Authors: António Sergio Pouzada, Carlos H. Ahrens, Mathias G. Westphal, Gean V. Salmoria
The mechanical and thermal properties of the stereolitography resins,
used in the manufacture of hybrid moulds, differ substantially from those of the conventional
metallic materials.
c) Materials with solubility parameters close to that of the SL resin are likely to cause wear of the moulding core, due to chemical adhesion between the two materials during the injection phase, as observed by overmoulding the thermoplastic on to the SL block.

Along with the development of science and technology,and the progress of the society, the number of cylinders is growing with each passing day, and new material, new craft, new technology has been increasingly applied in the design and manufacture of the cylinder,to ensure the safety and reliability of gas cylinder[1].
Fig.1 Diagram of special high-pressure seamless gas cylinder There are many kinds of material which can be used to make gas Cylinders.We should think a lot about the mechanical properties, process performance and corrosion resistance of steel when choose the material of gas cylinders[3].Mechanical properties of the material, mainly control the intensity indexes: ultimate strength, yield limit and elongation.For the similar material, the higher the average strength, plasticity is relatively less.
The principle of choosing material of gas cylinders is that ensure the plastic index prescribed, at the same time, choose strength index of material as high as possible, to reduce the wall thickness and weight.Cylinder material, therefore, should has good plasticity, plastic material, when facing the cylinder damage will produce obvious plastic deformation, and it is easy to find and take timely measures to prevent damage and ensure safety.
Therefore we measure the strength index of the material (Alloy structural) through tests.
But due to the cylinder under high pressure, in order to do accurate calculation, we use the theory of thick wall cylinder to analyse.The figure 3 shows that for this materials = 815.80MPa.
