Dot-peen Part Traceability Marking Equipment

Buy a marking process, not only a marking head

Dot-peen equipment creates an identification pattern by moving an impacting stylus across a part. The procurement problem includes access to the marking location, support of the part, the required symbol and the record behind that symbol. It is therefore different from buying a finished drilling tool. A portable machine can be taken to the component; a bench arrangement can be organized around repeated parts and fixtures. The selected route should follow the part-handling and traceability problem, not a model-family name alone.

Portable reference: e-TOUCH EVO

SIC's e-TOUCH EVO is a corded portable dot-peen gun with a 60×25 mm marking window. The linked technical sheet lists 100 W power and a 5 m power cable. The manufacturer describes tungsten-carbide marking of text, logos and DataMatrix codes, with optional support faces and a column base. Confirm which supports and reader options are included. Do not call this a cordless e-MARK or transfer a larger XL window to it. The current webpage and linked sheet disagree on weight and overall dimensions; obtain the current configuration drawing before planning handling or access.

Bench-top pneumatic reference: DBG-2-T1180

Huapu's DBG-2-T series detail identifies DBG-2-T1180 and a standard 110×80 mm marking area. It lists 1–3 characters per second specifically for 4×4 mm characters, and a marking depth of no more than 0.3 mm, dependent on material. Its published pneumatic supply range is 0.2–0.6 MPa. These are conditional catalogue figures, not a guaranteed DataMatrix cycle time or a depth requirement suitable for every component. The same technical block lists 400 W, AC 100–240 V ±10%, 50–60 Hz and a 0–40°C environment; the available air consumption is not specified.

Define traceability beyond visible characters

The enquiry should state where serial numbers originate, which fields are fixed or variable, what prevents duplicate identifiers and how a failed or unreadable mark is handled. Ask whether the system only makes the mark or also reads and verifies it against an agreed rule. SIC describes mark/read/database workflows, while Huapu describes fixture control and data interfaces, including computer-mediated serial or network communication. Those statements do not prove that a particular MES can be connected without development. Specify the protocol, record structure, permissions and acceptance test as project deliverables.

Qualify the mark on the actual part

Provide a drawing or representative sample, material and hardness, surface condition, coating sequence, curvature, access and required character or code size. Ask the component owner to define the allowed marking location and any depth or integrity restrictions. Request trials showing readability after the relevant manufacturing steps and inspection method. A manufacturer's maximum-depth statement is not authorization to indent a pressure-retaining component. Include the agreed fixture, positioning and process settings in the representative-part acceptance documentation.

Evidence and delivery boundary

SIC's self-published safety-valve case illustrates why different parts can need different marking technologies and a shared data workflow; it is not oilfield process approval for these two models. The quotation should identify the machine, controller, software, supports, air/power requirements, reader and integration work separately. Agree a representative-part acceptance run and the documents to be delivered. This reference does not promise oilfield certification, a qualified marking procedure, stocked equipment or manufacturer authorization.
