Contract manufacturing

Exentec provides contract manufacturing for high-purity systems and complex assemblies used in critical process equipment. We combine engineering support, controlled manufacturing, testing, cleaning and delivery preparation in one accountable model. Helping OEMs and technology leaders move from concept or approved design to reliable production.

For applications involving gases, chemicals, vacuum, cooling media and other high-purity fluids, the quality of every assembly matters. Material selection, joining methods, cleanliness, test coverage, documentation and packaging all influence how confidently equipment can be integrated, commissioned and operated. Exentec helps customers manage these requirements as one coordinated manufacturing process rather than a chain of disconnected suppliers.

Precision contract manufacturing for critical process equipment

Contract manufacturing in critical environments is more than producing individual parts. It is the controlled transfer of a technical requirement into a repeatable, production-ready assembly—manufactured to defined specifications and prepared for dependable use in demanding operating conditions.

Exentec supports customers that require precise supply, dosing, mixing or distribution of high-purity media. Whether the requirement is a build-to-print assembly, an integrated module, a gas mixing system or a specialised vacuum component, our teams focus on the factors that protect quality, safety, functionality and delivery confidence.

What Exentec manufactures

Our contract manufacturing scope includes individual assemblies, integrated modules and production-ready systems. Typical examples include:

• Gas, vacuum and cooling pipes
• Automated gas mixing systems and gas sticks
• Pipe, bellow and valve assemblies with high-purity-compliant connectors
• Connecting components, distribution blocks and hoses
• Cable sets and integrated electrical assemblies
• Modular plug-and-play solutions
• EUV components for vacuum applications

The right scope is determined by the customer’s technical specification, production volume, cleanliness requirements, quality plan and delivery model. Exentec can support a defined assembly or a broader manufacturing package that combines engineering, production, testing and finishing. 

One accountable partner from concept to qualified production

Exentec's contract manufacturing model brings engineering, manufacturing, testing and cleanroom finishing together in one controlled delivery model. This reduces supplier interfaces, simplifies coordination and creates a clearer path from technical requirement to production release. Whether the requirement begins with an early-stage concept, a defined technical package or a build-to-print specification, Exentec supports the work required to deliver high-purity assemblies that are ready for qualification, integration and scalable production.

Engineering and design support

Exentec engineers and designers help customers translate functional, cleanliness and performance requirements into practical manufacturing solutions. Support can begin with feasibility studies, process engineering, component selection and design-for-manufacture input - helping identify production, test and supply-chain considerations before release:

• Process engineering and component selection
• Mechanical and electrical design support
• Feasibility checks and design-for-manufacture input
• Failure mode and effects analysis (FMEA) support
• Tooling and test-concept development
• Project management and technical documentation
• Release planning for prototype, repeat and volume requirements
• Spare-parts and lifecycle support planning

Early support helps OEMs reduce late-stage redesign, avoid avoidable manufacturing interfaces and establish a more reliable route from prototype to repeatable production.

Build-to-print manufacturing

When the design is defined, Exentec provides build-to-print manufacturing for high-purity gas, chemical, vacuum, cooling and fluid assemblies. Manufacturing can support prototype builds, low-volume programs, configuration variants and repeatable series production. The focus is not simply on producing a component. It is on manufacturing assemblies in a way that supports quality, traceability, delivery certainty and integration readiness:

• Orbital and manual TIG welding
• Mechanical and electrical assembly
• High-purity tube bending and formed assemblies
• Laser coding and component identification
• Manufacturing and assembly in ISO 6 and ISO 7 cleanroom environments
• Qualified supplier-network management for machining, sheet-metal fabrication, welding, additive manufacturing and specialist parts
• Technical product support through production ramp-up
• Documentation and release preparation for volume production

From a defined drawing package to a qualified, repeatable assembly, Exentec combines in-house process knowledge with controlled supplier coordination to help reduce manufacturing risk and simplify supply-chain management.

Testing, qualification and documentation

Quality is built into the manufacturing process, not inspected in at the end. Exentec can define and execute inspection and test plans appropriate to the application, media, materials, cleanliness requirements and functional performance criteria. Testing should be positioned as a decision-maker benefit as well as a technical capability: it reduces the risk of receiving an assembly that creates qualification delays, rework or installation issues at the customer site.

• First-article inspections
• Visual and dimensional inspection
• Endoscopic inspection for internal quality checks
• Vacuum leak testing
• Pressure and high-pressure testing
• Particle testing
• UV and white-light inspection
• Flow and lifetime testing
• Electrical and functional testing
• Test-rig and test-method development where required
• Test documentation, release records and traceability support

Defined testing, documented results and traceable release procedures give engineering, quality and operations teams greater confidence that assemblies are ready for qualification, handover and long-term production use.

Cleanroom finishing and delivery readiness

For high-purity equipment, final cleaning, packaging and handling are part of product quality - not an afterthought. Exentec provides finishing and delivery-preparation processes designed to protect assemblies through transport and reduce integration effort at the customer site.

• UHP fine cleaning
• Laser cleaning
• Electropolishing where required
• Cleanroom finishing in ISO 6 and ISO 7 environments
• Cleanroom packaging and labelling
• Defined packaging concepts for sensitive assemblies
• Reusable packaging concepts where appropriate
• Delivery preparation aligned with handling, installation and traceability requirements

The result is a high-purity assembly that arrives protected, identified, documented and prepared for efficient integration into the customer’s equipment or facility.

Designed for demanding high-tech industries

Semiconductor and electronics

In semiconductor manufacturing, process stability depends on precise and reliable handling of high-purity gases, chemicals and vacuum systems. Exentec supports equipment manufacturers and technology partners with assemblies and systems for demanding cleanroom and sub-fab applications, including gas supply, gas mixing, vacuum and EUV-related components.

Biopharma and life sciences

Biopharma and life-science equipment requires disciplined control of materials, cleanliness, documentation and functional performance. Exentec supports high-purity equipment assemblies used in controlled and regulated production environments, helping customers reduce complexity between engineering, manufacturing, testing and delivery preparation.

Data centers and critical infrastructure

For data-center infrastructure and other critical facilities, equipment reliability, delivery certainty and installation readiness are essential. Exentec supports OEMs and infrastructure partners with engineered assemblies where controlled fabrication, defined testing, traceability and scalable production can reduce project risk and simplify integration.

Other advanced manufacturing applications

Exentec also supports customers in battery, electronics, vacuum technology and other advanced-manufacturing sectors where high-purity media, specialist assemblies and dependable execution are central to process performance.

Quality, cleanliness and traceability built into every assembly

High-purity equipment cannot rely on a one-size-fits-all manufacturing process. Every project must account for the media being handled, the operating environment, the required materials, joining methods, cleanliness level, test plan and documentation requirements. Exentec integrates these requirements into the manufacturing process through controlled assembly, qualified cleaning and finishing, inspection and testing, and documented release procedures. The objective is straightforward: deliver assemblies that are ready to perform within the customer’s equipment, process environment and production schedule.
