About Us

The aluminum liquid distribution bag produced by Shandong Ningjin Bohan Machinery Co., Ltd. has been specially selected, designed and woven to ensure that the yarn and mesh of the distribution bag are uniform and prevent the pressure or flattening caused by the contact Deformation, especially suitable for splitting and filtering of molten aluminum in large furnace slabs. The company has passed ISO9001 certification. Each batch of products is tested to check its burning loss, stiffness and mesh size to ensure the stability of product quality.

Advantages

1. "Bohan" brand Filter bag size: outer bag: 13 * 5 * 6 (inch); inner bag: 8 * 5 * 6 (inch);

2. "Bohan" brand filter bag strength standard: under normal aluminum casting environment, the filter bag can be maintained intact without obvious deformation for more than 4 hours;

3, "Bohan" brand filter bag high temperature resistance: can withstand 900 degrees of high temperature, can ensure that contact with the aluminum liquid during firing does not occur, no obvious smoke;

4, "Bohan" brand filter bag appearance standards: after special treatment, to ensure that the filter bag appearance size, rigidity, uniform mesh size, fine sewing workmanship, no burr.

Introduction

Fiberglass filter bag is designed and woven specially for  aluminium diffusion and filtration. High twist yarns are used to control strand diameters and resist flattening or distortion under the pressure of contact with molten metal. Applications for large particle filtration for wash reduction include trough socks, channel bags, launder windsocks, spout socks and combo bags.

Application:

--Standard three strand for regular alloys in standard temperature range

--Four and six strand construction for long cast, aggressive alloys, slightly higher temperature range, or when more strength is required

--H-20 glass yarn for extreme demand and higher temperature applications

--Woven fabrics, offered in a variety of weaves and coatings, available as custom made pre-sewn shapes, with or without gaskets or wires, or in roll form

--Modifications can be made at the weaving stage to meet specific requirements
