Injection molding of plastic parts
Combining metal and plastic into a single, reliable product
Spraying plastic onto metal parts
By injecting plastic onto metal parts, we combine the advantages of two materials into a uniform, functional and reliable product. The metal insert provides strength, rigidity, precision or electrical conductivity, while the injected plastic enables protection, insulation, sealing and the shaping of demanding functional surfaces.
Before injection molding, we precisely place the metal inserts into the tool, then, using a controlled process, we partially or completely coat them with the selected technical material. We pay special attention to the correct positioning of the inserts, the quality of the bond between metal and plastic, and the dimensional stability of the final product.
Automated and controlled process
By using robots and automated devices, we ensure the precise insertion of metal parts into the tool, the safe removal of products, and the efficient repetition of the production cycle. Automation reduces the risk of errors, improves traceability, and enables stable quality in large-scale production.
We adjust the process parameters to the type of metal, the selected plastic material, the product geometry, and its functional requirements. With controlled injection molding, we ensure a reliable material connection, high dimensional accuracy, and long product life.
By combining metals, technical materials and automated processes, we manufacture compact, precise and reliable components for the most demanding applications.
We can manufacture various components such as:
- metal axles and bushings with injection-molded plastic
- Mounting devices and fixing elements
- threaded inserts in plastic housings
- Electrical contacts and connectors
- functional automotive elements
- products that combine a metal core with complex plastic geometry
Advantages of injection molding on metal inserts:
- Combining multiple functions into one product
- less additional assembly operations
- reduction of the number of individual components
- high mechanical strength and stability
- protection of metal against external influences
- electrical and thermal insulation
- better repeatability and shorter production time
Different technical materials
The correct material selection is crucial for the quality, functionality, and lifespan of the final product. Based on its use, geometry, load, and customer requirements, we select the material with the appropriate mechanical, thermal, chemical, and electrical properties.
With advanced injection technologies, we process a wide range of standard and technical thermoplastics. Our experience also includes reinforced, modified, elastic, and colored materials intended for use in the automotive industry and other demanding technical environments.
We process various groups of materials, including materials based on PA, POM, PP, PE, ABS, PC, TPE and TPU, as well as their reinforced or otherwise modified variants. We also use materials with the addition of glass fibers, color concentrates and other functional additives according to the product requirements.
From preparing the material to a stable process
Each material requires proper preparation and precisely adjusted injection parameters. At the same time, we carefully control its storage, drying, dosing, processing temperature, and other key process conditions.
With modern production equipment, automated dosing and monitoring of process parameters, we guarantee stable quality, high repeatability and reliable production of small and large batches.
With the correct selection of materials, professional process knowledge and controlled production, we create technical products that reliably fulfill their function.
Materials for various requirements
Depending on the intended use, we choose materials that ensure:
- high mechanical strength and rigidity
- wear and impact resistance
- Stability at elevated temperatures
- resistance to chemicals and other environmental influences
- high dimensional accuracy and stability
- Good sliding and torsion properties
- electrical or thermal insulation
- elasticity, tightness and vibration damping
- high-quality appearance and color durability
Material adapted to the product
We help customers choose the material based on:
- predicted mechanical and temperature loads
- contact with oils, fuels, moisture or chemicals
- the required product lifetime
- Dimensional accuracy
- method of composition and further processing
- requirements regarding appearance, color and surface
- re-use and recycling options
Technical components for automotive door systems
We manufacture technically demanding plastic components and functional assemblies intended for installation in automotive doors and glass movement mechanisms. The products combine precisely designed plastic parts, gear transmissions, metal elements, and other functional components.
Each component is designed to operate reliably in the confined space of automotive doors, where it is subjected to repeated loads, vibrations, and temperature changes. At the same time, we pay special attention to the dimensional accuracy, mechanical strength, wear resistance, and stability of the materials.
From a single component to a functional assembly
Accuracy that ensures reliable operation
By selecting appropriate technical materials, controlled injection molding and automated production processes ensure high repeatability and stable quality. We adjust the process parameters to the product geometry, installation requirements, and expected loads during use.
During manufacturing and assembly, we monitor key dimensions and verify the proper operation of individual components. This ensures that the final assembly exactly fits the car doors and reliably performs its function throughout the vehicle’s lifetime.
Comprehensive customer support
We can be involved in the project already at the development stage and participate in optimizing the design, selecting materials, manufacturing tools, developing the production process, and establishing serial production.
From precise plastic components to reliable door mechanisms – we guarantee quality at every stage of production.
Our production capabilities include:
- holders and guides for car windows
- housing and functional parts of the door mechanisms
- gearboxes and elements for transmitting motion
- components with metal screws, plugs and other inserts
- multi-component plastic products
- assembled and tested functional assemblies
From idea to realization
We provide customers with comprehensive support in developing technically demanding products made of plastic materials. We can take on the project at an early stage and guide it from the initial concept and structural design to the manufacture of the tooling, testing, and stable mass production.
By integrating development, tooling, technology, production, and quality, we ensure that all phases of the project are coordinated with each other. Already during the preparation of the 3D model, we verify the product’s geometry, manufacturing options, material selection, and the requirements of the injection molding process. This way, we identify potential risks in a timely manner and find suitable technical solutions.
Comprehensive implementation of the project
Development with a focus on production
We adapt the product’s design to the manufacturing technology at the development stage. In doing so, we take into account its function, mechanical loads, dimensional accuracy, appearance, assembly method, and expected lifespan.
With prototypes and initial samples, we verify the design solutions, then, through measurements and optimization of process parameters, we ensure that the final product meets the agreed requirements.
One partner throughout the entire process
A holistic approach enables better control over the project, faster resolution of technical challenges, and shorter time from initial idea to serial product. Throughout the entire process, the customer has one reliable partner who connects all the necessary competencies.
From the first sketch and 3D model to the verified final product – we transform your idea into a reliable production solution.
Our cooperation can include:
- review of the idea and customer requirements
- Development and optimization of the structure
- preparation of 3D model and technical documentation
- selection of the appropriate technical material
- the production of prototypes and samples
- development and manufacturing of injection molds
