    Thermal management project 6 дней(-я) left

    Simple thermal project. Two disks one made of copper it is water cooled and on top of that same diameter molybdenum disk is place. The molybdenum disk is exposed to high temperature plasma. The top surface of the molybdenum should be reading 950C and the bottom surface of the molybdenum is cooled by the copper disk. The copper is water cooled where the inlet temperature is 22C and outlet temperature is 25C. We need to simulate the thickness of molybdenum required to maintain the top surface temperature of 950C and also profile the variation of temperature center to edge of the molybdenum disk (top surface)

    Source tin container for supplement powder 23 часов(-а) left
    ПОДТВЕРЖДЕН

    We are looking for a suitable tin container for our collagen powder. The idea is to stand out from the competition, who primarily use plastic jars. Requirements for the tin jar: - Volume: min. 700ml - max. 1500ml - food grade certified and compliant with EU regulations - order quantity 2000 - cost per tin should not exceed $3 - customisable: full body print - or copper finish and labelling options. - suitable for transporting powder (ideally, screw top, otherwise a seal or foil liner provided by the manufacturer) - shipped to EU - an example of a tin design we liked, but unfortunately wasn't tight or large enough, is attached. Your task is to find a tin and its manufacturer who can fulfil the above-mentioned requirements. However, we are also open to other, unique ideas.
