High efficiency durable casting EPC production line

Product Description

Production principle:

EPC production line.

The first made of foam plastic model according to the requirement of process, coated with a special high temperature resistant coating,after drying, placed in a special sand box, and then according to the requirement of process filled with dry sand, using 3D vibration compaction, vacuum pumpingcasting metal liquid, this model for gasification disappears, the liquid metalreplacement model

replicate the same, and foam plastic model of casting.

Technological process

A. The production of plastic foam epc;

B. Combination of gating system;

C. Gasification die surface spray brush special refractory coating and drying;

D. The special layer sand box is arranged on the three-dimensional vibrationbench;

E. Fill in the bottom sand (dry quartz sand vibration compaction, scraping);

F. The gasification model drying is placed in the bottom sand, according to the requirement of process filled with dry sand vibration, numerical controlappropriate time, then scraping the box mouth;

G. Covered with plastic film opening box, placed on the pouring cup, starting the vacuum system, the dry sand fastening after molding, pouring, gasification modeldisappeared, replaced the position of liquid metal.H, release vacuum, at the same time casting condensation rear box, the casting is taken out from the loosein quartz sand.

Product advantages

The disappearance of sand casting casting compared with traditional has the following advantages:

1. Lost foam casting does not require typing and the lower core, so it is especially suitable for the complex geometry, the traditional casting difficult to complete thebox, shell castings, castings of bobbin.

2. EPC casting with dry sand buried model, can be used repeatedly, industrial waste less, the cost is obviously reduced.

3. Lost foam casting no burr, clean working hours can be reduced more than 80%.

4. Disappear can joint use casting, not only can make the cast iron, ductile iron,can also be cast steel, so Xiang Linghuo, wide scope of application.

5. The EPC is not only suitable for casting large batch, mechanize operation, also suitable for small batch product manual mosaic model.

6. The EPC if investment in place, can achieve the air clean, no sand ground, low labor intensity, working environment is good, will be the male dominated industrybecomes to women dominated industry.

7. The EPC has cancelled the molding procedures, there is a certain culture level,after a short training can become skilled workers, so the strength, especially forthe regions and enterprises lack of technology.

8. Disappeared for group casting casting, dry sand buried sand removal easier,in some castings can also be carried out according to the use of residual heat treatment.

9. The EPC is not only suitable for medium and small, more applicable to do large castings, such as: the machine bed, large diameter pipe, big cold die parts, large mine equipment fittings, because the model of short production cycle, low cost,the production cycle is short, so it was particularly well received.
