APPLICTION OF ABRASIVE FILAMENTS
DAMI abrasive nylon filaments are mainly used to make polishing and deburring brushes.We use hig-quality nylon raw materials integrated with diamond,silicon carbide,aluminum oxide and ceramic to make abrasive filaments,so brushes made by abrasive filaments have both the characters of orginary brushes and cleaning function,which are beyond the industrial application of ordinary brushes.
DAMI abrasive filaments have good heat stability,durable in high temperature,acid-alkali resistance,as well as low water absorption,can keep good stiffness and toughness in dry and wet working condition,which make it widely used in many industrial lines.
APPLICATION SCOPE:
- Surface processing of cooper or aluminum rolls
- Deburring for automobile hug,gear,and engine parts.
- Precision processing for compressor parts of refrigerator and air-conditioner
- Deburring after mechanical treatment and chamfering
- Polishing for the surface of die casting
- Deburring for the inner wall of hole
- Polishing for the surface before electroplating and coating
- Cleaning for militar y weapon
- Cleaning and polishing for PCB circuit board
- Textile sueding process and jeans cloth discoloration
- Polishing for stone antique surface,furniture,etc
- Polishing brushas tools of angle grinding,pneumatic tools,etc.

Application:Abrasive brush for auto hub
This type of abrasive filaments are suitable to make disc brush for polishing auto hub,which popularly used in auto hub manufacturers abroad many years but still almost blanket in domestic market.With the international purchasing for made-in-china auto hub,and the technical improvement in domestic manufacturers,most of them begin to use this brush.The characteristic of the brush filaments lies in big diameter of 1.6mm,which help to increase the stiffness of the filaments,and extend the working life.At current, the working target from customers is polishing four thoudsand auto hubs each brush,our filaments have already passed the test.
About Abrasive Filament
DAMI abrasive filaments are produced by loading abrasive grits such as silicon carbide (SIC) or aluminum oxide (AO), Diamond evenly into high-quality nylon and extruding the mixture into filaments.
DAMI abrasive filaments have superior stiffness, good flexibility, and great elasticity. Brushes made with DAMI abrasive filaments are highly efficient in grinding, finishing, polishing, and deburring in different industries and for different surfaces e.g. curved, concave, convex surfaces or insides of pipes without damaging the dimensions and fineness of the workpiece.
Silicon Carbide (SIC)
Common used abrasive grit is silicon carbide aka SIC grit, which is produced in a resistance type electric furnace with petroleum coke, quartz sand and other materials. SIC is an extremely hard black insoluble crystalline substance. It is used as an abrasive and heat-refractory material and in single crystals as semiconductors, especially in high-temperature applications. Its micro hardness is HV3100-3280, stiffness and hardness is higher than White Alumina. SIC abrasive filament can be widely used to produce industrial brushes for steel, textile, PCB cleaning, stone polishing, and other grinding applications.
PROPERTY COMPARISON OF GRIT
- Vickers hardness (HV): DM > SIC > AO
- Cutting force: DM > SIC > AO
- Price: DM > SIC > AO
PROPERTY COMPARISON OF NYLONS
Bend recovery: PA6<PA610<PA612
Water absorption: PA612<PA610<<PA6
Durability:PA6<PA66<PA610<PA612
THE BEST ONE IS THE MOST SUITABLE ONE
The most popular abrasive filaments are SIC and AO filaments. SIC abrasive is generally the best choice for the most of the applications. AO is suitable for precision polishing and soft surface. Basically, every industry has its own common-used abrasive filament. For detailed questions, please do not hesitate to contact us for consulting. It would be more helpful, if you can send us some samples for analyzing.
