H&R develops and produces springs for numerous applications in almost all areas of technology.
H&R stands for competence and flexibility in the field of industrial springs. From a simple ballpoint pen spring to springs for heavy duty purposes, we can put your wishes into practice. H&R develops and produces springs for numerous applications in almost all areas of technology. Our technical support by our engineers in the project planning phase, during dimensioning, material selection, spring calculation, analysis of the spring function and design support, together with implementation in production, ensures a tailor-made product. The relevant properties such as statics, dynamics, low relaxation, fatigue strength, temperature resistance, special (UV-resistant) corrosion protection, etc. are met depending on the specific requirements and quality specifications. In-house tests such as fatigue strength tests, crack tests and salt spray tests flank the quality in development and production.
The best way to benefit from our experience is to discuss the technical requirements of the springs with us at the project stage already. Whatever your needs for special springs may be, we will be happy to advise you on dimensioning, material selection and all other technical questions. Our name stands for the quality of our products, today an in the future.
