When super-hard, nano-structured or temperature-resistant coatings
are needed, PVD and PACVD coatings and equipment from HEF USA
are thesolution.  Reliable, environmentally-friendly and versatile,
our advanced thin film coating technology represents a major
development in surface engineering.  PVD coating, and PACVD thin film
coating systems are ideal for a broad range of components used in
aerospace, automotive valve train, punching and cutting and forming
tools, plastics and rubber molding, hydraulic and medical devices,
and auto racing. 

HEF USA is the world leader in the development and customization of
high-performance thin film coating for ferrous metals, copper, titanium and
aluminum alloys, silicon, polymers, glass, composites, carbides and ceramics. 
We provide a turnkey solution that includes equipment design, manufacture
and installation, consultation regarding coating chemistries based on
performance requirements, and a broad range of standard and composition
(tailored) coatings.  We also supply PVD coating, and PACVD
coatings for facilities who already apply these technologies. 

Industrial Field Result: Aluminum Die Casting (13%Si, DieVar)
Encountered Problems: Aluminum transfer (soldering) and wear

• Nitrided: 14,000 parts
• TiAlN: 15,000 parts
• SD: 25,000 parts

HEF thin film coating systems improve performance, add value,
and solve critical challenges with friction and adhesion.  Here are
some specific advantages of HEF thin film coating options:

• Low friction coefficient, under high and low temperature conditions,
  with and without humidity
• High resistance to wear, abrasion, erosion and adhesion 
• Excellent aesthetics – an HEF thin film coating can impart a metallic
  appearance on polymers and glass, or produce a hard film.
• Optical properties enhancement – an HEF thin film coating
  provides filtering, reflectivity, or non-reflectivity
• Electrical properties - our thin film coating technologies provide
  conductivity, or electromagnetic shielding
• Material flexibility – an HEF thin film coating can allow manufacturers
  to specify less costly material with no compromise of end-use performance.
  (Example: An OEM lowered product weight by changing from steel to
  aluminum that was processed with an HEF thin film coating.)
• Higher load carrying capacity - with fewer lubricant additions,
  and less erosion – particularly for components, such as  
  turbine blades and propellers
• Reduced adhesive wear for titanium and other specialty metals
• Predictable, preferential release management for molding operations
• Reduced cycle times (for example, by accelerating ejection,
  and reducing maintenance, in plastic syringe manufacturing)
• Wear resistance, and prevention of sticking,
  for ferrous cold forming operations
• Wear resistance, and preventing of soldering,
  in aluminum casting operations
• Hard chromium replacement for many performance
  (non-decorative) applications

HEF thin film coating technologies are an intelligent, "green" alternative
for achieving complex performance objectives at reasonable cost.
