TWITTER Bike carbon fiber frame EPS technology

Ethyl Poly Styrene

The mandrel made of a thermoplastic material made of polystyrene compound conforming to the inner diameter of the frame is used as the basis for the production of the frame. If the stability of the overall quality of the frame can be enhanced, the internal wrinkles are prevented to increase the rigidity. In the market's pursuit of a highly rigid ultra-light frame, this technology can greatly extend the life of the frame and improve its safety. In the production process, the carbon fiber layer is coated on the EPS, and the mandrel is pulled out after being stabilized by molding. If the technology of TPM (thermoplastic layer technology) can be further combined, the ultra-light frame can be maximized. Good security effect.

1. Strong carbon fiber shell, durable frame, strong and light weight.

2.the finished frame has better hardness, toughness,strength to weight ratio, tightness and other qualities.

3.Significantly improve the stability and smoothness of the lamination

and joint between the inner cavity of the frame.

4 greatly reduce the excessive concentration of internal stress of the frame, the length of the finished frame life, stable quality

5.The finished frame has a smooth appearance.

Bicycle frame made of high quality carbon fiber T800/T900 Toray material, One-piece molding process, then processed by the world’s top T4/T6 heat treatment technology, the parts which have high requirement about the size will be precisely machining, finally all the parts will be assembled by manual and inspected strictly in high standard requirement to ensure each TWITTER is perfect.
