Manufacturing Prototypes and Small Series
We can design and produce prototypes and small batches for pre-series production. With a wide range of materials and a multitude of processes – and all this within a short production cycle.
Key Advantages
Short production time
High surface quality
Versatile materials
Our own production and cooperation with specialized partners
Large components up to 4 m²
In-house surface treatment and refinement/coating
Fused Deposition Modeling (FDM)
Fused Deposition Modeling (FDM) or Fused Filament Fabrication (FFF) is especially
suitable for the production of economical prototypes. The materials used include PC, PLA, ABS, PVC, TPU and Ultem. They are fed to the extruder in filament form and are melted down. The displacement on the linear axes creates a three-dimensional component.

Selective Laser Sintern (SLS)
The rapid prototyping process is suitable for cost-efficient manufacturing of components with high surface quality. The construction volume is filled with powdery material and melted at specific points by a laser. After a cooling process the model is ready.
In this rapid prototyping process, the powdery material is heated in the construction volume to almost its melting point. Wherever a component is to be produced, dark ink is applied in the form of the finest drops. Due to the heating cycle, heat is absorbed. The material fuses with the ink. The process is repeated layer by layer – until the component is finished.
Here the component is milled in a fully automatic process from the solid material. A high degree of dimensional accuracy is achieved by the high machine precision. Materials from the later series process can be used to manufacture large components with high surface quality.

Vacuum Casting
A silicone mould is created by placing a master model in silicone. The master model is then removed by separation. After the silicone is reassembled, it can be filled with resin.It solidifies to the shape of the finished component. The silicone mould can be reused several times.
The design, construction and handling of large injection moulds are our speciality. No matter how complex the moulds are, we design the right tool for the job, realized and optimized by our worldwide tool partners under the best conditions. So that it meets German quality standards. After each production cycle, the mould is inspected, maintained and properly stored.
Key Advantages
Production from low to high quantities
Small and large components up to 4 m²
Selection of several technical procedures
Design, stability and surface quality
Locking forces up to 32,000 kN in injection moulding
Environmentally friendly use of recycled plastic and grist
Injection moulds and handling of up to 60 tons of weight
Development and construction according to German quality standards
Processing of all common thermoplastics and customised material development
Know-how and quality engineering in process and tool development
Mould Design
We develop moulds for complex product geometries. Tool cavity development goes hand in hand with component development. The perfect injection process can be designed with the aid of a mould filling simulation. The injection points and hot runners as well as the slide gates and slide gate separators are optimally designed. Component-optimised mould cooling is also another option. The design of the component surfaces ranges from a polished mirror finish to an etched structure. The tool configuration and steel selection ensuring a long service life complete the design.
Mould Manufacturing and Procurement
Fried stands for innovative engineering and unique component functionality. In order to maintain our highest quality standards, we procure tools worldwide according to our own specifications. As part of a long-term cooperation with selected international suppliers. We ensure that the moulds made by our partners are produced and optimised according to the German quality standards under the best operating conditions.
Mould Maintenance and Modifications
Not only do we develop our own tools up to a handling capacity of 60 tons, we also service them on site and properly store them in safe houses. We also perform tool modifications independently. This shortens response times and makes us particularly fast and flexible.
The Fried compact injection moulding process makes it possible to produce components of various shapes and sizes of the highest surface quality. For example, smooth and textured surfaces. It is particularly suitable for thin-walled components. Plastic granules are dispensed into the so-called snail by plasticizing and dosing, where they move towards the end of the snail. The friction heat generated by shearing melts the material.
The liquid melt is injected into the cavity via a nozzle. After the cooling phase the mould is ready. Thanks to hybrid technology, Fried offers the possibility of encapsulating external materials with plastic. A wide variety of materials such as ABS, PA, PC, PS, PE, PP, POM, ASA can be used. But also recyclable materials, fiberglass-reinforced granulates, FDA-listed materials and many more.
Key Advantages
Processing of all common materials
Ideally suited for light and thin-walled components
Highest surface quality in colour and appearance – from mirror finish to textured
Consistently high quality through automated process control, from low to high quantities
Possibility of environmentally friendly use of recycled plastic and g
High degree of design freedom
Inmoulding of metal components using hybrid technology
Structural foam injection moulding is recommended for the production of rigid components. Differences in wall thickness can be easily produced without any sink marks. The process ensures that additional pressure is created in the cavity by adding a blowing agent to the plastic granulate. The expansion process inside the component creates a foam structure and a compact, closed outer skin on the surface. Even complex components can be filled without any problems.
Key Advantages
Processing of all common materials
Components with high strength and geometrical accuracy thanks to tension-free processing
Large component dimensions possible
Suitable for monocoque constructions with metal-like strength
Weight reduction due to foam structure
Sound and vibration damping effect
High functional integration and design flexibility in one component
Consistent quality even in small quantities thanks to automated process control
Possible use of environmentally friendly use of recycled plastic and grist
Injection compression moulding is a special form of compact injection moulding. It enables the production of very large components with low locking forces. During the injection process, the mould cavity is left slightly open. This allows the melt to be pressed into a tool that is almost pressureless. It is only closed during the solidification process via the compression stroke. After the injection process, the component is brought into its final shape by the compression stroke.
Key Advantages
Cost-efficient production of large, flat components
Even wall thickness due to parallel control
Allows for very thin wall thickness
Sophisticated internal geometries are easily achievable, with high integration of functions
No warping or tension, flat components
Also available in combination with multi-component injection moulding
The machining of plastic components enables the fulfilment of special functions and the creation of follow-up processing options.
To this end, the following methods are used, among others:
Milling
The mechanical finishing of plastic parts using 6-axis robots and milling machines enables a greater variety of products.
Plastic Welding
To weld composite structures, the technology of hot plate welding is used. The high strength and rigidity of a component are achieved by sealed bodies.
