PART MARKING CAPABILITIES & PROCESS ADVANTAGES
MIL provides a complete suite of precision marking methods used to apply required manufacturing details—including serial numbers, part numbers, lot codes, date codes, and traceability identifiers. Each marking method is selected based on material, durability needs, production environment, and specification requirements.
Spec & Capability Highlights
- Permanent and semi-permanent marking methods for metals and coated surfaces
- Ideal for serialized identification, traceability, inventory control, and regulatory compliance
- Marking on flat, contoured, machined, anodized, painted, or plated components
- High-precision text and symbols in various sizes, colors, and marking depths
- Supports aerospace, medical, defense, and industrial marking requirements

Material-Engraving & Indentation Methods
Vibro Peen Marking (Manual & Automated)
A durable marking method that uses a vibration-driven tool to indent characters into the surface. Ideal for permanent identification on hardened, coated, or machined materials.
Ink, Paint & Color-Contrast Methods
Silkscreen / Screen Printing
A stencil-based marking process that produces high-contrast, precise graphics and text in a range of sizes and colors. Ideal for logos, symbols, labels, and multi-color markings.
Fill Marking
Engraved, embossed, or recessed characters are filled with ink or paint to create durable, highly visible identification.
Rubber Stamp Marking
Ink stamp markings commonly used for temporary identification or inventory control; can be overcoated with lacquer or polyurethane for added durability.
How the Part Marking Process Works
Step 1 — Determine Required Marking Method
Material, surface finish, regulatory requirements, and the intended use of the part determine which marking process will be applied.
Step 2 — Surface Preparation & Fixturing
Parts are cleaned and properly fixtured to ensure accurate placement, clean lines, and consistent marking results.
Step 3 — Marking Application
The selected method—vibro peen, silkscreen printing, fill marking, or stamping—is applied according to customer specifications, drawings, or industry standards.
Step 4 — Inspection & Verification
Markings undergo inspection for clarity, legibility, adhesion (when applicable), and specification compliance to ensure long-term readability.
Why Work With MIL for Part Marking?
Precision, Consistency & Traceability
MIL delivers clear, consistent, and durable markings that meet strict industry standards for traceability and identification.
Experience with Complex Materials & Surface Finishes
Our marking methods accommodate anodized, plated, painted, coated, and machined surfaces without compromising finish quality.
Integrated with Coating & Finishing Services
Part marking is performed in the same facility as metal finishing, coatings, and NDT—streamlining workflows and reducing turnaround time.
Built for High-Reliability Components
Our marking processes support regulated industries where identification accuracy and durability are essential for compliance and safety.

FAQs
Turnaround varies by marking method and part volume, but MIL supports both rapid prototype needs and production-scale workflows.
Typical timelines:
- Vibro peen / indentation marking: Same day to 1–2 days
- Silkscreen / screen printing: 2–4 days (setup, fixturing, and curing time may apply)
- Fill marking: Usually 1–3 days depending on complexity
- Rubber stamp marking: Same day for most parts
Rush requests can often be accommodated when parts are already in-house for other processes such as anodize, coating, or NDT.
No—MIL selects the marking process based on the finished surface to ensure no damage, abrasion, or loss of coating performance.
- Vibro peen: Never applied to surfaces where it would compromise dimensional or cosmetic requirements.
- Silkscreen / ink marking: Ideal for anodize, chem film, powder coat, and painted surfaces.
- Fill marking: Used only when recesses exist and will not impact coating integrity.
Our technicians review drawings and specifications to select the most appropriate marking method for each surface type.
Yes. MIL can produce UID/IUID-compliant markings and labels, and we support:
- Data matrix marking formats
- Verification of mark quality
- Documentation required for IUID compliance
For parts requiring formal registration, MIL can assist or supply the necessary quality verification for customer-side submission.
MIL can mark a wide range of components, from very small machined parts to larger housings, brackets, plates, and assemblies.
- Vibro peen and stamping: Suitable for small to medium-sized parts
- Silkscreen: Supports relatively large, flat, or contoured surfaces
- Fixturing and marking area limits depend on part geometry
Submitting a drawing or photo ensures quick confirmation of size compatibility.
Yes. MIL provides verification and documentation upon request, including:
- Contrast checks
- Legibility and character depth validation
- Cell fill and quiet-zone verification for UID/IUID
- Adhesion checks for ink- or paint-based markings
- Spec compliance statements for regulated industries
These reports support aerospace, defense, medical, and OEM quality requirements.
Yes. MIL’s marking team regularly works with coated, anodized, plated, and flight-critical components where no rework or surface disturbance is permitted.
We ensure:
- Correct fixturing and pressure control
- Non-abrasive contact with finished surfaces
- Process selection that avoids mechanical impact when prohibited
- Strict adherence to customer and prime specifications
Marking can be completed as a last step in the processing chain with no risk to the underlying finish.
