How many stations should I choose for the Phone Screen Polishing Machine?

Select the workstation based on the number of mobile phones the customer polishes. If the polishing quantity is more than 1,000 units/month, it is recommended to choose a grinder with more than 4 workstations. If the mobile phone repair shop polishes a small amount, you can choose a 2-workstation desktop mini grinder.

What are the differences between several models of Screen Polishing Machine?

Screen Polishing Machines differ in size, weight, and polishing capacity. (Single- and dual-station desktop models use pressure blocks to generate pressure, while the other blue floor-standing models use cylinders with adjustable downward pressure. A 2-station model can polish two phones at a time, a 4-station model can polish four phones at a time, an 8-station model can polish eight phones at a time, and a 16-station model can polish phones and tablets.) All models produce the same polishing effect.

What are the advantages of TBK Screen Polishing Machine compared with its competitors?

Our Screen Polishing Machine adopts PLC control, one-button start for simple operation, constant pressure valve accurately controls the downward pressure, the rotating part is equipped with a power assist system to extend the service life of the motor, low noise, built-in air compressor, built-in water tank, small size, light weight and low transportation cost.

What other accessories does the Screen Polishing Machine require?

Supporting equipment: dispensing machine, UV curing box, supporting consumables: polishing powder (50-80 mobile phones/500G), UV glue (25-30 mobile phones/piece), polishing blanket (recommended to replace after polishing 500 mobile phones), mold (dedicated for each model), Oleophobic Coating Liquid

What is the lifespan of a Screen Polishing Machine?

It uses a brushless, high-efficiency, low-noise motor with a long service life, generally 3-10 years.

How often should the sanding blanket be replaced?

The main component of the sanding blanket is wool, which is a consumable item. It is recommended to replace the sanding blanket after sanding 500-1000 mobile phones or every month. If the machine is not used for a long time, clean the sanding blanket, chassis and water tank, and store them after drying.

How to ensure that the phone does not get wet during polishing

Before polishing, check whether the waterproof glue is evenly applied. Use a UV curing box to enhance the curing effect of the waterproof glue. Check whether the phone has been disassembled. A disassembled phone is not suitable for polishing.

What should I do if the polishing effect is not good?

1. Continue sanding. Phones with deep scratches will take longer. 2. Replace the sanding blanket. 3. Increase the concentration of sanding powder. 4. Check the pressure.

What is the problem with the loud machine noise?

Check whether the training wheels are intact and whether the water mill is placed level.

What should I do if the machine has after-sales problems?

The machine has a one-year free warranty (excluding consumables: rollers, wool blankets, and water pumps), lifetime maintenance, and overseas after-sales service provides accessories and professional replacement and repair videos.
