The use of lost wax casting characteristics can produce thin-walled parts

FOR IMMEDIATE RELEASE
(Free-Press-Release.com) July 21, 2010 -- Lost wax casting with conventional casting, forging, mechanical cutting, shaping method does not have features and benefits, and the application of any material and more flexible production capacity, so lost wax casting applications cover a wide range of aircraft from the sky, the ground vehicles, marine vessels to the industrial machinery and equipment and art supplies can be contracted to leisure.

Xin Yi Precision Industry Chenwu Hong, general manager, said the use of lost wax casting characteristics can produce thin-walled parts, complex shape parts, pattern precision parts, process complex parts, hard machining parts, net-shaped parts, materials expensive parts, and several parts forming one, and good dimensional accuracy and surface brightness. Especially difficult using traditional sand casting, forging method or a method of manufacturing cutting bizarre, hollow, complex parts, and although you can use the forging, machining and other methods of manufacture, but many processes, require a lot of machining, low productivity, but also will spend a lot of metal materials, resulting in high manufacturing costs of parts, use lost wax casting, can be achieved with short duration, low cost and purpose.

On the fine pattern, fine groove, bending pore components, but also save hours of work EDM and laser engraving and costs and expenses. In addition, the use of lost wax casting method most suitable for manufacturing net shape (Net Shape) parts, can significantly reduce part weight, can also be cast together in several parts to reduce weight and improve the mechanical properties and dimensional accuracy, and reduce the number of working hours and reduce costs.

Local production of precision castings dewaxing maximum limit length 700mm, 200mm in length and easy to do the following. Maximum weight of casting is about 100 kg, 10 kg less to commonly used as casting, casting less than 30 kg. Casting tolerance of about 20mm ± 0.13mm, 100mm ± 0.30mm, 200mm ± 0.43mm, and small pieces of dimensional accuracy of ± 0.10mm within easy reach. Angle tolerance of ± 0.5 ~ ± 2.0 degrees, casting the thinnest wall thickness can be 0.5mm. Casting surface roughness of about Rmax 4S ~ 12S.

Precision dewaxing casting is also characterized by active material, a few without any limitations, such as cast iron, cast steel, alloy steel, stainless steel, tool steel, aluminum, magnesium alloys, titanium alloys, copper alloys, beryllium copper alloys, super alloys, Cobalt and nickel base alloy, etc., any applicable co-metals. Zhang never said that any line of lost-wax casting alloy can, if you encounter a particular part of production, the alloy is difficult to cut or not cut, the general lost wax casting is the best method of production of the parts. And some alloy is more suitable for lost wax precision casting production, will be more efficient, more perfect, such as the complex combination of parts can be cast out fine hole, ditch, diagonal, jagged, notched, thin section, cut, and other forms, due to size good accuracy, more than 90% can be used without further processing, so that milling, turning, boring and other machine tool can be completed without refining, product development, design can be extremely flexible.

Zhang always that prompted many buyers from other manufacturing methods changed to dewaxing casting motivation, it can be significant savings, in general, manufacturing cost reduction ranges from about 50% or more, and for a variety of mass production. A wide range of applications including: gas turbines, steam turbines, aircraft parts, internal combustion engines, vehicle parts, ship parts, medical equipment, golf head, food machinery, printing machinery, paper machinery, compressors, valves, pumps , measurement instrument, sewing machines, weapons, business machines and other machine parts.
