Compression springs
At Šumer d.o.o., we manufacture compression springs with over 30 years of experience in spring production. Our products are made on modern CNC machines equipped with electronic sensors for real-time quality monitoring, ensuring consistent precision across every batch. Wire dimensions range from 0.05 mm to 25 mm, in round, flat, elliptic, rectangular and custom cross-sections.
These springs store mechanical energy under compressive load and return to their original length when released — ideal for automotive, electronics, medical and industrial applications. We produce both small prototype batches and large series to meet your exact requirements. Learn more about spring standards at ISO.org.
