiding downstream labour.

For each transition, identify required yarns and feeder or selector actions. Ask the supplier to mark unsupported actions rather than improvising a substitute structure during the demonstration.

Quote output as accepted products under a named route

Choose a timed run with production yarn and record running minutes, pieces or length, stops, manual interventions, separation waste and rejected items. Add make-up time when the commercial unit is a finished product.

Output from a plain tube cannot forecast a programmed style with frequent yarn changes or zones. Require separate results for materially different boundary products and keep catalogue values labelled as screening information.

Put programs, change parts, training and spares into the offer

List every cylinder, needle or sinker set, yarn device, selector, program tool, take-down option and make-up accessory included. State who creates the first patterns and which editable files the buyer receives.

Build training around loading the approved program, threading production yarn, changing a defined size, diagnosing one common stop and reproducing the accepted sample. Link the initial spare-parts list to the installed build rather than accepting a generic kit.

Small-diameter RFQ questions

Which sample should be sent first?

Send the style most likely to expose size, yarn, pattern or make-up limits, plus a normal commercial reference.

Can diameter be selected from finished circumference alone?

No. Needle count, gauge, structure, stretch, yarn and finishing also affect the relationship. Confirm with the exact model and sample.

Should output be pieces per hour or kilograms per hour?

Use the commercial unit that the mill sells and define its acceptance. For garments or components, pieces plus make-up work may be more useful.

What software should appear in the quotation?

List programming tools, licenses, interfaces, editable formats, training and who owns pattern revisions. Do not assume they are standard.

When is the RFQ ready to price?

When every supplier can identify the same boundary products, configuration, delivery scope and acceptance method without filling gaps by assumption.

Conclusion

A strong small-diameter RFQ reads like a production handover in advance. It ties sizes to finished measurements, construction to named machine actions, output to accepted boundary products and price to a visible delivery scope. That makes competing offers comparable and reduces change orders after the machine is built.
