Needle boards

Properties

Needle boards are plates consisting of a metal body and a plastic coating (on one or on both sides) with many small holes, where felting needles are inserted. Those boards are used in machines to produce fleece. Asma produces extensive PU coatings on metal support plates which are provided by the customer. Further processing is undertaken by the customer. (Drilling, milling, …)

Application

  • The wear resistant coating made from PU elongates the plates´ service life.
  • Facilitation of the plates´ manipulation

  • Using swelling tests, the most resilient PU type can be chosen
  • The optimal connection of PU coating and basic body is important
