New Finite Element Analysis (FEA) design techniques have been developed by Dotmar EPP specifically for application to plastic materials.
FEA consists of a computer model of a component or structure that is analyzed to determine the stress and deflections of a structure whilst exposed to different types of loading. It is used in new product design, and existing product refinement.
The new FEA technology can also be applied to the modification of an existing product or structure to qualify the product or structure for a new service condition. FEA can also account for visco-elastic behaviour of plastic materials over time.
Using FEA, today’s families of super plastics can be engineered such that long-term stresses, deflections and residual forces are known with a high degree of accuracy. This has enabled Dotmar to optimize design for low weight, high strength and very high impact resistance (attributes invaluable in applications as diverse as chemical vessels -both above and below ground, chemical scrubbers, flotation cells, anode/cathode filter frames, gears, sheaves, conveyors, impellers, wear resistant hoppers)
Dotmar has designed:
· 10m high flotation circuit sumps, manufactured completely out of high density thermo-plastic and able to withstand cyclonic wind loads.
· Steel reinforced PP-H pickling lines manufactured up to 26m long by 3.2m high.
· 8m high chemical scrubbers capable of supporting 10 tonnes of activated carbon.
· High Temperature Anode/Cathode filter frames
4m high by 3m diameter agitators with wear-resistant Matrox lining and baffles.
· 12m long self supporting, ‘non-stick’ launders shaped to provide constant surface velocity.
· Boat-lifting structures of completely thin walled sheet construction capable of lifting and balancing 6 tonne vessels.
· Horizontal circular or oval truck tanks of up to 4m diameter and 10 meters length.
