Testing Load Capacity of Long Compression Spring
Testing how much load a long compression spring can take is really important job. It show us the weight limit before the spring stop working good. At Lisheng we always make high-quality springs, and knowing this test is key for buyers and makers. This way make sure springs perform well in what they suppose to do.
Introduction
When you test long compression springs, doing it correct way matter a lot. First you need proper tools. Spring testing machine is good option, because it measure force apply to spring very well. Also know the original length of spring before compress it. Put spring in machine, then add weight slowly until compress to some point. Record that weight you add, this number tell how much load spring handle without damage. And its better do test few times to check if results stay same.
Benefits
There some important points when testing load capacity of compression springs. First think about material of spring. Different material handle different weight. Like steel springs usually hold more then plastic one. Another is how spring will use. If for heavy duty work, test under high load important. Environment also play role. Springs in wet or hot condition might need special material to prevent rust or change shape. Lastly always check spring after test for any wear signs. This help make sure you get good quality.
Quality
To find out strength of spiral torsion spring follow some best practice. First know what we test. Compression spring is kind that get shorter when push down. Load capacity mean how much weight it support without break. For proper test, check size and material first. Different material can take different weight, for example steel spring hold more compare to plastic.
Applicaton
Next make sure spring clean, no dirt or contamination. Dirt make flat coil torsion spring. Also check no damage like bend or crack, if have it wont work right. After prepare, set spring stable. Place on flat surface and secure so not move during test. Use load cell device for measure weight apply. Add weight gradual and careful, do slow to avoid shock spring. Record weight when spring start compress a lot, this point show load capacity. And always careful during test.
Conclusion
Beside this, maybe need weights to put pressure. Weights should easy add remove. Sturdy stand or platform help hold spiral tension spring steady. Notebook or computer good for record result. Track measurement important to see spring behave under load. And don't forget safety stuff like glove and goggle, protect yourself very important when deal with heavy weight and spring that can snap.
