Lost foam casting technology and products to the appearance of good quality and dimensional accuracy is higher, as well as good workers labor intensity is low and the working environment in the casting industry in China is very good use, especially in recent years, the relevant domestic manufacturers and technical personnel in raw materials and process equipment research and development, make the process a basic implementation localization, further promoted the lost foam casting process, the development of the technology.

However, epc still exist some problems in the development

1. The lost foam casting manufacturer, normal and stable production.

2. Lost of foundry production scale is small.

3. Some manufacturers of epc casting quality, casting yield is low, failed to show the process of advancement, seriously affect the market competition ability of this new technology.

4. The lower mold foundry production of products in China, for complex castings we can't a large number of stable production.

5. Some key equipment imported, domestic form a complete set of lost foam casting, investment is large, dependence on foreign raw and auxiliary materials, localization process is slow, can make a good sample, but the scale of production at costs come down, lose its competitive ability.

6. Quite a number of small factory, lost foam casting equipment is too simple, workshop dust float in the sky, than the traditional sand casting work condition is poor, dust and harmful gases, such as serious environmental pollution, loss of reputation as a "green casting".

The reason:

L. introduced some manufacturer of epc casting process is not careful, not enough science, lack of professionals on the deep understanding of the epc, goals, products are not clear or lack of fully demonstrates the technical feasibility and economic rationality; The lack of a complete feasibility analysis report, is in a hurry.

2. Corporate leadership expectations of new technology on high, enterprise internal and without sufficient technical personnel to digest the process, practice less, not stable production.

3. Most of the manufacturers of epc process is very rough, epc looks be like simple, actually to control process is greatly increased, we basically still in the early anti-wear a simple approach for more complex casting, mould, casting system and so on rough, no strict process discipline.

4. Lack of strict quality assurance system, the lack of strict process management.

5. Our technology accumulation is very few, is not stable.

6. Raw material quality is poorer, less stable.

7. The transfer unit level is not high, in favor of the impact to production unit.

8. The cause of the market, some units, shut down due to fierce market changes, new product development ability to restrict the speed of production.

9. The cause of the financial resources.

Countermeasures:

1. Must be according to the product prior to the start of the market, production conditions, personnel and financial conditions for feasibility analysis. And a national survey, choose reliable technology based on unit or partners. Then main products advanced technology experiment was carried out and the overall design workshop, determine the outsourcing equipment detail and homemade equipment detail. Organizational construction, equipment installation commissioning and personnel training, the final trial production, inspection and acceptance, don't be impatient for success, and should be in an orderly way.

2. The factory has already begun, for technology ability is stronger, complete production conditions, should be the main focus on market development and technology on the increase, improve yield and reduce the product cost, the conditional should also improve the product level, to enter the international market.

3. Disappear for some die casting factory product quality is low, enterprise benefit is bad, should be comprehensive reorganization, rapidly changing face, accelerate the investment returns.

4. Strengthen exchanges (conference materials, magazines, Internet, etc.) across the country to cultivate a group of direct production of lost foam casting expert, training (training, internships, etc.) a large number of epc key workers.

5. Improve the level of specialization, with different castings in the country to establish model of several large-scale production workshop.

6. Improve socialization, the establishment of regional center factories, such as establishing public mould factory, and give full play to the potential equipment.

7. Improve the supporting factory scale, quality, to establish a stable raw material, equipment supply base.

8. To improve technical support unit (universities, institutes, technology development company, etc.) of the quality, level and scale.
