Today at Sivart we want to introduce you to a new type of laser marking, different from those discussed so far. This is an option that opens new doors in the world of marking and we are sure that many of you will find it useful. Let’s get to it!
Traceability is increasingly necessary not only for safety applications, but also for a growing number of applications throughout the value chain and in a multitude of industries. Die castings are no exception. The structural/high integrity market is one of the fastest growing market segments. Not surprisingly, traceability and marking of die castings is becoming a hot topic. Increasingly, conventional die castings have identification requirements for 100 % of the individually produced parts.
Currently, there are several technologies (each with advantages and disadvantages) commercially available. In choosing the right technology for marking die castings, many requirements can come into play.
Requirements to be met by the technology used for marking:
Cycle time is key. Minimizing process complexity, capital and ongoing operational investments will ensure success.
What happens when marking on metal? When marking an identifier on metal, high energy is used through an infrared pulsed fiber laser and is absorbed by the surface. In this way, the minimum energy threshold of degradation of the material itself is achieved. This causes its surface, and therefore the way in which natural light is reflected, to be modified, creating a high contrast marking.
Although, since the marking time depends, among other things, on the laser power, the laser power is easily adaptable to meet the cycle times, ensuring minimum cost.
The laser technology we offer at Sivart meets all the criteria described above for the identification of the different die-castings, guaranteeing reliable and perfect traceability.
In addition, speeds can be adapted to then obtain the desired contrast, and adjustments can be made for surface temperatures and various alloys.
Today there are a large number of industries that require casting to achieve all their basic components. The following are some of the most important industries:
Today’s airplanes are equipped with powerful propulsion engines, which contain indispensable components, present in important parts of airplanes and helicopters made of steel alloy castings, aluminum, magnesium… produced with micro fusion technology.
The urban planning industry is another highlight. Our streets are full of components that have been die-cast. These are fundamental to urban safety and functionality. Manhole covers cover subway accesses, allow safe traffic, streetlights illuminate streets, squares and parks… The list of elements is endless.
Nowadays, stoves, boilers, bathtubs, etc. are indispensable in every home… Well, all these elements exist thanks to the foundry industry, which indirectly ensures our level of well-being.
In addition, many household appliances could not be manufactured without the use of castings (stoves, refrigerators, washing machines, etc.).
And although all the industries discussed so far are essential, the one below is, if not the most important, one of the most relevant. The electricity industry cannot ignore the use of castings, mainly made of steel or cast iron alloys. Regardless of the energy source (renewables, fossil fuels, …) systems cannot be built without die-cast components. Turbine impellers, motion transmission chain, water propulsion, …
Finally, the foundry is undoubtedly the protagonist in the casting industry. Automotive. Structural components such as the engine, chassis, transmission and braking system elements come from castings, as do numerous accessories (such as door handles).
In addition, all vehicle components have traceability codes. Each component is marked with an identification code, which contains valuable information for the manufacturer: batch, date and time of production, place and factory of origin, which is essential to ensure quality and to be able to intervene in a timely manner in case of breakdowns.
Having seen what the marking in casting process is and what applications it has, we take the opportunity to tell you that all industrial marking machines that we have in Sivart have installation services, commissioning and training for your company, in addition to having a fast and efficient after-sales service.
