manufacture possibilities
Permanent moulding
Permanent mould casting method uses a steel permanent mould, the shell. These permanent moulds are assembled in hydraulic machines that help the worker to move the different parts of the tooling and extract the part alter melting.
It is recommended for long batches, among 300 and 15.000 parts per month, and weight from 0,05 and 35 Kg.
Manual moulding
Chemical manual moulding process creates sand moulds, which are hardened through chemical products. These moulds are used only once, because they are destroyed when extracting the part after melting.
It's recommended for short series, defined in function of the part's specification, with weight from 1 and 2.500 Kg.
Carousel of moulding
Carousel moulding process creates one sand mould per each part, getting hardness though dampened bentonite clay. This way, the desand of the part can be done easily with mechanical vibrations, so the process can be automated.
The whole sand characteristics are controlled with an higrometer from a control panel.
Raw material
Cofundi manufactures top quality products, which requires primary aluminium of the highest quality from a global supplier such as ALCOA Inespal.
In the same way, we are used to melt with a great variety of different alloys, among them.
Finishing
Cofundi can offer in our products any kind of finishing. After melting, all external elements that should not be in the part, shuch as feeders or channels, are removed. At this stage, we take the parts to our finished plant.
There, firstly we go on with the surface processing removing all shape edges, before starting the required finishing procedures. Among the most frequently used finishing processes: sand or steel ball blasting, polishng, anodizing, painting, assembly, machining or heat treatment.
Before ending, all the parts are inspected, packaged for the delivery and quality and logistic documentation is created, always according to customer requirements.
