gating system The pouring system is composed of a gate cup, a straight gate, a horizontal gate, and an inner gate. It is a channel opened inside the mold to introduce liquid metal into the mold cavity. The function of the pouring system is to control the speed of metal liquid filling the mold and the time required to fill the mold; Ensure that the metal liquid enters the mold smoothly, avoiding turbulence and erosion of the mold; Prevent slag and other inclusions from entering the mold cavity; During pouring, do not involve gas and try to ensure that the casting cools down in accordance with the principle of sequential solidification. The pouring system includes: 1. Pouring cup. The metal liquid poured into the ladle, also known as the external gate 2. Straight gate. Connect the outer gate and the transverse gate to introduce molten metal from the outside of the mold into the inside of the mold 3. Horizontal gate. Connect the straight gate and distribute the metal flow from the straight gate. 4. Inner gate. Connect the transverse gate and inject molten metal into the mold cavity. The function of the pouring cup is to guide the liquid metal poured from the ladle into the straight gate. The gate cup of small castings is mostly funnel-shaped, and the diameter of the upper gate should be more than twice that of the straight gate, and it is generally made directly on the mold during molding.

Everflon is a registered trademark of the C&F Group for its fluoropolymer resins.Everflon PTFE fluoropolymer resins are part of the C&F family of fluorine-based products that also includes Everflon FEPEverflon ETFE and verflontm PFA fluoropolymer resins and Everflontm PVDF fluoropolymers.These materials can be used to make a variety of articles having a combination of mechanical, electrical, chemical, temperature, and friction-resisting properties unmatched by articles made of any other material. Commercial use of these and other valuable properties combined in one material has established Everflontn resins as outstanding engineering materials for use in many industrial and military applications Everflon resins may also be compounded with fillers or reinforcing agents to modify their performance in use. The design and engineering data presented in this handbook are intended to assist the design engineer in determining where and how Everflontn resins may best beused. lt is recommended that the design engineer work closely with an experienced fabrica tor because the method of fabrication may markedly affect not only production costs, but also the properties of the finished article.
Everflon FEP Aqueous Dispersion Everflon FEP D50 is an off-white aqueous fluorinated ethylene propylene (FEP) dispersion stabilized with a non-ionic surfactant. It is a general-purpose dispersion that can be used to impart some the unique properties of FEP to end products that would be difficult to make using traditional melt extrusion processes. It can be used to coat or impregnate porous structures, or to make thin films. It can be coated and melt bonded to polytetrafluoroethylene (PTFE) resin or used as a hot melt adhesive. The FEP resin in Everflon FEP D50 is a melt flowable thermoplastic, providing superior properties typical of fluoroplastic resins: retention of properties after service at 204 °C (400 °F) and useful properties at -240 °C (-400 °F). Everflon FEP D50 aqueous dispersion provides: Inertness to nearly all industrial chemicals and solvents Stability at high temperatures Excellent dielectric properties Excellent weatherability Application Heat-sealable top coatings for PTFE-coated fabrics for belting, circuit boards, architectural fabrics, and electrical insulation Cast film for capacitor dielectrics or chemical barriers Hot melt adhesive for PTFE, PFA, and FEP parts Metal coatings

A FEP resin coating on woven fabrics made of fiberglass, fiber, or other high-temperature resistant fibers, can be made by dip coating. Successive passes may be necessary to build the desired thickness to produce a smooth, crack-free coating. Each coating layer is usually dried to remove water (typically at 120 °C [250°F]), baked to remove the wetting agent (typically at 270 °C [518 °F]), and then heated above the crystalline melting point of the resin particles (approximately 265 °C [509 °F]). If the Everflon FEP D50 is being used as a top coat over a PTFE-coated fabric or other parts, the coating must be heated to melt the PTFE (approximately 337 °C [639 °F]) to maximize adhesion. Other solid or liquid ingredients can be added to Everflon FEP D50 to provide specific processing or finished product behavior
