How to write an RFQ for a filling or packing machine

A checklist of the information a machine builder needs to quote a filling, capping or packing machine accurately and quickly.

Short answer: A useful RFQ states the product and its physical behaviour, the container or bag with dimensions, the fill amount and accuracy, the output per minute, the power supply in your factory, and which upstream and downstream steps the machine must connect to. Photos, drawings and product samples remove most guesswork.

1. The product

  • Name and form: liquid, paste, powder, granule, pieces or tablets
  • For liquids: viscosity or a comparison (“like yogurt”), foaming, temperature
  • For powders: whether it flows freely or is dusty and sticky
  • For pieces: size, shape and fragility

2. The package

  • Bottle, jar, can, cup, pouch or bag — with dimensions or a drawing
  • Closure: screw cap, pump, dropper, lug cap, foil seal
  • For bags: film material, width and bag length

3. Amount and accuracy

State the fill volume or weight range and the tolerance you need. Many of our source specifications list filling accuracy of about ±1%, depending on the product.

4. Output

Give the number of containers or bags per minute, and the working hours per day. If you are building a line, the slowest station sets the line speed.

5. Factory conditions

  • Voltage, phase and frequency (for example 220 V 1-phase 50 Hz or 380 V 3-phase)
  • Compressed air availability (many machines need 0.6–0.8 MPa)
  • Space available and ceiling height
  • HMI language required

6. What happens before and after the machine

Say whether the machine must connect to a washer, labeller, case packer or conveyor. This decides conveyor heights and directions.

7. Send it

Use the quote form, add machines to your quote list from any product page, or message us on WhatsApp with photos. We reply with questions or a quotation.

Questions and answers

Do I need to send product samples?

Not always for a first quotation, but samples let the machine be tested with your actual product before shipment.

What if I do not know the output I need?

Tell us your daily or monthly volume and working hours, and we can work out the per-minute speed.
