Punched parts

Efficient metal processing for complex requirements

Modern stamping technology is a key metalworking process in which flat materials are precisely formed into defined shapes. With high process speeds and minimal material loss, it enables the economical production of complex components - in both small and large quantities. Our range of services covers the entire spectrum from prototype production to series production - precisely, flexibly and tailored to your requirements.

Customized stamping technology - from prototype to large-scale production

As Wienker GmbH, we are your contact for high-precision stamped parts - whether as bulk material or from strip material. Our modern production facilities and decades of experience make us the ideal partner for your requirements. Our punching systems are designed for high flexibility - from simple contours to complex geometries with tight tolerances. Typical areas of application for our stamped parts:

Automotive industry: carrier plates, brackets, contact springs
Electrical engineering: connector housings, circuit board contacts
Medical technology: filigree functional components with tight tolerances
Household appliances: housing parts, sight and cover plates

The materials can also be pre-processed. Whether pre-galvanized, tin-plated, milled or selectively finished - you tell us your specification, we offer you the solution.

We guarantee short delivery times.

Variety of materials - the right metal for every requirement

We process a wide range of metallic materials - precisely tailored to your application. Both untreated and pre-processed materials are possible, e.g. pre-galvanized, tin-plated, milled or selectively refined.
Our common material options:

Whether electrically conductive, high-strength or corrosion-resistant - we process exactly what your component requires.

Stamping technology process chain - from the idea to the finished component

Our punching processes don't just start at the press, but also with technical advice. Together with you, we develop optimized solutions that meet your requirements economically and functionally.

We support your project right from the development phase with CAD designfeasibility analyses and FEM simulations in order to identify potential material and cost savings at an early stage.

Our in-house toolmaking department produces individual stamping and progressive tools - precise, low-maintenance and durable. On request, we can also produce rapid construction tools for functional samples and pre-series.

Our punching technology is designed for medium and large quantities. Automated feed systems and sensor monitoring ensure consistent quality and short cycle times - ideal for industrial series applications.

Cleaning, inspection, logistics - added value through in-house solutions

As a special highlight, we have our own in-house washing system. This means we can also clean bulk goods immediately, without external detours - efficient, cost-saving and time-saving.

Another plus: our fully automatic sorting system enables 100% inspection of your components with suitable geometry - for maximum safety and documented quality down to the 0 ppm target quota.

Finishing & external post-processing - your advantage with strong partners

For further finishing steps, we rely on long-standing, certified partners. This means we can also easily meet individual requirements:

Surface treatments: e.g. galvanizing, black oxidation, passivation
Electroplated coatings: Gold plating, silver plating, nickel plating
Heat treatments: Stress relief annealing, hardening
Deburring & grinding: manual or automated
Trowalizing & vibratory finishing: for burr-free, clean edges

You receive all services from a single source - managed and organized by us.

Packaging & warehousing - flexible according to your needs

We think beyond the component. That's why we offer you a customized consignment warehouse on request - directly at our premises or at your site. We pack your parts in an environmentally friendly way, also in your customer's own packaging - labeled, punched or blistered.

Frequently asked questions (FAQ)

Our production is designed for a variety of metals. Among other things, we stamp:

Aluminum stampings for lightweight housings and electronic components
Stamped parts made of stainless steel for corrosion-resistant applications
Bronze and brass stampings for electrical contacts
Stamped parts made of chrome-nickel steel for high load capacity
Spring steel stampings for spring tensioning applications
Copper stampings for high conductivity
Stamped sheet steel parts for robust technical components

Also aluminum sheet metal up to a thickness of 3 mm - including pre-finishing if required.

Stamped-bent parts are produced in a combined manufacturing process in which the material is not only punched, but also bent directly. As an experienced manufacturer of stamped and bent parts we make complex geometries possible in one continuous production step - particularly economical for medium to large series.

Yes, we also process pre-galvanized, tin-coated or selectively refined sheet materials. Through our certified partners, we also offer surface finishes such as galvanizing, gold plating, silver plating, chrome plating and hardening, tempering and powder coatings to.

Depending on the tool and material, a minimal burr is created during punching. We reliably remove this by mechanical, thermal or chemical deburring. Deburring is an important step for safety and function, especially for high-precision stamped parts made of metal such as stainless steel, spring steel or non-ferrous metals such as copper or bronze.

Yes - we manufacture specific metal stampings for applications in gas technologye.g. brackets, housing elements or technical interfaces made of stainless steel. stainless steel, aluminum or brass. High tightness, dimensional stability and material quality are a matter of course.

Our processes are optimized in such a way that we can achieve tolerances in the tolerances in the hundredths or even thousandths of a millimeter range depending on the material, geometry and batch size.

Yes. Our own toolmaking develops and manufactures individual sheet metal punching tools - precisely tailored to your components, materials and production quantities. This allows us to react flexibly and realize short delivery times.

Naturally. We offer stamped parts from small quantitiesincluding tool development and prototype construction. Thanks to modular tool systems we can also realize one-off productions economically.

Yes - we offer customized packaging solutionsfrom environmentally friendly packaging to customized blisteringlabeling or the creation of a consignment consignment stock. Our logistics processes therefore fit perfectly into your supply chain.
