Custom Assembly Services for Production-Ready Products
Bring custom-manufactured parts, purchased hardware and controlled work instructions into one assembly workflow. Mockup coordinates preparation, joining, verification and packaging so product teams manage the result—not a chain of disconnected suppliers.
- Prototype subassemblies through repeat builds
- Mechanical joining, bonding and hardware installation
- Inspection and functional checks by agreed plan
Share the BOM, drawings, assembly model, work instructions, quantity, test requirements and packaging expectations. We will review sourcing boundaries, process risks and acceptance criteria.

01 / WHY INTEGRATED ASSEMBLY
Reduce Handoffs Between Part Quality and Product Function
A dimensionally acceptable component can still fail in assembly because of stack-up, orientation, finish buildup, missing hardware, torque, contamination or unclear work instructions. Integrated assembly keeps manufacturing, incoming control, joining and final verification connected.
- ✓One controlled route
Keep part manufacture, hardware, joining and release requirements connected.
- ✓Assembly feedback
Identify stack-up, orientation and access risks before repeat builds.
- ✓Defined acceptance
Connect dimensions, fit, function and packaging to one approved plan.
02 / ASSEMBLY CAPABILITIES
Choose the Right Assembly Route for the Product
Joining method, sequence, fixtures and verification are selected around the released design and product risk.

Packaging & Kitting
Protective packaging, labeled kits, serialization and shipment configuration according to the agreed release specification.
03 / PROGRAM SCOPE
Define Who Supplies, Verifies and Owns Every Item
The quotation and approved assembly plan should clearly assign sourcing, control, change authority, testing and release responsibility.

04 / ASSEMBLY WORKFLOW
From Released BOM to Verified Build
Each stage follows the approved revision, work instructions and acceptance plan.
Define
Review BOM, CAD, drawings, revisions, sourcing boundaries and acceptance criteria.
Prepare
Inspect and clean parts, verify hardware, then develop fixtures and work instructions.
Assemble
Execute the controlled sequence with approved tools, torque, bonding or joining parameters.
Verify
Check dimensions, fit, motion, appearance and agreed functional tests.
Pack & Release
Label, serialize, protect and preserve agreed build and test records.
05 / QUALITY & TESTING
Verify the Assembly—not Only the Components
Controls are selected around the product risk and approved acceptance plan. Test method, sample size, equipment and limits require agreement before the build.

- ✓Incoming and first-assembly inspection
- ✓Torque and adhesive-cure records
- ✓Weld and cosmetic inspection
- ✓Fit, motion and stack-up verification
- ✓Leak, pressure or basic electrical tests by approved procedure
- ✓Final audit and release records
06 / PARTS MADE AND ASSEMBLED
Connect Part Production Directly to Assembly
Mockup can coordinate multiple manufacturing routes and purchased hardware within one controlled project. For externally produced parts, incoming condition, dimensional responsibility and nonconformance handling are agreed before work begins.
CNC Machining
Precision housings, fixtures, shafts, inserts and structural parts produced to the assembly datum strategy.
Sheet Metal Fabrication
Cut, formed, welded and finished enclosures, panels, frames and brackets prepared for hardware installation.
Molding & Casting
Molded, cast and overmolded components coordinated with inserts, mating features and cosmetic requirements.
3D Printing & Finishing
Printed prototypes, fixtures and low-volume parts prepared, finished and integrated into the approved build.
07 / ASSEMBLY DFM & DFA
Design the Product for a Controlled Build
Good DFA makes orientation, access, joining and verification easier to repeat.
Reduce part count
Remove unnecessary components and fastener variety.
Mistake-proof orientation
Use self-locating features and clear assembly direction.
Provide tool access
Leave practical access for fasteners and joining operations.
Define joining parameters
State torque, locking, adhesive and cure requirements.
Control stack-up
Use practical datums, fixtures and gauges for critical relationships.
Protect cosmetic surfaces
Plan handling and fixtures around customer-facing areas.
Review serviceability
Account for replacement needs before choosing permanent joining.
Make tests measurable
Define clear equipment, conditions and pass/fail limits.
Frequently Asked Questions
Can Mockup source purchased components?+
Purchased components may be sourced after project review. The approved vendor list, substitute rules, traceability and commercial responsibility must be defined before release.
Can you assemble customer-supplied parts?+
Customer-supplied parts may be accepted subject to incoming-condition review. Inspection and responsibility for nonconforming supplied components are agreed before work begins.
What assembly methods are available?+
Mechanical fastening, press fits, inserts, riveting, bonding, welding and selected electrical or box-build operations may be supported after exact scope review.
Do you provide functional testing?+
Tests can be performed to an approved procedure with defined equipment and pass/fail limits. Product certification is not implied unless specifically contracted.
What files are needed?+
Provide the BOM, 3D assembly, component drawings, work instructions, approved supplier information, quantity, test procedure and packaging specification.
Can Mockup manufacture the parts and assemble them?+
Yes, where capability and project scope are confirmed. Keeping manufacturing and assembly connected helps surface fit, finish and stack-up risks earlier.
