Different casting methods lead to different casting accuracy, initial cost andproduction rate are not same, final economical benefit are different, so in order toget more, faster, better, cheaper, we need to consider all the aspects. We shouldestimate preliminary cost for the casting method we may choose, to get higheconomical benefit and also ensure to reach casting requirements.

Different casting methods lead to different casting accuracy, initial cost and

production rate are not same, final economical benefit are different, so in order to

get more, faster, better, cheaper, we need to consider all the aspects. We should

estimate preliminary cost for the casting method we may choose, to get high

economical benefit and also ensure to reach casting requirements.

Although China’s foundry industry is in a difficult time, for the long term

perspective, China’s investment casting industry still have some hope, market

demand has started to be better, and the development of China’s casting

industry has solid strength. We believe China’s casting industry will get gratifying

results.

Experts said, we need to do following 4 points in order to improve casting

technology fundamentally:

Firstly, develop simulation technique, improve forecast accuracy, strengthen

process control, increase rate of yield. We can’t grasp regular problems very well,

it will affect production yield.

Secondly, combined production ,study and research together. independent

innovation of enterprise not only to strengthen consciousness of innovation and

improve research and development ability, but also need to pay attention to and

strengthen lost wax casting enterprise as the mainstay of “production, study, and

research” .

Thirdly, pay more attention to study and develop material. Material is the basis of


The accuracy requirement and cost of lost wax casting

industry, we still have a lot of work to do at present. In aerospace field, alloy

material, especially high temperature alloy and other new material, we need to

improve study and melting techniques, there is a big gap with foreign techniques.

Fourth, pay more attention to improve equipment technology. the main problem

is equipment, many key equipments, such as some directional solidification

equipments are mainly depend on importing, so it’s the key point to study and

develop the equipments of lost wax casting.
