What is 3D Modelling?

How We Use 3D Modelling

Special software allows us to plan out and accurately represent the object we have in mind. Connecting geometric shapes, curved surfaces, and lines, the 3D model gives a mathematical description of the surface of the object. Here at GMT Rubber, if standard products are not suitable to a client, we are able to produce a new design using 3D modelling. This is used in conjunction with Finite Element Analysis (FEA).

With knowledge of the client’s needs, we build a product to meet the specification whilst ensuring that the finished design is also capable of meeting service life/durability requirements.

The method of 3D modelling is used in conjunction with Finite Element Analysis (FEA) to further validate and finalise the development process. FEA is a computerised process that helps to predict how a product will react to forces when the product is actually used. This method involves breaking an object down into many finite elements. Mathematical equations are then able to assess the behaviour of each element if the product were to be made. In terms of how this is relevant to our products, we use FEA to predict and minimise areas of stress concentration. This allows us to manufacture the highest quality products that will work at maximum efficiency.

After the 3D modelling and FEA process, the 3D CAD model produced is then used to develop a mould to bring the designed product to life. GMT’s experienced tooling design engineers have to consider many factors in this process. This includes the fact that the mould has to be larger than the finished part to allow the rubber to contract as it cools after vulcanisation.

Benefits of 3D Modelling

There are numerous reasons as to why 3D modelling is used in the creation of bespoke parts. Importantly, a 3D Model really brings an object to life, improving the visualisation of a new object. The software also saves a lot of time in terms of the development process. Drawings by hand would take time and are susceptible to human error. Furthermore, more designs would need to be produced to represent the full effect and detail that can be seen using a 3D model.

The whole process involved in creating a new product requires expertise and knowledge. With the help of 3D Modelling and FEA, the process is efficient and accurate. GMT produce a wide range of high-quality anti-vibration products, suitable to a variety of industries. If you would like any more information, do not hesitate to contact us.
