In the precision casting wax, in its mode and method of choice, what should be considered? And, for the casting of black metal, precision casting, applicable? In precision casting, and in the choice of the methods, should be considered, mainly for the method of adaptive, and, whether can use equipment, using advanced modelling or build core technology, to improve the work efficiency. For the casting of black metal, it can be used precision casting. Moreover, according to the characteristics of the casting, it can be used to produce some thin-walled castings.
Precision casting molds, what do we call them? And, are parts made by precision casting required to be machined? Precision casting mould, for this kind of mould, we call it precision casting mould, and it is the exclusive mold of precision casting. The parts produced by precision casting do not need to be machined. Because, precision casting, it belongs to special casting, in casting dimension, it has very good accuracy, can achieve high standards and requirements.
The machining process of waxless casting has high dimension precision and clear external profile. The casting surface is smooth and clean, and the appearance quality is good. However, good products are bound to be inseparable from good technical level, so how does wax loss casting allow processing? Take the wax mould that has been statically set for 3-6 hours and has passed the test for important dimensions. Check whether there is any defect in these wax models. If there is any defect, it should be removed.
Repair the mold to remove the residue on the wax models or parting line, use the blade edge along the wax models carefully and gently cut off flash or parting line, shall not damage the wax models, for a small flash can be directly with cloth wipe. Wax mold concave repair, wax mold on a large and long concave application repair wax repair, after the repair surface to be smooth. Bubble is fixing the wax models all bubbles must prick, repair, wax, shape to correctly after repair, repair flow mark with trichloroethylene cotton wipe gently with a sucker flow mark, to remove the flow mark, be careful not to hurt the wax pattern itself.
Insert ceramic core, for some wax models with ceramic core, be careful to slide the ceramic core into the melting (wax) hole. The sharp Angle on the ceramic core must be avoided to scratch the wax mould. Use cotton yarn or cotton with trichloroethylene to gently wipe away the wax mold oil and wax coating. The repaired wax mould should be placed on the joint of the mould delivery module in the storage plate as required and ready for use.
