24.05.2012 | 22nd 5th 2012 at 16.00., Was inaugurated in The Pavilion - 19th Congress Hall edition of the International Engineering Fair in Nitra, which includes exhibitions EUROWELDING, CAST-EX, CHEMPLAST, EMA and STAVMECH - LOGITECH.
24.05.2012 | Observations from Shanghai - Chinaplas 2012
23.05.2012 | Plastic products must now meet higher requirements. In particular, standard plastics reach very quickly their temperature limits odolnosti.Cenovo effective alternative to expensive high-performance durable plastic is radiation cross-linking.
21.05.2012 | PLASTCOM® successfully passed the certification audit by TUV Nord and defended its management systems ISO 9001:2008 (Quality Management System) and ISO/TS 16949:2009 (Quality Management System with application in the automotive industry).
18.05.2012 | We will be glad you met on 17 May the Envirofilm in Kosice and 19 May in the Water Museum in Bratislava
17.05.2012 | Slovak plastics cluster (SPK) invites you to the first seminar of the series "Trends in the plastics industry", which will be held on 13 June 2012 at Brezina in Trencin. Seminar mediates interesting technical issues that professionals in the plastics industry will certainly use in practice.
HEF-DURFERRIT s.r.o.
With research and development center has developed a range of technologies, processes, coatings and coating, are able to provide solutions to most problems related to friction, corrosion, abrasion, in automotive, aerospace and construction material during the transformation / pressing, extrusion. ... / CERTESS under the brand name is now most common coatings based on TiN, TiCN, TiAlN, TiAlCN, CrN, but also not as advanced coatings based TiBN, CrXnY (with the possibility of any adjustment ratio X: Y) and DLC (possibly adjustment of any ratio of carbon in the form of graphite in the form of diamond).

Mechanisms and problems of pressing: When injecting plastics are facing many problems: - Zadieranie corrosion and friction of moving parts of some forms / ejectors, moving pins, tractor parts, guide rails, etc. ... - Fatigue, abrasive attrition / eg. through fiberglass /, corrosion / eg. through decomposition or condensation of chloride polymers, the effect of diesel / combined heat and pressure acting on gas in closed areas / In addition to these aspects which reduce the life forms we will mention two more critical parameters: - Forms the feed rate in most cases be directly proportional to the coefficient of friction material / plastic / forms on the surface. This directly affects the duration of the pressing cycle and hence the cost of a cycle. - Very important and well known phenomenon is the interaction between the surfacethe temperature should not exceed 150-200 ° C, occurs when changes to the mechanical properties of forms. How effective is proving just PVD coatings CERTESS X CERTESS DLC, PEMS ® technology-applied at low temperatures. Some applications are already in practical use.
Summary: The above examples demonstrated the advantages CERTESS coating applied to the molds and tools for plastic injection, rubber and aluminum: - Form filling easier - Reduce the frequency and forms of treatment by - Reduction of machine downtime - Improving the quality of the surface forming member / cast
02.02.2010 | Thin coatings obtained by methods PVD (Physical Vapor Deposition) or PACVD (Plasma Assisted Chemical Vapor Deposition) Already have obtained the surface engineering svou pry a position and their practical applications are now in many oblastech Already...
