Overview

A sugar mesh is the perforated lining screen fitted inside batch and continuous sugar centrifugals; it lets molasses and syrup pass while retaining the crystal mass, so slot width, hole geometry and open area directly set yield and throughput. Sugar mesh etching service covers the full route from drawing review and rapid samples through tool-free revisions to sustained volume production of these screens, using photochemical machining to form clean slots and holes in 304/316L or duplex stainless sheet without the die lead time of punching.

As a service, the workflow is built around supply rather than one-off parts: engineers convert the centrifuge basket drawing into artwork, cut first-article screens on film only, and hold the approved pattern for repeat orders and spare-screen programs. Because the pattern is imaged photochemically, a worn or upgraded screen can be re-cut from the same digital master with no new hard tooling, and panels can be supplied flat, rolled, seam-welded or framed to the basket. Sugar mesh etching service therefore supports both prototype validation and steady seasonal supply at 0.3–2.0 mm stock with conical or slotted perforations.

Parameter Window

• Available Materials: 304/316L stainless steel, duplex stainless steel, nickel
• Material Thickness Range: 0.3–2.0 mm
• Tolerance: ±0.05 mm on slot/hole, ±0.10 mm on developed panel outline
• Minimum Feature: 0.40 mm round hole, 0.30 mm slot, conical/countersunk perforation
• Surface Options: electropolish, passivation, deburring, edge hemming and frame welding, bead blasting
• Compliance: ISO 9001 process control, RoHS/REACH material traceability

Manufacturing Process / Workflow (8 Steps)

1. Artwork & DFM Review — Convert the basket drawing into vector artwork and check slot width, pitch, margin and rolling/weld allowance.
2. Material Selection — Choose 304/316L or duplex stainless steel in the right temper and confirm flatness, surface grade and abrasion resistance.
3. Cleaning & Lamination — Degrease the thicker sheet and laminate dry-film photoresist on both faces with matched heat and pressure.
4. UV Exposure — Expose slot and hole artwork through registered film, sharing datum marks across multiple screens for consistent pitch after rolling.
5. Development — Wash out unexposed resist to open the pattern, then inspect the narrowest slots for residue before etching.
6. Controlled Etching — Spray chemistry matched to the alloy, and double-side etch where a tapered drainage hole is specified.
7. Stripping & Forming — Remove resist, neutralize, then electropolish, deburr, and roll, seam-weld or frame the screen to the basket.
8. Inspection & Packaging — Verify hole pattern, slot width and open area against the approved first article, then log the digital master for repeat supply.

Core Advantages

1. No hard tooling: Samples and new hole patterns are cut from film, so trials and seasonal spare screens avoid die lead time and cost.
2. Burr-free apertures: Clean, smooth hole walls do not snag or shear sugar crystals, and need no secondary deburring.
3. Conical perforations: Double-side etching makes wide-entry, narrow-exit holes that drain freely and resist blinding by massecuite.
4. Repeatable master: The approved digital artwork is archived, so replacement and upgraded screens repeat identically across seasons.
5. Thick-stock capability: 0.3–2.0 mm stainless and duplex sheet hold slot geometry and stiffness under centrifugal load.
6. Supply flexibility: Flat, rolled, seam-welded or framed panels and spare-screen programs are all handled within one service.

Typical Applications

• Batch centrifugal screens: Perforated basket liners for batch white-sugar centrifugals.
• Continuous centrifugal liners: Slotted liners for continuous machines with high open area.
• Massecuite and molasses separation: Screens that retain crystals while draining mother liquor.
• Refinery filter screens: Perforated plates for syrup polishing and filtration.
• Spare and replacement screens: Re-cut screens held on the digital master for maintenance cycles.
• Screen upgrade programs: Existing mesh re-cut to a new open area without changing hard tooling.

Design Notes & Process Considerations

1. Slot orientation: Align slots with drainage and rotation direction; set slot width from crystal size so fines are retained without blinding.
2. Open area versus thickness: State open area and material thickness together, since a high open area on thick stock can weaken the basket.
3. Conical hole callout: Give inlet and outlet dimensions separately when double-side etching is used, not a single blanket tolerance.
4. Forming allowance: Mark seam-weld position and rolling allowance on the drawing, and require flatness and burr-free edges after forming.
5. Surface and corrosion: Name electropolish or passivation, since alkaline wash and abrasive massecuite govern crystal release and service life.
6. Spare program: Group screens with shared registration marks and store the digital master number so sugar mesh etching service can repeat orders exactly.
