Flexible Converting & Packaging Slitter Knife Supplier
Film · Nonwoven · PSA Tape · Label Converting Blades
Sureay Machinery manufactures precision circular slitter knives and specialty cutting tools for the flexible packaging, nonwoven fabric, and label converting industries. Our tooling is engineered for high-speed lines running at 150–600 m/min across BOPP, BOPET, CPP film, SMS medical nonwoven, pressure-sensitive tape, and adhesive-laminate substrates.
From matched top-and-bottom shear pairs for film and label slitting to DLC-coated blades for PSA tape lines, every Sureay converting knife is precision ground to ±0.002mm dimensional tolerance with optional TiN and DLC anti-adhesion coatings for pressure-sensitive tape and adhesive laminate applications.

[ The Industry Challenge ]
Speed Demands Precision.
At 400 m/min on a BOPP film line, a 0.005mm runout error per blade compounds across a 12-knife arbor, producing visible slit-width deviation, edge curl, and web tension spikes that drive unplanned downtime and customer complaints on the finished slit roll.
[ Sureay Engineered Solution ]
±0.002mm. Every Knife. Every Time.
Sureay converting knives are precision ground to ±0.002mm thickness tolerance and ≤0.02mm T.I.R. runout, with optional DLC coating for adhesive tape converting. Consistent geometry eliminates arbor wobble and reduces Mean Time Between Replacements by 40%.(40% longer MTBR)

OEM Process From Drawing To Delivery
Get In TouchA custom blade order moves through four clear steps — so you know what to send, what we confirm, and what gets checked before shipment.
Send Drawing Or Sample
Send your drawing, used sample, machine model, or key dimensions. We review the application, blade geometry, material being cut, and any known fit or wear issues from your current supplier.
Engineering Review
Our engineers confirm steel grade, heat treatment direction, tolerance target, edge profile, and all OEM-fit details. Any open questions are resolved before quotation or production approval is issued.
Machining And Hardening
The blade moves into CNC machining, vacuum heat treatment, and precision grinding in a controlled sequence. Each stage is tracked against the approved specification to prevent distortion and geometry drift.
Inspection And Shipment
Final dimensions, hardness, and edge condition are verified against specification before dispatch. The order is packed and shipped with the required inspection records, and material certification documents.
