Meaning
Industrial surface modifications improve the durability of sliding components in high-precision manufacturing equipment. Applying a diamond like carbon sleeve coating to the moving steel slides of an injection moulding machine or tool minimizes friction and metal-on-metal contact. This amorphous carbon layer provides extreme hardness coupled with a very low coefficient of friction, protecting the underlying substrate from both chemical attack and mechanical stress during continuous operation.
Friction Reduction
Sliding elements in mould tooling often operate without external lubrication to avoid contaminating the moulded plastic. Implementing a diamond like carbon sleeve coating allows ejector pins and sleeves to glide smoothly against the core plate. This dry running capability reduces the risk of grease transfer to the finished product.
Wear Prevention
High-speed cycling creates intense localized heat and abrasive action between mating steel surfaces. A diamond like carbon sleeve coating acts as a barrier that resists galling and adhesive wear under high clamping forces. This protection is effective in close-tolerance micro-moulding applications where even micrometre-scale wear ruins the part.
Tooling Longevity
Maintenance schedules for complex multi-cavity moulds depend on the wear rate of their moving parts. With a diamond like carbon sleeve coating, the service life of guiding sleeves is extended.
