Otto Environmental Systems • 800 . 795 . OTTO ( 6886 ) • www.otto-usa.com Expert Engineering Otto strives to provide a breadth of products and services for its customers. Our engineering and product design team has the expertise to provide the best cost-effective solution to meet your needs for quality, durability, and longevity. Otto uses a plastic injection molding process using high density polyethylene (HDPE) to produce many of its products, including two-wheel carts, dumpsters, and contracted and custom molded parts. Injection molding provides consistency and durability with design features that are built into the mold to strengthen areas that face unique stress points. Otto containers are engineered with the appropriate balance of stiffness and flexibility to provide flex and conformity for an automated grabber, resulting in fewer stress points. Special features of our two-wheel carts feature a molded-in wear ridge at the bottom of the cart to prolong the container lifespan and patented dimples at four sides to assist with gripping power. Quality Management Otto Environmental Systems North America, Inc. is ISO 9001:2015, and IATF 16969:2016. Otto is regularly audited to maintain these certifications. Every order is inspected to meet specified project requirements. Otto carts are manufactured using high density polyethylene (HDPE). Otto only uses HDPE grades that have longer molecular chains to decrease the melt index and give the material “melt strength.” The higher molecular weight also gives the material increased environmental stress crack resistance (ESCR), impact strength, and cold-temperature toughness over a material with a similar density but shorter molecular chains. Each lot of resin is put through extensive testing to verify the melt flow index and check for moisture and contamination to ensure the resin meets Otto’s established standards. Advantages of the Otto Injection Molded Container Otto Environmental Systems North America, Inc. refuse containers are manufactured by an injection molding process. The injection molding process is capable of making products with complex designs that would not be possible by other manufacturing processes such as rotational or blow molding. For example: • HDPE (high-density polyethylene) composition is heavy duty and fully recyclable. • The automated manufacturing process yields lower container prices. • Injection molding allows for intricate design features, such as wear strips, support ribs, and assembly slots, where other molding processes create simpler outputs with limited mold design capability. • Consistency in wall thickness allows isolation of special features in order to strengthen areas where the container faces special stress, for example: o Lid attachments are cylindrical-shaped and double-ribbed, creating a robust attachment to the container body. o The container base is manufactured with a dual molded-on “wear strip” to take the brunt of the wear and abuse. The flat bottom of the container does not touch the ground. o Molded gussets contribute greater strength to the axle mounting details. • High pressure injected resin ensures complete and even coverage throughout the mold, providing overall consistent wall thickness and eliminating thin spots or “windows.” • An extra deep toehold assists with handling heavy loads.
