Finetech Engineering is a rectangle cutter manufacturer Andhra Pradesh 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. Whether the enquiry comes from a Vizag pharma line or a Vijayawada auto-parts supplier, what is a rectangle specimen cutter used for always comes back to the same gap: work a round disc geometrically cannot fill, from custom compression blocks to general hardness strips.
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 Andhra Pradesh’s pharma packaging sector when qualifying larger rubber gasket or seal 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. Whether the fixture belongs to a pharma closure line or an auto rubber mount rig, how to cut rectangular compression set specimen blocks correctly always starts the same way – with the fixture’s own drawing, never the round-disc dimensions.
As a rectangle cutter supplier Visakhapatnam and rectangle cutter supplier Vijayawada 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 Andhra Pradesh 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 Andhra Pradesh cost queries we field settle once we see the actual block drawing – pricing tracks the specimen geometry itself, not a fixed product code.
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 Andhra Pradesh labs working with larger pharma packaging or industrial rubber components should understand both configurations. Buyers regularly want a fixed figure for what size a rectangular compression set block should measure, but the honest answer is that Andhra Pradesh’s pharma and auto fixtures each set their own dimensions – there is no universal block size to quote:
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 closures or gaskets, has been designed around a rectangular geometry instead. Framed differently, the difference between round cutter and rectangle cutter ASTM D395 specimens has nothing to do with the property being measured and everything to do with which fixture geometry a given pharma or auto customer designed.
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 Andhra Pradesh rubber labs a consistent, adequately sized substrate for Shore A or Shore D hardness readings. Pharma and auto QC teams alike sometimes ask can a rectangle cutter be used for hardness testing on their incoming rubber, and the answer holds regardless of industry: Shore hardness sets no specimen shape rule, so a rectangular strip serves as well as any other flat, adequately thick piece.
Whether your lab is in Visakhapatnam, Vijayawada, Satyavedu or Naidupeta, as a rectangle specimen cutter manufacturer Visakhapatnam and laboratory equipment manufacturer Andhra Pradesh plants have sourced from since 2023, we dispatch rectangle cutters directly from our Wagle Estate, Thane factory – including testing instruments APSEZ Vizag 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 pharma closure/gasket and industrial rubber compression testing |
ISO 815 (Type A, standard) | Circular disc – Round Cutter | 13 mm diameter, 6.3 mm thick (typical) | Standard ISO compression set testing |
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.
ISO 9001 certified: Our manufacturing is ISO 9001:2015 certified and our equipment is CE marked.
NABL-traceable dimensional certification: Cutter dimensions verified and certified against the governing specification, supporting NABL-accredited lab audits and pharma regulatory documentation requirements.
Custom dimensions for compression fixtures: Since rectangular compression-set block dimensions vary by fixture design, we build cutters matched to your exact specification rather than a generic size. Whether the order comes from a pharma closure line or an auto mount supplier, a compression set specimen cutter rectangular fixtures require is ground to that specific drawing here – never pulled from generic stock.

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 Andhra Pradesh's pharma packaging sector qualifying larger rubber closures and gaskets 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 answering directly: is rectangle cutter different from round cutter in practice? For hardness work, not really - either shape suffices. For compression set testing, yes - each prepares specimens for a genuinely different fixture type.
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 Andhra Pradesh rubber labs a repeatable, easy-to-handle specimen for routine incoming-compound hardness QC.
We are a manufacturer. As a rectangle specimen cutter manufacturer Andhra Pradesh and rectangle specimen cutter manufacturer India testing labs have used since 2023, every cutter is designed, precision-ground and dimensionally verified in-house at our Wagle Estate, Thane facility - not purchased from another manufacturer and resold.
