WHAT IS LOST-FOAM CASTING?

　　Lost foam casting(also known as solid casting)is to bond and combine paraffin or foam models similar in size and shape to castings into model clusters.After brushing and drying refractory coatings,they are buried in dry quartz sand and vibrated for modeling.It is a new casting method in which castings are formed by pouring down to vaporize the model,liquid metal occupies the position of the model,and solidifies and cools.

　　THE CHARACTERISTICS OF HNYB LOST-FOAM CASTING

　　1.Good casting quality and low cost;2.Unlimited material,suitable size;3.High precision,smooth surface,less cleaning and saving of machining;4.Great reduction of internal defects and compact structure of castings;Scale and mass production;6.Suitable for mass production casting of the same castings;7.Suitable for manual operation and automatic assembly line production and operation control;8.The production status of the production line meets the requirements of environmental protection technical parameters;9.Can greatly improve casting The working environment and production conditions of the production line,reduce labor intensity and reduce energy consumption.

　　WHAT MATERIALS CAN BE CAST USE LOST-FOAM CASTING?

　　Gray cast iron,non-ferrous alloy,common carbon steel,ductile iron(Nodular cast iron),low carbon steel and other.
