PLASTIC INJECTION MOULDING MACHINE FILTERS

Cooling water is a critical processing component of plastic injection moulding process. Siga Filtration can offer a range of products to remove scale and rust from recirculating cooling water used in mould tools of plastic injection moulding machines.

Recirculating cooling water accumulates corrosion products from mould and piping, contaminants from seals, sediment from makeup water, and scale due to incorrect water treatment. These contaminants can cause an uneven temperature on the mould surface and block mould cooling channels and heat exchanger tubes. Insufficient temperature control during the cooling cycle can result in inconsistent part dimensions, sink marks, poor surface finish, and warped sections. Whether you are using an open circuit cooling water system or dedicated chillers, a correctly sized filtration system will ensure efficient heat transfer, reduce cycle times, reduce rejections and keep your moulds performing at optimum levels. Please see our range of plastic injection moulding machine filters below.

BP/BN filter bags – 10″ & 20″ bags for PBH housings

BP & BN Series Filter Bags feature a thermally-welded, unique design that results in consistent filtration efficiencies. They are designed to fit the PBH-410 and PBH-420 Housings. Higher productivity can be achieved with faster bag change-outs. The semi-rigid cylindrical design is easily crushed and incinerated. BP Series (Polypropylene Felt) Filtration ratings from 1 to 200 microns to comply with any filtration requirement. Manufactured from felt due to its high solids loading capabilities versus similar mesh fabrics.  A glazed finish, created by melting the outermost surface fibers, is used to produce a bond that reduces the possibility of migration.  BN Series (Strainer) Woven monofilment materials are offered in nylon with micron ratings of 50 to 800. Efficiencies from 75 to 95%. Materials are cleanable and reusable.  View PBH bag housings for BP/BN filter bags View the complete range of filter bags View the complete range of food and beverage filters
