What to Send a Supplier for an Accurate Slitter Rewinder Quote

Slitter rewinders are configured machines. The same model can be quoted with different widths, shafts, knife systems, drives and automation, and the price changes with each. When an enquiry says only "we need a slitting machine for film", the supplier has to guess, and the guess is usually either too basic for your material or padded with options you do not need. The details below let the manufacturer propose the right configuration the first time.

Why incomplete enquiries cost you

• Prices that change later. A quote built on assumptions is revised once the real material and roll sizes come out, often after you have compared it against other offers.
• Wrong machine size. Too narrow or too small a diameter cannot be fixed after delivery. Too large means paying for capacity you never use.
• Missed options. Static elimination, differential shafts or a specific roller surface can be the difference between good and rejected rolls, and they are cheapest to include at the start.

You do not need every answer before you ask. Send what you know and say what is still open. A good supplier will ask about the rest before quoting.

Material

• Material family and structure, for example "BOPP, one side heat-sealable" or "PET 12 μm / PE 50 μm laminate".
• Thickness range: minimum, typical and maximum.
• Surface: printed, coated, metallized, adhesive, or optical grade inspected under strong light.
• Known behaviour: static, curl, stretch, dust, blocking.
• A material data sheet if you have one.

Parent roll

• Web width, and whether it varies between grades.
• Maximum outer diameter and weight.
• Core inner diameter and material (for example 3 inch or 6 inch, paper or steel).
• How rolls arrive at the machine today: crane, forklift, trolley or by hand.

Finished rolls and slit plan

• Slit widths and tolerances, and the narrowest width you will ever need.
• How many different slit patterns you run and how often they change per shift.
• Finished roll outer diameter, core size and winding direction (coating in or out).
• Any customer requirements on roll hardness, edge quality, splices or labelling.

A simple sketch of a typical slit pattern with widths and edge trim answers most of these at once.

Production and quality targets

• The speed you want and the lowest speed you could accept. Say which materials need to run fastest.
• Annual volume or hours per day the machine should run.
• The defects you most need to avoid: scratches, wrinkles, telescoping, dust, static.
• Which steps you want automated: knife positioning, unloading, shaft extraction, roll transport.
• Photos of current rolls or defects, and whether you can send sample rolls for a trial.

Site and delivery

• Country and destination port or site.
• Power supply: voltage, frequency and phases. Machines are built for the supply they will run on.
• Compressed air availability, floor space and any height or door-width limits for bringing the machine in.
• Safety or certification requirements that apply in your country.
• Target delivery date and whether you need installation and training on site.

A weak and a strong enquiry

The second enquiry is still short, and a manufacturer can already choose a model, a slitting method and the options worth discussing. The example is illustrative; send the figures for your own line.

To collect everything in one place, download the project requirement checklist (CSV, opens in Excel or Google Sheets), or go straight to the quote request form. Only five fields are required; the rest can follow.

Figures quoted for KINYUN machines come from the manufacturer's published specification. Everything else is general guidance; the configuration for your material is confirmed in writing in the formal quotation.
