Industrial Screen Scratch Repair Solution

High-Volume Polishing Ecosystem for Grade-A Refurbishment

1. Standardized Factory Workflow: The 5-Step Cycle

A strictly defined industrial process ensures consistent quality and safety for every device. This workflow transforms a scratched phone into a "Grade A" refurbished unit.

Step 1: Automated Waterproof Sealing

Equipment: TBK-983B Glue Dispensing Machine Before any water touches the device, it must be sealed. Operators place the phone into the dispenser, which follows a pre-programmed path to apply UV waterproof adhesive with 0.02mm precision. This creates a perfect barrier around sensitive areas like the receiver mesh, charging port, and buttons, preventing liquid ingress during polishing.

Step 2: Batch Curing & Hardening

Equipment: TBK-905A UV Curing Box Once sealed, devices are placed in batches into the TBK-905A. Its 200W high-power UV lamps cure the adhesive rapidly. This fast solidification ensures the waterproof seal is robust and fully bonded, ready to withstand the friction and moisture of the polishing chamber immediately.

Step 3: Precision Loading & Fixturing

Tooling: 3D Precision Molds Devices (or standalone screens) are securely mounted into brand-specific 3D Polishing Molds. These molds fit perfectly into the TBK-938's multi-station slots (holding up to 16 units). The precision fit ensures the glass surface is perfectly leveled for even grinding, while protecting the bezel from accidental damage.

Step 4: Intelligent Water-Injection Polishing

Equipment: TBK-938 Series Polishing Machine The core restoration phase. The machine circulates a mixture of water and Cerium Oxide powder, while the Wool Pad applies constant, PLC-controlled pressure. This wet-sanding process gently removes the microscopic top layer of the glass, physically erasing scratches without generating heat that could damage the LCD.

Step 5: Surface Restoration & Finishing

Consumable: TBK Oleophobic Coating After polishing, the screen is hydrophilic (water-absorbing). The final step is to clean the device and apply a new layer of Oleophobic Coating. This restores the screen's original smooth touch, water resistance, and anti-fingerprint properties, returning it to a "factory-new" tactile state.

2. The Production Engine: TBK-938 Series Polishing Machine

Designed for scalability. Choose the station capacity that matches your factory's daily throughput.

Multi-Station Architecture (Scalability)

Flexible Capacity: The TBK-938 series offers a modular lineup to fit any production scale.
TBK-938 (8 Stations): The standard choice for mid-sized operations.
TBK-938-16 (16 Stations): The large-capacity factory unit. It can polish 16 screens simultaneously, maximizing output per man-hour.
Also available in 2-station (938M) and 4-station (938L) models.
Water-Injection Polishing: Uses a constant circulation of water and abrasive powder. This keeps the screen cool during grinding, preventing heat damage to the LCD/OLED while ensuring an effective yet uniform cut.

Intelligent Industrial Control (PLC System)

Customizable PLC Automation: Equipped with a high-performance PLC (Programmable Logic Controller) system. It allows operators to fully customize polishing time and operation parameters, ensuring the precise execution of complex polishing programs tailored to specific batch requirements.
Fully Adjustable Polishing Force: Unlike machines with limited fixed settings, the 938 series allows operators to fully customize the downward polishing pressure. You can fine-tune the force parameters based on the specific glass hardness and scratch depth, ensuring optimal material removal without damaging the screen structure.
Integrated Workstation: Features a built-in silent air pump and liquid circulation system, making it a self-contained unit that requires no external plumbing complex.

3. Automated Pre-Processing: Sealing & Curing

High-precision automation replaces manual labor to ensure 100% waterproofing reliability.

Step 1 Equipment: TBK-983B Glue Dispensing Machine

0.02mm Precision for Waterproofing
Programmable Path Control: Unlike inconsistent manual gluing, the TBK-983B allows you to program complex paths (lines, arcs, circles) to seal receiver meshes and button gaps effectively.
High Precision: With 0.02mm accuracy and an advanced pressure valve, it ensures uniform glue output without leakage or dripping. This guarantees every phone is watertight before entering the polishing bath.
Versatility: Compatible with UV glue, sealing multiple devices rapidly to keep up with the polishing line's throughput.

Step 2 Equipment: TBK-905A UV Curing Box

200W High-Power Curing
Industrial Batch Processing: Features a spacious 230x290mm work area capable of holding multiple phones at once.
Rapid Solidification: Utilizing 96 high-intensity UV beads (200W), it cures the waterproofing adhesive quickly, ensuring the seal is hardened and ready for polishing immediately.
