 Press Releases

  • “Sealink Corp aim to be No.1 in global market with No-Lubricant Mechanical Seal.” 

    Sealink is being spotlighted by developing mechanical seals which don't need lubricants and lubricant supply systems. Sealink have superior competitiveness on technologies and qualities. Sealink's mechanical seals are the first development in the world.

    Mechanical seals applied on petrochemical agitators have high repurchase rate because of reducing the risk of explosion and the cost. Sealink is concentrated on developing 'IoT real-time leakage sensor security monitoring systems'. Sealink is a Korean hidden champion supplying to Samsung and Intel competing with America, Japan and Germany by technology.

BEWARE - Special Warning Notice about ExpoGuide and FAIRGuide

With the ongoing solicitations, SEMI would like to continue to alert you with questionable professional practices perpetrated against exhibitors by (Austria) and Expo Guide (Mexico), Event Fair - The Exhibitors' Guide with their misleading directory services. There may be others that we are not aware of and are hence not named here. 

These companies provide legitimate exhibition guides aimed at exhibitors across the globe offering online listing services. They use a form which resembles and organizer's free catalogue listing service, inviting exhibitors to complete the form for an entry in an on-line directory. Unsuspecting exhibitors who sign and return the form are then contracted into a three-year, non-retractable agreement, which could cost the exhibitor a significant amount of money, with very limited foreseeable benefits. The details are often available on the form itself, but are often too small and insignificant to be noticed. It is always wise to really the small print before signing a contract, and if the information is impossible to read then the contract should not be signed. These publications have no connection with SEMI or any of our events, and it is important that all companies are made aware of this. 

Should you receive any communication from the Expo-Guide and or related company, please IGNORE THEM COMPLETELY and DO NOT COMMUNICATE WITH THEM IN ANY WAY.
