Solution
- Software-controlled high-capacity test stand
- Custom fixtures to match test spring diameter and dimensions
Benefits
- Easy-to-use test procedure
- Same routine on maultiple spring designs
We purchased the MultiTest 10-i to test 80% of the springs which we have in our railcars. The system is very easy to use and the program is convenient to test. Also the support of A & D Korea was very positive.

Requirement
Seoul Metropolitan Railway Transit Corporation required a system for testing a variety of springs in their electric railcars. The springs range in size from 3mm to 100 mm in diameter.
Solution
To meet the specification, Mecmesin's distributor A&D Korea supplied a test system consisting of a MultiTest 10-i twin column test frame, driven by Emperor software, two intelligent loadcells and a selection of compression plates suitable for testing a wide variety of springs. This system is used to apply a compressive force to the springs with a pass/fail criteria of equal to or greater than 300 N. The customer chose Mecmesin MultiTest 10-i because the software is easy-to-use and the test system is price competitive.
Test equipment
- MultiTest 10-i
- ILC500 N / ILC10 kN
- 10 sets of compression plates and fixtures
