HELDECO manufactures sophisticated industrial components, welded assemblies, precision parts, and special solutions according to drawings. The typical products are large, heavy, or complex components, for which experience, stable processes, and thorough quality control are crucial.

HELDECO bearbeitet schwere Industriekomponenten mit einem Stückgewicht von bis zu 30 Tonnen. Je nach Fertigungsverfahren sind Fräsbearbeitungen bis zu einer Länge von rund 20 Metern sowie Drehbearbeitungen bis zu einem Durchmesser von 3,8 Metern und einer Drehlänge von 7 Metern möglich. Damit eignet sich HELDECO für Projekte, bei denen Standardfertigung nicht mehr ausreicht.

Both. HELDECO takes on individual parts, prototypes, spare parts, small series, and recurring series. The company is particularly strong in components with high requirements for dimensional accuracy, repeatability, and documentation.

Yes. HELDECO manufactures according to customer specifications, drawings, CAD data, and technical specifications. Clear details regarding material, tolerances, surfaces, testing requirements, and quantities are important.

For a technical enquiry, STEP/STP, IGES, DXF, DWG or comparable CAD and drawing data are helpful. It is crucial that geometry, tolerances and surfaces relevant to functionality are clearly visible.

Yes. Depending on the project, raw parts, welded constructions, or cast components are mechanically processed and prepared for further assembly.

Yes. Welded assemblies are among the typical applications. Important factors here are low stress levels, clean reference surfaces, well-thought-out fixturing, and a machining strategy that minimises distortion.

Drawings, CAD data, material, quantity, weight, desired tolerances, surface requirements and delivery date are usually checked. This is followed by technical and economic evaluation.

Ideally, the following are required: drawings, 3D data, material, raw part status, quantity, tolerances, testing requirements, surface specifications, documentation needs, and target date.

Depending on utilisation, material availability and complexity, short-term spare parts projects are possible. Particularly for critical industrial plants, rapid technical clarification is crucial.

HELDECO specialises in demanding industrial components where size, weight, precision, material behaviour, and project responsibility converge. This requires more than just machine capacity.

Depending on the requirements, measurement protocols, test reports, material certificates, and project-specific documentation are possible. The scope will be defined before the project starts.

Very important. Many costs, risks, and deadline problems arise during the design phase. Early coordination can significantly improve tolerances, clamping, material selection, and machining steps.

Yes. Depending on the project, components can be processed and documented in such a way that they can be directly integrated into assemblies, plants or further assembly steps.

A big role. For heavy components, clamping, temperature, material stresses, machining sequence, and inspection strategy are important. These factors cannot be solved by machine performance alone.

Materials processed include construction steel, alloy steel, stainless steel, duplex, super duplex, cast iron, aluminium, and special materials. Key considerations are application, load, surface requirements, and machinability.

When it comes to stainless steel, surface quality, heat development, tool selection, and clean machining parameters are crucial. Depending on the application, corrosion resistance and documentation play a central role.

Duplex and super duplex steels are demanding materials with high strength and corrosion resistance. Stable processes, appropriate tools, and experience with cutting parameters are crucial for machining.

Yes. Cast components require experience because allowances, structure, stresses, and surface condition can vary. Careful machining planning is therefore particularly important here.

High-strength steels place high demands on the tool, machine, clamping and process stability. Incorrect parameters can lead to tool wear, dimensional deviations or surface problems.

Internal stresses can lead to distortion after material removal. Therefore, machining sequence, stress-relieving annealing, allowances and interim measurements are important topics.

The raw part condition influences the entire manufacturing process. Welded constructions, castings, forgings, or flame-cut parts behave differently and must be planned accordingly.

Heat treatment can be useful for reducing stresses, adjusting material properties, or minimising distortion. Whether it is necessary depends on the material and the application.

Without precise material specifications, it is difficult to reliably assess machining strategies, tool selection, testing requirements, and costs. Standard designations and material certificates are therefore helpful.

Aluminium is generally easy to machine, but requires different strategies for chip formation, heat, clamping, and surface quality compared to steel or cast iron.

Typical components include shafts, rollers, housings, valve bodies, guide vane carriers, bearing housings, large flanges, machine beds, base plates, special constructions, and ready-to-assemble units.

A guide vane carrier is a central component in turbine and power plants. It accommodates guide vanes, directs flows, and must remain precise, stable, and resilient long-term.

Ventil housings require precise sealing surfaces, robust geometries, and clean connection areas. Errors directly affect function, leak-tightness, and lifespan.

When it comes to rolls and rollers, roundness, surface quality, dimensional accuracy, material behaviour, and load-bearing capacity are crucial. Stable manufacturing processes are particularly important in rolling mills, power plants, and mechanical engineering projects.

A machine bed is the load-bearing base of a machine. It must be stable, dimensionally accurate, and low-vibration so that guideways, axes, and assemblies can operate precisely and durably.

A bearing housing accommodates bearings and ensures their precise positioning. Fits, coaxiality, surface quality, and stable geometry are crucial.

