Wedge Wire Screen Manufacturing Full Process Guide

—BTOSLOT Expert Insight into Precision Filtration Technology

Introduction: What is Wedge Wire Screen?

Wedge wire screen, also known as profile wire or V-wire, is a critical filtration and separation component used across a broad range of industries. With its unique triangular cross-section, wedge wire allows for precise slot openings, non-clogging filtration, and exceptional structural strength. At BTOSLOT, we specialize in custom manufacturing of wedge wire screens for water treatment, mining, food processing, petrochemical, sugar, paper, and architectural applications.

1. Raw Material Selection: Alloys Matter

The foundation of a high-performance wedge wire screen lies in its material composition. Depending on application environments—such as high corrosion, high temperature, or food-grade hygiene—different alloys are selected:

Common Alloys We Use at BTOSLOT:

• Stainless Steel (SS304, SS316, SS316L, SS430, SS201)

• Duplex Stainless Steel (2205)

• Carbon Steel

• Nickel Alloys (Hastelloy, Monel 400, Inconel)

• Titanium and Aluminum (for special environments)

Material selection takes into account mechanical strength, corrosion resistance, thermal endurance, and cost-efficiency.

2. Precision Shaping of the Wedge Wire

The manufacturing process begins by rolling or drawing the metal into the signature wedge shape. The wire features a narrow nose and wider base, enabling effective filtration while allowing fluids or gases to pass freely.

Key parameters include:

• Nose radius

• Wire width

• Wire height

• Surface finish

At BTOSLOT, advanced shaping technology ensures tight tolerances and smooth edges for consistent filtration accuracy.

3. Slot Design and Wire Spacing

The space between two wedge wires defines the slot size, which determines the filtration precision. Slots can range from 0.05mm to 10mm depending on application.

Precision matters because:

• Inconsistent spacing leads to uneven filtration

• Too wide = poor filtration

• Too narrow = clogging risks

We use automated welding and vision systems to verify spacing consistency across the entire screen surface.

4. Welding Onto Support Structures

Wedge wires are resistance welded or TIG welded onto support profiles, which can be:

• Support Rods (Round, Triangular, or Flat)

• Support Rings

• Frames or Tubular Drums

The final screen form depends on the application:

• Flat Panels

• Cylindrical Screens (Johnson type)

• Conical Baskets

• Sieve Bends or Curved Screens

• Trommel Drums

BTOSLOT custom-builds support structures to ensure strength, flow capacity, and durability.

5. Custom Forming and Fabrication

Depending on end use, wedge wire screens are cut, rolled, flanged, or machined into final configurations. Examples:

• Sugar mills → rotating drums

• Water treatment → filter nozzles

• Mining → sieve bend screens

• Architecture → decorative panels

We ensure all custom shapes meet exact customer specifications and pass dimensional quality checks.

6. Surface Treatment and Finish

The surface finish can significantly affect both performance and aesthetics. Especially in architectural or hygienic applications, surface smoothness, reflectivity, and cleanliness matter.

BTOSLOT offers:

• Electropolishing

• Pickling and passivation

• Mechanical polishing

• Sandblasting (on request)

7. Final Quality Control and Inspection

At BTOSLOT, quality assurance is built into every stage. Final inspection includes:

• Slot tolerance measurement (±0.01mm possible)

• Surface flatness and uniformity check

• Welding integrity test

• Corrosion resistance tests

• Dimensional verification using optical systems

We maintain ISO-certified quality systems and provide full inspection reports upon request.

8. Packaging and Delivery

All wedge wire screens are carefully packaged to prevent damage during transportation. Options include:

• Wooden boxes or pallets

• PE films for moisture protection

• Steel frames for large cylindrical units

We support international shipping and provide technical installation guidance when needed.
