We use gravity casting technology to produce trucks, there is another technology called die casting, I 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 |

HRB40 around |
suitable group |
can stand 150kg or more weight, who are very professional, do kickflip, backside, noseslide, etc these kinds of heavy movements often. |
can stand 95kg at most, who are very professional, do kickflip, backside, noseslide, etc these kinds of heavy movements often. |
If one professional guy stands on die casting trucks and makes heavy actions, it will maybe happen this:
Our trucks are made of gravity casting technology, after heat treatment, inside structure is very strong. You don't need to worry about quality :)
If you are interested in die casting and gravity casting technology on aluminum alloy material products and want to know more, you can check google. 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 :)
