MECHANICAL ENGINEERING

INVESTIGATING AND ENGINEERING

We can produce the dimensioning, modelling, production drawings and other documentation needed in maintenance planning and research and development of new products. We also take responsibility for project management in mechanical planning, from initial planning all the way to construction supervision.

We follow the industry-specific requirements and we are familiar with planning and manufacturing techniques. We pay particular attention to understanding the customer’s needs, quality control and scheduling in each of our customer projects.

The design software we use includes AutoCAD, Autodesk Inventor, Creo, NX and SolidWorks.

 

VEHICLE ENGINEERING

EXPERTISE THAT STANDS OUT

The cabs in working machines, such as tractors and cranes, have developed immensely over the course of time. Ergonomics, placement of controls, visibility, lighting, sound insulation, heating/air-conditioning, anti-vibration systems, components intended for heavy-duty use in challenging conditions and maintainability are examples of matters our designers work on.

We excel in the manufacturing of formed parts made from plastic or steel and the production of complex surface models. Expertise in plastic materials in designing the dashboard panels, as well as designing external panels and modelling A surfaces complement cab planning, for example.

In addition to static stress calculations, we perform simulations that aim to ensure and test the safety of the ROPS and FOPS structures for cabs.

TOOL ENGINEERING

PRACTICAL COMFORT

We engineer the tools for manufacturing, production and service.

Tools that are designed according to customer needs and current requirements are practical and pleasant to use and improve both efficiency and safety at work.

We draft the technical files and instruction manuals required for tools.

TECHNICAL CALCULATION

FINITE ELEMENT ANALYSIS AND COMPUTATIONAL FLUID DYNAMICS

Finite Element Method (FEM) and Computational Fluid Dynamics (CFD) are methods to establish the strength, functionality and behaviour of an item. Careful calculation in the planning phase will draw attention to possible problems, eliminating the need for corrections at a later stage.

Our experts know the practices and standards of the industry like the back of their hands. In addition to which, they have dozens of years of combined experience from thousands of projects, ensuring that they will find the optimal solutions to your needs. Our specialties include calculations related to paper machines, cranes, earthquakes, pressure equipment and piping.

 

PRESSURE EQUIPMENT CALCULATION

We can dimension, model and calculate pressure equipment and piping according to the relevant standards. We can also carry out your pressure equipment alteration plans and R&D activities, including any reports needed for relevant approvals.

Whether calculations are related to the R&D activities of a new product or refining existing ones, we support our customers in improving their products. We can conduct brief inspections and comprehensive calculations for complex units at the highest level of expertise.

The calculation software we use include ANSYS, Femap, Finnsap, SolidWorks Simulation VVD and OpenFOAM.

LIFTING AND HOISTING ACCESSORY ENGINEERING

SAFE HOISTING

In Lifting and hoisting accessory engineering, we offer a turnkey solution for our customers by combining the skills of our mechanical planning, Finite Element Method and safety experts into one package.

TANK AND CONTAINER ENGINEERING

TAILORED SOLUTIONS

We provide manufacturing drawings for containers of all sizes. We pay special attention to the characteristics and requirements of the materials to be stored in the container when planning the containers and connections and in material selections and manufacturing processes. The requirements applicable to the container and its surroundings according to relevant standards in terms of ground, wind conditions and earthquakes are taken into account in planning.

SHEET METAL ENGINEERING

COST-EFFECTIVE DESIGN

We design complex and demanding sheet steel and aluminium products to meet our customers’ needs.

In addition to intended use, we also pay special attention to the sheet steel material selections, methods of manufacturing and joints when designing sheet metal products as these factors differ from the usual methods used in mechanical planning.

We take responsibility for the cost effective planning, selection of manufacturing method and tendering for suppliers for our customers’ sheet metal products.

CASTING ENGINEERING

CASTINGS THAT CONVINCE

We design all kinds of castings to meet our customers’ needs. We specialise in the concept and implementation planning of iron and steel casting projects.

We plan both new castings and existing items that require some further development. Welded assemblies can also be designed as castings. The implementation of highly demanding castings that will be subjected to high levels of stress is always planned in collaboration with FEM calculation and manufacturing experts, while keeping the perspective of the casting and machining processes in mind.

We always draft production drawings and documentation that concern quality specifications according to the latest applicable standards.
