Paper Testing and Core Compression Process


Core Compression Tester is an instrument used for testing the core collapsing strength. It has adjustable testing area to accommodate specimen of all sizes and shapes. Motor operated piston apply uniform pressure to crush the test sample. They have the maximum peak crush value recorded on digital load indicator. It is required to fulfill the basic need of quality control and development for manufacturers and users of Cone/ Core. An electronic instrument to measure and directly indicate the Compression Strength of Cone or Core.



The core compression strength of core pipes is the maximum compressive force that a test piece collapses under constant load. Pneumatically operated piston apply the pressure. Maximum pressure to crush the test sample recorded on a gauge with peak pointer. Has adjustable testing area to accommodate specimen sizes and shapes.


  • THICKNESS MICROMETER: This instrument is used for testing the core collapsing strength and has adjustable testing area to accommodate specimen sizes and shapes.
  • LABORATORY CRUSH TESTER: This instrument is used for accurate testing of paper, paperboard, solid fiberboard & corrugated board for RCT, ECT, CCT, CLT, FCT, PAT & CMT test and its components as well as performing compression test on all small packages.
  • STIFFNESS TESTER: The instruments is designed for evaluating stiffness and resilient qualities of paper, plastics, cardboard, light metallic sheets, foil and other flexible material having comparatively strong bending resistance.
  • PAPER CURL TESTER: This instrument is used to measure the Degree of curl when the paper sample exposed to water. This method applies the principle of wetting one side of the paper and determining the maximum curvature developed or the time required to reach maximum curvature.
  • BURSTING STRENGTH TESTER: For determining the bursting strength of paper and paperboard. Designed with pneumatic clamping of samples to avoid samples slippage under adjustable clamping force.  A test piece is clamped between two concentric plates, each having circular e by a rubber diaphragm, which is expanded by hydraulic pressure.

The Role of Wood Chip Classifier in Production of Good Quality Paper

Image
Pulp testing equipments are most critical aspects of paper making. The instruments that compromise this section of the catalogue is designed specifically for the analysis of different raw materials. These pulp testing instruments are used in research, development, alteration of pulp characteristics of optimizing paper and studying of board product properties before going into commercial production. Woodchipclassifier is a pulp testing instrument that is used for quick and reproducible determining the mean thickness and thickness distribution of wood chips intended for the production of chemical or mechanical pulps. A wood chip classifier has 5 standard screens and a fines pan. The light weight standard screens are made of stainless steel and aluminum for easy handling.   The light weight screens are mounted on the shaking table.     Wood chip classifiers are designed for rapid, reproducible and accurate classification of wood chips. A good quali...

Ring Crush Tester and Cobb Sizing Tester

The ring crush test (RCT) is an optimal instrument used to evaluate the ring crush resistance of a paper strip formed into a ring with some standard length and width. This test is performed to the strict standards of ISO 12192 and TAPPI T 822.  The ring crush tester is pretty similar to the test of short-span compression. The strength of the liner or fluting is determined both in the machine direction which placed perpendicular to it. It is mandatory that force application is placed perfectly to the specimen in the exact perpendicular while performing these tests. The outcome of this test highly relies on proper specimen preparation. Specimen and guides must be placed exactly parallel to ensure highly precise determination of ring crush strength. As the ring crush test gives information about how specimen buckling acts like be rather than crush behavior, it is being replaced by the short-span compression test these times. Ring Crush Test (RCT) with a professional...
