1. Different technical levels
TFS is the abbreviation of imitation hydraulic forming, and its English name is: Techo Forming System. It adopts 3D three-dimensional special molding technology and is a unique patented technology of Merida. It is manufactured using a relatively simple process imitating HFS.
The HFS frame is a truly technical Merida frame. HFS is the abbreviation of Hydraulic Horming System, which uses special Hydraulic Horming System hydraulic forming technology.
2. Different weights
Since the TFS frame is a simplified version of HFS, the HFS frame is lighter in weight compared to the TFS frame, such as Merida 6066 prolite aluminum alloy Frame 18 The frame is about 1.4kg, but it maintains ultra-high rigidity and strength.
3. Different costs
Because the hydroforming technology used in the HFS frame can make the tube wall thinner, thereby reducing weight and improving strength, but it also requires higher requirements. , the processing equipment is expensive, the scrap rate is high, and the cost remains high.
Relatively speaking, the technical requirements of the TFS frame are not as high as those of the HFS frame, so the cost is lower than that of the HFS frame. TFS frames are commonly used on Merida’s Challenger series. Common sizes are 16 and 18.
