MARSHALL IS A LIQUID FILTRATION COMPONENT MANUFACTURER
Core Tube and Coupler Machining
Marshall Manufacturing Company has been manufacturing machined core tubes to multinational reverse osmosis and liquid filtration companies since the early 1970’s. We provide core tube to our customers, who serve a variety of industry segments including: purified drinking water, desalinized water, dairy, beverages, pharmaceuticals and more. We also provide machined couplers, which include the assembly of O-rings. Over the years we have grown as our liquid filtration customer needs have risen from moderate to high volume production.
Marshall produces a wide range of customer specified core tube lengths and diameters. Customer requirements span from smaller tubes starting around 12.7 mm (.500″) to tube diameters as large as 101.6 mm (4.00″). Length dimensions also vary depending upon customer objectives. We supply tubes in the smaller diameters at lengths as short as 254 mm (10″). The larger diameter tubes reach lengths up to 1,524 mm (60″). Machining high quality extrusions to customer specifications has become a specialty at Marshall. Supplying burr-free cross-holes by utilizing our proprietary processes is well within our bailiwick.
To smooth out the ebb and flow of customer requirements, Marshall works with many core tube customers to supply products on a KanBan basis. We communicate with our customers regularly, to understand what the minimum and maximum quantities are for each part number, so the customer always has the stock they need. We also connect with customers to identify changing conditions in the market.
Marshall Manufacturing is equipped to provide core tubes in a wide range of materials, including PVC, CPVC, ABS, Polysulfone and Noryl to name a few. Closely managed documentation control allows for consistent reliability with every order, making Marshall a premier manufacturer.
