Quality assurance of metal springs - springs, stamped and bent parts, 3D - bent wire parts
Our quality assurance for metal springs the methods, techniques and standards:
Quality Assurance plays a vital role in our company's metal spring manufacturing process to ensure that the required standards and requirements are met are equivalent to. Effective quality assurance measures allow potential defects to be identified and remedied at an early stage in order to ensure optimal product quality. We use special methods and techniques for quality assurance for metal springs and use the EN ISO 9001 and VDA 6.3 standards to optimally meet customer requirements.
Methods and techniques for quality assurance of metal springs include:
Dimensional Measurements:
Using measuring instruments such as calipers, micrometers or optical measuring systems, the dimensions of the metal springs are checked to ensure that they meet the specified tolerances.
Spring characteristic tests:
Here, the spring characteristics, i.e. the ratio of force to deflection, are measured. This enables the spring stiffness and elasticity to be checked precisely.
Load cycle tests:
These tests are used to verify the strength of the metal springs under repeated stress. The springs are continuously loaded and unloaded to determine their lifespan and resilience.
Surface inspection:
Through visual inspection or the use of technologies such as roughness gauges or metallography, the surface quality of metal springs is evaluated to ensure they are free from defects or damage.
Material analysis:
Using spectral analysis methods such as X-ray fluorescence analysis or metallography, the composition of the spring material is checked to ensure it meets specified requirements.
Various standards apply to quality assurance for metal springs, including EN ISO 9001 and VDA 6.3.
EN ISO 9001 is an internationally recognized standard for quality management systems. It specifies the requirements for an effective quality management system that ensures that customer requirements are met and continuously improved.
The VDA 6.3, on the other hand, is a standard specifically for the automotive industry. It defines the requirements for a quality management system in the automotive supply chain and refers to the special requirements of this industry.
Various machines and equipment are used in the quality assurance of metal springs, including:
Measuring machines:
Coordinate Measuring Machines (CMM) enable precise dimensional measurements and geometry verification of metal springs.
Tensile and compression testing machines:
These machines are used to test the strength and resilience of metal springs and to determine their mechanical properties.
Hardness Testers:
Hardness testers are used to measure the hardness of the spring material to ensure it meets specified requirements.
Metal Spring Quality Assurance is vital to ensure product quality, meet customer requirements, and ensure spring reliability. By using effective methods, techniques and standards, high quality and reliability of the metal springs can be guaranteed.
The importance of precise measurements in the manufacture of metal springs
The quality of metal springs largely depends on precise measurements of their properties and dimensions. Various measuring devices are used to ensure that the springs meet the specified requirements. In this article, we will take a closer look at the most important measuring devices for metal springs and identify their main differences.
Digital Profile Projector IM-6000:
Our IM-6000 series digital profile projectors are state-of-the-art measuring instruments that enable precise measurements of metal springs. With its digital image processing technology, it can quickly and accurately measure various parameters such as the diameter, number of coils and pitch of the springs. The IM-6000 offers a user-friendly interface and automatic calculations, saving time and effort.
Analog profile projectors:
Our analogue profile projectors use optical magnification and projection techniques to create detailed images of the feathers. With the help of scales and measuring marks, different dimensions of the springs can be read off manually. Although they don't offer the same automation as digital profile projectors, analog profile projectors are reliable and easy to use.
Torsion meter:
Our torsion meters are specially designed for measuring the torque of torsion springs. They enable the torsional stiffness and the angle of rotation of the springs to be precisely determined. Torsion meters are often used in combination with other measuring devices to enable a comprehensive characterization of the spring properties.
Spring Balances:
Our spring scales are specially designed for measuring spring force. They enable the spring force to be precisely determined in Newtons or kilograms. Spring scales are used to analyze spring stiffness and spring force-displacement characteristics to ensure they meet the required force ranges.
Load change machines:
Our load alternators are special machines designed to test the strength and life of metal springs under repeated stress. They allow springs to be continuously loaded and unloaded to evaluate their fatigue properties. Load change machines provide an efficient and accurate evaluation of springs for durability and resistance.
The main differences between the various measuring devices lie in their functionality, accuracy, automation and complexity. Digital profile projectors provide precise and automated measurements, while analog profile projectors require manual interpretation. Torsion meters specialize in measuring torsion springs, while spring balances focus on measuring forces. Load change machines enable a comprehensive evaluation of the springs under real load conditions.
The selection of the right measuring device depends on the specific requirements of the metal springs and the desired accuracy of the measurements. By using the appropriate measuring equipment, precise quality assurance can be guaranteed to ensure the performance and reliability of the metal springs.

The torsion spring:
Cylindrical torsion springs or also known as torsion springs, helical torsion springs are widely used and versatile machine elements components in the world of mechanics and spring technology.
The structure of a cylindrical torsion spring consists of a wire that is wound in a helical shape around a central axis in even turns.
torsion springs are used to absorb and release a rotating movement, a torque or a force and to guide the movement of the legs.
torsion springs are characterized by the ability to absorb and release deflections, forces or torques around a rotation axis and to guide the rotational movement.
torsion springs usually have a cylindrical spring body on which two legs are arranged.
The legs can be arranged tangentially, radially or axially, whereby each leg can have a different arrangement. Different spring end shapes can be attached to the end of the two legs, e.g. straight leg, hook shape, eyelet shape, round or square.
The terms "torsion spring", "torsion spring" and "torsion spring" refer to the same component.

The double torsion spring:
Double torsion springs, double torsion springs and double torsion springs are widely used and versatile machine elements in the world of mechanics and spring technology.
The structure of a double torsion spring consists of a wire that is wound in a helical shape in even turns to form two separate spring bodies. The two spring bodies are connected by a wire, which is usually designed as a U-shaped web.
The legs or spring ends of the double torsion springs are usually attached to the outside of the respective spring body. The force or torque is introduced either via the U-shaped web or via the legs. The double torsion spring is usually guided via a mandrel, axle or bolt.

The wire bent part:
In practical use, standardized wire bent parts such as spring rings, snap rings, retaining rings, clips, pins, etc. are found. A paper clip or a staple clip also belongs to the wire bent parts, wire form springs and bent parts.
However, in practical use, non-standardized, individual, application-specific designed wire bent parts are mostly used. Wire form springs and bent parts are used.
The focus is on the function of the component: e.g. securing, protecting, holding, positioning, clamping or springing.
Wire form springs, wire form springs and bent parts made of spring steel wire are important components in various industries and applications. Bent wire parts are special machine elements that usually have springy properties.
