SD300-WJS+3D & SP1300 – Precision Without Ejection. Edge Rounding Without Damage.

“If your surface prep fails, your paint will fail. Full stop.”

Manufacturing truth: Coating defects aren’t surface issues, they’re preparation failures.

From HVAC brackets to appliance trims, today’s thin aluminum and coated parts can’t be finished the old way.

• Paint peeling at burrs

• Scratches on anodized or film-covered parts

• Small parts flying off conveyors

"Surface defects aren’t cosmetic—they’re corrosive liabilities."

The Real Problems No One Wants to Talk About

Problem 1: Coating failure starts at the edge

Unrounded burrs at corners and flanges cause paint to thin, leading to adhesion failure and flaking—especially on HVAC, telecom, or appliance parts.

Problem 2: Scratches during finishing

Anodized panels or film-coated aluminum trim get damaged in traditional dry brushing systems, where abrasive misalignment or part vibration can scar finishes permanently.

Problem 3: Part instability

Small parts—60mm tabs, flanges, or rackmount brackets—eject from machines or jam on conveyors. The risk? Injury, downtime, lost precision.

JONSEN’s Solution – SD300-WJS+3D + SP1300

SD300-WJS+3D – Enclosed Wet Deburring Machine

• Disc brush system for complex edge rounding

• Wet processing eliminates heat, airborne particles, and oxide residue

Case Study – HVAC Manufacturer Reduces Rework and Part Loss

Issue:

• Coating defects on corners

• Scratches during polishing

• Small parts ejected from dry deburring system

Solution:

• Installed SD300-WJS+3D + SP1300

• Vacuum conveyor and dust-free wet process

• Film-safe brush control with edge radius tuning

Results after 30 days:

• Paint failure rate: ↓ 89%

• Scratches on panels: ↓ 95%

• Lost parts/ejected: virtually zero

• Labor saved: 2.5 hours/day

• First-pass yield: ↑ from 83% → 97.4%

Value Summary – Why This Setup Outperforms Traditional Lines

✅ Film-safe: no damage to anodized or laminated materials
✅ Edge radius control: meet coating spec with no rework
✅ Wet operation: safer, cleaner, more stable
✅ No ejection: small parts stay in place
✅ Compact & configurable: designed for cell or inline use
✅ Saves time & labor: fewer stations, faster output

“Every part finished right the first time is one less warranty call later.”

Take a Side – Is Your Finishing Process Working For or Against You?

Still using dry deburring on filmed aluminum panels?
Losing small parts to misfeeds or roller ejection?
Struggling to pass adhesion or scratch resistance testing?

You have two choices:
Keep patching defects…
Or start engineering quality into the surface.
