    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.

    NYLON INJECTION MOLDING
    Nylon injection molding is just one of the molding capabilities you’ll find at leading plastics manufacturer Forte Products. Our Kansas injection molding machinery ranges in size from 28 to 1000 tons, allowing us to manufacturer plastic parts of many sizes and scales. We are happy to discuss nylon injection molding ideas with each client to ensure the process and materials are an ideal fit for your project.

    APPLICATIONS FOR NYLON INJECTION MOLDING
    Nylon material is used in a large range of different industrial applications because of its impressive mechanical and electrical properties, excelling in toughness, wear resistance and chemical resistance.

    Nylon injection molding produces plastic parts that are used in countless industries and applications, such as:
    • Consumer apparel and footwear
    • Sports and recreation equipment
    • Industrial components
    • Medical products
    • Automotive products

    As nylon has great bending strength, it lends itself well for parts that will be intermittently loaded. Furthermore, with the high wear resistance and low coefficient of friction, nylon works well in applications such as slides, bearings and any device that is put through motion.

    NYLON PROPERTIES
    As a thermoplastic, nylon has a high level of heat stability, which contributes to its strength. The material is also resistant to a number of external factors, including:
    • Abrasion
    • Impact
    • Chemicals

    EXCELLENCE IN CUSTOM DESIGN
    Forte is a top U.S. injection molder committed to customization and superior craftsmanship. We work closely with our clients to ensure our nylon injection molding meets or exceeds your individual specifications. If nylon is not the right material for the job, we’ll discuss other injection molding options until we find the appropriate and cost-efficient design plan.

    POLYETHYLENE INJECTION MOLDING
    Forte entertains high volume production runs as well as low volume production runs with injection molding machinery ranging in size from 28 to 1000 tons. Depending upon your budget and application, polyethylene plastic may be the most economical material option for your next project.

    POLYETHYLENE PROPERTIES & DENSITIES
    In general polyethylene is light in weight and possess strength, chemical resistance, impermeability and impressive electrical insulating properties. Furthermore, the economic cost of the material makes it an excellent material for disposable and recyclable industrial product applications, whilst it's comparative low density enables more volume of plastic to be processed.

    Polyethylene is available in many different densities:

    • High density polyethylene (HPDE) – a food-grade plastic.
    • Low density polyethylene (LDPE) – the first grade of polyethylene to use a high-pressure process with free radical polymerization.
    • Linear low-density polyethylene (LLDPE) – differs structurally from LDPE because it has short branches and LDPE has long chain branching.

    The higher the density of the polyethylene material used the stronger, more rigid and more heat resistant the plastic is. The higher density models show better properties in tensile strength, chemical and heat resistance, surface hardness and abrasion resistance. HDPE for injection molding works well in both hot and cold temperatures and has a tensile strength of 4550 pounds per inch.

    BENEFITS OF POLYETHYLENE
    • High levels of ductility
    • Tensile strength
    • Impact resistance
    • Resistance to moisture absorption
    • Recyclable

    INDUSTRIAL APPLICATIONS OF POLYETHYLENE
    The versatility of the polyethylene makes the material an ideal choice for the following industries and products:

    • Agricultural products
    • Lawn and Garden products
    • Heavy construction
    • Consumer products, including toys, food containers and garbage receptacles
    • Plumbing products
    • Medical products

    POLYPROPYLENE INJECTION MOLDING
    Polypropylene, sometimes referred to as pp, is a synthetic resin used in our injection molding for a wide range of applications. Polypropylene is one of the lowest density plastics; the density ranges between 0.895 and 0.92 g/cm. Polypropylene is safe for use as food containers because polypropylene does not leach chemicals into food products. Trust Forte for all your polypropylene injection molding needs. Forte Products offers a variety of plastic polypropylene injection molding services to create parts and products of all shapes and sizes. Our fleet of injection molding equipment ranges from 28-ton machinery for smaller components to 1000-ton machines suitable for large parts.
    Polypropylene is used in lots of other applications including; household goods, automotive products, marine and RV products. Below is a list of some of the benefits of choosing polypropylene for your molded plastic parts:

    WHY USE POLYPROPYLENE FOR INJECTION MOLDING?
    • Excellent moisture resistance
    • Mold in or “living hinge” capabilities
    • Food grade availability
    • Excellent impact strength
    • Chemical resistance
    • Low cost

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.
