Selecting the Right Hotwire for Your Specific EPS Application

Whitepaper – February 2016

Gateway Precision Technologies, LLC “Gateway”, a Hunkar Technologies’ Company, has been providing premium hotwire and related componentry to the EPS industry for over 30 years. Recently, there has been industry discussion about the benefits of using certain narrow gauge hotwire diameters and this white paper seeks to clarify the important aspects of why utilizing only high quality hotwire and only utilizing the proper wire diameter are both critical to maximizing the performance and efficiency of any EPS processing application.

Too often of late, operators are choosing, in an earnest attempt to save their company money, the cheapest wire they can find and in the smallest diameter produced. Frequently these wire products can be found on websites of upstart companies whose personnel have little knowledge or experience in the EPS Industry. Cheaply made hotwire often wears quickly resulting in less processing up time.  Choosing too narrow a wire diameter such as .010 can result in excessive breakage, slower run speeds, insufficient heat conductivity and greater energy use in EPS processing non- batch continuous environments. In addition, applications where substantial regrind is used in block formulation, narrow wire diameters can result in excessive breakage due to unusually strong product cellular characteristics making the product blocks somewhat more resistant to hotwire cutting. This characteristic can be particularly relevant in slabbing and down cutting applications.

The following are Gateway’s technical recommendations for hotwire diameters based on machinery selected and applicable EPS industry applications:

Slabbers or Short Wires on a Down Cutter. Wire length less than 60”                .012 or .014 Dia.          2.75” Spring
 
Contour Cutters with Wires less than 144”                                                           .014 Dia.                        2.75” Spring
 
Contour Cutters with Wires less than 60”                                                             .012 or .014 Dia.           2.75” Spring
 
Down Cutters with Long Wires less than 144”                                                      .014 Dia.                        4.00” Spring
 
Down Cutters with Long Wires greater than 144”                                                 .014-.020 Dia.               4.00” Spring
 
Gateway Gp-11000 Autowire Slabber                                                                     .012-.014 Dia.               2.00” Spring
 
Gateway Gp-2103 Autowire Down Cutter Short Wire                                             .012-.014 Dia.               2.75” Spring
 
Gateway Gp-2103 Autowire Down Cutter Long Wire                                              .014-.018 Dia.               2.75” Spring
