Automated Deburring Solutions
for Zinc Alloy Castings

Zinc alloy melts at low temperature, chips easily and hides pores. Dingzhu solves the 6 hardest pain points in robotic deburring and polishing of Zamak die castings — with gentle force control, laser scanning and anti-clog abrasives.

The Dingzhu Approach: Perception + Force, Dual Guarantee

Scan first to locate flash and measure stock, correct the path, then apply capped compliant force. Zinc castings come out clean, cool and dimensionally true.

01

Sense & Locate

Laser / vision scanning pinpoints gate flash and measures actual stock

02

Adaptive Trajectory

Path corrected to flash zones only — surrounding surface untouched

03

Capped Force Grind

Compliant force held within a zinc-safe window with active cooling

04

Clean, True Output

Flash-free, pore-closed, in-tolerance zinc parts ready for plating

  • PERCEPTION GUIDE

Which Sensing Method to Choose?

Three mainstream perception approaches. For zinc flash and pore-prone surfaces, we prioritize laser line scanning.

3D Laser Line Scanning

Scans the casting to locate gate flash and measure stock precisely, correcting the path before contact. Best for flash removal and shallow controlled removal.

  • Principle: laser profile → 3D contour → trajectory correction

  • Accuracy: ±0.05mm

  • Best for: flash location, shallow removal

Force-Probing Locating

A force sensor lightly touches the part to probe position and compensate. Low cost, but limited to simpler geometry.

  • Principle: physical touch probe detects position

  • Cost: Low

  • Best for: simple shapes, distinct features

Vision Photography Positioning

An industrial camera captures the whole-part outline to compute and correct clamping deviation.

  • Principle: photograph outline → correct clamping offset

  • Cost: Moderate

  • Best for: lower-precision positioning needs

  • ABRASIVE BELT SELECTION

Don’t Let a Few-Dollar Belt Ruin a Zinc Casting

Zinc is soft and pore-prone — the belt must cut gently without loading or digging. Three rules we apply.

Soft-Feel Anti-Clog Belts

Rule 1 — Belt type: For zinc we favor 423A soft-feel belts with an anti-clog coating that resists zinc loading, giving a uniform, pore-closed finish without digging into the surface.

Best for: zinc, copper, soft metals

Soft Backing & Seamless Joint

Rule 2 & 3: J-grade soft backing + seamless joint conforms to thin-wall zinc without beat-marks; shallow, multi-step removal avoids opening pores in one aggressive pass.

Best for: thin walls, no trace

Belt 726A for Cells

726A: tear-resistant soft cloth, ideal for robotic grinding cells, works on steel / stainless / copper / aluminum / zinc. Pairs with non-woven pads for uniform pre-treatment.

Best for: automated grinding cells
