EPC (also known as solid casting) is combined with the size and shape similar to the foam casting model into a model cluster bonding, brush fire-resistant paint and after drying, buried in the dry quartz sand vibrating molding, casting under negative pressure , so that the model gasification, liquid metal model position occupied, the new casting method after the formation of casting solidification cooling.
Compared with the traditional casting technology, EPC has the following features:
1, good casting quality, low cost;
2, the material is not limited to, the size of the Safe;
3, size
4, high precision, smooth surface, reducing clean-up, saving machining;
5, greatly reducing internal defects, compact;
6, can achieve large-scale, high-volume production. Automated assembly line of Environmental Protection.
7, can greatly improve the working environment, reduce labor intensity and reduce energy consumption.
Lost foam casting, lost foam casting, lost foam technology introduction
1. Casting size and shape precision, repeatability, with precision casting characteristics;
2. Casting surface finish;
3. LFC canceled the sand and core making Industry, eradicated since the system core, resulting in lower core casting defects and waste;
4. Substandard tank, not modulo, which greatly simplifies the modeling process, eliminating the casting defects and waste due to the modulo, together caused me;
5. LFC uses no adhesives, no water, no additives, dry sand molding, casting defects and eradication of all kinds of waste due to the moisture, additives and adhesives caused;
6. LFC processing system greatly simplifies the sand, the sand can all be reused, eliminating waste sand and sand preparation and Industry Industry;
7. Shakeout is extremely easy and greatly reduce the workload off the sand and labor intensity;
8. Casting no flash burr, makes clean polished workload reduced by more than 50%;
9. You can set reasonable shape in an ideal position Riser, without typing, modulus and other constraints of traditional factors, reducing the internal defects of castings;
10. LFC vacuum casting, more conducive to the liquid metal filling and feeding improves tissue density casting;
11. A combination of casting, a box of pieces, greatly improving process yield and productivity castings;
12. Reduce the allowance, reducing machining costs;
13. LFC is easy to implement mechanization automatic production lines, production line flexibility, in a production line can achieve different alloys, different shapes, different sizes of casting production.
