Background technology
Die casting is a kind of metal casting technique, is characterized in that the metal using mold cavity to melting applies high pressure, and mould leads to
It is often to be processed with the higher alloy of intensity, this process some similar injection mo(u)ldings, most of die casting foundry goods are all not
Iron content, such as zinc, copper, aluminium, magnesium, lead, tin and terne metal and their alloy.According to the difference of die casting type, need
Will be using cold-chamber die casting machine or hot chamber machine.
In automobile making and household electric appliances, there is many parts for using aluminium die casting, the part of each aluminium die casting from
Project starts that in design, manufacture process the price estimation in terms of cost and cost calculation will be carried out, this aluminium diecast parts
Cost estimation for the profit index of whole part, part and project play the role of it is important.Aluminium die casting cost estimation
Accuracy and cost time, the production cost and production time to enterprise of both parties, and whole project have larger
Affect.
Existing aluminium die casting cost estimation, one kind is part cost of raw and processed materials plus part die casting expense, the die casting of part
Expense according to the algorithm in industry, such as using how much mould of 400 tons of die casting machines, using how much mould of 500 tons of die casting machines,
Among these and either you are with being exactly so quotation in what brand die casting machine, industry, and this basis estimated mostly is
The enterprise of manufactured parts oneself estimates the die casting machine using what tonnage.A kind of is experience of the die casting producer directly according to oneself,
Directly report a price；Other is exactly that raw material are directly multiplied by a coefficient, then obtains the price of an estimation.These are estimated
In calculation, the die casting machine of how many tonnages how is selected without offer, without the utilization rate, the energy consumption of aluminium water that calculate aluminium water in detail, do not had
There is the process time for analyzing each mould, without the thin item of deburred etc..In a word, existing aluminium die casting cost estimation and calculating,
All it is individual module separate computations, without the system-computed method that the product of being cast into are expected comprising a whole former material.
