TongFeng Services Welcome to TongFeng Our service, quality, quick smile from the beginning of everything 1.Cutting: TongFeng has several different saws to meet "cut to length" requirements. (1). High Volume Cutting (2). Close Tolerance Cutting (3). Large Diameter Cutting (4). Short Lengths (5). Long Lengths Deburring: The cutting process generally leaves "metal burrs" on the cut to length hose. TongFeng uses a wire brush deburring machine to remove burrs and sharp edges from cut lengths. Degreasing: TongFeng uses a water soluable animal fat lubricant during the manufacturing process. If needed, the tubing can degreased in our ultra-sonic degreasing chambers. 2.Electro Polishing: Electropolishing stainless steel creates a chrome like appearance. It is accomplished by submerging cut lengths into a chemical electrolyte bath in combination with a rectified electric current. The process removes a small layer of the surface and results in a bright shiny finish. 3.PVC & Other Coatings:TongFeng can also accommodate customers who need to have an extruded plastic covering applied to their tubing. Examples: Clear PVC, Black PVC, High temperature Thermoplastic Copolyester Elastomers, etc. 4.Braiding:Braid is a woven metal cover that can be produced over tubing. TongFeng can also manufacture metal braid over the stripwound metal hose.
