Technical excellence
Metrology, audits and engineering experience under one roof.
Weld measurement, first-article inspection and documented reports — quality you can verify on paper.
SzMuri Co. LtdSourcing · Quality · Shenzhen
Development, sourcing, inspection and manufacturing in China — with German quality standards and direct proximity to production.
SzMuri was founded to create connections — between idea and execution, between production and quality, between Europe and Asia. Our founder Christian Gassner has supported companies in optimising their processes on the ground in China for over 20 years.
We stand for intercultural bridging competence, technical know-how and a genuine hands-on mentality. What drives us: technical excellence, partnership at eye level, forward thinking and cultural openness.
„Quality, to me, is more than a test criterion — it is the benchmark for how I act.
Metrology, audits and engineering experience under one roof.
Weld measurement, first-article inspection and documented reports — quality you can verify on paper.
Collaboration at eye level — no black-box sourcing.
You see who we work with, what it costs and where your project stands — transparent across the whole supply chain.
Spot problems early. Deliver solutions before costs arise.
DFM advice and risk assessment before the first tool — we prevent mistakes instead of fixing them expensively later.
Bridges between German norms and Chinese manufacturing.
German, English, Mandarin — we translate not just language, but expectations and standards.
From the first sourcing conversation through tooling and injection molding to the fully assembled board — everything from one source, measurable and traceable. Scroll through the stations.
We connect European quality standards with Asian manufacturing power. Through local presence in Shenzhen, process control and technical expertise we create transparency, reliability and measurable results.

Quality is measurable. Our quality assurance combines experience with modern measuring technology — for precise control of every step. Documented from first sample to final approval.

Continuous improvement is part of our DNA. Through audits, process checks and coaching we help partners raise quality and efficiency for the long term.

Fast execution, high precision and full transparency: we develop and manufacture PCBs and assembled boards (PCBA) — from pre-series to scale.

In our in-house tool shop we build molds, fixtures and precision parts with the highest dimensional accuracy — from concept to handover.

With modern injection-molding systems we realise plastic components at the highest repeatability — from sample to series production.

Every step is technically reviewed, documented and aligned directly with partners on site.
We clarify requirements, target costs, volumes, quality expectations and project scope.
Sketches, samples or CAD data are assessed for feasibility, risks and manufacturing logic.
Suitable suppliers, tools or prototypes are built and coordinated on site.
Samples, dimensions, surfaces, functions and processes are checked and improved.
Series release, shipment supervision and final documentation close the project cleanly.
From single component to assembly: SzMuri owns the operational proximity to manufacturing and keeps quality transparent.

PCBA prototypes and plastic parts are developed, tested and prepared as a coordinated set for further production.

Visible parts with high surface quality including packaging control and documented approval before export.

Electrical accessories, metal parts and consumer goods including export, inspection and supplier communication.
One-stop solution for development, sourcing, inspection & manufacturing in China.
Three completed projects with key figures, images and exactly what we took on. One click opens the details.

From data set to released series: the mould was milled in-house, tried out and moved into running production.

Board, enclosure and cable set from one source — assembled, function-tested and packed ready to ship.

Supplier change for a family of turned parts — including audit, first articles and approval before every export.
Dedicated contacts guide your project technically, linguistically and operationally between Europe and Asia.


Short answers on services, production, quality and communication.
We develop and build industrial tools, manufacture products in-house, or identify reliable production partners. We oversee the entire manufacturing process — from the initial concept to the final quality inspection prior to export.
Our partner factories are located in China, Malaysia, India, Vietnam, Germany, and the Philippines. All projects are coordinated directly from our base in Shenzhen.
Basically anything that requires a tool — from plastic or metal parts to complex assemblies. Whether it's a banana-shaped pen or precision machinery, we make serial production possible.
Absolutely. Many projects start with a sketch or CAD file. We turn it into the right tool and manage the entire production process.
Before shipment, our inspectors check your goods on-site according to international standards. You receive a detailed inspection report with photos and measurements — before the container leaves Asia.
Yes. We research, vet, and negotiate with the right producers to ensure your product is made efficiently, safely, and at a fair price.
Kaizen is an additional service offered exclusively to our existing clients. It's a practical coaching approach designed to improve internal processes within your own production environment.
Usually within just a few days. Once we receive your product data or sample, tool development can begin immediately.
In English, German, or Chinese — depending on your preference. You'll have a dedicated contact person guiding you through every step.
Because we're based in Asia, operate with German precision, and treat every project as if it were our own. Hands-on, transparent, and reliable.
