Immediate high-precision manufacturing solutions configured for medical, aerospace, and general advanced engineering fields across France.
As the capital of France and the center of the Île-de-France region, Paris serves as a critical technological hub for European aerospace, medical technology, defense, and electric vehicle (EV) innovation.
From the research centers at Paris-Saclay to the advanced mobility facilities in the Seine Valley, Parisian companies demand subcontracted components that meet strict European Union quality standards. The transition toward high-mix, low-volume (HMLV) specialized products requires a highly responsive manufacturing partner. Our facilities bridge the gap for Parisian designers who need rapid prototyping and production-grade parts without regional bottlenecks.
With an emphasis on compliance with the French aviation, automotive, and defense industries, we ensure all components adhere to strict dimensional tolerances, high surface integrity, and certified material traceabilities.
How our smart production network in Dongguan overcomes logistics barriers to offer unmatched speed, quality, and cost savings for Parisian companies.
Operating out of Dongguan—the world's capital of precision manufacturing—we maintain direct relationships with localized raw-material foundries and specialty surface finishers. This mitigates raw material delays, ensuring consistent delivery to Paris even in challenging economic landscapes.
Our workshop integrates advanced multi-axis machining technology. By combining milling and turning operations, we eliminate multiple set-ups, drastically reducing human error while maintaining positioning tolerances below the ±0.005mm threshold.
Our experienced engineering team evaluates the Design for Manufacturability (DFM) of every STEP file. We identify draft issues, corner radius limitations, and material waste opportunities before production begins, lowering cost-per-part metrics for Parisian startups and OEMs.
Dongguan SX Technology Co.,Ltd has very rich experience in precision casting, CNC machining and assembly.
Our products are used in machinery, automobiles, marine, ships, equipment, valves and pumps, electronic appliances, packaging, watches, construction, chemical industry and other industries. The most commonly used materials for investment casting are stainless steel and carbon steel. And the most commonly used materials for CNC machining include titanium alloy, stainless steel, carbon steel, aluminum alloy, copper alloy, cemented carbide, etc.
We have advanced manufacturing equipment and technology and are able to respond quickly to your needs.
Take a look inside our manufacturing floor where precision components undergo machining, milling, and turning operations.
Quality is the cornerstone of the manufacturing industry. We firmly believe that only by controlling quality well can we survive, develop, and get better and better.
We have professional testing equipment and professional QC personnel, and we adhere to strict tolerances and quality standards for the products we produce. Due to our insistence on strict quality requirements, we have been praised by many customers. Therefore, we have been working in this industry unremittingly since 2014 and continue to improve the company's team and improve the company's production capacity.
OEM solutions customized to complex geometries, serving the automotive, robotics, and consumer electronic sectors of Île-de-France.
Providing deep customization options across modern industrial materials including specialized alloys and custom polymer compounds.
Navigating total cost of ownership (TCO) and quality assurance when sourcing precision metal parts.
For modern procurement officers in Paris, calculating the real cost of machined components extends beyond the unit price. It must cover logistical overheads, import duties under EU rules, and the risk of dimensional non-conformity. By choosing a manufacturer that pairs investment casting with precision post-machining, engineering firms save up to 35% on material waste and finish processes.
Furthermore, we support diverse transport arrangements, including express airfreight directly to Charles de Gaulle (CDG) airport or cost-effective rail transport for volume runs, managing the customs clearance pipeline seamlessly.
Our operations leverage advanced QA mechanisms, including X-ray flaw detection for cast preforms, optical emission spectrometers for strict metallurgical certification, and Coordinate Measuring Machines (CMM) to map high-precision geometry. Every shipment includes comprehensive dimensional and material reports, giving French industrial clients maximum confidence.
Providing clear, straightforward technical answers for engineers and purchasing agents ordering CNC components.
Our standard production lead time for prototypes is 3–7 business days, while volume manufacturing runs generally take 15–20 business days. Standard air freight from our Dongguan facility to Paris (CDG Airport) takes approximately 3–5 business days, and sea shipping takes 30–35 days.
Yes. Every batch of machined components is delivered with official raw-material test certificates (conforming to EN 10204 3.1) showing physical and chemical properties. We also supply certificates of conformity and RoHS/REACH compliance reports upon request.
We maintain strict ISO 9001:2015 control guidelines. Our climate-controlled inspection room features coordinate measuring machines (CMM), height gauges, profile projectors, and thread gauges. Standard tolerances are ISO 2768-m (medium) or f (fine), with critical dimensions held up to ±0.005mm.
For 3D data, we accept STEP (.step, .stp), IGES (.iges, .igs), and SolidWorks files (.sldprt). For 2D engineering drawings (critical for marking tolerances, surface finishes, and thread specifications), we prefer PDF, DWG, or DXF formats.
We provide a comprehensive range of finishes, including bead blasting, clear and color anodizing (Type II and Type III hardcoat), passivation, electroplating (zinc, nickel, chrome), powder coating, laser engraving, and electropolishing for stainless steels.
