Dingli Spring will exhibit at PTC ASIA 2026 in Shanghai from November 3 to 6. Meet us at Booth E3-L3-2 to discuss your spring requirements.
Compare rectangular and round wire compression springs by force at equal deflection, deflection at equal force, and the permitted working range. Real product photographs and an assumed linear example explain the differences.
Sourcing custom miniature compression springs requires more than a sample or basic print. Discover how early design alignment and pre-delivery optical length inspection help engineering and incoming quality teams establish reliable spring acceptance criteria.
Follow Dingli Spring's 65Mn round-wire coiling footage and see how drawing requirements, forming, end geometry, post-processing and inspection connect in a custom spring order.
A torsion spring can fit the shaft and still provide the wrong return action. Learn how to align winding hand, viewing direction, angular positions and mounting clearance before approving a replacement.
A practical guide to defining preload, working travel, acceptance criteria and report evidence for die spring fatigue testing and supplier RFQs.
Mid-year tooling maintenance is when most replacement die spring orders are placed, and it is also when the most expensive selection mistakes happen. The shop pulls a worn spring out of a die, sees it
Compare ISO 10243 die spring colors, separate core and extended grades, and check housing fit, working loads, preload and total deflection before ordering.
