HOW WE MANAGE THE PRODUCTION PROCESS TO MAKE SURE STABILITY & EFFICIENCY

Carbon composite is a super material, but also super naughty.
Without a good production process system, you will still not be able to get what you intend to.
We need still to control the possible variations during manufacturing.
Although we would equipped with more and more automatic process, especially for lamination,
This would be the future for normal and standard carbon rims.
For high end light weight and stiff carbon rims, the best would still be hand-made.

Here, we mainly show how we improve our hand-made works to improve and make sure the quality.

HOW WE PREPARE THE FABRICS FOR LAMINATION

“It’s known that the circumference of a 700c or 29″” rim is around 2 meters long.”
Many manufacturers are dividing it into two pieces, that is, one piece around 1 meters long.
Then connect the two pieces together to become a rim circle.
Many factories do this for many years already.
Indeed, there are some very unperceptible problems.
For example, maybe, you have the experience that during wheel building,
There are always some spots not flat, especially, the edge along the bead.
Or during riding, riders always feel a remarkable rolling-weight-unbalance, especially, at higher speed.
The reason actually is because the manufacturers are preparing the fabric at least two pieces, some even more.
“So there are too many “”knots”” .”
Where the knots accumulate together, making some position over-weight, and over-thick.

After founding out this secrets, now we only prepare the fabrics in complete piece only.
So there would be only one knot one layer.
And our engineer could do just the knot position to control the weight balance and flatness.

WAX CORE AND AUTOMATIC MOULDING SYSTEM

To improve the moulding work, indeed we developed three technologies to help our workers and improve our quality and stability.
One is our wax core technology.
This technology greatly improves our moulding-workers efficiency and accuracy.
They don’t needs to be haunted by the pain of how to correctly put the rims into the moulds.
This was a big issue before, and causes many quality problems actually.

With the wax core technology, we could also improve our mould designs.
This improvement saves workers’ a lot time in assembly & dis-assembly the moulds, after putting the rims into the moulds

The third, we developed an automatic system to help workers to move the heavy moulds into the heating and cooling equipment system.
This also savers workers a lot energy.
So they could work with less pain and more good output at the same working time.

HOW WE DO DRILLING

Drilling is also very important for wheel assembly and wheelset durability.

Bad drilling will get the incorrect angle, which makes pains for wheel-assembly.

The bad angle would also make a strain in the spokes and nipples, causing breaks.

Of course, this is a quite complicated issue indeed.

It would be related to the rim design, hub design, and could also improve by nipples.

For a rim manufacturer, we have to make sure the drilling angle is accurate and precise.
