D3 Engineering Cad moulding
A top quality CAD moulding displays an excellent finish and no defects. This is made possible by the latest leading-edge CAD applications, like AutoCAD, running on a powerful computer that allows top engineering consultancies like D3 Engineering Solutions to create a virtual CAD moulding, perfecting the design even before the mould has been created. The virtual mould can be viewed from all angles in 3D on the computer screen even before it exists.
A moulding is created by injecting a hot material in its liquid, molten state into a mould. Although glass and metal moulds are common enough, plastic is the most popular moulded material, because it is so versatile. The actual mould consists of two halves, the injection mould and the ejector mould. They are fastened together and they form a cavity in the shape of the article to be produced. The molten material is injected into the mould; at the same time, air escapes through specials grooves and coolant is circulated through the mould body to cool down the material and encourage it to harden. Trapped air can burn the moulding under high pressures and spoil it.
The mould features are purposely designed to not overhang each other in the direction in which the mould will open. The injection mould comes off first and the ejector mould retains the moulding. The moulding is removed, the line left by the two halves is de-burred and smoothed and the article is finished.
A CAD moulding that emerges from such a high-tech design process is flawless and cost-effective. D3 Engineering Solutions can design moulds for any application, in any material that can be moulded. We also do Design for Manufacture, to ensure that the product is as cheap to produce as possible, while meeting all quality criteria. Contact us for more information.
