Production areas
The range of materials we use is second to none! From 5 mm steel strip to soft plastic seals, we process materials and combine them to create functionally integrated assemblies!
We do not limit ourselves to one class of material, but combine metals and plastics to create innovative composite products. Our customers mainly come from the automotive, medical and household technology industries. What they have in common is a high demand for efficiency and quality. We also produce components for locking and building technology. We provide them with everything from a single source: the metal inserts are prepared in our own stamping shop and then injection molded with a plastic component.
The result is metal-plastic hybrid products with a high load-bearing capacity and an integration of functions that often make additional components superfluous.
Our precision plastic products are primarily used in the electronics, locking technology and powertrain sectors. Our international customers value our high precision and our fully or partially automated production processes. Optimum throughput times, efficient processes, flexible component assembly and modern machinery ensure first-class products and top quality.
We are certified according to IATF 16949, ISO 9001 and 50001.
As a competent technology partner and thanks to our many years of experience in the automotive industry, we produce high-precision and technically sophisticated injection molded parts in the white goods sector. We are familiar with the high temperatures, chemical and mechanical stresses, so we can also advise on materials, design and cost optimization.
As a member of an international group of companies, we offer ideal conditions for efficiently serving the household appliance market. With standardized processes, we guarantee high quality, flexibility and short delivery times worldwide.
We mostly use technical plastic granules for medical molded parts in order to meet the high requirements in terms of quality, hygiene, resilience and appearance. For example, the claddings and panels must be able to withstand radiation exposure from MRI and X-ray machines as well as contact with disinfectants and medication. We also use many technological options to integrate functional elements made of other plastic components and metal.
Only a few suppliers have mastered hot gas welding, in which the joining zone is plasticized using radiant heat and a stream of hot shielding gas. A free design of the weld seam and its course with three-dimensional weld seams can only be realized in hot gas welding. Furthermore, hot gas welding does not produce any particles or thermal damage to the material. The high-strength connection without mechanical stress on the workpieces also means that no undesirable deformations occur. It is even possible to weld internal ribs in order to reduce the load of tensile and shear forces on the weld seam and significantly increase the strength of pressure vessels. The hot gas welding process is generally suitable for all thermoplastics. Even plastics that are considered difficult to weld, such as PBT, POM, PPO and PPS, are securely joined together.
Of course, we also use other welding processes such as laser, ultrasonic and vibration welding for a variety of different products.
Article optimization, cost savings, weight reduction, function integration …
We repeatedly encounter many topics in discussions with customers across all industries. We can therefore draw on a wealth of experience and use this to optimize components together with you. With our high level of vertical integration, we have a correspondingly large scope for material combinations, automation, tool designs and much more.
Since our company was founded in 1924, we have continuously developed our expertise to the point where we are now specialists in metal-plastic connections. We never stand still and seize new opportunities. That is why we have been part of the OKE Group since the end of 2017, whose international orientation we use within the group of companies.
With OKE, we benefit from many synergies such as the interplay of technologies, the Group’s special machine construction and logistical advantages. Central administrative units are also located in the holding company.
Metal-plastic hybrids are popular across all industries. Today, around 60 percent of all metal stampings are directly or indirectly joined with plastic. And there are good reasons for this! Intelligent metal-plastic hybrids are created by taking into account value-adding ideas or following a precise analysis of the potential for added value, and our customers benefit from this:
The best thing about us is our many great colleagues. We spend a lot of time at work and attach great importance to good interaction, a motivating working atmosphere and valuing everyone. Schröder is part of the OKE group of companies and is a medium-sized family business. For all our employees, this means flat structures and quick decisions, coupled with the opportunities of a global company.
In 2024, we will celebrate our 100th anniversary. Strictly speaking, however, there was already a forge before 1924, which was founded by Wilhelm Schröder. Stove and window knobs, bed hooks and all kinds of other everyday items were created under his management. A world war, economic crises, the history of industrialization and globalization lie behind us.
