The vacuum pressure casting, as this name indicates, is casting method which the major processes including the melting, pouring, solidifying are performed inside the vacuum chamber. The vacuum is able to minimum the gas content of the product, and prevent further oxidation happening to the metal. This is a quite expansive technic, manufacturing the special alloy steel and oxidate-like titanium casting part can use this method to achieve a very high specification requirements. Vacuum Die Casting Process The vacuum die casting is further modified technic to the vacuum casting. It is vacuum assisted high pressure die casting method but the main process performs after a certain degree of vacuum building up. The degree of vacuum is about to be 50~80 kPa. In practice, there're 2 major kind of method for the vacuum die casting: 1. using a vacuum cover seal the mold. The cover take the whole mold closed, and pump out the air inside, then do the die casting works. 2. the vacuum is created by the help the mold parting surface. There is specific designed air vent groove in the mold which connected with the vacuum system. When the injection plunger close the pouring gate, the air pump works to create the vacuum to a certain degree, then the die casting works could be conducted. Vacuum Die Casting VS Traditional Casting Compared with traditional casting, the same thing is: both are made by pouring molten or semi-molten metal into the mold, and then the required part is obtained by cooling and solidifying the metal. Differences from traditional casting. 1. The die-casting process, after pouring, before the metal liquid enters the mold, it enters the pressure chamber and then is pressurized and injected into the mold. This makes the filling speed of die casting faster than ordinary gravity casting. 2. In the process of die casting, there will be the process of pressurization and pressure-holding, by applying pressure, which makes the denseness of the metal inside after solidification better than the traditional casting parts. Advantages of Vacuum Die Casting Vacuum molding is a physical molding method, which combines vacuum technology with sand casting, relying on plastic film to seal the cavity surface and the back of the sand mold, with the help of vacuum pump pumping to generate negative pressure, resulting in the pressure difference inside and outside the sand mold so that the mold sand is tightly formed, after placing the sand core, closing the mold, casting, waiting for the casting to solidify, lifting the negative pressure or stop pumping, the mold sand will then collapse and get the casting. According to the current field of application, it can be mainly divided into vacuum sealed mold making (V method) and solid vacuum casting (FV method). The advantages are: (1) Moderate vacuum, high die cavity tightness and high casting quality. (2) Vacuum casting with computer simulation of mold flow analysis, can predict the generation of casting defects, for the design of the mold making scheme, can significantly save time and improve production efficiency.

The stainless steel has much better physical properties then iron and normal steel, but it possesses worse casting properties. Because the stainless steel has higher melting temperature point, by the liquid form it has worse flowability and bigger shrinkage ratio, and more easier to be oxidized. To prevent the happening of defects such as crack, sand stick, under-pounding etc., a series of more complicated technics are applied in the casting, thus the success rate of casting stainless steel is able to greatly be improved. The Features of stainless steel precision casting Take higher metal temperature reach to 1520~1600℃. For the small and complicated structure part keep the pouring temperature to melting point +150℃; for the big and thick wall part keep the pouring temperature to melting point +100℃; Make bigger and simpler gating tunnel; Use dry or heated casting mold; Make sure the casting product wall thickness is as even as possible and over 8mm, optimize the part structure in sharp corner and edge; Improve air permeability and passing ability by using hollow mold core or oil- sand core, or add coke with it. The Notice of Stainless Steel Investment Casting: For the material used to create the mold shell, similar to the iron casting somehow, the stainless steel casting china also uses silica sol and water glass as the adhesive material.

PE Pipe Water Supply Pipes 90 110 125 140 HDPE Straight Pipe Hot Melt Black Pipe For Water Supply -------- Basic Info. PE pipes for water supply are the replacement products of traditional steel pipes and PVC drinking water pipes. The water supply pipe must bear a certain pressure, usually a PE resin with a large molecular weight and good mechanical properties, such as HDPE resin, should be used. LDPE resin has low tensile strength, differential pressure resistance, poor rigidity, poor dimensional stability during molding and difficult connection, and is not suitable as a material for water supply pressure pipes. However, due to its high hygienic index, LDPE, especially LLDPE resin, has become a common material for the production of drinking water pipes. LDPE and LLDPE resins have low melt viscosity, good fluidity, and easy processing, so their melt index can be selected in a wide range, usually MI is between 0.3-3g/10min. Product name HDPE water supply pipe/PE pipe/polyethylene pipe Nominal pressure 0.6mpa-1.6mpa (SDR26-SDR11) Product color Black with 4 eye-catching blue lines Product wall Related to model and pressure Product length 6-12 meters Nominal outer diameter dn90-630mm
