Fertigungsablauf
CNC Machining Built Around Internal Passage Quality
The approved route connects material control, CNC-Bearbeitung , CNC milling, CNC turning, deep-hole machining, joining, cleaning and verification.
DFM & Material Release
Review ports, wall thickness, tool access, sealing geometry and inspection access. Verify the material certificate, grade, condition and blank size, plus any specified visual or nondestructive examination.
CNC-Bearbeitung
Mill multi-face geometry, turn cylindrical interfaces, drill controlled passages and finish threads, O-ring grooves and sealing faces.
Joining & Finishing
Apply the approved welding, brazing or mechanical assembly route, followed by passivation, electropolishing, anodizing or the specified finish.
Deburring & Cleaning
Remove cross-hole burrs, chips, cutting fluid and joining residue. Rinse, dry and protect every fluid-contact passage.
Verification & Delivery
Inspect dimensions and complete the approved leakage, pressure, flow or cleanliness tests before controlled packaging.
Weldo Manufacturing Capability
Machining Envelope and Tolerance Capability
Use these ranges for RFQ screening. Material, manifold geometry, feature depth, tool access, fixturing and inspection determine the released capability.
Multi-Face CNC Milling
Machine external geometry, sealing faces, ports, brackets and intersecting features from controlled datums.
CNC Turning & Port Machining
Produce concentric end fittings, adapters, threads and sealing interfaces for reliable assembly.
Deep-Hole Passage Control
Plan drilling direction, chip evacuation and cross-hole intersections around internal cleanliness.
Joining & Post-Processing

Maximum turning capacity
For round bodies, fittings and tubular components.
General tolerance classes
Selected by material, nominal size and released drawing.
Standard-Maßtoleranz

Reference minimum wall

As-machined surface roughness
Feature, cutting direction and material dependent.
Selected sealing-face roughness
Specified from seal type, pressure and leakage requirement.
Maximum envelope describes machine travel rather than a guaranteed usable part size. ISO 2768 applies only when stated on the drawing; drawing-specific tolerances and GD&T take precedence.

FAQ
Questions Beyond the Manufacturing Overview
What is the difference between a water manifold and a hydraulic manifold? +
A water manifold distributes water or coolant through cooling and process circuits. A hydraulic manifold integrates valve cavities and control passages for hydraulic-fluid power and control. Media compatibility, operating pressure, sealing, cleanliness and validation requirements differ by system.
Can Weldo reproduce an obsolete manifold without the original drawings? +
Yes. Reverse engineering starts with sample inspection, dimensional capture and interface verification. Operating pressure, fluid, temperature and functional requirements complete the controlled replacement specification.
How are design changes controlled after first-article approval? +
Every change receives a controlled drawing revision. Changes to materials, ports, passages, sealing features or testing trigger a new DFM review and the corresponding revalidation.
What documents are supplied with an order? +
The purchase specification defines the document package. It includes the requested material certificates, dimensional reports, test records, surface-treatment records and batch traceability.
How should a water manifold be maintained? +
Maintenance follows operating data and the approved service plan. Routine checks cover leakage, corrosion, pressure, temperature, flow, filter condition and coolant chemistry. Internal service starts only after isolation, pressure release and drainage.
Can customer-specified valves, sensors and quick disconnects be installed? +
Yes. Assembly follows the approved component model, port standard, sealing material, pressure rating, temperature rating and installation procedure.
