Pull test results of the NK joint ring.

Pull test results of the NK joint ring.

Report on the tensile test of the NK joint ring, which does not require a mold for the connecting O-ring.

～NK Joint Ring Test Items and Methods～ ■ NK Joint Ring Tensile Test Items Tensile Test: Conforming to JIS K 6251:2004 ■ NK Joint Ring Tensile Test Method Specimen Shape: 250mm × φ5.6mm Grip Distance: 50mm Test Speed: 100mm/min Number of Specimens: 2 Room Temperature: 23℃ ～NK Joint Ring Tensile Test Results～ To clarify the results, the test was conducted using an NK joint ring made of two different colored rubbers. ■ Results ■ The rupture occurred not at the boundary between the two colors (the adhesive surface of the two types of rubber), but in the central part where the force was applied. The cross-section spanning the two colors also demonstrated that the joining precision of the NK joint ring is high and can withstand strong tensile loads. Test Sample: NK Joint Ring (different colors) Test Item: Tensile Test (joint section) Maximum Tensile Load (unit: N): 156

Reverse engineering

Reverse engineering

One-stop service from measurement to production! Introducing technology that reproduces parts without drawings with high performance.

Do you have concerns like 'I need a part but only have the physical item without a drawing' or 'The part is damaged, but I can't find the same part and consulting everywhere is a hassle...'? We can solve that problem with the technology of 'Reverse Engineering.' We measure the part to create a drawing and then create a 3D model using 3D CAD. Based on that design information and drawing, we manufacture the part. If you have any questions, please feel free to consult with us at Equal. 【Workflow】 ■ Confirmation of the physical item (on-site confirmation available) ■ Three-dimensional measurement ■ Drawing ■ Approval ■ Production processing ■ Inspection and delivery *For more details, please refer to the PDF document or feel free to contact us.
