Let's go to Carbonal bike factory production line to have a look.
1.Material cutting and preparation, the first step of the production line, here we can see many carbon fiber cutting and stamping machines. Carbon fiber cutting is the key to achieving high quality laminate. Carbonal workers handle all original Toray T700 and T800 carbon fiber carefully, precisely control the laminate angle and thickness of each carbon fiber, and guarantees the consistency of products. It's an important part for building ligher and stabler product structure with less carbon fiber. Also have basalt material used on the rim braking surface for increased stopping performance and durability.
2.Pre-Preg and Layup, the thin, pliable sheets of carbon fiber impregnated with resin, so you can make any shapes as you want, high TG resin be used to make carbon bike rim is good enough at high temperature heating on wheels during braking.
Then the carbon prepreg is assembled around a pneumatic core that provides an out ward force on the rim during carbon curing, for other parts (same: small strips of carbon around a solid core inside a mold.
3.Molding. Before we get into the molding area, many steel molds on the side corner, a lots money invest here.
Many molding machines in the molding area, it is a little bit hot at this area even though has air conditioning system here,the carbon cured at high temperature in the molding machines (hot press molding,PC hydraulic molding machines with pressure temperature and time control).
4.Machinery Work. Work about bonding joints,drilling holes and checking the appearance of raw finish frame/rim.

6.Quality control and packing.
Quality control one by one before packing
Scan the barcode on every rim into the computer system, each rim details include date of order/production, rim finish, spoke holes, quality etc. can be tracked anytime if you input the barcode.
