China Aluminium Die Casting – Dimensional Accuracy Very Critical
Components made by die casting play a vital role in many key industries of the economy. Aluminium as a metal offers a number of advantages. One of them is that the metal is light but quite strong, and one can get very accurate components through china aluminium die casting, provided the molds are of good quality.
Choice of Aluminium as a Material
As mentioned, aluminium is the metal using which many components get made. The process of die casting with this metal requires skill and expertise and is cost effective. The technology has advanced to a great extent, and the moulds are generally made from a steel material. The pouring of aluminium into the moulds under pressure is done to fill the mould, and the casting machines have the provision to set the right temperature at which the casting takes place. The products that come out of the machine are almost perfect and hardly any finishing work has to be done on them. The industries which use the China aluminium die casting machines to manufacture the components, have a choice of machines and the sizes and types of components that will determine the final design and specifications of the machines. What is more important is also the quality of the molds.
Mold also Made by the Machine Maker
The process of die casting requires the machine to be of the best quality and the steel molds also have to be manufactured to perfection. The china aluminium die casting moldmaking companies take care of this aspect also, and the best quality moulds are made by them. In making these moulds, the factors that are considered include dimensional accuracy. To get this right, the China aluminium die casting moldmaking companies first obtain the drawing of the components that have to be made from the moulds. If the customer can give the actual compound also, it helps in making the molds with better accuracy.
Obviously, if the component is being developed for the first time, the customer might not be able to provide the sample piece. The rough piece developed by the design department might not represent the actual specification. The key technical factor kept in view is the coefficient of expansion of the metal of the mold. At the time of die casting, the machine expands when the aluminium is poured and then when the component is taken out after cooling, the accurate dimensions are achieved. Every reliable China aluminium die casting moldmaking company takes care of all these technical parameters to ensure that their customers receive the best moulds. Hence, the components that they then cast using these moulds, pass all tests and are approved by the end users.
