Surface Finishing

We cater on a turnkey basis, offering plants of varied types with varied processes. Explore all the process we cater to below:

• Manufacturing of plants involves virtually all the branches of engineering and our vast experience make us the masters of the trade.
• The use of new materials and construction techniques make our plants highly resistant to corrosion, inherent to plating environments and therefore offer a significant advantage.
• Grauer and Weil plants range from Manual all the way to Fully Automatic PLC controlled plants.Plants can be configured in varies shapes based on the space available.

Plants we offer consists of:

• Rack Plant
  • These type of plants are used to electroplate large and complex components.
  • Since racks hold various components, it helps achieve uniform thickness distribution and reduce time and cost.

• Barrel Plant
  • These type of plants are used for plating a high volume of small components.
  • Barrel plating offers a cost-effective means of plating a high volume of small components.

• Rack and Barrel Plant
  • Growel offer a combination of barrel and rack plating in a single flexible plant.

• Continuous Plating Plant
  • Continuous plating systems are designed for high speed operations, more specifically for plating of strips, wires and tubes.
  • They comprise of a complex material handling system in keeping with the plating requirements, in an extremely dynamic state of movement.
• Rotomatic Plant
  
  • This is an ideal system for semi-automatic electroplating needs.
  • Components to be processed are hung on conductive hooks system which moves at settable conveyor speed, based on process timings.
  • Loading and unloading is at same point.
    
    
• Zinc Flake Coating
  
  
• Growel in collaboration with NFO Metal Coating Japan, is offering GEOMET based on DACROTIZED the rust preventive coating technology that has been perfected through 30 years of real world appreciation.
• The new chromium free coating technology is now being offered to the Indian industry in addition to DACROMET, which is already available with us.
• GEOMET is a water based coating technology that is completely free from Chromium.

Automation is greatly preferred in bulk plating operations, predominantly for the following reasons:

• Consistency
• Reduction in labour costs
• Elimination of human error
• Reduced operational costs
• Regulated inputs
• Effective control of production
• Versatility
• Traceability

Automation Features

Grauer and Weil plants come with an option of Galvcon 4.0. It is an optimised PC based software for process control. Our customers can set all process parameters such as bath sequence, bath dwelling time, drip times etc. by themselves.

GalvCon V4.0 is easy to use via touchscreen and consists of features like Load as you like for Rack and Barrel plants Automatic current, temperature control as per process requirement, Auto level and conductivity control of rinsing water, Production and event data recording, On line process monitoring, Event warning by SMS, Voice alarms, Barrel rotation sensing by current monitoring, Bar scanner for parts identification, Online monitoring of status of transport wagon, tanks and equipment and many more.

1. Description

Generally, it is seen in Passivation process that the bath is often contaminated by Zn and Fe build up. The Zn built up is due to Zn carryover from previous Zn coating and the Fe contamination is from the component surface. This usually leads to poor quality of coating. PASSIPURE is the solution for this very problem.

2. Application

PASSIPURE is an iron/zinc removal system used to remove both the contaminations from a Passivation bath by a single unit.

3. Benefits

• Ensures Consistent Quality.
• Reduces Bath Discard Frequency.
• Reduces Effluent Processing Cost.
• ROI of Less Than Two Years.

4. Technical data

We have two models available:

• PASSIPURE-BASIC – Manual
• PASSIPURE-PRIME - Automatic

Available both in manual and automatic models these unit help remove Iron and Zinc both from a single unit. This unit helps improves the quality of Zinc plating and reduces the bath discard frequency which directly reduces the effluent processing costs.

This unit helps in reduction of chromic acid consumption. Semi-automatic in operation, this unit can be offered with an evaporator for further concentration of Chromic acid. The unit reduces the bath discard frequency which directly reduces the effluent processing costs.

We offer following services for Operational Improvement of plants:
