Fabricators are increasingly incorporating marking solutions into their production processes, whether for traceability of products in the automotive or aerospace sectors, for example. Or in the production process itself, marking components to identify them for assembly and then covering the marks on the finished product with paint, for instance. For some manufacturers, they require their marking systems to leave visible marks after coating is completed. Identification lowers the chance of costly mistakes and wasting valuable production time.

Marking systems range from portable options to machines with small footprints that can fit into tight spaces. Read on to learn about product options that would best suit your machine shop.

VARIETY OF SIZES AND POWER CLASSES PROVIDE THE OPTIMAL DEVICE FOR EVERY MARKING TASK

UNIQUE MARK: PICOSECOND LASER MARKING IS RESISTANT TO CORROSION

Amada Weld Tech Inc. (Monrovia, CA) now offers black, corrosion-resistant marking capability for the medical device manufacturing industry. This unique mark, frequently used for stainless steel implantable devices and surgical tools (e.g., banding around trocars or UDI marking on surgical scalpels) survives multiple passivation and autoclaving cycles.

This black mark is generated using a picosecond laser. The ultrashort pulse durations of the picosecond laser allow it to impart energy to a material surface with almost no thermal effect. Unlike the heat-generated annealed marks made with fiber lasers, marks created by picosecond IR lasers are extremely high contrast periodic nanostructures with antireflective properties that make the marks appear deep black against their surroundings. The marks are restructured surface material rather than an oxide layer, making them resistant to bacterial growth, passivation, corrosion and autoclaving. What’s more, the processing window for developing the marks on stainless steels, aluminum and titanium is wider than that of traditional fiber lasers. Picosecond lasers also offer marking capabilities on polymers often used in medical devices.

The picosecond laser is integrated into bespoke CDRH Class 1 systems that are designed for a specific part or range of parts. System features may include a galvo scanning head, a bar code scanner for job load, four or more axes of motion, and machine vision for part recognition and mark placement.

MARKING ON ALUMINUM IS COMPANY’S SPECIALTY

Aluminum is used in a large sector of activity, particularly in aeronautics and shipbuilding, the electrical and electronics industry, and is particularly appreciated in the automotive industry. Many auto manufacturers and equipment suppliers use aluminum for the manufacture of car chassis, steering columns and power steering components. It is also found in the manufacture of turbo bodies, engine crankcases, cooler or automatic air conditioning elements. Aluminum is also important in the expanding new energy vehicle category, particularly in the manufacture of battery casings and other electronic components.

Just as the use of aluminum varies, so do traceability requirements such as barcode, data matrix, alphanumeric or logo marking. In addition, there are several constraints linked to the nature of the aluminum (anodized, alloy, etc.) as well as a customer’s requirements, particularly in terms of marking contrast or depth. Some want the marking to be visible after the applications of coatings or of resisting surface treatments, such as shot peening.

SIC Marking USA’s (Pittsburgh, PA) laser product range is particularly suitable for marking aluminum components both in series and individually. The line consists of lasers that can be integrated with various options, including:

  • 3D function for marking on complex shaped parts
  • Vision function for fast and reliable barcodes and data matrix reading
  • Rotary axis for cylindrical parts marking

The range is completed by three stations (L-BOX, XL-BOX and XXL-BOX) allowing for a dedicated marking station. This can be integrated into a production line or used as a stand-alone marking station. Small, medium and even large production runs are possible. The resizing of the boxes, the creation of specific tooling, the addition of additional movements (Z axis, rotary axis) are options available on request.

SIC Marking is a world leader in industrial traceability and for more than 30 years has provided marking solutions to meet industry challenges associated with identifying aluminum components. For example, the company recently worked with a major German equipment manufacturer to meet its requirements, which were to mark a 7-by-7 mm DMC code on air conditioning compressor pistons to facilitate their internal traceability. These codes needed to be marked deep enough to allow proofreading even after shot peening and tinning. All this in reduced cycle times. After various marking tests carried out by SIC’s team, the chosen solution was a 50W fiber laser, its power enabling it to carry out deep marking in record time.

NEW PORTABLE QUICK-CHANGE FIXTURES AND BENCH TOP QUICK CHANGE BASE PLATES MAKE VERSATILE PIN MAKERS

Marking information on incoming raw material and outgoing finished parts requires human read characters, scannable 2D data matrix or in some cases both. With target mark areas in many cases very limited, MarkinBOX and Patmark pin markers can pin mark legible characters as small as 1 mm high, and 2D data matrix marking as small as 4 mm square has been done on 304ss.

The portability of the pin marker can be of great benefit particularly in material receiving areas and when it is more practical for marking of parts in place rather than processing under a bench top stand. MB Metal Technologies (Milwaukee, WI) accepted the challenge of making the MarkinBOX and Patmark portable pin marking products very versatile for customers. Is it a portable or is it a bench top? It can be both.

Quick-change fixtures with adjustable jaws that locate the MarkinBOX and Patmark portable markers on round, square, rectangular material for face marking can also be used with adjustable discs for end of bar marking. That is where the story began, addressing customer needs. It did not stop there, as customers based on quantities involved also indicated there would be instances that mounting the MarkinBOX or Patmark portables to a bench top stand would be optimum, allowing machine operators to also do the part marking after CNC machines completed their cycle. Productivity in both making and marking finished parts.

MarkinBOX and Patmark portable pin markers using standard quick-change fixtures will register the marker to the raw material or the part for accurate marking. In cases where the use of a bench top stand with the pin marker makes sense, the new bench top quick change base plate allows the portable MarkinBOX and Patmark units to be quickly attached to the bench top using a spring-loaded detent, which firmly attaches the marker.

Easy on and easy off a bench top stand makes MarkinBOX or Patmark portable pin markers a very versatile tool.

NEW INKJET MARKING SYSTEM FOR IMPROVED PART ACCURACY, QUALITY AND SAFETY

ESAB Welding & Cutting Products (Annapolis Junction, MD) offers an inkjet plate marking tool, an option for any ESAB cutting automation system. With options that include fixed or rotating heads, as well as drop-on-demand (DOD) or continuous inkjet (CIJ) technology, the inkjet station is ideal for steel service centers, shipyards and manufacturers that require traceability of their parts within the production environment. Inkjet marking especially appeals to manufacturers who want to identify parts during assembly but then want to shot blast or paint over the marks on the finished product.

“Adding an inkjet marking station to an automated cutting table reduces cycle time because the system can mark parts much faster, with less error and in much greater detail than a human operator working by hand,” said Steve Zlotnicki, ESAB Cutting Systems’ Global Product Manager. “Automated marking also eliminates the potential hazard of operators climbing on the table or trying to mark parts while the system is cutting.”

ESAB offers two types of inkjet technology. DOD prints characters up to 67 mm tall for greater visibility. CIJ uses dual-nozzle technology for the higher definition required by bar codes, QR codes or data matrix codes. CIJ can print characters up to 20 mm tall. Both types of systems can be used for marking either text or layout lines, and text can be oriented in any direction using an automatic rotation system.
