Porous plastic functional component for a wide range of applications 

Yamahachi porous nibs & tips have great characteristics such as flexibility, absorption, hydrophobicity and application.

With our porous technology, we offer our support for your porous products to meet the challenges of your development. To ensure total satisfaction in terms of Quality, Cost and Delivery (QCD), we have established an integrated production system in our own factories, covering all production processes.

 Benefits 

When using fiber as the base material for a porous product, you may have some problems with fraying on some parts of the product. Here is an answer! We use polyethylene (PE) as the base material and there is no risk of cracking or fraying.

There is a wide range of shapes that can be produced using our engineering technology, for example, tubes with unique shapes, asymmetric shapes and more.　We can also offer secondary operations such as the assembly of porous tips with ink feeder as an additional option if required.

Three-dimensional network fine continuous porous structure.	Various shapes and assembling to feeder available.	Also available in hollow shapes and small sizes.	Flexible porous tips/nibs.	Absorbs oil and ink. Great for oil and/or ink applications.
