Slitting & Die-Cutting
Slitting is where a good master roll becomes either a productive roll or a line-side headache. Width tolerance, edge quality, winding tension and core alignment decide whether your operators spend their shift wrapping or re-threading.
We slit and die-cut in-house on the same site as the coating line, so the finished format can be adjusted without a converter in between.
Converting formats
| Format | Typical use | What to specify |
|---|---|---|
| Slit rolls | Manual and semi-automatic harness wrapping | Finished width, length, core inner diameter, winding direction |
| Log rolls / spools | High-volume manual wrapping | Log length, core type, whether the roll is handled or mounted |
| Die-cut pieces | Automated assembly, tabs and electrical insulation parts | Drawing of the shape, part quantity per sheet or reel, tolerances |
| Sheeted pieces | Hand-applied insulation and masking | Piece size, quantity per pack, whether a release liner is needed |
Points worth specifying early
| Point | Why it matters |
|---|---|
| Width tolerance | A tolerance that is too tight adds cost; one that is too loose causes misalignment and waste. |
| Core diameter | Must match your dispenser or winder — 76 mm (3") and 32 mm are the common standards. |
| Winding direction | Adhesive-in or adhesive-out changes how the roll is mounted. |
| Roll length | Longer rolls reduce operator changeovers but must not exceed handling weight. |
| Liner | Die-cut parts and sheets often need a release liner; rolls usually do not. |
