Space winding helix parametric equation, metal rubber and its blank meso structure numerical model were established with real raw material and process parameters of product based on automatic blank twine technology. Forming force, mould friction force, mould stress, product size, springback value, solid phase volume fraction, contact point number, material meso structure and tissue distribution were predicted by numerical model. Forecast results are coincident to experiment. Numerical model is physically significant and reliable definitely. The model is directive for manufacture of metal rubber and makes it possible to research metal rubber in meso scale.
