  • SF6 gas measuring devices – Synergy Power Systems

    The SF6 gas must always be pure since humidity and toxic or corrosive decomposition products in circuit breakers impair the insulating properties of the gas. The gas quality has to be monitored in accordance with the F-gas Regulation (EU) 517/2014. The IEC 60480 directive also stipulates the limit values for the re-use of SF6 gas.

  • Reducing Sand Casting Core Defects | EMI White Paper Series

    CORE ProcessTooling DesignCORE Machine and Ancillary SystemsRecord KeepingCleanliness and Overall MaintenanceSummaryThe castings and process that require cores will need to be thoroughly defined up front. For example, what kind of finish is the customer looking? Is this a high production job, a periodic runner, or a 1-up prototype casting job? Will venting of the gas from the cores adversely affect your cast product? Is shake out of the cores from the finished casting going to be restrictive in any manner? By defining the economical limits of your decision making matrices, this also will typically lead to you the core process that will satisfy your requirements. Shell cores can be solid, smooth with high definition. These can also be molds where a foundry casts right into them for an excellent casting finish with minimum cleaning room requirements. The solid shell cores, when proper cured can provide excellent finishes internally for smooth casting requirements. This process can be cured with either electrical heated platens or gas fired systems, and the uncured sand can be re-used after collecti...
