ROTATIONAL MOULDING MACHINE

Image
  ROTATIONAL MOULDING INTRODUCTION ·          Rotational molding is a process of making hollow articles. ·          The part is formed inside a closed female mold. ·          In this process the mold rotates biaxially during heating and cooling cycle. ·          Rotational molded pieces are stress free because the pieces are produced without any external pressure. ·          The ability to manufacture large containers of capacity 30,000 gallons as well as small items like golf ball is responsible for the growth of this process. ·          The Process requires relatively in expensive equipment and exerts on only small pressure on the material being formed. PRINCIPLE ·          The principle...
