SALGRAVE Engraving Laminate

SALGRAVE laminates (similar to Vynalast & Cobex Engraving Laminate) are supplied in sheet form and consist of a blend of thermoplastics specifically formulated for the production of engraved signs, labels, control panels and nameplates.

 

Being a flexible thermoplastic, SALGRAVE has a high resistance to impact and can be locally bent to produce free standing signs or curved to fit a column.  Durable in service, SALGRAVE can be easily guillotined or cut into blanks without chipping or cracking.  When engraved swarf is not produced as an air-borne powder, eliminating dust hazard problems associated with thermosetting materials.

 

Special Effects and Finishes

 

Non-standard combinations of the three SALGRAVE finishes (Polished, Satin & Matt) can be produced in quantities ranging from as little as 8 sheets.

 

Triple or multiple colour laminates are also available. (colour will vary from those shown).

Properties

There are many properties that ensure SALGRAVE is the first choice engraving laminate:

•High impact strength: it will not crack or chip when preparing blanks.

•Can be cut by means of a circular saw or band saw or guillotined.

•All can be used internally or externally.

•Excellent fire rating

•Can be bent or curved without cracking.

•Swarf produced is not a dust hazard.

•Good chemical resistance

•Compatible with many adhesives and suitable for use with double sided adhesive tapes.

•Can be decorated by hot foil stamping.

Engraving Conditions

Any standard engraving machine used in conjunction with standard correct ground cutters will give good results when machining.

Tungsten carbide cutters will give a prolonged working life and require less grinding but they are not essential, as a good working life can be expected from high speed steel (HSS) cutters.  The advised clearance (cutting) angle is 40 degrees as this slows the swarf to escape.

 

The speed of the cutter is best established by the individual operator to suit his equipment and technique.  As a guide, a universal milling speed of 10,000 – 12,000 can be used for all widths.

 

SALGRAVE is a thermoplastic material and it will become soft and difficult to machine if allowed to over-heat.  If swarf is burring and using back into the cut the temperature and speed of engraving need to be reduced.  This problem is unlikely to occur if the correct speed is used with correctly ground standard cutters.

 

Where signs are screwed or riveted, the holes must be significantly larger to accommodate thermal expansion.
