Office stationery testing equipment

Brief Introduction:Ferrous metals, non-ferrous metals, IC wafers, surface coatings, laminated metals; Glass, ceramics, agate, gemstones, etc. Hardness testing of the depth and gradient of the carbonized layer and the quenched hardened layer.

Brief Introduction:Fix the movable pencil with the tip facing down on the pen holder respectively, adjust the distance of the indenter, adjust the fixture, start the instrument, and conduct a fatigue test on the movable pencil at a speed of 100 times per minute.

Brief Introduction:This machine is specifically designed to test the tensile strength of the pen tip.

Brief Introduction:Test the sharpening ability of the pencil sharpener.

Brief Introduction:This machine is used to detect the magnitude of the force acting on the tips of various colored pencil leads.

Brief Introduction:This machine is suitable for testing the bending value of the pen.

Brief Introduction:The word erasure rate tester is composed of two machines, namely the colored paper making machine and the eraser machine. First, a high-grade HB pencil sharpened to 0.6MM was used to contact the test paper fixed on the drum of the test paper making machine at a 75-degree Angle under a load of 0.3kgf. Lines were drawn on the test paper at a speed of 310±10cm/min. The test paper was removed and fixed on the eraser machine. The eraser test piece was made into vertical contact with the line on the test paper. Under a standard load of 0.5KG, the back-and-forth rubbing test was conducted at a speed of 36±2CM/MIN for four times. After that, the test paper was removed and the concentration was determined with a lead core concentration meter. This machine can also be used for the eraser wear rate test.

Brief Introduction:This instrument is specifically designed to measure the movement of the lead core within the sliding rod.
