| Process | Best For | Typical Volume | Tooling | Lead-Time Pattern | Key Advantage |
|---|---|---|---|---|---|
| CNC Machining | Critical fits & complex features | Prototype to repeat batches | Fixtures as needed | Setup & machining time | No production mold |
| Sheet Metal Fabrication | Enclosures & brackets | Prototype to repeat batches | Process-dependent | Cutting, forming & finish | Efficient formed structures |
| Injection Molding | Repeat plastic components | Tooling-led production | Mold required | Tooling & sample approval | Repeatable molded features |
| Die Casting | Repeat metal housings | Tooling-led production | Die required | Tooling & sample approval | Near-net shape parts |
| 3D Printing | Geometry & fit validation | Prototypes & small batches | No production mold | Build & post-processing | Complex forms without molds |

DFM Review
Review tool access, wall thickness, draft and assembly interfaces before production. Resolve features that could add avoidable cost or rework.
Tolerance Review
Our engineers review critical dimensions and suggest achievable tolerances based on the chosen manufacturing process.
Material & Process Selection
Compare material grades and processes against load, temperature, corrosion exposure, appearance and expected order quantities.
Cost-Down Review
Review setups, deep pockets, specified tolerances and finishing steps. Compare practical alternatives while preserving your functional requirements.
Quality & Traceability
ISO 9001:2015
Our facilities operate under a strict ISO 9001 certified quality management system to ensure consistent results.
CMM Inspection & FAI
We utilize Coordinate Measuring Machines (CMM) for precise verification and can provide comprehensive First Article Inspection (FAI) reports.
Material Traceability (CoC / MTR)
Specify any CoC, material certificate and lot-traceability requirements with your RFQ so availability and documentation can be agreed before ordering.
Final Inspection
Agree critical dimensions, cosmetic criteria, sampling and packaging before production. Review the required inspection records before shipment.
Sample Approval & Revision Control
Agree the drawing revision, first-article acceptance criteria and approval point before repeat production. Identify any design changes in your purchase order so parts and inspection records stay aligned.

Manufacturing Services FAQs
What manufacturing processes does LK MFG support?
Our custom manufacturing services include CNC machining, sheet metal fabrication, plastic injection molding, die casting and 3D printing. Share your geometry, material and quantities so we can compare suitable processes and any finishing or assembly needs.
What CAD files can I send?
Send a STEP or IGES model and a PDF drawing with dimensions, threads, finish and revision. STL is useful for 3D printing; DXF is useful for flat profiles. Include quantity, material grade and delivery location so the quotation covers the same scope you expect.
Can you support prototypes and production?
Yes. Use rapid prototypes to check fit and function, then agree the pilot batch, tooling and inspection plan for repeat production. The most suitable process may change as your quantities and design maturity increase.
What materials do you support?
Options include aluminum, stainless steel, brass, titanium and engineering plastics such as ABS, PC, nylon, POM and PEEK. Grade availability depends on the process. Tell us about load, heat, corrosion and cosmetic requirements before selecting a material.
What tolerances can you support?
Tolerance capability depends on geometry, size, material, process and finish. Mark critical dimensions and datums on your drawing. We review achievable tolerances and the inspection method before confirming the quotation, rather than applying one tolerance to every part.
Do you provide DFM feedback?
Yes. DFM review can highlight tool access, wall thickness, draft, bend geometry and costly tolerances. We discuss proposed changes with you before manufacturing; your approved drawing remains the production reference.
Can you provide FAI / CMM documentation?
Include the required FAI, CMM measurements, material certificates and acceptance criteria in your RFQ. We agree the inspection scope, report format and any additional cost before the order is released.
Can you sign an NDA?
An NDA can be arranged before you share confidential drawings. Contact our team first if your project requires an agreement or a specific file-transfer process.
How quickly do you respond to RFQs?
We aim to respond within 24 hours. A firm quotation may need further review for complex tooling, special materials or assemblies. Supplying the drawing revision, material, quantity, finish and target delivery date helps reduce follow-up questions.
How do you support U.S. logistics?
Our Dallas-area team can coordinate project communication, delivery and agreed inventory programs with manufacturing in China. Ask for the shipping method, delivery terms and any duties or taxes to be stated in your quotation.
