A warp knitting machine is a compact system integrating components like needles, sinkers, guide bars, and others to optimize performance and efficiency. All parts need to have high strength and wear resistance for the durability necessary for the warp knitting machine to operate for nearly 24 hours a day at high speed. Each needle will be performing several million knitting actions that require high precision. These components must be highly polished and precisely manufactured to ensure the product quality of warp knitted fabrics.
Stamping die manufacturing
Since needle precision directly impacts the final quality of knit products, we pay serious attention to developing stamping dies with higher accuracy to ensure needle quality.
Affar employs highly qualified stamping die designers and a die manufacturing workshop. We are especially proud of our stamping dies made by low-speed wire cutter with an accuracy within ±1μm.
Processed semi-finished needles will be polished to eliminate any excess metal burrs and sharp edges through the use of different polishing machines. If you require higher quality standards regarding surface smoothness, we can process your needles with chemical treatment for deburring.
Products like latch needles, sinkers, and guide needles are units of individual needles casted into a block. We are capable of die casting needle block with tin or plastic to meet different requirements on the needle bar .
All needles are strictly examined for straightness and accuracy using profile projectors before being placed in our storage warehouse. All the needle bars are calibrated and assembled for a better consistency to ensure all Affar products maintain an excellent, reliable performance.
