GNEE RAIL's in-house manufacturing process for dog spikes encompasses multiple stages, from raw material preparation to finishing and inspection.
Raw Material Preparation
The first step in GNEE's dog spike manufacturing process is raw material preparation. GNEE RAIL primarily uses carbon steel, cast iron, and stainless steel as raw materials for dog spike production. These materials are carefully selected by GNEE's professional technical team to meet the specific requirements of dog spikes.
Heating and Forging
The next phase in GNEE's dog spike manufacturing process involves heating and forging. The raw materials are heated to a specific temperature to achieve malleability. The heated material is then placed in forging presses to be shaped into the required form. The forging process applies pressure to the heated metal, compressing and forming it into the desired shape. This process enhances the strength and durability of the dog spikes.
Finishing and Inspection
After forging, GNEE performs finishing and inspection on the dog spikes. The finishing process includes trimming excess material, cleaning, and polishing the spikes. Subsequently, we conduct thorough inspections to identify any defects that may have occurred during production. GNEE maintains a comprehensive quality inspection system for railway spikes, ensuring each spike meets all specified requirements through rigorous testing.
GNEE RAIL offers cut track spikes in various specifications. We also offer screw spikes. If you require more detailed product information, please contact us.
