Marking of castings

Description of castings

Characterization of castings by micro-punching equipment and their tracking during machining and back identification

Project objective

Labelling of products (castings), finding the location and parameters of the label in terms of the best readability and durability of the label
Establish technical, software and organizational means for effective tracking of product movements
Analyse and evaluate production quality (statistical evaluation of process capability, process capability index)

Technical solution

Each product is marked with a 2D code upon arrival at the warehouse. The marking is done on a single-purpose machine with two micro-strike marking units. The machine is equipped with a code reader to verify the quality of the marking and to record the codes in a database. The database and the main application are run on a main computer (server) which is connected to an industrial Ethernet switch (LAN). A warehouse computer and 14 2D code readers located in the production area are also connected to the switch. Also connected to the LAN are a three-coordinate gauge computer (Zeiss) and a terminal at the inspection workstation with a printer.

Marking machine

The marking machine has 2 marking positions, one for each type of product. Each position is equipped with an Ostling PN4/6 marking head. All machine functions are controlled by a touch screen control computer. To verify the marked codes, the machine is equipped with a reader. A simple specific protocol is used to transfer data to the database. The limited functions of the protocol prevent harmful external interference with the control computer.

Database software

The database is of MSSQL type. The database server works on the main computer. The main computer also runs an application that is responsible for storing all the data from the code reader, marking machine, coordinate measuring machine and inspection workstations. At the inspection workstation, the terminal is used to enter data for each individual product, to classify products on pallets, to add a scrap type code and to print reports. An application on the warehouse computer provides information on stock levels and manages the dispatch of individual pallets. At the additional request of the customer, further applications were created for the shift foreman and production manager. These applications allow to evaluate the number of products at individual workplaces, workplace utilization, work efficiency of individual workers and others.

Statistics

Process capability reports are produced from the data obtained from the coordinate measuring device. The logs are exported in .xls format and show the Gaussian distribution, histogram, deviations and capability indices.

We can demonstrate most of the technologies we offer live or make samples.

We have purchased a machine for laser marking of castings from LINTECH. We highly appreciate the quality and speed of technical support from LINTECH in dealing with new requirements from our customers.

Since 2017 we have purchased 3 laser marking stations from LINTECH. The machines have been designed to suit our type of production (piece production of steel components for mechanical seals), i.e. with an emphasis on variability and easy reconfiguration. The machines work as they should. The change in marking technology has also brought time savings in the process and comfort of work (after breaking through the initial resistance, the change was positively received by the operators).
