Operating across a total production floor space of 16,000 square meters, backed by an additional 11,000 square meters earmarked for ongoing construction and infrastructure expansion, our modern plant employs 130 highly specialized staff. This workforce is strategically structured into 80 expert shop-floor production operators and 50 dedicated personnel focused entirely on R&D, engineering, rigorous quality assurance, and global supply chain logistics.
Navigating the surging manufacturing demands within Portugal's core technological hubs.
Portugal’s modern metalworking sector (metalomecânica) has undergone a profound transformation. No longer confined to basic metal construction, Portugal has established itself as an innovative European hub for automotive, aerospace, industrial valve, marine machinery, and renewable energy sectors. Areas like Palmela (housing the critical Autoeuropa automotive cluster), the metallurgical clusters in Porto and Aveiro, and the rising aerospace ecosystems in Évora demand high-precision metal components that offer mechanical integrity under extreme stress.
"To satisfy stringent European safety and environmental standards, Portuguese engineering firms are increasingly replacing complex welded assemblies with near-net-shape, structurally homogeneous lost wax castings."
In marine engineering, the expansion of Portugal’s deep-water ports, such as Sines and Leixões, requires cast components capable of withstanding the harsh marine environment of the Atlantic Ocean. Standard metal sand castings fail to prevent micro-porosity and early crevice corrosion. By utilizing silica sol lost wax casting processes, designers can achieve smooth surface finishes (Ra 3.2μm or lower) and exceptional dimensional control, eliminating the need for expensive secondary operations.
Furthermore, as Portugal shifts heavily toward green hydrogen production and offshore wind farms, the demand for precision-engineered valves, pump components, heat exchangers, and structural connector brackets has skyrocketed. Global procurement officers are looking for reliable supply chain alternatives that combine design optimization, material science expertise, and large-scale manufacturing resilience.
Delivering high-tech metal forming and finish machining from prototype validation to high-volume production runs.
Processing high-alloy stainless steel, carbon steels, duplex steel, and specialized aluminum alloys. Our internal spectrum analyzers verify element profiles before pouring.
Equipped with state-of-the-art 4-axis CNC machining centers, automated CNC turning mills, and advanced friction presses for structural and complex geometries.
Holding both ISO 9001-2015 and SA8000 certifications, establishing a reliable baseline for quality management and ethical global production practices.
Modern manufacturing depends on predictable lead times and reliable quality. The traditional supply chain model is vulnerable to raw material volatility and geographical bottlenecks. At XinYe, we mitigate these risks by integrating advanced Industry 4.0 smart manufacturing technologies directly into our casting and machining production lines in Ningbo.
By leveraging computerized solidification simulation tools, our engineers evaluate thermal profiles and fluid dynamics before the first physical mold is generated. This minimizes internal shrinkage and internal defects, guaranteeing high yield rates and rapid prototyping.
Through automated wax pattern assembly, mechanical shell building, and real-time monitoring of autoclave de-waxing stages, we achieve consistent microstructural integrity across large production runs.
For Portuguese procurement teams, this digital manufacturing setup ensures that drawings sent from Lisbon or Porto are parsed and analyzed with absolute fidelity. The resulting tooling and casting steps are completely tracked to guarantee full process visibility.
High-capacity equipment configuration engineered to scale according to client production forecasts.
Our facility houses an array of high-tonnage forming machinery capable of handling diverse industrial footprints:
Post-cast precision requirements are executed via:
Our factory runs 16 hours a day across a standard 6-day workweek. To support fast scaling requirements, our operations can transition into full 24/7 continuous production mode within 30 days.
"Quality is Life" - Traceable validation from raw material ingots to final finished components.
Performs chemical alloy breakdown verification before pouring to confirm compliance with ASTM, EN, and DIN material grades.
Coordinate Measuring Machine provides automated 3D dimensional reports, confirming high-precision alignment.
High-magnification optical checking for micro-dimension verification on stamping and machined features.
Non-contact vision systems optimized for profile verification and complex structural features.
Ensures the surface finish of cast and machined areas satisfies requirements (e.g., Ra 1.6 - Ra 3.2).
Spring and material tension/compression verification systems validating mechanical load performance.
Our internal quality assurance protocols are built to meet European regulatory expectations. With our ISO 9001:2015 and SA8000 certifications, we guarantee both dimensional quality and ethical labor compliance across the entire manufacturing cycle.

We process stainless steel (e.g., CF8, CF8M, CF3M matching 1.4408, 1.4404, 1.4308 EN codes), alloy steels, carbon steel, duplex steels, and various aluminum formulations. Every pour undergoes spectrographic testing to verify chemistry limits conform to ISO, DIN, EN, and ASTM parameters.
Tooling fabrication and initial sample casting typically take 7 to 10 days, depending on geometry complexity. Once sample inspection sheets and dimensional reports are approved, mass production orders are completed and ready to ship within 20 to 30 days.
We run solidification simulation analyses on design geometry prior to cutting tooling. For critical parts, we perform non-destructive tests (NDT), such as ultrasonic, magnetic particle inspection, or radiography, verifying internal density meets specifications.
Most sea shipments go directly from Ningbo Port to Lisbon or Leixões, with transit times averaging 28 to 35 days. For rush requirements, air cargo to Humberto Delgado Airport (Lisbon) takes 5 to 7 days. We handle export documentation, packing lists, and Certificates of Conformity (CoC) to simplify customs processing.
We require all international orders to have an ongoing minimum order quantity. While we support prototype and development runs, we optimize pricing based on volume. Please contact our engineering department with your target design profiles and projected annual usage for a tailored quote.
