Dear Manager,
This longboard trucks are made by die casting technology by good aluminum alloy
material. There is another technology called gravity casting, I kindly list their difference
below:
| comparison | gravity casting technology | die casting technology |
productive principle | Aluminum liquid flow into truck mould by liquid's weight naturally, this way can delete mould's inside air clearly. | To push aluminum liquid into truck mould by other pressure quickly. Can't delete mould's inside air clearly. |
whether has heat treatment | can do heat treatment after demoulding. | Can't do, because there is small air bubble under truck skin, the skin surface will be embossed if heat trucks. |
| truck surface | A little rough, because of heat treatment. | Very smooth. |
| producing speed | very slow, because of heat treatment, which contains solution treatment and artificial aging treatment. | very quick, can use immediately after demoulding. |
| price | Twice price than die casting. | Half price than gravity casting. |
| strong level | HRB65 around | HRB40 around |
| suitable group | can stand weight over 150kg, or who are very professional, do kickflip, backside, noseslide, etc these kinds of heavy movements often. | can stand 95kg at most to do kickflip, backside, noseslide, etc these kinds of heavy movements often. |
If you are interested in die casting and gravity casting technology on aluminum
alloy material products, you can check google. In our shop we have both gravity casting
and die casting trucks. In order to enhance our die casting truck strong level, we use
aluminum alloy A356.2, this material is the best suitable for skateboard trucks. You can
check our samples first before massive order :)
we are very confident in our truck quality, and we offer you one year quality
warranty, if our trucks break, we are willing to send you new items or just refund you
money.
Cheers-Metal Lee
