Oil pump for gas and steam turbines
Main oil pumps supply complete steam turbine groups with more than 1000 megawatts of power with lubricating oil. Aartech is responsible for the procurement, manufacturing and assembly of all components as well as the worldwide spare parts service and thus accompanies the customer throughout the entire life cycle of the product.

challenges:

• More than 20 pump types with different dimensions (60 - 2'500 kg piece weight)
• Highest quality requirements to guarantee continuous operation in power plants
• Ensuring short delivery times for spare parts
• Full responsibility for all processes and project management
• International procurement of materials and components

Our solutions and services:

• In-house production of key parts as well as assembly and testing
• Delivery time and cost reduction through process optimization and alternative suppliers
• Use of Rapide Casting for pump housings for very small quantities
• Increasing the product lifetime in cooperation with the engineering
• Dual-source strategy for the most important components

Infrastructure housing for the railway industry
Housing for the railway infrastructure are exposed in most cases strong weather conditions and therefore have high demands on the quality of materials and workmanship. We take over the entire service starting with the engineering, prototype construction, production of the pilot series up to the relocation to "best value" countries. In this example, a cost reduction of over 40% was achieved for the customer. Thus, starting with the prototype up to series production, the optimal price-performance ratio is always guaranteed.

challenges:

• Cost pressure and high expectations regarding cost reductions
• High demands and quality of materials and workmanship
• Various product types, which only partially optimally fit the machine park.

Our solutions and services

• Procurement of raw materials and purchased parts in "Best Value" countries
• Transfer of all manufacturing knowledge to partner companies abroad
• Cost transparency through disclosure of books
• Regular benchmarking of the transferred products and suppliers
• Cost reduction of over 40% during the project period
• Ensuring perfect product quality

Shaft turning devices are needed for starting up and shutting down gas and steam turbines. They ensure that no damage to the turbine occurs during these operations and that the safety of the maintenance personnel is guaranteed at all times.

challenges:

• Precision gearbox with housing tolerances of 0.01 m
• Integration of complete gearmotors including parameter configuration
• Several functional and acceptance tests required

Our solutions and services:

• Cost-effective re-engineering for new transmission generations
• In-house manufacture of key components
• Procurement of raw materials and purchased parts in "Best Value" countries
• Mechanical and electronic assembly including quality control and testing
• Cost transparency through the entire value chain
• Cost reduction of over 30% in two years
• Worldwide spare parts availability within three working days
• Very short delivery times through strategic warehouse production

In our dust-free assembly room, we assemble and package complete calibration systems for cancer therapy.
Our service includes the production optimization of prototypes, the choice of the best procurement and production possibilities as well as the complete assembly and function control up to the packing and dispatch to the customer's central warehouse.


challenges

• Full traceability of all components
• Visible parts with highest demands on cleanliness and surface quality
• 100% logging of all reference mass

Our solutions and services

• Project management and full responsibility for the entire value chain
• In-house production of sheet metal and production parts
• Assembly including final inspection and packaging of the assemblies
• Create extensive quality documentation

Extractors for laser machines
Extractors are used in flatbed lasers for the rapid removal of process exhaust gases. We manufacture extensive sheet metal assemblies for the market leader in the field of laser systems and deliver them just-in-time to the customer's respective assembly plants in Switzerland and abroad. Our services start with the engineering of sheet metal assemblies, flat machining, folding, assembly of mechanical and pneumatic components up to the provision of export packaging.

challenges

• Delivery window of a maximum of 2 days
• Just-in-time delivery without buffer
• Great variety of different versions and types
• Modular delivery of different types

Our solutions and services

• Engineering support already during pattern production
• Production of all individual parts, warehouse or order related
• Quality guarantee and initial sample inspection
• Shortest delivery time and optimal warehouse management
• 100% delivery reliability
• Provision of assembly-optimized pendulum packaging

Mounting device for rotor caps of turbogenerators
For every service on the generators in thermal power plants, the foremost part of the generator, the rotor cap, must be removed before the inspection. Together with the customer, a modular hydraulic device was developed with which the rotor cap can be removed and shrunk back. Our service included the concept development, the evaluation of suppliers for the subsystems, the preparation of the detailed and detailed drawings incl. Operating instructions as well as the commissioning.

challenges

• Complex, multi-stage assembly process with heavy loads
• Worldwide use necessary with consideration of linguistic barriers
• Modular structure necessary due to different generator types
• Fast assembly and dismantling necessary including air and sea freight capable packaging

Our solutions and services

• Construction of a complete hydraulic-mechanical mounting device
• Ensure the CE conformity of all system components
• Create animated manuals for quick and safe startup
• Production, installation and commissioning of all system components
• Provision of reusable export packaging for worldwide use
