Product Name: Best Quality Equipment for Lost Foam Line Model NO.: 1 Certification: CE, ISO 9001:2008 Standard: GOST Surface Roughness: Ra0.05 Casting Method: Vacuum Aspirated Casting Type: Clay Dry Sand Warranty: One Year Cleaning Process: Steel Shot, Steel Grit Low Voltage Apparatus: Siemens, Omron, Schneider Trademark: DEXU Transport Package: Stretched Film Specification: metal Origin: China HS Code: 845430 Product Description A. Product DescriptionEpc (also called real mold casting) is a foam mould with unbond agent dry sand combined with real mold casting, vacuum technology is similar to the casting size shape of foam model binding into clusters, brush after refractory coating and drying, buried in the dry quartz sand vibration model, under the negative pressure casting, make the model of gasification, liquid metal model position, after cooling solidification form a new type of foundry casting method.B. Featuresa. Good casting quality and low cost.b. The material is not limited, the size is appropriate.c. High precision, smooth surface, reduce cleaning, save machine.d. Internal defects are greatly reduced and casting structure is compact.e. Can achieve large-scale, mass production.f. Suitable for mass production and casting of the same castings.g. Suitable for manual operation and automatic production line operation control.h. The production status of the production line meets the requirements of environmental protection technical parameters.i. It can greatly improve the working environment and production conditions of casting production line, reduce labor intensity and reduce energy consumption.C. Process Flow1. Make blister gasification molds (manual and mechanical);2. Blister gasification, drying after mold combination;3. The surface of the foam gasification mold is brushed and sprayed with fire-resistant coating and then dried again (it must be completely dry);4. Put the special sand box on the 3D vibrating platform;5. Fill in low sand (dry sand) to vibrate and scrape;6. Put the dried blister gasification mold on the bottom sand, divide it into sand filling according to the process requirements, and scrape the box opening after automatic vibration for a certain time;7. Cover the sand box mouth with plastic film, put the pouring cup and connect the negative pressure system. After compacting, molten steel is cast, foam gasification die disappears, and molten metal takes its place.8. Release the vacuum after casting condensation and turn over the box to take out the casting for the next cycle.D. about UsDeXu Machinery Co., Ltd. is amachinery manufacturing and trading company.
