Drawing-based custom stainless steel filter assemblies, filter elements and housings built around your media, flow rate, pressure, temperature, installation space and OEM equipment requirements.
Custom Manufacturing
As a custom filter manufacturer, SINFT builds stainless steel filter assemblies when the filter is not just a replaceable cartridge, but part of a larger equipment structure. The element may need a special end cap, flange, threaded connection, support tube, handle, welded frame, multi-layer media stack, or exact dimensional match to an existing housing.
SINFT works from drawings, old samples, housing dimensions, and operating conditions to confirm whether the design can be manufactured, cleaned, tested, and repeated across production batches.
Our focus is not only making the first piece. We review each custom filter element or housing assembly for long-term consistency, pressure stability, weld reliability, media compatibility, and practical maintenance in the customer's working environment.
OD, ID, length, connection type, flange size, end cap profile, handle, support tube, and sealing position can be matched to your housing.
Pleated mesh, sintered mesh, sintered fiber felt, perforated tube, wedge wire, and combined structures selected by media and filtration target.
Designed around flow rate, pressure, temperature, viscosity, corrosion risk, cleaning method, particle load, and service-life expectation.
Samples, dimensional checks, weld inspection, passivation, and batch documentation help keep the approved design consistent over time.
Custom Options
A custom filter assembly usually combines several filter media, structural parts, and connection details. The final design is confirmed from your drawing, sample and operating data.
How We Work
For custom filters, the early technical review matters. We confirm the filtration target, structural risk, weld method, material compatibility, and whether the custom filter design can be produced consistently in future batches.
Start Technical Review arrow_forwardProvide drawings, photos, old sample dimensions, media, flow rate, pressure, temperature, and target filtration rating.
We review material, media structure, welding method, pressure stability, cleaning method, and production consistency.
Standard custom samples can usually be prepared in 48-72 hours after drawing confirmation. Complex structures may need 5-7 working days.
After sample approval, we control key dimensions, weld quality, surface finish, packaging, and documentation for repeat orders.

FAQ
Please send drawings, photos, OD, ID, length, connection type, seal position, media, flow rate, pressure, temperature, working fluid, filtration rating, and quantity. If you only have an old sample, photos and measured dimensions can start the review.
Yes. Prototype orders are supported. Standard custom samples usually take 48-72 hours after drawing confirmation, while complex assemblies may require additional review and production time.
Yes. Matching existing housings is a common request. We review dimensions, end cap profile, sealing area, insertion depth, removal method, and flow direction before confirming the design.
Yes. Our technical team can provide 24-hour online guidance based on your working conditions, helping select media, material, connection type, and cleaning method before quotation.
