At Šumer d.o.o., we manufacture compression springs with over 40 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.
Our processes are certified to ISO 9001 and IATF 16949.
We manufacture springs on modern CNC machines that monitor product quality in real time using electronic sensors.
We offer pre-protected wire (Zn, AlZn, Cu, …), phosphating, electroplating, KTL paint, powder coating and heavy-duty zinc flake coatings (Dacromet, Doerken and similar).
This spring type is part of a wider range that includes tension springs, torsion springs, leaf springs and bent elements. See the full springs range.
Send us your drawing or sample and the required quantities through our inquiry form, and we will prepare an offer. It helps if you tell us the wire diameter and material, outer diameter, free length, number of coils, type of ends and the load the spring must carry.
