TECHNOLOGY PROCESS

Lost foam casting

1, special lost foam casting technology

EPC (EPC or LFC) is made of plastic foam into a completely different parts structure and size with the real mould, via dip-coating bonded refractory coating, drying, dry sand molding, vibration compaction, and then poured into the liquid metal to make shape heating gasification disappear, and be consistent with the shape shape of the metal parts of casting method. Epc is a nearly WuYuLiang, precise forming of new technology, it does not need to close box modulus, use dry sand molding without binder, reduce the pollution, is considered to be the most likely to realize green casting technology of the 21st century.

2, pressure lost foam casting technology

Pressure is epc epc technology combined with pressure solidification technology of casting technology, it is in the pressure filling with sand box, pouring liquid metal to make foam gasification disappeared, rapid filling and sealing pressure, and access to a certain pressure of gas, make the liquid metal solidification under pressure molding casting method. The casting technology can significantly reduce the casting is the feature of the casting defects such as shrinkage cavity, shrinkage, porosity, improve casting density, improve the mechanical properties of castings.

3, the vacuum low-pressure epc technology

The vacuum low-pressure epc technology is the method of negative pressure lost foam casting and low pressure anti gravity casting method of composite and the development of a new casting technology. The vacuum low-pressure epc technology features are: a combination of low pressure casting and vacuum of epc technology advantages, under the pressure of controllable complete filling process, greatly improving the alloy casting filling ability; Compared with die casting, small equipment investment, low cost of castings, casting, heat treatment reinforcement; Compared with sand casting, casting with high precision, small surface roughness, high productivity, good performance; Against gravity and sprue become shorten channel and pouring temperature losses small, under the pressure of liquid alloy under control for feeding solidification, alloy casting gating system is simple and effective, high yield and compact structure; The vacuum low-pressure epc low pouring temperature, suitable for a variety of non-ferrous metal.

4, vibration of epc technology

Vibration of epc technology is applied in the epc process a certain frequency and amplitude of vibration, the casting under the effect of vibration field of solidification, the lost foam casting solidification process of molten metal in the imposed vibration time, vibration make the liquid phase and solid phase produces relative motion, and make the dendrite broken, increasing liquid crystal core, make the casting solidification feeding improve organization and refinement, finally, the mechanical performance improvements. The technology used in lost foam casting ready-made tight vibration table, mechanical vibration produced by vibrating motor, the metal liquid in dynamic incentive or nuclear, achieve the goal of refining group, is a kind of simple operation, low cost, no environmental pollution.

5, semi-solid lost foam casting technology

Semi-solid lost foam casting technology is a lost foam casting technology with the combination of semi-solid casting technology, due to the characteristics of this technology is to control the liquid solid phase ratio, also known as change control of semi-solid forming. The technology can improve the casting density, reduce segregation, improve the dimensional accuracy and the performance of the casting.

6, mold shell mold casting technology

Mold shell mold casting technology is investment casting technology combined with epc new casting method. This method it is made of foaming mould and parts shape of foam plastic shape surface coated with several layers of refractory material, wait for after its hardened and dry, will be one of the bubble shape type combustion gasification disappear, made of a plastic shell, the roasting, then pouring, and high dimensional precision casting method of a new type of precision casting. It has lost foam casting of the characteristics of the large size, high precision, and incrustation in revestment precision casting accuracy, strength, etc. Compared with the general investment casting, characterized by foam plastic mold material cost is low, like glue combination is convenient, gasification disappear easily, overcome the investment casting mould material easy to soften and cause of the deformation of investment casting, can produce all kinds of complex alloy castings of larger size

7, dissolved mold casting of suspension technology

Dissolved mold casting of suspension technology is a lost foam casting process combined with suspension casting a new practical casting technology. The technology process after the liquid metal is poured into the mold, foam plastic shape gasification, inclusion in the riser model of suspending agent, suspending agent or be placed in a certain position, or suspending agent is made with EPS foam) and chemical reaction with the metal to improve casting (or parts) organizational performance as a whole.

Because of lost foam casting technology of low cost, high accuracy, flexible design, clean environmental protection, suitable for complicated casting etc, comply with the general trend of foundry technology development in the new century.
