Overmolded metal parts / multi-component injection molding
Multi-component injection molding combines the positive properties of Plastic and elastomer or metal in a component. This opens up a wide range of application examples.
Multi-component molded parts often appear together where the properties of a single component are not sufficient. The hard component to absorb mechanical loads, the soft component as a seal, protection or damping. In many cases, engineers design two separate components for this. This requires additional investment and increases the effort in production and quality assurance. However, this additional effort can be significantly reduced through clever design in the development phase.
Insert & outsert technology
Metal and plastic parts are firmly connected by insert technology. Threaded sockets, screws, plug contacts or various inserts are placed in an injection molding tool and connected to the thermoplastic substrate.
The outsert technique is similar to the insert technique, in which plastic elements are sprayed onto a metal carrier. The difference is that the metal insert has a larger volume than the plastic. In addition, we also supply machined Metal components in an elastomer compositeThe basis for these components is a milled metal component (e.g. stainless steel, aluminum-zinc or copper alloys), which is integrally bonded to the elastomer is glued. Common materials include silicone, EPDM, NBR, etc.
Combination of different color and hardness variations
Different color and hardness variations of the soft component allow for numerous variants that can be specifically adapted to the requirements of customer-specific applications. By selecting suitable elastomer materials, specific damping characteristics can be achieved, for example. The milled metal base allows for classic shaft-hub connections or screw threads for connecting to peripheral elements. Other applications include sealing elements in mechanical and plant engineering, shock absorbers in the automotive sector or transport rollers in industry.

About metal moldings
Metal molded parts are a central component in manufacturing technology. These parts are made from metal using specific shaping and can be designed from various materials such as steel, aluminum, copper or brass. This diversity allows for an enormous range of shapes and sizes, tailored specifically to the needs of different industries.
There are many different technologies for producing metal parts, such as casting, rolling and deep drawing. Each of these technologies has its own advantages and disadvantages and is suitable for different applications.
die-cast metal parts
In the production of Die-cast parts The preparation of the molds plays a central role as it determines the final shape of the part. In the next step, the liquid metal is injected into the mold under high pressure, where it hardens. After cooling, the part is removed and post-processing is carried out to achieve the final specifications. This process enables the production of complex parts with high precision and excellent surface qualities.
A punching tool cuts precise parts out of a metal roll or sheet when producing stamped parts. This technique enables the rapid and high-volume production of components, establishing it as a cost-effective method for mass production.
deep-drawn metal parts
The Deep drawing process is a type of forming technology in which flat sheets of metal are clamped in a press and formed into a deep-drawn shape using a die. This enables the production of complex, three-dimensional parts with high precision and is particularly suitable for the production of hollow, symmetrical components.
turned and milled metal parts
Turned parts are manufactured using a machining process in which the material is removed from a rotating workpiece. This is usually done on a lathe, and allows for the creation of very precise and complex parts.
In the manufacture of milled parts The material is processed by machining, whereby the workpiece is rotated instead of the tool. Modern CNC milling machines enable the production of high-precision and complex components with maximum efficiency and repeatability.
contact springs and battery contacts
Specialized forming or punching processes bring metal wires into the desired shape and thus enable the precise production of contact springs. The subsequent heat treatment is used to give the springs the elasticity and strength they need. After this process is complete, specialists further process or refine the springs if necessary in order to specifically improve their performance and service life.
Multi-component molded parts
Finally, at the Plastic and rubber overmolding of metal parts the metal components are covered with a layer of plastic or rubber. This is usually done through injection molding, in which the plastic or rubber is injected into a mold in which the metal part is already located. This technique offers several advantages, including improved corrosion protection, increased electrical insulation and a more pleasant feel of the final product. In addition, this method can expand the functionality of the part and improve its aesthetic appearance.
Our metal molded parts are used in many different industries used, for example in the automotive industry, in mechanical engineering, in electrical engineering and electronics, in aerospace and in medical technology.