An eventful time in which Wilhelm Schröder has continued to develop – and often reinvented itself. We carry this idea of development and transformation to our customers and are open to new technologies, processes, markets and challenges!
Gustav Schröder is considered to be the founder of the current location. The simple forge becomes a small production company. With automatic bed hook machines, an eccentric press, six machines for the production of tacks (rivets and nails for shoes) and a few small auxiliary machines, the path to industrial production begins.
Bankhaus Otto Geck declares bankruptcy – Gustav Schröder has to prove his entrepreneurial spirit in his very first business year. And he actually succeeds in making a new start in business.
The workforce grows, additional machines are purchased, production and the product range are expanded.
German troops invade Poland. With the start of the war, the production of shoe pins and heel plates for the soldiers’ boot production is rapidly growing.
Machinery and the entire warehouse are destroyed by shelling, and the buildings are destroyed down to their foundations. Gustav Schröder estimated the damage at around 300,000 marks.
Despite all the depression, reconstruction begins. However, enormous efforts are required before the factory building is back in its shell at the end of 1945.
Production is resumed. However, as the company has already been rebuilt by 1947, there is no entitlement to equalization payments.
The currency reform puts the brakes on Gustav Schröder once again, as the Deutschmark devalues savings enormously. Purchasing power also falls due to the change in wages as prices rise.
The stable new currency and a great deal of entrepreneurial spirit bring an economic upturn. Millions of our bed fittings are exported to Nigeria, and after the difficult years, we celebrate our 25th anniversary.
The production of shoe fittings is discontinued and the stamping shop is expanded. In addition to production facilities such as automatic punching machines and presses, we also advertise with “well-trained personnel”.
Our need for space increases and a two-storey extension is built. Gustav Schröder is nicknamed ‘Schoppen Gustav’, as from now on he expands Schoppen by Schoppen.
Plastic becomes THE material for industrial mass production. Gustav Schröder once again demonstrates his entrepreneurial spirit and enters the plastics production business in 1955, the automotive industry places its first orders with us.
The first automatic punching presses are purchased – and in the following years, the eccentric presses are phased out. This enables significantly more efficient production.
Generation change: Klaus Wilhelm Schröder joins the company on April 1 and manages the company until March 1999. First together with Manfred Ahlhaus and from 1985 with his nephew Dirk Ahlhaus. Dirk Ahlhaus remains with the company until 2007.
Even after the era of ‘Schoppen Gustav’, construction work continues to accompany us. A hall for the stamping shop was inaugurated in 1981, a stamping shop and logistics building in 1997, and in 2014 we expanded our production areas by 4,000 square meters.
The development of plastics applications, technologies and interdisciplinary cooperation are important to us. That is why we are a founding member of the Lüdenscheid Plastics Institute, a network with over 400 members today.
Toolmaking is outsourced and the subsidiary schnitt+form is founded. In the same year, we officially comply with DIN ISO 9001, followed by VDA 6.1 and QS 9000.
With the first automated systems, we start with assembly technology. A fully automated rotary table system for mechanical dishwashing components is one of the first applications.
Flooding is a recurring event in our company history. This year, we escaped with a scare. In order to be in a safer position for the future, we are participating in the development of a flood protection concept.
Kai Okulla takes over Dirk Ahlhaus’ shares, followed nine years later by those of Knut Schröder.
In the midst of the global financial and economic crisis, we set up a new plastics production facility with additional injection molding machines of 200 and 550 tons for the partial production of hybrid parts made of metal and plastic.
The year is characterized by a major renovation: we gain efficiency through an additional 4,000 m² and a restructuring of all work areas. New offices and social areas are also created.
The international OKE Group becomes the sole owner of Wilhelm Schröder GmbH.
Health management is introduced. Gradually, fitness rooms, prevention and sports facilities are created for all employees.
We are investing extensively in renewable energies with the construction of a large photovoltaic system.
