Injection Mould for Styrofoam Box

Hello, I am looking for a company who makes injection moulds for styrofoam elements. I am interested in mould for styrofoam box. The box will be made of two parts: - top 315x225x30mm - bottom 315x225x20mm These two elements will be put one on the other so the closed box will be formed with dimension 315x225x43mm. If Your company deals with injection moulds and You can manufacture such a mould for me please contact with me. I will then send You a 3d model of ready box wchich has to be made with this mould. Regards Lukasz frater
