Spin Pack filters

A Spin Pack Filter screen also known as a polymer pack filter can be described as a Multi-layered wire mesh screen clubbed and bound together using a Ferrous and Non-Ferrous border.

In the bunch of different wire mesh screens, the finest filtration screen is usually placed in the center and the coarse mesh which is a supporting screen is successively placed facing the outer sides.

Spin Pack Filter Screen is an imperative part of the melt filtration and extrusion process. It effectively helps to avoid the mixing of foreign particles from the extrusion process and provides a clean extrusion for plastic and polymer processing machinery.

Nomenclature of Spin Pack Filters

We manufacture the finest spin pack filters as per the specification and technical drawings are given by the customer. It’s important to study the below-mentioned details so as to produce filters as per the requirements.

LAYER: Single or Multi-layered.

WIREMESH MATERIAL: SS 304, SS 304L, SS 316, SS 316L.

BINDING BORDER MATERIAL: Aluminium, Copper, Brass, and Stainless Steel. The binding border and its material grade are very important. If a cheaper or non-standard material is used, it will cause damage to the spinneret and may also lead to the infiltration of foreign particles.

SHAPE: Circular, D-shaped, Square, Oval, Rectangular, and another special shape as per the specification.

 DIMENSIONS: The most crucial expectations of a mechanical part are the dimensions and the working tolerance. The Spin Pack Filters are fitted on the Spinneret of the extrusion machine and it is very important to maintain dimensions. If the dimensions are not maintained, either it will not fit on the Spinneret or it might cause leakage in the process.

FILTRATION MEDIA: There are two types of filtration Media, which are used depending upon the application of the user. The same is specified below:

  1. Wire Mesh: Plain Weave, Plain Dutch Weave, or Twill Dutch Weave Mesh as Per Filtration Requirements.
  2. Metal Fibre Sheet (Non-Woven): Certain applications require higher dirt-holding capacity under high temperatures and pressure, we suggest using metallic fiber felt for better performance.