A large flange connects large components, pipelines, housings or plant components. Flatness, hole patterns, sealing surfaces and load-bearing connection geometries are important.

A rotor is a rotating component that transmits forces, torques or flows. Depending on the application, concentricity, balance, material strength and surface quality are crucial.

A stator is a stationary counterpart to the rotor. In machines and turbines, it must be geometrically precise, stable, and functionally matched to the overall system.

A base plate serves as a supporting, aligning, or connecting structure. Flatness, hole patterns, mating surfaces, and rigidity are often crucial.

A special solution is a component or assembly that does not come from a standard catalogue but is developed and manufactured for a specific system, function, or load.

Yes. Spare parts for existing systems are often custom-made. Important factors here include inventory data, sample parts, drawings, or technical reconstruction.

Typical components for continuous operation include rollers, shafts, bearing housings, base plates, guides, holders, and other highly stressed machine parts.

Typical turbine components include casings, shafts, guide vane carriers, flanges, bearing areas, and supporting structures.

A high-performance component is a part that must function reliably under high mechanical, thermal, or dynamic stress. This requires precise manufacturing, suitable materials, and clear quality processes.

HELDECO manufactures for the energy, hydropower, wind power, gas turbine, heavy industry, plant and mechanical engineering, mobility, nuclear technology, aerospace, and food and pharmaceutical industries.

Depending on the project, components such as guide vane supports, housings, shafts, bearing areas, flanges, or other functionally critical components for energy plants are produced.

Wind power components must withstand high forces, dynamic loads, long service times, and tight tolerances. Manufacturing must therefore be robust, repeatable, and traceable.

Components for gas turbines are frequently exposed to high temperatures, pressures, vibrations, and material stresses. Precision, material expertise, and process reliability are crucial here.

In heavy industry, robust components, long service life, high load capacity, repairability and reliable supply capability are paramount. Downtime is expensive, so the component must work.

In plant engineering, HELDECO supplies project-specific components, assemblies, and special parts that must be precisely integrated into overall technical systems.

Depending on the application, load-bearing, rotating or connecting components are produced for vehicles, rail applications, plants and special machines within the mobility sector.

In food and pharmaceutical applications, material selection, cleanability, surface quality, corrosion resistance, and documented manufacturing are crucial.

Retrofit projects extend the lifespan of existing plants. For this purpose, spare parts, adapted components, or improved assemblies are manufactured, often without a complete modern dataset.

Regional manufacturing in Austria can improve coordination, quality assurance, response times, and project control. Proximity is often a real advantage, especially for complex components.

Yes. Early technical coordination helps to optimise manufacturability, processing strategy, material selection, costs, and schedule risks. This is particularly relevant for complex industrial components.

Costs are usually lowered not by cheaper manufacturing, but by better design, realistic tolerances, sensible clamping, suitable materials and clear testing requirements.

This depends on the geometry, material, clamping, measurability and application. Tight tolerances are possible but must be technically sound and economically justified.

Unnecessarily tight tolerances increase effort, costs and risk. Crucially, it is important which surfaces are actually functionally relevant and where standard tolerances are sufficient.

Distortion is reduced by appropriate raw part planning, heat treatment, machining sequence, symmetrical material removal, intermediate measurements, and stable clamping.

The clamping determines whether a component can be machined stably, accessibly, and with dimensional accuracy. For heavy components, it is often one of the most important success factors.

Functional machining means that manufacturing not only produces dimensions but also takes into account the later function of the component: sealing, concentricity, fit, assembly, and load-bearing.

A component should be designed so that critical dimensions and surfaces can be reliably checked. What cannot be meaningfully measured becomes a risk in quality assurance.

Ideally before the final drawing release. This allows the manufacturability, tolerances, material condition, testing concept, and processing sequence to be influenced meaningfully.

Design for Manufacturing means designing components in such a way that they can be manufactured reliably, economically, and reproducibly.

Documentation creates traceability. It is particularly relevant for safety-critical applications, international projects, audits, and later maintenance.

For prototypes, technical feasibility is the primary focus. For series components, repeatability, process stability, cycle time, and economic reproducibility are also important.

The right partner not only has suitable machinery but also experience with large workpieces, materials, clamping, testing, documentation, and project communication.

Important aspects include questions about references, component sizes, materials, quality documentation, timeline risks, measurement capabilities, project responsibility, and technical coordination.

For demanding components, errors, rework, delays, and downtime can be significantly more expensive than a seemingly cheaper offer price.

Risks include dimensional deviations, delays, missing documentation, scheduling problems, assembly problems, complaints, and in the worst case, plant shutdown.

A specialist is worthwhile if components are large, heavy, complex, functionally critical, require documentation, or are subject to tight deadlines.

On-time delivery is central to industrial projects because individual components often influence entire assembly or commissioning plans. Reliable planning is therefore a mark of quality.

Drawings, 3D models, materials, quantities, weights, target dates, tolerances, testing requirements, delivery conditions, and contact persons for technical queries should not be missing.

Technical competence is demonstrated through probing questions, feasibility assessments, suggestions for optimisation, realistic timelines, and sound risk management.
