Know-How
Key Applications
Our fine steel meshes are mainly used for applications in sieving and sizing, filtration, screen printing and screening.
Filtration
Filtration is the largest application area for our steel meshes. Today’s advanced filter meshes and mesh combinations are the result of intensive research and countless implementations in the most diverse applications. Optimal filtration results must take into account a whole range of different factors.
Filter meshes
BOPP manufactures a comprehensive range of medium, fine and ultrafine filter meshes and stainless steel filters. These are produced in cleanroom and air conditioned situations to the highest reproducible levels of quality using state of the art weaving machines. Sintered products are increasingly specified to meet today’s challenging applications. These call for multiple layers of mesh produced using heat and pressure to form filter laminates.
Properties of our filter meshes
General properties of BOPP products developed for filtration applications
- Raw materials to the highest global standards
- Extremely precise aperture size distribution
- Uniform surfaces for improved processes and cleaning
- Advanced resistance to abrasion, no particle detachment
- High quality filtration results achieved by professional manufacturing
Requirements
The key considerations to meet challenges in the filtration process are:
- Material specifications
- Operational loadings – mechanical, thermal, chemical
- Pressure ratios
- Flow rates
- Mass, dimension, shape
- Fitting situation
- Compliance with standards
Sieving
In order to address the challenges presented by the field of sieving and sizing, we have created our own BOPP SI portfolio of products. BOPP sieving meshes guarantee the highest levels of precision and are recognised worldwide for their special properties.
Test sieves
Particle size distribution impacts upon the quality and characteristics of individual solids. A consistent grain size distribution guarantees consistent quality for the end product.
- Our complete range of test sieves meets the demands of ISO 3310-1 standard
- On request we deliver test sieve meshes complete with test certificate and aperture size certificate
Improved process results
Steel sieving meshes offer a range of advantages over alternative materials.
- Greater precision
- Improved efficiency
- Greater throughput
- Reduced downtime
- Improved economy
Stretching services
For high value sieving meshes, professional handling is as important as the mesh itself. This is why many of our customers entrust us with frame tensioning.
- Tensioning of all shapes up to 2600mm in size
- Retensioning and treatment of existing frames
Screen printing
BOPP SD is the name behind a comprehensive portfolio of stainless steel meshes developed specifically for screen printing applications. Precision wire, much of which is produced by BOPP, is woven on state of the art weaving machines in dust-free, air conditioned halls by experienced weavers to produce premium quality screen printing meshes designed to meet the highest demands in technical screen printing.
