Finetech Engineering is a rectangle cutter manufacturer Maharashtra rubber and plastics testing labs rely on for accurate, repeatable rectangular specimen preparation. Every rectangle cutter we build is precision-ground and dimensionally verified against the governing specification before it leaves our Wagle Estate, Thane factory – manufacturer, not trader. If you have never had to source one before, what is a rectangle specimen cutter used for boils down to a single gap: whatever geometry a round disc genuinely cannot cut, whether that is a custom compression block or a general hardness strip.
A rectangle cutter for compression set is used specifically where a compression-set test rig calls for a rectangular block or slab specimen rather than the standard small circular disc – common for larger industrial rubber pads, mounts and gaskets tested in custom compression fixtures. For the standard small-button ASTM D395 disc specimen (29 mm or 13 mm diameter), Finetech’s Round Cutter remains the correct tool; the rectangle cutter addresses the rectangular-block configuration used in larger-scale or custom compression-set testing setups. Because our factory sits inside the state, Maharashtra labs asking how to cut rectangular compression set specimen blocks correctly can send us the fixture drawing and have a matched cutter back within days, not weeks.
As a rectangle cutter supplier Mumbai and rectangle cutter supplier Pune testing labs have used since 2023, we supply rectangle cutters built to precise, repeatable block dimensions for compression-set fixtures, and to relevant plastics flexural and general strip-specimen standards where required. For rectangle cutter price Maharashtra enquiries, contact us with your exact specimen dimension requirement and we will confirm a quotation – every cutter is dispatched from our Thane factory with the exact blade geometry your application specifies. On rectangular specimen cutter Maharashtra cost, being based here ourselves means there is no freight markup baked into the number – you are quoted directly off the block drawing, factory price.
Tip: Before ordering a rectangle cutter for compression-set testing, confirm your compression fixture’s exact specimen dimension requirement with your test engineer – unlike the standardised small-disc ASTM D395 specimen, rectangular block dimensions for larger custom compression rigs vary by fixture design and are not fixed by a single universal standard.
ASTM D395 specimen dimensions are defined primarily around circular disc specimens for the standard small-button compression set test, but Maharashtra labs working with larger industrial rubber components should understand both configurations. There is no fixed answer to what size a rectangular compression set block should be, since – unlike the standardised disc – block dimensions are set entirely by whichever custom fixture the compression rig was built around:
Configuration | Specimen Shape | Typical Dimensions | Cutter Used |
Standard small-button (Type 1) | Circular disc, stacked to thickness | 29 mm or 13 mm diameter discs, stacked to 12.5 ± 0.5 mm total thickness | Round Cutter |
O-ring compression set | Circular / annular | Per the O-ring’s actual cross-section dimensions | Round Cutter (custom sizing) |
Rectangular block (custom/larger fixtures) | Rectangular block or slab | Varies by compression fixture – confirm exact dimensions with your test rig specification | Rectangle Cutter |
The critical point in ASTM D395 specimen dimensions is that the standard, most widely referenced ASTM D395 test uses the circular disc configuration – if your specification simply cites “ASTM D395” without further detail, it most likely calls for the standard disc specimen and the Round Cutter. The rectangular block configuration is used specifically where a custom compression fixture, typically for larger rubber pads or mounts, has been designed around a rectangular geometry instead. Put simply, the difference between round cutter and rectangle cutter ASTM D395 specimens is not about what property gets measured – it is entirely about which fixture geometry your compression rig was designed around.
Note: Always confirm with your customer or test engineer which specimen geometry their compression set specification actually requires before ordering a cutter. Citing “ASTM D395” alone does not confirm rectangular block dimensions – the standard’s default and most common specimen is the circular disc.
Unlike compression set testing, Shore hardness testing (ASTM D2240) does not require a specific specimen shape – only adequate thickness (typically a minimum of 6 mm, achieved by stacking thinner sheets if needed) and enough flat surface area for the durometer’s indenter foot to seat properly. A rubber strip cutter for hardness test is therefore a genuinely accurate and common use for Finetech’s rectangle cutter: producing a flat rectangular strip specimen that gives Maharashtra rubber labs a consistent, adequately sized substrate for Shore A or Shore D hardness readings. Maharashtra QC benches often ask can a rectangle cutter be used for hardness testing on routine incoming batches, and the answer is yes – Shore hardness sets no fixed specimen shape, so a rectangular strip is just as valid as any other flat, adequately thick piece.
Why rectangular strips work well for hardness testing: the durometer indenter only needs a flat, sufficiently thick area to seat – a rectangular strip cut to a consistent size gives a repeatable, easy-to-handle specimen for routine batch QC.
Typical use: incoming rubber compound batch QC, where a quick hardness check on a rectangular strip cut from the sheet gives a fast pass/fail read before committing the batch to production.
Complementary to other specimen types: many Maharashtra labs prepare a rectangular hardness strip alongside dumbbell tensile and round compression-set specimens from the same sheet, covering three tests from one moulded slab. A rectangular block specimen cutter rubber compounders keep on the same bench as their dumbbell and round cutters is simply the third tool most complete Maharashtra rubber QC setups end up needing.

A rectangle cutter for compression set is used when a compression-set test rig calls for a rectangular block or slab specimen rather than the standard small circular disc - typically for larger industrial rubber pads, mounts and gaskets tested in custom compression fixtures. For the standard ASTM D395 small-button disc specimen (29 mm or 13 mm diameter), a Round Cutter is the correct tool; the rectangle cutter addresses the rectangular-block configuration specifically. A related question worth covering here: is rectangle cutter different from round cutter for every application? Not for hardness strips, where either shape works fine, but for compression set testing the two prepare specimens for genuinely different fixture types.
ASTM D395 specimen dimensions for the standard Type 1 test are circular discs, either 29 mm or 13 mm in diameter, stacked to a total thickness of 12.5 ± 0.5 mm. This is the default, most commonly referenced configuration when a specification simply cites 'ASTM D395.' Rectangular block specimens are used only in custom compression fixtures designed around that geometry - confirm which configuration your test rig requires before ordering a cutter.
Yes. A rubber strip cutter for hardness test preparation is a genuinely accurate use of the rectangle cutter - Shore hardness testing (ASTM D2240) does not require a specific specimen shape, only adequate thickness (typically a minimum of 6 mm) and sufficient flat area for the durometer's indenter foot to seat. A rectangular strip cut to a consistent size gives Maharashtra rubber labs a repeatable, easy-to-handle specimen for routine incoming-compound hardness QC.
