The main advantage of the epc
1. The shape of casting size precision, good repeatability, has the characteristics of precision casting;
2. The casting surface finish high;
3. Cancel the sand core and core xiaohong, eliminated due to core, the core of casting defects and waste;
4. Out of box, not modulus, greatly simplifying the molding process, to eliminate the casting defects caused by modulus, tanks and waste;
5. The binder, water, dry sand molding without any additives, eliminated due to moisture, additives and binder caused by all kinds of casting defects and waste;
6. Greatly simplifies the sand processing system, the sand can be repeated use, all cancelled &industry sand preparation and waste sand treating section;
7. Shakeout extremely easy, greatly reduces the shakeout workload and labor intensity;
8. Castings without flash burr, make clear the burnish workload by more than 50%;
9. Can be set up in an ideal position reasonable shape of the riser, is not subject to classification, the restriction of traditional factors such as modulus, reduce the internal defects of casting;
10. Negative pressure casting, is more advantageous to the liquid metal filling and feeding, improved the casting organization density;
11. A combination of pouring, a box, greatly improving the casting craft production rate and production efficiency;
12. Reduce the machining allowance, reduces the machining cost;
13. Automatic assembly line production, easy to realize mechanization production line elasticity, can implement different alloy on a production line, different shape, different size of casting production.
14. You can cancel the draft Angle;
15. The use of metal die life can reach more than 100000 times, reduce the mold maintenance;
16. Reduced the dust, smoke, and noise pollution, greatly improved the working environment of foundry workers, reduce the pain
Dynamic strength, mainly men can become predominantly female industry;
17. Simplified the process operation, on the degree of skilled workers required is greatly reduced;
18. The shape of the parts is not restricted by the traditional casting process, the liberation of the mechanical design workers, to make it according to the using performance of the parts, free to design the ideal shape casting;
19. Can reduce the casting weight;
Reducing the production cost; 20.
21. Simplified the factory design, can reduce 30 ∽ 40% of investment in fixed assets, covers an area of area and construction area
30 ∽ 50%, reduce power consumption can reduce 20%; 10 ∽
22. The epc technology widely used, not only suitable for cast steel, cast iron, more suitable for cast copper, cast aluminum, etc.;
23. The Epc Casting process is not only suitable for simple geometry, more suitable for ordinary casting to attack rolled edge, core, geometric shape of complex castings;
24. The Lost Foam Casting process can realize microtremor state pouring, promote the formation of the special requirements of metallographic organization, to improve the inner quality of casting;
25. Combined on the dry sand casting, easy to take off the sand, temperature, therefore can make use of waste heat to heat
Richard.Especially high manganese steel castings water edge processing and heat resistant steel solid solution treatment, the effect is very ideal, can save a lot of energy, shorten the processing cycle;
26. The use of epc process, can according to melting ability, complete any size castings.

Exit-entry management is an important aspect of national security management. With the formal implementation of the new "Administrative Measures on Quarantine of Imported and Exported Personnel on November 1," entry personnel are prohibited from carrying bird's nest, soil, and genetically modified organisms, etc. in the future.
<br> <br> prevent pests into new "approach" that, in order to prevent human infectious diseases and medical vector, animal diseases, parasitic diseases and dangerous plant diseases, insects, weeds and other pests into , To protect human health and agriculture, forestry, animal husbandry, fishery and environmental safety, and make changes to the original "Measures."
Compared with the old version, the new version expands the range of passenger prohibited goods. The newly added bird's nest (excluding canned bird's nest) is a prohibited entry. Plants and plant products originally banned from entry include fruits and eggplants, peppers, tomato fruits, etc. The new approach extends the scope to fresh fruits and vegetables, and for the first time include agricultural GMOs and endangered wildlife and their products in immigration Scope of quarantine.
Automatic transfer baggage check <br> <br> With the formal implementation of the new approach, there is demand for passenger transit will become more convenient. In the past, when transit passengers flew from a foreign country to an airport in the country, they had to take out the baggage, pass the inspection and quarantine, and then move to a domestic flight. In the future, the inspection and quarantine department will be unified with the "transfer of joint services," set up a transfer baggage inspection area, pending inspection and quarantine, the staff will be transferred directly to the domestic flight baggage, the entire process does not require passengers to move on their own luggage.
New regulations for pet isolation period <br><br><br><br><br><br><br><br><br><br> Pets for entry into the country will be "differentiated" for the first time from the infected area or non-epidemic area, instead of being isolated for 30 days at the designated place as before.
According to Zhang Zhaoping, deputy director of the Animal and Plant Inspection and Quarantine Bureau of the Beijing Entry-Exit Inspection and Quarantine Bureau, the live animals brought into the country are still limited to dogs or cats, and each person is allowed to bring one animal at a time. However, the new approach is based on rabies epidemic and non-epidemic areas for the first time. Among them, pets from rabies-producing countries or regions must also be quarantined and quarantined for 30 days at designated isolation sites; pets from non-rabies-producing countries or regions can be transferred to other sites for isolation after being isolated for 7 days at designated isolation sites.
Entry passengers are prohibited to bring bird's nest
