Holding doors and flaps closed with a spring hinge
Spring hinges are used to make doors open or close automatically. The ideal addition to a flap hinge with spring is a snap lock or slam latch.
The spring hinge consists of two hinge halves with interior torsion spring. When the door is opened, the spiral spring in the hinge is compressed, generating an opposing force. Once the door is released, the folding hinge with spring returns to its initial position, closing the door.
Ganter carries spring hinges made of robust die cast zinc or glass fiber-reinforced plastic as well as a variety of sizes and torque values.
Despite their compact design, hinges with spring-loaded return offer a long service life. Tests have shown that the spring tension remains fully intact even after 100,000 closing cycles.
