DLC coating extends the life of the hook and reduces oil stains on sewing materials!
What is DLC?
DLC is an abbreviation for Diamond-Like Carbon, which is a hard coating that has properties similar to diamond and is mainly composed of hydrocarbon. By coating the surface of the material with a thin film of DLC, new properties such as hardness, lubricity, and wear resistance can be given.
Can be used stably for a long time!
DLC coating is applied to the conventional hook, and the surface hardness of the hook has been improved.
Wear resistance is improved, and wear and seizure of the shuttle and inner hook can be reduced, extending the service life and enabling long-term use.
Wear is reduced compared to conventional hooks. So stable seam quality can be obtained.
Reduction of oil stains!
Since the DLC coating has high self-lubricating properties, the hook lubrication could be minimized.
This hook can greatly reduce seizure even when used with a very small amount of oil.
The amount of hook oil can be minimized, reducing oil stains on sewing materials.

DLC hook
The LU-1500N Series / LU-2800 Series rotary hooks have DLC coating on the inner and outer hooks.
Features
Increased surface hardness!
High hardness coating improves wear resistance! Not only the service life of the hook is extended but also the seam quality is stabilized.
High self-lubricating properties!
Self-lubricating properties allow use with a very small amount of hook oil! As a result, oil stains on sewing materials are reduced.
