Surface Finishes

  • Anodizing: creates a corrosion-resistant oxide coating with improved hardness and durability.
  • Electropolishing: produces a smooth, reflective finish free from micro-burrs and contaminants.
  • Nickel Plating: enhances surface wear resistance and provides uniform protection against oxidation.
  • Passivation: strengthens stainless steel’s natural resistance by removing embedded impurities and free iron.

What makes front press blocks essential in precision assembly systems?
They maintain exact load paths and prevent misalignment or deflection, ensuring uniform pressure distribution and extending the system's life.
Can front press blocks operate effectively under thermal cycling?
Yes. Heat-treated tool steel or Inconel variants sustain stable performance across repetitive temperature changes.
Are flatness and hardness tested during inspection?
Every block undergoes hardness verification and CMM-based flatness measurement before approval for service use.
Can custom coatings or thickness levels be applied?
Yes. Coating types and thicknesses are adjustable to meet environmental or frictional performance requirements.
What documentation accompanies each production lot?
Complete traceability records, FAI reports, and material certifications are supplied for all production quantities.
