Custom technical products and prototypes

We specialise in the development and production of high-quality cast parts, plastic parts, aluminium profiles, prototypes and components. Why? Because we are true experts with extensive experience in these product areas. And because we can supply you with the perfect solution for your needs as a result. Our products are made according to our specifications by manufacturers as experienced as we are – with uncompromising quality and in any lot size (if needed also in small quantities). We will support you from the development of an idea and the production of a prototype to series production. All parts will be supplied with the desired surface treatment: galvanic chrome, nickel, gold and/or wet-coated or powder-coated.

Our products

Cast parts

Aluminium high pressure die-casting, zinc high pressure die-casting, magnesium high pressure die-casting, aluminium sand casting, aluminium gravity die-casting with surface finish.

Plastic parts

Injection-moulded parts made from high-tech plastics for mechanical engineering, the lighting industry, the sanitary sector (for all material classes) as well as technical thermoplastics

Aluminium profiles

High-quality, customer-specific aluminium profiles, including with complex parts geometries, off-the-peg or sawed and mechanically machined


Quickly produced prototypes as close-to-series-production aluminium, bronze, brass, zinc and magnesium investment casting parts


Stamped parts and stamped bending parts for all industrial sectors, aluminium, brass and stainless steel solid material parts, stainless steel connecting elements, screws, nuts, DIN and standard parts as well as pre-finished assembly products

Hinges, closures, accessories

Rolled or milled hinges, e.g. made from steel, stainless steel, brass and aluminium as well as all kinds of closures and accessories

Metal Injection Molding (MIM)

Metal injection molding combines the simple shaping process of injection molding with the material properties of metal and ceramics. Perfect for components with complex geometries. Highly efficient with optimal reproducibility.

In addition to the development and production of high-quality, needs-based cast parts, plastic parts, aluminium profiles and prototypes, we also ensure that you can use your products as quickly as possible.

Cast parts

Using different casting processes, Kirch develops and produces requirement-specific castingsmade from all standard raw materials. Upon request, we will then provide your high-quality castingswith a galvanic or Teflon coating, paint them and assemble them.

We are producing castingsusing
the following processes:
  • Aluminium pressure die-casting
  • Zinc pressure die-casting
  • Magnesium pressure die-casting
  • Aluminium sand casting
  • Aluminium gravity die-casting
Surface finishing &
service for cast parts
  • Electroplating
  • Teflon coating
  • Wet coating
  • Powder coating
  • Assembly

Plastic parts

Flexibility is our greatest strength in the plastic parts segment – especially in small and medium lot sizes. True to the motto: "There is no such thing as 'we can't do that'." That is why we are using a wide range of raw materials and finished products to manufacture plastic parts, which also allows us to complete short-term projects. The injection-moulded parts made from high-tech plastics and technical thermoplastics are used, among others, in mechanical engineering, the lighting industry and the sanitary sector.

We are also offering decorative plastic metallisation through vacuum coating. That allows us to give copper, aluminium, tin, gold or silver coatings different metallic effects, such as a stainless steel, aluminium, old brass or gold effects – and even colourful top coats are possible.

We use the following raw materials to produce plastic parts:
  • Thermoplastische Elastomere (TPE)
  • Acrylonitrile butadiene styrene (ABS)
  • Acrylonitrile styrene acrylate (ASA)
  • Cellulose acetate (CA)
  • Liquid crystal polymer (LCP)
  • Polyacrylamide (PAA)
  • Polyamide 6 - 6.6 -12 (PA)
  • Polybutylene terephthalate (PBT)
  • Polyethylene (PE) Polycarbonate (PC)
  • Polymethylmethacrylate (PMMA)
  • Polyphenylene oxide (PPO)
  • Polyoxymethylene (POM)
  • Polyphenylene ether (PPE)
  • Polyphenylene sulphide (PPS)
  • Polypropylene (PP)
  • Polystyrene (PS)
  • Polyurethane (PUR)
  • Styrene-acrylonitrile resin (SAN)
  • Thermoplastic elastomers (TPE)



Depending on the material, we also produce plastic parts with a glass-fibre, mineral-fibre or carbon-fibre content.

Aluminium profiles

Kirch will develop and produce high-quality aluminium profiles for you according to your individual specifications. We can produce even complex designs with top precision and quality. In any quantity.

Our services in the area of aluminium profiles:
  • Off-the-peg or sawed
  • Pressing
  • Cutting
  • Bending
  • Coating
  • Assembly


Prototypes for castingsare essential when the function of the product has to be checked prior to series production or during the so-called parallel development. In order to shorten the time-to-market of products, it's all about maximum speed and flexibility.

Kirch facilitates the quick development and production of prototypes for castingswith materials that are, for the most part, the same as those used for series production. In particular, small batch producers of machines, machine components, vehicles or other products will benefit enormously from this. This allows the weekly, monthly or annual production of individual castingson commission. That allows you to prevent high storage costs and losses due to altered versions.

Our services in the area of
prototypes for cast parts:
  • 3D printing
  • Master pattern: Shrink-corrected made from plastic, wood, metal
  • Rapid prototyping (SLA, FDM, SLS or similar): From CAD files (stl, Stepp, iges)
  • Milled parts: Aluminium, bronze, brass, zinc and magnesium


You need high-quality castingsor stamped bending parts, aluminium, brass and stainless steel solid material parts according to your specifications? You are looking for stainless steel connecting elements or screws and nuts as DIN versions or as standard parts? Kirch will develop and produce needs-based components for a wide range of uses and industries. With top quality and in any lot size you want.

Our services in the area of components:
  • Assembly
  • Blister packaging
  • Electrical testing
  • Commissioning
  • Labelling
  • Warehousing

Hinges, closures, accessories

We will develop rolled or milled high-quality hinges, closures and accessories for a wide range of uses. We can produce standard or customer-specific versions of all hinges, closures and accessories for you. It's up to you.

Here is what our hinges,
closures and accessories have to offer:
  • Short lead times from an idea to series production
  • Short delivery times
  • Low tool costs
  • High quality
  • Materials: Steel, stainless steel, brass, aluminium and other types of metal
  • Rolled or milled versions

Metal Injection Molding (MIM)

It is much more difficult to process metal and ceramics than plastics using traditional production processes such as machining or casting. Metal injection molding, however, makes it possible to combine the simple shaping process of injection molding with the material properties of metal and ceramics. This pays off, especially in the case of components with complex geometries. The products are also very reproducible, even in high quantities – at low unit costs.

    How you benefit from metal injection molding:
    • Tailor-made products with a variety of finishes
    • Ideal for complex components thanks to narrow tolerances
    • Outstanding reproducibility for all batch sizes
    • Ready-to-install components with low unit costs
    • Highly efficient and resource saving through material recovery of almost 100%
    • Environmentally friendly due to recyclable components
    • Lighter weight compared to components produced with other processes

    Ex stock Rottweil

    We can warehouse and deliver your products directly from our company headquarters in Rottweil upon request. This also allows you quick access to your products while reducing your warehousing and employee capacities and lowering logistics costs.

    Our internal warehouse currently has 500 pallet bays. We also have access to an additional 1,000 external pallet bays. So we can store and supply even large quantities without any problem. Incoming and outgoing goods are monitored by cameras that, thanks to automated, computerized image documentation, provide maximum security as well as traceability of the products.

    A service that literally pays off for you!
