The squeeze die casting, also names extrusion casting or liquid die forging, is kind of newly developed metal forming technic which combines the casting process and die forging like method. The basic principle is to fill the liquid metal into the pre-lubricated mold cavity, then gives sustained pressure to the metal, thus forming the solidifying hard-shell. The metal crystallization and solidification process is conducted under the pressure, so the defects such as shrinkage and porosity are greatly diminished. An almost defects-all-free product could be achieved by this technic. The Classification of Squeeze Die Casting There are 2 subdivisions of the squeeze casting aluminum: the direct squeeze casting and indirect squeeze casting. The formal technic is to give the pressure directly on the surface of liquid metal, while the last technic is to pressure the liquid maintaining in the gating part of the casting mold. Usually the direct squeeze casting has better resulted product than the indirect squeeze casting. Advantages of Squeezing Die Casting Extrusion casting is a process method to obtain castings (or ingots) by applying high mechanical pressure to liquid (or semi-solid) metals and metal matrix composites that enter the casting mold at a low speed so that they can be formed and solidified under pressure. Extrusion casting is the product of the combination of casting and forging, is a process between casting and forging, extrusion casting is close to forging in terms of performance. This extrusion casting process method can cast more complex pieces than forged parts. Due to the pressure molding, compared with other casting methods, the density is higher. Compared with forging, the price is relatively low because the mold is formed once. Due to the solidification under pressure, there are fewer internal defects, close to the forging organization, so the extrusion casting parts can be heat treated. Application of Squeezing Die Casting in Automobile Parts At present, die-casting is a more mature process method, die-casting is cheaper, first of all, a large number of applications in the engine pressure casting, compared with sand casting has the advantages of fast and high precision. In terms of strength can meet the requirements. However, the surrounding bearing parts have a tendency to use pressurized casting. Extrusion casting: vertical filling. High-pressure aluminum alloy liquid enters the mold cavity from the bottom upwards, the gate area is larger the speed is slower, and the gas can be exhausted from the exhaust tank. Extrusion casting is suitable for making wall thickness parts. Most of the automotive parts can be made by extrusion casting, but it is not advantageous for thin-walled parts. With the increasing call for lighter cars and lighter cars requiring more and more, extrusion casting is a technology with greater prospects.

Sodium silicate is a generic name for chemical compounds with the formula Na2SiO3. This material is generally colorless transparent solids, or in white powder, non toxic and non-inflammable. It is suluble in water in various amount. A more common name for sodium silicate is water glass, which is used in the iron or steel sand casting. The water glass works as a binder of the sand. It allows the rapid production a strong sodium silicate sand casting mold, by CO2 through the mixture of sand and sodium silicate in the mold, which hardens it almost instantly. Basic Property of Sodium Silicate Casting Product dimension tolerance ±0.5mm, CT7~8. surface finish Ra3.2. wall thickness up to 7mm. unit weight extent 1~20000kg. unit size limitation 0.03~3.5 meter. degree of complexity- complex. machining required- normal production lead time- short. production cost- low. Notice of Sodium Silicate Sand Casting Though in most conditions, sodium silicate sand casting is considered to be investment casting, but actually it also could be applied in the sand casting. Besides, sodium silicate sand casting is more suitable to make the large and complex structures and with even better surface finish and less defects. Principle of Sodium Silicate Casting The principle of sodium silicate casting industry and the detailed steps: melt the glass and mold it through the mold. Generally realize that after the mold is made, the glass melt is injected into the mold or realize that the pre-made mold is stacked with glass scrap in the mold, and put into the furnace together with the mold for melting, and anneal the mold with the glass domain anastomosis after molding.

