Cumberland is a long established brand name plastic granulator manufacturing company. The plastic granulators made by Cumberland have filled an important role in auxiliary equipment for plastic manufacturing industry for many years. Cumberland plastic granulators are used side by side with plastic injection molding machines and blow molders.
Cumberland makes many types of plastic granulators. There are several different subsets that make up the complete line of plastic granulators and grinders, and choosing the right one can have a profound impact on the ability to create desired results. These three categories of plastic granulating machines have different purposes and fit different needs - choosing the right one is essential to best achieve your desired purpose.
"Beside the Press" Cumberland Plastic Granulators
When plastic injection molded or blow molded products are manufactured, parts are made by melting plastic pellets into a viscous liquid state, then injecting this liquid plastic into a mold. The molds are constructed with channels to allow the plastic to flow into all corners of the mold. When the plastic hardens, these channels are filled with hard plastic that is called sprue. The sprue is broken or picked off the parts by humans or robots. This pure plastic is dropped into a granulator to be converted back into pellets that go right back into the injection molding machine to be re-melted and made into new parts.
These "beside the press" style plastic granulators are designed to fill needs for the injection molding market when it comes to scrap reclamation and similar processes. From small runners and sprues to large and finished parts, these plastic granulating products can get the job done. The recycling happens right at the machine lowering the injection molder's raw material cost and eliminating the need to dispose of waste material. The reprocessing and reclamation of these materials can save a significant amount of time, money, capital and even landfill space.
"Under the Press" Cumberland Plastic Granulators
The under the press style plastic granulating units are designed to be auger fed for the purpose of thermoforming applications, injection molding and web processing, primarily within the thermoform industry. Through the reclamation of this material, which can be quite valuable for many applications, environmental resources as well as financial resources can be effectively conserved.
"Central" Cumberland Plastic Granulators
The purpose of these central style granulators is to serve as large units, and they have been designed primarily for the reclamation of larger volumes of material or larger size materials. They are typically installed in strategic sites that are convenient for a particular manufacturing application, and as such, these units are able to process much larger quantities of plastic and resin for the purpose of selling or reprocessing. There are a wide variety of different units that can be purchased and utilized in order to meet the unique requirements for any manufacturing facility. These large size machines can also be used to recycle refuse plastic, like PET bottles (soda bottles) or the like.
