Mold production is based on OUR company’s own quality standards. Through continuous improvement of technological processes, implemented by our qualified personnel of design engineers and technologists, the highest quality of molds and services related to their maintenance can be offered. Introduction of new technological solutions is always preceded by tests in our specialist testing plant, which makes it possible to control the quality and continuously improve the production process. We always try to recognize the needs of our customers and meet the growing market demands.
The quality of molds is affected not only by the technological process, but also by the quality of material used for production. Quality control starts as early as the steel delivery stage. The quality of steel delivered to our factory is examined by means of various methods and tests, e.g. ultrasonic examination of every steel sheet used for mold manufacture. Examination is made with the use of a dedicated cart with a transmitting/receiving head and a flaw detector installed. The material is checked for discontinuities such as delaminations, lappings, cracks, and chip weldings, the presence of gas bubbles and nonmetallic intrusions. During mold production process all welded joints are examined by means of ultrasonic method. The quality of joints is specified in the PN-EN 25817:1997 standard. Welded joints are examined for the occurrence of flaws such as cracks, chip weldings, pinholes, and gas bubbles. Ultrasonic examinations are also performed during repair and refurbishment jobs for molds and other devices. We cooperate exclusively with reliable steel suppliers who guarantee the premium quality material delivered.
ULTRASONIC EXAMINATION OF STEEL BY MEANS OF DEFECTOSCOPE
MOLD DIES ARE CUT BY THE MOST MODERN GAS BURNERS DELIVERED BY THE MESSER COMPANY, WHICH GUARANTEE PRECISION ALREADY AT THE STAGE OF BURNING THE MOLD LINER
Liner cavities and stamp plates are machined on high class, three- and five-axis CNC machining centers developed by machine tool manufacturers like FPT, Mori Seiki, and Hartford. These centers ensure a very precise machining process and, what is the most important for the quality of concrete products, high accuracy and repeatability of mold liner cavity dimensions. Liner cavity wall surface is treated to facilitate the demolding of vibrated concrete and ensure reliable mold operation. Tamper shoes are made with circumferential clearance of about 0.3 ÷ 0.4 mm for low molds and 0.5 ÷ 0.6 mm for the high ones. Such small circumferential clearance of the cavity guarantees top quality of concrete product and extends mold lifetime.
