Requirements A leading automotive suspension manufacturer asked GBM INDUSTRIES  to develop a system that would reduce Hydrogen Embrittlement from parts after plating. To win the bid GBM INDUSTRIES had to provide a solution with a consistently precise material handling system and tight part temperature uniformity. With floor space being a premium a small footprint was imperative. 

Solution – GBM  INDUSTRIES Hydrogen Embrittlement Oven

 The result was an electric heated close loop system whereas the product is loaded and unloaded at the same spot. 

The main features of this system included: 

  • Fully automated square loop indexing conveyor system
  • A two position preheat section 
  • Three position soak zone 
  • Vertical lift doors to prevent heat loss 
  • Single pass thru ambient air cooling section

Results GBM INDUSTRIES designed and delivered a hydrogen embrittlement oven that maximised output and reduced labour costs for our customer.  

Summary

 The Hydrogen Embrittlement Relief Oven is available in either a Batch Oven or Continuous Conveyor configuration. In the continuous process, batched parts travel through the heating chamber in individual bucket carriers so that different type parts remain separated. Pneumatic vibration is incorporated at the off load station to ensure all parts are discharged from the bucket.

Features:

  • Recirculation fans with high efficiency motors to reduce energy consumption.
  • Recirculation ductwork designs provide precise airflow to specific areas of the product resulting in smaller footprint ovens thus reducing utility and factory space costs.
  • High-efficiency (gas or electric) heat sources to reduce energy costs.
  • Robust structural oven frames and component supports.
  • Application specific insulation materials are selected to provide optimum insulating characteristics and long term energy savings.
  • Design considerations for easy access to process areas and oven components.
  • Private labelled and purchased components meet UL, UR, and CE standards.
  • Programmable controllers with HMI (Human Machine Interface) displays allow for user friendly operation and machine diagnostics.
  • NEMA style control panels.
  • Factory tested to ensure on time delivery and field start up.
  • 24/7 factory direct technical service and spare parts group.
