Megadyne employs several processes for applying covers and coatings to belt substrates. The choice of process is predicated on factors which include substrate selection, cover material type, quantities needed, application dynamics and project economics. Megadyne sales personnel and application engineers can assist in helping choose the right materials and processes for your application.
At Megadyne we can mold uncured rubber, extrude thermoplastics, laminate rubbers and thermoplastics and coat belts. Depending on your need, we’ll provide the right process and product.
Molded Belt Covers
Starting with uncured rubber blended to our specifications, we extrude onto synchronous or non-synchronous substrates, cure and grind to your finish specification. Our process creates a belt without bumps, splices, seams, or hard spots, while drastically reducing delamination, increasing belt life, and creating uniform wear surfaces.
In addition to many standard rubber materials for molding, Megadyne Belt Corporation has developed its proprietary DuraTaq™ compound, which offers a high coefficient of friction and low wear resistance. It’s the perfect choice for applications requiring superior wear performance in difficult abrasion settings, leading to extended life and greater machine uptime performance.
Molded covers can be further modified with holes, slots, ground impressions, grooves, pockets and other designs to assist in enhancing product handling and movement. See our modification page for additional details.
Megadyne offers both Thermoplastic and PVC covers that can be extruded onto the convey side of Megalinear and Megaflex during base belt extrusion. This process ensures a homogeneous bond of both the cover and the timing belt. Minimum quantity runs apply to this option.
Fabricated Laminated Covers
Where quantities are smaller, Megadyne offers a method of adding both thermoplastic and rubber covers onto synchronous or non-synchronous base belts using a unique Fabrication/ lamination method. This process provides high-quality bonding of the cover to belt and a fast response to market inquires.
Coatings for Belts
Megadyne can coat silicone or neoprene to a wide range of belt substrates, both stable and elastic, narrow or wide, synchronous or non-synchronous. Coated belts are commonly used in product transport applications where environmental conditions such as temperature would have an adverse effect on fabricated covers. Additionally, the coating of certain material substrates allows for the finished product to move across low-profile conveyors where designs such as knife-edge pulley transports are common.
FDA silicone materials allow ease of cleaning and release in applications such as that of hygienic goods and medical related parts and components. Silicone is an excellent cover material where the use of glues and adhesives are present in product manufacture, such as diaper manufacture.
Neoprene rubber can be formulated to provide good chemical and wear resistance, anti-static features, and self-extinguishing (UL94V) non-flammable properties for use in precision conveying applications. Our Neoprene Rubber Coatings can be applied to various substrates.
Coated belts can be further modified with holes to assist in vacuum draw applications.
