    LLDPE ROTATIONAL MOLDING

    Forte, Inc. has become one of the principal  LLDPE rotational molding manufacturers in the United States. Our many years of experience and knowledge allows us to service a diverse line of industries including, but not limited to, automotive, marine, commercial and industrial.

    Linear low density polyethylene or LLDPE, is a petroleum based plastic commonly used in rotational molding. A competitive approach to plastic manufacturing, the process consists of introducing a plastic resin in powder form into a hollow, shell-like mold. The molds are held by a machine arm that is engaged and sent into biaxial rotation, at relatively low speeds. As the plastic is heated, it forms a thin layer against the mold surface. After the cooling phase of rotation, the product can be removed from the mold. LLDPE rotational molding is used in a variety of applications, contact Forte to learn how we can help you achieve your specific end use.

The Rotational Molding Process

It is considered a most competitive approach to plastic manufacturing. The process consists of introducing a plastic resin in powder form into a hollow, shell-like mold. The molds are held by a machine arm that is engaged and sent into biaxial rotation at relatively low speeds. As the plastic is heated, it forms a thin layer against the inside of the mold surface. The wall thickness of the parts is controlled by the amount of resin poured into the mold which depends on its application. After the cooling phase of rotation, the product can be removed from the mold.
