Custom Extension & Tension Springs

DG Vifort specializes in manufacturing high-quality custom extension springs, also known as tension springs. Designed to absorb and store energy, their performance is defined by their durable hooks and precise initial tension—and that is where our expertise shines.

Solving the Most Common Extension Spring Problems

An extension spring is only as strong as its ends. We hear from clients who have experienced failures with other suppliers, and we have engineered solutions for these critical pain points:

• The Problem of Hook Failure: The spring hook is the weakest point and often breaks under load.
  Our Solution: We design and manufacture a wide variety of robust hook types (English loops, German hooks, side hooks) and ensure proper stress relief to prevent breakage at this critical point.

• The Problem of Overstretching: The spring is pulled beyond its elastic limit and becomes permanently deformed.
  Our Solution: We help you select the right high-tensile material and design parameters to ensure the spring operates well within its limits, providing a long, reliable service life.

• The Problem of Incorrect Initial Tension: The spring is too loose or too tight before any external force is applied.
  Our Solution: Our precision coiling process gives us finite control over the initial tension, ensuring your spring engages exactly when and how you need it to.