The silica sol also shares the name of water glass in general, it is used by the meatal casting process as mold adhesive which is mixed with sand and several other materials. The silica sol is applied to both sand casting and investment casting technics. It is one of the most common investment casting processes. As the molding material, silica sol is able to stand temperature up to 1800℃. Similar to other investment casting processes, the silica sol investment casting process mainly consisted of wax injection, assembly, shell preparation, dewax, pouring, cut-off, and finished casting, etc. Compared to the resin investment casting, the silica sol method dewaxes into the high-temperature water, and the ceramic mold is made of water glass quartz sand. The surface quality is not as good as the resin casting, but it's cheaper and a bigger-sized part could be manufactured than silica sol casting. Application of Silica Sol Casting Mainly the silica sol is applying to the precision casting, because of its relatively high production cost but gives out a very fine accurate dimension, nice surface finish, and very good quality result overall. One of the other advantages for silica sol is that the internal defects such as porosity, holes, shrinkage are better controlled compared to another way of casting. So when you looking for a method to produce a small part but with high accuracy, surface demand, high corrosion resistance and you don't want to waste time waiting for the casting quality in slow improved gradually, silica sol investment casting is surely on your options list. The Basic Property of the Product Made by Silica Sol Casting: dimension tolerance ±0.1mm, CT4~6； surface finish Ra6.3; wall thickness up to 1mm; unit weight extent 0.1~100kg; unit size limitation 0.01~0.5 meter; degree of complexity- very complex; machining required- less or none due to its accurate dimension; production lead time- long; production cost- high; Influence Factor in Silica Sol Investment Casting The whole casting process has more than 40 procedures, the process is complex, and there are many process factors that affect the casting quality. There are many kinds of raw and auxiliary materials, such as silica sol, wax, zircon sand, molybdenum powder, defoamer, wetting agent, steel, rare metal, etc. According to the different mesh, there are more than 10 kinds of sols, including precision casting surface silica sol, precision casting backside silica sol, ordinary silica sol, enhanced silica sol, fast-drying silica sol, and zirconia powder. It is not suitable to control its quality, which affects the casting quality in different degrees. The production cycle is long and there are many uncontrollable factors. In the whole process, only the shell-making process takes 3-5 days. It takes 6-8 hours to dry the surface shell of silica sol, 4-6 layers to dry the back shell of silica sol, and 8-12 hours to dry the shell without silica sol. There are too many uncontrollable factors and defects will be formed with slight deviations in the process operation.

The name grey iron is because of the gray color of the fracture it forms, which is due to the presence of graphite. Grey iron die casting is the most common and widely used casting material. Grey iron is so popular in engineering applications because of its relatively low cost and the properties it presented. The grey iron has good galling and wears resistance because the graphite flakes self lubricates, and it also gives the gray iron part an excellent damping capacity because it absorbs the energy and converts it into heat. Grey iron is very suitable for casting works. But during the casting process, a less solidification shrinkage than other casting iron shall be considered. The silicon promotes good corrosion resistance and increased fluidity when casting. Below is a reference chart of other ASTM standards affecting grey iron. ASTM A395 & ASME SA395: ferritic ductile iron pressure-retaining castings for use at elevated temperatures ASTM A439: austenitic ductile iron castings ASTM A476 & ASME SA476: ductile iron castings for paper mill dryer rolls ASTM A536 & SAE J434: ductile iron castings ASTM A571 & ASME SA571: austenitic ductile iron castings for pressure- containing parts suitable for low-temperature service ASTM A874: ferritic ductile iron castings suitable for low-temperature service ASTM A897: austempered ductile iron castings Ductile iron Description of Gray Cast Iron Gray cast iron is a type of cast iron. Carbon is present in cast iron in the form of flake graphite. The fracture is gray in color. It has good casting and cutting properties and good wear resistance. Gray cast iron is used in the manufacture of frames, boxes, etc. The graphite of gray cast iron is in the form of flake. The effective bearing area is relatively small, and the graphite tip is easy to produce stress concentration, so the strength, plasticity, and toughness of gray cast iron are lower than other cast iron. However, it has excellent vibration damping, low notch sensitivity, and high wear resistance. Introduction to Cast Iron Molding Cast iron moldings are broadly defined as objects cast in iron, which is the most commonly used metal. Numerical simulation of the solidification process of thick and large section ductile iron castings with the application of computer was carried out for the temperature field. Increasing the strength of the mold shell, baking temperature and decreasing the pouring temperature are beneficial to reduce the scrap rate of castings and improve the quality of ductile iron castings. Factors Affecting the Performance of Gray Cast Iron The influence of chemical composition In production, the quality fraction of carbon and silicon is mainly controlled. If the mass fraction of carbon and silicon is too low, the cast iron is easy to appear white mouth organization, and the mechanical properties and casting performance are very low; if the mass fraction of carbon and silicon is too high, the graphite flakes are too much and coarse, and even the graphite floats on the surface of the iron, which reduces the performance and quality of the castings. Therefore, the carbon and silicon content of gray cast iron is generally controlled at 2% to 4% C; 1.0% to 2.0% Si; 0.5% to 1.4% Mn. The effect of cooling rate Under certain casting process conditions, the cooling rate of the casting has a great impact on the degree of graphitization. Castings of different wall thickness with the increase in wall thickness, the cooling rate slows down, and carbon atoms have sufficient diffusion time. It is conducive to the full graphitization process, room temperature organization is easy to form gray iron organization; but thin-walled parts in the cooling process, the cooling rate is too fast, easy to form a white mouth iron organization.
