In the weaving process of fabrics, the shuttle clamp plays a key role in high-speed reciprocating transmission of weft yarns. It not only has to withstand a linear speed of 30m/s, 7-8 times/s of high-speed reciprocating motion, but also has to withstand motion impact. On the other hand, during long-term use, the shuttle clamp component is not allowed to affect the photoelectric detection system’s broken end detection due to its surface wear and whitening. Therefore, this component places extremely strict requirements on the mechanical strength and impact resistance of the material.

Usually, shuttle clamps are composed of a metal or plastic housing and a metal holder. As an ideal alternative to metal materials, using high-performance PEEK modified material solutions, the injection-molded projectile loom shuttle casing can reduce 80% of the weight while meeting component performance requirements, and extend the service life of the product. 1 to 2 times. In addition, compared with metal processing, injection molding can also significantly improve production efficiency and reduce the cost of secondary processing. Comprehensive comparison with the use of metal materials, high-performance PEEK modified material solutions can help customers save 30% of the total cost.

It is important to note that due to its inherent high temperature characteristics, PEEK modified materials need to be processed at a temperature of 360-400°C, which poses a challenge to the injection molding process and also places higher requirements on the high temperature resistance of the injection mold, mold temperature, and injection pressure and clamping force of the injection molding machine. Generally, it is recommended to configure an injection molding machine with a clamping force of more than 100t and a matching mold heating device.
