Can you imagine a modern vehicle without an identification number on it? Or a car part without a serial code? Car marking has become for the automotive manufacturers not only the necessity but, in time, an obligation. Inscribing on car parts is today one of the fields where strict requirements are set by both informal industry standards and official regulatory bodies.
In automotive manufacturing marking provisions many objectives at once: traceability for safety issues, especially in case of defective parts on the line, warranty issues, ownership claims, stolen cars recovery, etc. And that sets high demands to the quality of imprints. The most important ones, according to the car marking experts at HeatSign, an experienced marking solutions provider for automotive industry, are listed below.
Vehicles and vehicle parts are the products being used for years and even decades, so the inscription on them must live for at least as long as that.
- Easy readable
Car identification codes do not normally include any specific graphics or symbols, the VIN numbers are required to consist of only numbers and Latin letters (except I and O that can be confused with 0 or 1). But that means every symbol has to be clearly readable and catchy for human eye and machine scanning.
- Direct part marking only
To prevent forgery and the loss of information, car parts are engraved directly on part surface. Labels and plates or other indirect inscribing methods are very rare.
- Large and heavy metal parts
Direct part marking is equally applicable to large vehicle parts like chassis, motor blocks, body panels and frames. However, those are not to be engraved by traditional static solutions and need special treatment.
What solutions can satisfy the listed requirements?
Car Marking System: Dot Peen
Dot peen technology has become traditional in automotive industry. It easily processes different metal types and alloys, providing deep and highly legible inscriptions. The gentle contact with the metal surface ensures accurate and clear signs that are resistible to any exposure. In fact, dot peen produces the most permanent inscriptions promising to outlive even the part itself. No wonder car manufacturers stick to this technology.
Portable and Handheld Solutions for Marking Car Parts
Portable machines are lightweight and offer flexibility and mobility. In automotive, they are mostly valued for their wide options for handling large and heavy parts. Handheld machines are the most flexible and help to access difficult zones, whereas portable machines are often equipped with electromagnetic basement for increased stability. Portable machines can be computer-operated or CNC-operated with in-built software and touch screen.
Every car manufacturer is striving to stand out in the modern high competitive market, and this results in different demands manufacturers have to car inscribing. Unconventional marking needs can be accommodated by machine customization. For example, the marking head or stylus can be customized.
So how can a vehicle manufacturer achieve the best marking results? 1. Choose dot peen technology for accurate and permanent imprints. 2. Use handheld or portable machines to handle large and heavy metal parts. 3. Customize for best-suiting marking solutions. This will ensure your durable and precise VIN numbers and codes that comply with the industry standards.
