Cloth neck types are a very important parameter that can greatly affect the efficiency of filter press operations and save on maintenance time.
In addition to fabric design (yarn fiber materials, yarn types, weave patterns, weaving process), feed neck choice plays a critical role in helping customers achieve optimum filtration performance in their filter press operations.
Welded HPR Feed Necks
Micronics’ proprietary, patented, welded high-performance rubber (HPR) design delivers many performance advantages to filter press operations. Our HPR feed neck utilizes thermoplastic rubber compounds and a controlled-temperature welding system to attach the feed neck to a polypropylene filter cloth.
Micronics’ welded feed necks cannot leak or bypass product through stitch holes, ensuring that there will be no sudden failures and yield losses when you are filtering expensive products.
Micronics’ HPR feed neck is fully resistant to high velocity, abrasive slurries, and to all chemical conditions.
In addition to the HPR design, there are other high-performance filter cloth neck types such as the SK neck design, heat-treated coated neck design, and clip neck design. Other special vinyl-coated and FDA coated neck designs are available when required.

SK Feed Necks
This new patented product allows rigid, plastic necks to be attached to polypropylene cloths. The performance benefits are the same as with the HPR design with the additional advantage of high abrasion resistance for difficult slurries. Micronics’ abrasion-resistant design leads to longer filter cloth life for better operating economics.
Heat-Treated Coated Feed Necks
For applications where cloth attachments are desired, a heat-treated coated neck should be selected. This neck type uses synthetic rubber formulations, and is determined by Micronics to be chemically-stable and abrasion-resistant. They will always outperform hand-applied treatments.
This is a patented, Micronics-designed neck used in conjunction with special plate modifications, allowing the use of single filter cloths. This innovative design reduces cloth changeout times, lowers overall cloth costs, and improves filter press operations.
