Finetech Engineering is a rectangle cutter manufacturer Karnataka 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. Put simply, what is a rectangle specimen cutter used for on an electronics or auto-component line? Anything a round disc cutter cannot geometrically produce – custom compression blocks and general hardness strips alike.
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 – relevant for Karnataka’s electronics and auto-component sector when qualifying larger rubber grommet or mount components 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. If your team is unsure how to cut rectangular compression set specimen blocks for a grommet or mount fixture, the safest approach is always to work from the fixture’s own drawing rather than the standard disc dimensions.
As a rectangle cutter supplier Bangalore and rectangle cutter supplier Mysore 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 Karnataka 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. Most rectangular specimen cutter Karnataka cost enquiries we receive turn out to depend entirely on block dimensions rather than any fixed rate – the fastest way to a real number is sharing your fixture drawing with us directly.
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 Karnataka labs working with larger electronics and auto-component rubber parts should understand both configurations. If you have ever asked what size a rectangular compression set block should be for your specific fixture, the honest answer is that no fixed size exists – every custom rig sets its own dimensions:
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 electronics enclosure grommets or auto-component mounts, has been designed around a rectangular geometry instead. Put another way, the difference between round cutter and rectangle cutter ASTM D395 specimens is purely which fixture geometry your customer’s compression rig was built around, not a difference in what the test itself measures.
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 Karnataka rubber labs a consistent, adequately sized substrate for Shore A or Shore D hardness readings. The honest answer to ‘can a rectangle cutter be used for hardness testing’ comes down to one simple fact: Shore hardness has no fixed specimen shape requirement, so a rectangular strip qualifies as readily 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 for Karnataka’s electronics grommet/seal manufacturers and auto-component suppliers, where a quick hardness check on a rectangular strip gives a fast pass/fail read before committing the batch to production.
Complementary to other specimen types: many Karnataka 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. Most Karnataka electronics and auto QC benches that run a rectangular block specimen cutter rubber components also keep a dumbbell and round cutter close by, since the three together cover tensile, compression set and hardness from one sheet.
Whether your lab is in Peenya, Electronic City, KIADB Narsapura or Mysore, as a rectangle specimen cutter manufacturer Bangalore and laboratory equipment manufacturer Karnataka plants have sourced from since 2023, we dispatch rectangle cutters directly from our Wagle Estate, Thane factory – including testing instruments Peenya Industrial Area labs receive on scheduled delivery routes covering that cluster.
Standard | Specimen Configuration | Typical Dimensions | Application |
ASTM D395 (Type 1, standard) | Circular disc – Round Cutter | 29 mm or 13 mm diameter | Standard small-button compression set testing |
ASTM D395 (rectangular/custom) | Rectangular block – Rectangle Cutter | Fixture-specific, confirm before ordering | Larger electronics grommet and auto-component mount compression testing |
ISO 815 (Type A, standard) | Circular disc – Round Cutter | 13 mm diameter, 6.3 mm thick (typical) | Standard ISO compression set testing, common for electronics/auto OEM specifications |
ASTM D2240 (hardness) | Flat specimen, any shape – Rectangle Cutter suitable | Minimum ~6 mm thickness, adequate flat area | Shore A / Shore D hardness testing on incoming rubber compound |
Manufacturer, not a trader: Every rectangle cutter is designed, precision-ground and dimensionally verified at our Wagle Estate, Thane factory – not resold from another manufacturer.

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 - relevant for Karnataka's electronics and auto-component sector qualifying larger rubber grommets and mounts 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. That naturally raises the question: is rectangle cutter different from round cutter for every specimen type? No - for hardness strips either shape works, but for compression set testing the two are built for entirely different fixture geometries.
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 Karnataka rubber labs a repeatable, easy-to-handle specimen for routine incoming-compound hardness QC.
