The Finetech Engineering Rectangle Specimen Cutter India is a precision parallel-blade die used to cut uniform rectangular test strips from flat sheets of rubber, plastic film, paper, paperboard, textile, and flexible packaging materials. As a specialist rectangular die cutter for rubber plastic and paper manufacturer, we produce this cutter in multiple widths to serve a broader range of testing standards than any other specimen geometry.
Unlike dumbbell cutters (which produce shaped specimens with a narrow gauge section), our rectangle specimen cutter India produces specimens with a constant width across their full length – a straight-sided strip. Rectangular strips are the most versatile specimen shape in material testing, specified across rubber tensile and fatigue testing (ASTM D412, D4482), plastic film testing (ASTM D882), paper tensile testing (ISO 1924, TAPPI T494), and textile testing (ASTM D5035, ISO 13934-1).
The key to reliable results is consistent strip width. Even a 0.5mm variation across the length of the strip introduces significant error in calculated stress values because the cross-sectional area changes. As a strip cutter for compression set testing India and general strip-cutting specialist, Finetech Engineering grinds every rectangular die cutter for rubber plastic to ±0.1mm parallelism – ensuring every strip is exactly the specified width from end to end.

Yes. Finetech Engineering provides NABL-traceable dimensional certification verifying the cutting width and edge parallelism of each strip cutter.
Standard cutting lengths are 150 mm, 200 mm, and 250 mm. Custom lengths are available on request. The cutting length refers to the length of the cutter die itself — the specimen strip produced will be the same length as the cutter (minus a few mm at each end where the blade curves).
Yes. We manufacture multi-lane strip cutters (e.g., a cutter that produces 5 or 10 parallel strips in a single press stroke). This is commonly requested by paper mills and film testing labs that need to cut large numbers of identical strips for batch testing. Contact us with the number of strips and the width, and we will design a multi-strip cutter for your application.
