Zilken supplies machined parts and custom-made components manufactured to drawings for a wide range of industrial applications. The product range extends from turned, milled, and sheet metal parts to protective and functional plastic components, as well as high-alloy special components made from heat-resistant steels and corrosion-resistant stainless steel alloys—all manufactured according to customer drawings, standards, or samples.
Whether turned, milled, laser-cut, bent, cast, or injection-molded: Through our manufacturing network, we produce custom parts using all standard processes—from CNC-turned and milled parts to sheet metal blanks and bent parts, as well as die-casting, investment casting, sintered parts, and metal injection molding (MIM). This means we are not tied to a single manufacturer, but rather select the process that best suits the geometry, quantity, and material.
We source formed parts made of quenched and tempered steel, free-cutting steel, heat-resistant 25CrMo4, A2/A4 stainless steel, and highly corrosion-resistant 1.4529, as well as aluminum, non-ferrous metals, and engineering plastics such as polyamide, POM, or PVC. Rubber and elastomer molded parts, as well as special materials such as 1.4462 duplex, 1.4541, or high-alloy nickel alloys, are also available through our procurement network—a total of more than 28 materials in our current product range.
We source materials in accordance with applicable material, dimensional, and testing standards—ranging from material standards such as EN 10269, EN 10025, and EN 10088, to pressure vessel regulations such as DIN 2510 and the AD 2000 guidelines, all the way to general tolerances per ISO 2768 and fits per ISO 286 for parts manufactured to drawings. Determining the current version of a standard is not a research task for us, but rather part of our daily routine.
About a quarter of our molded parts are supplied with a Type 3.1 inspection certificate in accordance with EN 10204—including batch-specific documentation of material properties. For example: For a power plant project, we procure expansion bolts made of heat-resistant 25CrMo4 in accordance with EN 10269, covered by AD-2000 data sheets W7 and W2, with each batch documented in a traceable manner. Where required, we also provide 3.2 certificates with external countersignature or initial sample test reports (EMPB/PPAP) for series production approval.
Zilken’s forming technology covers a wide range of applications: cut-to-size parts, sheet metal formed parts, and custom-designed components for mechanical and plant engineering; protective caps and functional elements for sensitive assemblies; expansion bolts and threaded bolts for flange and pressure vessel connections; as well as sleeves, spacers, profiles, and wire mesh. From cryogenic applications at -196 °C to heat-resistant applications at +570 °C—available on request as individual pieces with material certification or in bulk quantities.

Through our supplier network, we can also source high-temperature-resistant nickel alloys such as 2.4668 (Inconel® 718) or 2.4819 (Hastelloy® C-276) upon request, high-performance plastics such as PEEK or PVDF, as well as custom-made parts produced using specialized processes like wire EDM, hot forging, or additive manufacturing (SLM/FDM) for applications beyond our standard product range. The same applies to parts meeting aerospace standards, medical technology requirements, or offshore applications. If your specific requirement is not listed on this page, please contact us.
Zilken streamlines procurement for Siemens Energy through a European manufacturer cluster—enabling faster delivery times, tax-neutral processes, and greater planning reliability for critical components in plant and mechanical engineering.
Customers who purchase parts based on a bill of materials can also receive them as pre-assembled sets. We put together assembly-specific kits and component sets—pre-sorted, labeled, and ready for installation. This reduces the time and effort required for part separation during production and keeps inventory levels low.

Fittings, gaskets, fasteners, and other C-parts can all be ordered in a single purchase order, through a single point of contact, and delivered in a single shipment. As your system partner, we handle supplier selection, certificate management, and incoming goods inspection—so your procurement team can focus on strategic tasks.
Yes, upon request. These industries have specific requirements regarding certification, traceability, and documentation, which we meet through specialized suppliers in our network. Please coordinate the specific standards and acceptance criteria directly with us.
Through our network of suppliers, we offer the following manufacturing processes: CNC turning, CNC milling (3- and 5-axis), laser cutting, waterjet cutting, punching, punch-bending, and injection molding. For specialized processes such as wire EDM, hot forging, or additive manufacturing (SLM/FDM), procurement is available upon request.
Yes. We assemble screw sets and fastener sets according to your bill of materials—sorted, labeled, and ready for installation. Learn more on our assembly page.
No, these are not included in our standard product range. However, through our procurement network, we can source high-alloy nickel alloys such as 2.4668 (Inconel® 718) or 2.4819 (Hastelloy® C-276) upon request, complete with the appropriate material certification and acceptance test report.
Yes. We source custom-made parts from sheet metal (steel, stainless steel, aluminum) and bar stock based on customer drawings—including surface treatment and material certification. Please submit the drawing and bill of materials via the inquiry form.
A significant portion of our molded parts are supplied as standard with a 3.1 certificate in accordance with EN 10204. This is our standard practice for pressure vessel and power plant projects in accordance with AD 2000. A 3.2 certificate is available upon request.
Sealing technology for maximum plant availability: O-rings, flat gaskets, and mechanical seals prevent leaks—standardized or manufactured to drawing.
Pipeline technology for safe media transport: pipes, fittings, and flanges according to DIN or drawings—ready-to-install systems for liquid and gaseous substances.
Fastening technology for every application: screws, nuts, rivets, and bolts—DIN parts and custom-made products from small quantities to large series.
