ChatGPT 说:
We mainly use 3K resin prepreg bi-directional carbon fiber fabric, but 1K, 6K, and unidirectional options are also available. Material grades include T300, T700, T800, and M-series fibers for varying strength and performance needs.
Plain/twill weave with glossy/matte clear coating. And also we have unidirectional fabric without any weave surface. In additional, we have forged carbon fiber texture weave. You can choose what you want and let us know.
We need 3 details: 1. step/stp/x_t format drawing file; 2. quantity; 3. surface requirement.
Mold time 25-30 days; and sample time 7-10 days;
Yes, we can. But we need samples to scan the dimension or you can provide very detailed dimension to us. We can draft drawing file with surcharge.
Alizn offers moulds that cover almost all standard models of carbon fiber tubes available on the market. If the specific model you need is not available, we can customize a mould first, and then proceed with product manufacturing based on your specifications.
Aluminium mold, steel mold, fiberglass mold and carbon fiber mold, steel mold with high precision since it is hard and produced by machining, so steel mold is the best option. For inside mold, normally with metal mold, or airbag core or silcone core.
Our carbon fiber products can be manufactured according to customer requirements using techniques such as autoclave moulding, filament winding, pultrusion, and rolling moulding to ensure high strength, lightweight structure, and excellent surface quality.
