Seyunda was founded in Taiwan in 2004, selling spring machinery. Two decades later we both build the machines and run them in production. That combination is unusual, and it shapes how we answer technical questions.
WHY A MACHINERY SUPPLIER STARTED MAKING PARTS
In 2008 we began manufacturing springs, clips, and wire forms in-house rather than only selling the equipment that makes them. The reason was practical. When you sell a coiler, customers ask questions the datasheet cannot answer: what this machine does with that wire, at that tolerance, on a long run.
Running production ourselves is how those answers stopped being estimates. It also changed what we could tell a customer honestly. If a machine will struggle with a particular part, we know, because we have tried it.
WHAT CERTIFICATION ACTUALLY CHANGED
We certified to ISO 9001 in 2013 and to IATF 16949 in 2021. Neither was a plaque exercise.
- ISO 9001 in 2013: Formalized incoming inspection, calibration, nonconformance, and corrective action into a documented system rather than practice held in people's heads.
- IATF 16949 in 2021: Brought the automotive core tools into daily work. Control plans in prototype, pre-launch, and production versions. Measurement systems analysis on the gauges that matter. A defined reaction when a process drifts, rather than an operator's judgment call.
The automotive certification is the one that changed the shop floor most, because it forced the question of what happens when something goes wrong to be answered in advance and in writing.
THE FACILITY TODAY
We operate a 2,500 m² facility housing 25 spring and clip machines, serving customers in Asia, North America, South America, and Europe. Certifications cover ISO 9001, IATF 16949, and RoHS, with PPAP submission capability for automotive programs.
The product range runs from SMD and EMI spring contacts in beryllium copper, through compression, tension, torsion and spiral springs, to wire forms, clips, clamps, and clip nuts. On the machinery side we supply CNC coilers, versatile formers, wire and strip formers, benders, grinders, and industrial ovens.
WHY SINGAPORE, AND WHY NOW
The Singapore office opened in 2026 to shorten the distance between a customer's question and a useful answer. Production stays in Taiwan. What moves closer is quoting, technical discussion, and the back-and-forth that happens before a drawing is finalized.
For Southeast Asian customers that turns a time-zone gap into a same-day conversation, which matters more than it sounds when a design review is waiting on a feasibility answer.
WHAT RUNNING BOTH SIDES MEANS FOR YOU
Most spring makers buy their machines. Most machinery suppliers have never held a production tolerance for six months. Doing both has three practical consequences:
- Feasibility answers come from experience, not a spec sheet. When we say a wire diameter and tolerance combination is achievable, it is because we have run it.
- Machine recommendations account for the whole line. A faster coiler in front of an unchanged grinder moves the bottleneck rather than removing it. We have made that mistake ourselves.
- Parts and equipment are a single conversation. Customers who start by outsourcing parts and later bring production in-house can do both with one supplier, and we have no reason to steer that decision either way.
WHAT WE GOT WRONG ALONG THE WAY
Two corrections worth making publicly, because both appeared on this site and a supplier that quietly edits its claims is harder to trust than one that names them.
We have described the company as having decades of IATF 16949 manufacturing. That is not possible: IATF 16949 was first published in October 2016, replacing ISO/TS 16949, and we certified in 2021. What is true is that we have manufactured since 2008 and held automotive certification since 2021.
We have also described Dacromet as a chrome-free coating. It is not — Dacromet contains hexavalent chromium, and Geomet is its hexavalent-free successor. For vehicle parts that distinction matters, because the ELV Directive restricts Cr(VI).
Both are now corrected across the site. Neither was deliberate, and both are the kind of thing that gets repeated until somebody checks the source.
WHAT HAS NOT CHANGED
The company started by answering technical questions about machinery for people who had to make a part work. Twenty-two years on, that is still the job. The range is wider and the documentation heavier, but the useful conversation is the same one: what are you trying to make, and what has stopped you making it so far.
Send us your drawings, samples, or requirements and our engineering team — backed by 20+ years of spring and machinery manufacturing experience — will get back to you with a competitive quote and realistic turnaround.
