Welcome to inquire! Contact: Yuan Xi Chuan. Casting machine equipment in a large proportion of liquid molding parts, machine tools, internal combustion engines, mining machinery, heavy machinery in liquid molding parts from 70% to 90% of the total weight; 50% to 70% in the car, tractor; accounting for 40% to 70% in the agricultural machinery. Liquid molding process can be so widely used, because it has the following advantages: (1) can be manufactured lumen rough shape very complex. Such as various cabinet, machine bed, cylinder block, cylinder head and so on. (2) process flexibility, wide adaptability. The size of the liquid molding parts virtually unlimited, its weight by a few grams to several hundred tons, and its wall thickness by about 0.5mm to 1m. The industry who can melt into liquid metal material can be used for liquid molding. For poor cast plastic cable trough, liquid molding is the only way to produce it blank or parts. (3) liquid-form lower cost. Direct use of waste liquid molding parts and chip cable ducts, lower equipment costs. Meanwhile, the liquid molding pieces small allowance price of cable trays, saving metal. Casting car cover, machine bed and other large mold than traditional sand has a great advantage, it not only eliminates the need for expensive wood-based costs, and ease of operation, shorten the production cycle, improve production efficiency, high dimensional accuracy, allowance is small, good surface quality and other advantages; In addition, casting machining has good wear resistance and anti-shock performance and good process performance.
