Our service portfolio
Thanks to our more than 40 years of experience, we are able to offer our customers an extensive portfolio of different products and services. In addition to our core expertise in the mechanical machining of die-cast aluminum components and components from other materials, we also offer comprehensive post-development advisory services along the entire value creation chain and beyond.
Our customer-orientated approach is reflected in our everyday work, the relentless pursuit of perfection. Our aim is to exceed our customers’ quality requirements and expand on them with our in-house quality demands.
Berlin Millhouse GmbH is committed to precision, innovation, and sustainability. We stand for highest quality and think in micrometer tolerances.
High-pressure water jet cleaning
Our high-pressure water jet cleaning system enables us to remove production residues from components at pressure of up to 500 bar. This guarantees clean and precise refinement and finishing of our components.
With our ECM deburring technologies, we can remove burrs and flash from even the most convoluted components by the interaction of a cathode individually matched to the workpiece, an electrolyte, and high electric current at low voltage. The process is appropriately adapted for the component with regard to the time and the electric current.
Components leaving the production line pass through a fully-automated cleaning station in which remaining production residues such as coolants and lubricants are removed by washing. Cleansing by the individually definable chemicals contained in the cleaning bath is supported by cleaning with rotating, high-pressure water jets. In the cleaning station, the components are washed at temperatures of around 80°C. In an integrated vacuum-drying process, the cleaned components are dried and appropriately cooled for subsequent applications.
Compressed air leakage testing
Compressed air leakage testing is performed in a separate climate-controlled room to verify the components’ required resistance to leakage. In this process, automated pressure testing is enabled by tools individually fabricated to fit the component. On completion of testing and approval, each component is labeled with a unique serial number.
3D coordinate measuring technology
As a part of the serial production testing regime, 3D coordinate measuring plays a substantial role in our value creation chain and is performed in a separate, climate-controlled room. This room is where the fulfillment of our stringent quality standards is verified before a component can be prepared for delivery. High-precision systems from Zeiss and Mitutoyo enable us to check the final dimensions with extremely tight tolerances in the micron range. The detailed documentation of the automated measuring procedure is then processed and prepared for delivery to the customer.
The trained eyes of our colleagues check the otherwise inaccessible parts of our products with an endoscope to verify compliance with the customer’s specifications. After approval, each individually checked component is labeled with a seal that confirms its compliance with our most stringent quality standards.
Technical cleanroom facility
In our technical cleanroom facility, microscopic examination enables us to identify even the finest particles. This room is especially equipped for the purpose of conducting particle measurements, which are then appropriately evaluated and documented. Thanks to state-of-the-art equipment we are able to identify particles with sizes of less than 25 microns.
In process engineering, we integrate the individual specifications for our products in the production line to ensure efficient and sustainable production. In his way, we achieve the enormous flexibility required for the fulfillment of tightly scheduled production deadlines. The tooling and subsequent setting takes place in a special area, in which special tool measuring and setting units (Mapal Uniset P) are employed to ensure fulfillment of the customer’s specifications.
Thanks to cutting-edge technologies, the issuing of tools is also partially automated. Almost every component is provided with a dedicated clamping fixture for each of the machines used in the production process. This is manufactured and serviced in collaboration with our customers and partners.
Our continuous servicing and centralized predictive maintenance guarantee the extremely high technical availability of our machine park. Systematic root cause analysis helps in the prevention future defects and enables us to achieve efficient and sustainable production.
Our aim is to exceed the customer’s quality requirements.
Customer Service & Project Management
We offer our customers everything from one single source: “One single point of contact” – includes everything from the examination of the customer’s request for a quotation, the preparation of an offer, the selection and management of suppliers, to the sourcing of raw materials, production, final assembly, refining, finishing, and delivery of the components. Thanks to our many years of experience, we are able to offer our customers an extensive portfolio of advisory services.
At Berlin Millhouse GmbH, quality assurance is firmly anchored in every step of the value creation chain. Our employees, our suppliers, and our customers can therefore all contribute to assuring and guaranteeing our most stringent quality standards.
We have a passion for quality. We are motivated by our firm commitment to convincing our customers with the outstanding quality of our products and processes.
Building on our more than 40 years of experience and certifications, we have realized and implement our quality management procedures in accordance with, amongst others, the following criteria:
- Supplier development
- Constant quality checks along the entire value creation chain
