Easy Production of Greener Plastic Pipe
Using recycled plastic materials offers pipe manufacturers an advantage in terms of cost savings on pelletized plastics. However, using recycled plastics is not possible without the proper production equipment for producing safe and high quality plastic pipe.
The 3 layer head produces pipe with a center core comprised of recycled material, while the inner or outer layers are produced using virgin raw material. This reduces the use of expensive virgin materials by using lower cost or recycled materials without jeopardizing the integrity and functionality of the manufactured pipe.
Recycled pipe can come in a few different configurations when using a 3 layer head. The two primary configurations for recycled pipe manufacturing are ABA and ABC; each letter refers to a different material/layer used in the pipe.
The Different Types of Low Cost Recycled Materials
There are a number of different types of recycled materials; below is a breakdown of a few different options available on the market.
Self made scrap: Every plastic pipe factory produces a certain amount of scrap product that is frequently discarded. Manufacturers who can repelletize scrap material can return the pellets to the manufacturing process and save money by making use of scrap pipe.
Purchased recycled materials: Recycled or repelletize materials are available at a fraction of the cost from recycling plants all around the world. A 3 layer head allows the use of such materials in the pipe production process, as another way of reducing material costs.
Off spec materials: The plastics industry regularly produces off-spec or off-grade plastics. These are normally found during the startup of the production at the plastic manufacturing facilities until process stabilizes. Such lower grade plastic is sold at a much lower cost compared to virgin material, and can readily be put to use in manufacturing plastic pipe when using 3 layer head technology.
Additional Benefits of a 3 Layer Head
The 3 layer head’s operation is best complemented by a gravimetric feeder system, assuring steady and continuous feeding of the extruder and ensuring consistency. The gravimetric system controls the precise thickness of each layer in order to assure proper pipe structure. This results in pipe produced within specification and having the same material consistency throughout despite the use of recycled or off-spec materials.
Using recycled materials can give plastic pipe manufacturers unique products while allowing them to save money on material, all without compromising the quality and integrity of their product.
