Openex Metal Fabrication provides custom metal fabrication, large CNC machining, welded assemblies, and dimensional inspection for industrial OEMs and specialized equipment manufacturers. For aerospace and defense-related projects, our team can review structural components, equipment frames, machined housings, ground support structures, and test equipment against customer drawings and project specifications.
Manufacturing scope is defined by the component design, material, dimensions, tolerances, production quantity, applicable standards, inspection plan, and delivery requirements. Where technically appropriate, fabrication, stress relief, machining, assembly, and inspection can be coordinated within one manufacturing program.
Project Applications
The following categories describe potential manufacturing applications. Final acceptance depends on engineering review, production capability, applicable qualifications, and the customer's quality requirements.
Custom housings, equipment bases, mounting structures, brackets, and other metal components manufactured to customer drawings. Material selection, machining strategy, datum references, and inspection requirements are reviewed before production.
Explore heavy CNC machining →
Fabricated equipment structures, test-system frames, precision interfaces, and large machined bases. For vacuum, thermal, pressure, or other specialized test equipment, define the operating conditions and acceptance criteria at the quotation stage.
Explore metal fabrication →
Large welded frames, equipment supports, transport structures, access platforms, and other heavy assemblies. Project review considers structural drawings, load cases supplied by the customer, weld requirements, dimensional control, coating, and transport constraints.
Review fabrication capabilities →
Components that require a combination of plate processing, forming, welding, stress relief, precision machining, assembly, and final inspection. The sequence is selected to suit the geometry, material, distortion risks, and required finished dimensions.
Explore heat treatment and finishing →From Drawing to Delivery
For complex metal components, process planning and inspection requirements should be agreed before manufacturing begins. The applicable steps depend on the component and contract scope.
Review geometry, dimensions, material, quantities, critical features, tolerances, standards, and delivery requirements.
Establish the proposed cutting, forming, welding, machining, heat-treatment, and finishing sequence where applicable.
Manufacture the structure or assembly in accordance with the approved drawings, specified welding requirements, and agreed process controls.
Where required by the design or process plan, manage distortion risks through suitable treatment and machine critical surfaces and interfaces.
Complete the agreed dimensional checks, material verification, and specified non-destructive testing. Records depend on the inspection plan and contractual requirements.
Coordinate approved finishing, packaging, lifting, and transport planning around component dimensions, weight, protection requirements, and destination.
Material Selection
Aerospace-related components may call for aluminum alloys, titanium, stainless steel, nickel-based alloys, or other specified metals. Each material brings different machining, forming, welding, heat-treatment, and inspection considerations.
Openex reviews the specified grade and condition against the proposed manufacturing route. Material substitutions should only be considered when expressly permitted and approved by the customer or responsible design authority.
Explore the materials center →| Material family | Points to review |
|---|---|
| Aluminum alloys | Specified grade and temper, dimensional stability, thin-wall distortion, and surface requirements. |
| Titanium alloys | Grade-specific machining strategy, heat generation, tooling, workholding, and any specified joining procedures. |
| Nickel-based alloys | Work hardening, cutting forces, thermal management, tool wear, and specified heat-resistant properties. |
| Stainless and alloy steels | Strength and hardness condition, weldability where relevant, corrosion requirements, and inspection criteria. |
Quality and Traceability
Aerospace and defense procurement can involve specific requirements for material traceability, process qualification, dimensional verification, non-destructive testing, and manufacturing records. These requirements should be stated in the RFQ and agreed before an order is accepted.
Required material grades, certificates, identification, and traceability scope.
Critical dimensions, datums, geometric tolerances, measurement methods, and report format.
Applicable welding codes, procedure requirements, test methods, acceptance criteria, and reporting.
Inspection stages, customer witness or hold points, nonconformance handling, and final documentation package.
Required certifications, customer approvals, jurisdictional restrictions, and authorized technical-data handling.
Frequently Asked Questions
Openex reviews custom metal components and assemblies such as large structural parts, equipment frames, machined housings, test fixtures, ground support structures, and specialized welded assemblies. Feasibility depends on the design, material, dimensions, tolerances, inspection requirements, and applicable project standards.
Yes. Where the design and project requirements allow, manufacturing can combine cutting, forming, welding, stress relief, CNC machining, assembly, finishing, and dimensional inspection. The proposed manufacturing route is reviewed against the component drawings and acceptance criteria.
Depending on the project scope and agreed quality plan, documentation may include material test reports, dimensional inspection reports, welding records, non-destructive testing reports, heat-treatment records, and other manufacturing records. Specify the required standards, inspection methods, and documentation before quotation.
Certification, registration, export-control, and controlled-data requirements must be verified for the specific project before work is accepted. Buyers should state all applicable requirements during initial contact. Do not send export-controlled or otherwise restricted technical data until Openex has confirmed an approved method for receiving and handling it.
Provide available 2D drawings or 3D models, material and grade, overall dimensions and weight, quantities, critical tolerances, applicable codes, inspection and traceability requirements, finishing specifications, target delivery date, and delivery destination. If some information is unavailable, contact Openex to discuss the initial feasibility review.
Openex operates a large-scale manufacturing facility with reported lifting capacity up to 250 tons. Its published facility information lists maximum CNC milling dimensions of 25,000 × 6,000 × 5,000 mm and vertical turning capacity up to 8,000 mm in diameter. Actual feasibility depends on the part, equipment allocation, handling requirements, and project scope.
