We are at your side

Together with you, we develop the best possible solutions to realise your project. 

Special components

Together with you, we develop the best possible solution to realize your project. We support you with our customized special components and assemblies. We offer you the greatest possible flexibility within any product line - from individual vacuum chambers, sight glasses and special flanges to customized electrical and mechanical feedthroughs. All special components are customised exactly to the customer's needs. Our vacuum experts are always in contact with you to review your requirements, design and provide technical advice.

Unique components are our specialty

Demanding vacuum technology applications require highly specialised parts and components. We realise components up to complex vacuum chambers according to your specifications. They are designed for use up to extreme high vacuum. Our experts are at your disposal for design and implementation. With their experience from many customer projects, they plan and manufacture your specific solutions. Our state-of-the-art production centre and our separate component cleaning facility VACOM cleanFAB® are available for your order. Benefit by the complete production process from a single source: from machining, welding, surface treatment and quality inspection to ultra-fine cleaning as well as packaging suitable for cleanrooms.


Reliable precision across all dimensions: mechanical manufacturing at its best

We use 3- and 5-axis precision milling centres. This allows us to machine chambers and special components up to dimensions of 2600 x 1100 x 900 mm3 (102,362 x 43,307 x 35,433 in). We can produce turned parts up to 550 mm (21,653 in) in diameter. In mechanical production, adaptive milling takes into account the real geometry of moulded components. Our CNC-controlled milling machines can produce any component from a full moulded part to a cube. The position of outlets and ports among each other as well as the precise positioning of focal points and beam guides can be realised within the tightest tolerances. Our quality assurance guarantee continuous monitoring of dimensional accuracy and tolerances. Finally, we check complex geometries with 3D coordinate measuring technology and the surface quality with tactile measuring methods to guarantee the specifications of your order. You receive a customised special part from us, fully compatible with other vacuum components. Our designs comply with the typical industry flange standards of KF, CF, QCF and ISO standards: DIN 28403, DIN 28404, ISO 3669-2.


Leading the goal with optimized materials and surfaces

Choose the right material for your application. We have experience in welding stainless steels and aluminium of various qualities. For processing your special components, we use stainless steels with optimal vacuum properties. When manufacturing our vacuum chambers from aluminium (AluVaC®), the welding seams are executed to the usual high quality in special processes by certified experts. VACOM-own stainless steel 1.4429-ESU (316LN ESR) is specially produced for demanding vacuum applications. This is particularly pure and homogeneous. It has high hardness and low permeability. For your component requirements, we use various welding processes depending on the welding geometries and component thicknesses. These include TIG, orbital, laser and microplasma welding. This enables us to manufacture very fine to solid components according to specifications. For surface treatment, we use specified processes with defined results. We offer mechanically and chemically untreated surfaces, mechanical polishing, pickling, glass bead blasting and electropolishing. Do you have any questions about alternative surface treatment processes? We will be happy to discuss these with you.
