Even you know nothing about Lost foam casting production line, we also can help you understand the whole process and equipment technical requirements from very beginning, provide one-stop service, help you to start LFC casting production line at the fastest speed and produce high quality products to maximize profits for you.
Product Description
Complete Lost foam casting system is used to produce various metal castings by lost foam process. The equipments line produces various castings such as motor body, cylinder head, complicated pipe fittings, shell, housing, engine block etc. The castings produced by our lost foam casting equipment are available in various industries, such as engineering machinery, textile machinery, building automobile production etc.
Lost-foam casting process (LFC) is a green and environmental casting method. The process is assembling the foam patterns which has same size and shape with casting into cluster, after coating and drying, embedded into the dry sand and compacted by vibration table, the pouring under negative pressure to decompose the pattern, after solidification - the casting is formed.
It is a type of evaporative-pattern casting process that is similar to investment casting except foam is used for the pattern instead of wax. This process takes advantage of the low boiling point of foam to simplify the investment casting process by removing the need to melt the wax out of the mold.

Product Advantages
1.Casting is with accurate size and shape, good repeatability and has the characteristics of precision casting.
2.The sand core and core production department were eliminated, and the casting defects and wastes caused by the core and the lower core were eliminated.
3.It greatly simplified the molding process and eliminated the casting defects and waste products caused by the model and the box.
4.Dry sand molding with no binder, no moisture and no additives is used to eliminate all kinds of casting defects and wastes caused by water, additives and binder.
5. The sand treatment system is greatly simplified and the sand can be reused in all cases.
6. Falling sand is extremely easy, which greatly reduces the workload and labor intensity of falling sand.
7. The casting has no flying edge burr, so that the cleaning and polishing work is reduced by more than 50%.
8. In the ideal position, the reasonable shape of the gate can be set, which is not restricted by the traditional factors such as typing and drawing, thus reducing the internal defects of the casting.
9. The negative pressure casting is more conducive to the filling and shrinkage of liquid metal, which improves the density of the casting.
10.Combined pouring, a case of many pieces, greatly improved the casting process production rate and production efficiency.
11. Reduced processing margin, reduced machining cost.
12. It is easy to realize mechanized automatic production line production, the production line is flexible, and the production of different alloy, different shapes and different sizes can be realized in one production line.
13.The metal mold can be used up to more than 100,000 times, reducing the maintenance cost of the mould.
14.Reducing dust, soot and noise pollution, greatly improving the working environment of foundry workers, reducing labor intensity, and the male-dominated industry can become the industry dominated by women workers.
15.The process operation is simplified and the technical proficiency of the workers is greatly reduced
16.The shape of the parts is not limited by the traditional casting process, which frees the mechanical designer to design the ideal casting shape freely according to the performance of the parts.
17.Simplify the design of the factory, can reduce 30 ∽ 40% of investment in fixed assets, covers an area of and a building area of 30 ∽ can reduce 50%, 10 ∽ power consumption can be reduced by 20%.
18.Die casting process is widely used, not only for cast steel and cast iron, but also for casting copper, casting aluminum and so on.
19.The die casting process is not only suitable for castings with simple geometrical shape, but also suitable for castings with multiple open edges, multi-core and geometric shapes.
20. It is helpful to improve the inner quality of castings by the process of die casting, which can realize the casting of microseismic state and promote the formation of metallographic structure with special requirements.
21.In dry sand, it is easy to get rid of sand and the temperature is synchronized. Therefore, heat treatment can be made by using waste heat. In particular, the water edge treatment of high manganese steel castings and the solid solution treatment of heat-resistant castings are very satisfactory, which can save a lot of energy and shorten the processing cycle.
22.With the process of die casting, the casting of any size can be completed according to the melting ability.
