• Circuit Board Plating Company Uses NCT Rotary Turbine Vibrator for Improved Plating Consistency

  Problem

  A circuit board plating company was struggling with uneven plating results and trapped air bubbles during the electroplating process. These issues affected coating consistency and product quality, ultimately leading to increased rework and reduced efficiency.

  Situation

  To address the problem, the company turned to Martin Vibration Systems & Solutions for a solution that could enhance plating uniformity without adding complexity to their workflow. The answer came in the form of an NCT Rotary Turbine Pneumatic Vibrator mounted directly to the plating bar holding the circuit boards.

  The bar was positioned in UHMW V-blocks, which allowed it to remain securely in place while still transmitting vibration effectively. When activated, the oil-free, non-impacting vibrator produced high-frequency agitation that promoted movement in the electrolyte solution and helped dislodge trapped air. The system operated quietly and required minimal upkeep thanks to its durable materials and low-maintenance design.

  Solution

  The implementation of the NCT Rotary Turbine Vibrator allowed the company to:

  • Achieve more uniform plating across all board surfaces
  • Minimize air bubble formation during the plating process
  • Enhance electrolyte flow for improved material adhesion
  • Operate quietly and reliably with a non-impacting, oil-free vibrator
  • Maintain durability and simplicity using UHMW supports and low-maintenance components

  This straightforward upgrade significantly improved product quality and consistency — without the need for costly equipment overhauls or added labor.

• Emptying Big Bags Completely and ATEX Safely

  A chemical industry customer frequently emptied large bags up to 1,000 liters/2,000 kg. of the product into a container, but was unable to empty the bag thoroughly. This required workers to manipulate the bag manually to make sure all of the product had been emptied. Their objective was to provide a way to automate the process so that the bags would empty thoroughly without requiring manual labor. Also, the environment is classified ATEX zone 22 because of the potential for dust so it was required that the system not produce any sparks or discharge static electricity.

  The customer installed a MARTIN^® NCT™ Rotary Turbine Vibrator to a base assembly, allowing the contents of the bags to be thoroughly emptied. Also, the equipment was made according to ATEX Zone 22, eliminating the possibility of sparks or static discharge.

   

  

  

  

  
• Separating Boxes During the Production Process

  A customer who designs facilities for packaging industry had, as part of their new manufacturing line, a process wherein flat, unfolded boxes moving along a chute were picked up and moved by a robotic arm to the next step of the process. However, because the boxes would often stick together and become unlevel, the positioning of the box was not consistent and the robotic arm would frequently miss the top one.

  The customer purchased and installed a MARTIN^® NCT™ Pneumatic Turbine Vibrator under the chute. By vibrating the chute, they were able to reduce the friction between the boxes and level them into a consistent position. This allowed them to be more easily picked up by the robotic arm.

  

  

  

  
• Eliminating Build-Up At A Crushed Stone Quarry

  Problem

  A crushed-stone quarry in Tennessee was experiencing problems with material build-up in the feeder hopper under their sizing screens.

  Situation

  The material (size 1/4″ down to fines) would cling to the hopper walls and build up, eventually stopping material flow and shutting down the screening operation.

  Solution

  A MARTIN^® NCT™ Turbine Vibrator (NCT-108) was mounted on a channel on the end wall of the hopper. The vibrator was mounted on a 5″ x 48″ long channel and located 18″ from the bottom of the bin. After two weeks of operation, the customer reports no bin or feeder stoppages at this point. They are very pleased and we are now trying to help them solve other problems at their plant.
