On-Demand Manufacturing for Industrial Parts

We source industrial components from Asia β€” finding the right manufacturer, controlling quality on-site, and delivering to your door under European standards. You send a request. We do the rest.

On-site in Asia
Our team visits factories and monitors production directly in China.
Supplier Audits & QC
We qualify suppliers and inspect every batch before it ships.
Competitive Prices
Asian manufacturing costs with Swiss-level quality oversight.

Not suppliers. Audited partners.

We don't maintain a large directory of factories. We maintain a short list of verified manufacturers we know, have audited in person, and trust to deliver to our standards β€” every time.

Quality over quantity. Every manufacturer in our network holds ISO 9001 certification and has passed our own on-site qualification process before receiving a single order.

01
On-site qualification

Before any manufacturer enters our network, we visit their facility in person. We assess their QMS, equipment, workforce and quality culture β€” not just their certificates.

02
Matched to your project

Each project is matched to the right partner β€” not the cheapest or the fastest, but the one with the right process, capacity and experience for your specific component and volume.

03
Long-term relationships

We work with our partners over time, not project by project. This means they understand our standards, our documentation requirements and our expectations β€” without needing to be retrained on every order.

ISO 9001 All our manufacturing partners are ISO 9001 certified
On-site audited Every partner visited and qualified in person by our team
Flexible network Adapted to your industry, process and production volume


From Prototype to last spare part

We are not a one-time transaction. From your first drawing to the last spare part ordered years later, we stay your single point of contact β€” managing quality, traceability and continuity at every stage.

01
Design Validation

From drawing to certified sample. We review manufacturability, select the right process and deliver fast.

02
Process Validation

Full production part approval. Balloned drawing, dimensional report, process flow chart, packaging sheet.

03
Mass Production

Stable repeated runs. On-site audits, inline inspections, every batch delivered to your specs.

04
After-Sales

Re-order spare parts years later. Same quality, same traceability, same Swiss contact.

Confidentiality is not optional

Every project we handle is treated as strictly confidential β€” by contract, by process, by default.

NDA with every supplier

Before any technical document is shared with a manufacturer, we sign a bilateral non-disclosure agreement. Your drawings, specifications and project details are legally protected at every step of the supply chain.

Drawings stripped of your identity

Your company name, logo, part numbers and any identifying information are removed from all technical drawings before they reach a supplier. The manufacturer sees a part β€” not who ordered it or why.

Supplier isolation β€” no cross-exposure

Each supplier only ever sees their own scope. When a project involves multiple manufacturers, none of them know who else is involved, what the full assembly looks like, or who the end customer is.

Everything stays inside ZENTIOR

Project details, costs, supplier names, lead times and commercial terms are strictly internal. Nothing is shared outside our team β€” not with other clients, not with partners, not with anyone. What you share with us stays with us, period.

Engineers, not traders

Zentior was built by two engineers who lived the problem from both sides β€” one in Switzerland, one on the factory floor in Asia.

Steeven Gaschin

Managing Director

Switzerland

Based in Switzerland, I lead Zentior's client interface, governance and strategic sourcing strategy. With over ten years of experience in international industrial environments, I built my career at Forvia, holding roles in production quality, project quality and industrialization. I spent seven years at Forvia across Portugal, France and Germany, contributing to automotive programs for Renault, KIA, SEAT, Ε koda and Volkswagen. I later joined the Liebherr Group as a supplier process auditor and strategic purchasing team leader, strengthening my expertise in supplier qualification, risk mitigation and global sourcing strategy.

Anthony Dumazert

Head of Operations

China

Based in Asia, I lead Zentior's regional operations and supplier network. With an engineering background and seven years in the automotive industry, I worked across France, the United States and China. At Forvia, I led the industrialization of complex products for Ford under strict automotive quality and performance standards. I later spent four years in China as Asia Quality Manager for La Foir'Fouille, overseeing supplier quality, leading a team of eight QC/QA specialists, and securing supply-chain performance in close collaboration with local partners. With over ten years of on-the-ground experience in China, I understand the local industrial ecosystem and communicate effectively with Chinese suppliers.

Extended Supply Chain Services

Beyond sourcing and delivery, we provide the technical infrastructure and on-site presence needed to scale your production safely.

Quality Doc Package

We compile a comprehensive quality documentation package tailored to your needs, including dimensional reports, material certifications, and compliance data to ensure full traceability for your internal approval process.

Lab Testing β€” SGS

Chemical composition, mechanical properties, and dimensional verification performed by SGS. You get raw third-party laboratory data with full traceability, not just a self-issued certificate.

Design Optimisation

Our engineers propose modifications to reduce manufacturing costs without affecting function. We look at tolerance relaxation, material alternatives, and geometry simplification with concrete cost impact estimates.

Factory Audit

We perform on-site audits of our network or your own existing suppliers. We assess QMS, machine capacity, and labor standards to give you a neutral, high-resolution view of the factory floor.

On-site Inspection

Flexible on-site presence: first-article inspection, in-process monitoring, or final AQL sampling before shipping. We verify visual, dimensional, and functional criteria at any stage of production.

Warehouse & Stock

Strategic storage options close to your facility or in Asia. We maintain safety stock and manage inventory levels per your requirements, providing detailed stock reporting and zero-lead-time availability.
