Sourcing Forgings for New Energy Vehicle Hubs and Mounting Bases
We make custom forgings for new energy vehicle hubs and bases. In-house forging, heat treatment and precision machining for EV structural parts.
I’ve talked with dozens of EV procurement engineers over the years. One complaint comes up again and again. They source a low-cost blank, pass it to machining, and then fail durability testing. Cast parts look okay on drawings, but they struggle with the heavy battery weight and constant vibration that new energy vehicles deal with every day. That’s why many experienced buyers turn to forgings for hubs and mounting bases.
Forging squeezes solid metal under high pressure. It lines up the metal grain to follow where stress hits the part. This simple detail makes the part far less likely to crack or fatigue over time. For wheel hubs, this directly relates to driving safety. For mounting bases that hold batteries or drive units, stable structure keeps the whole powertrain steady through countless vibration cycles. We do our forging right here in our own workshop. No outsourced blanks. If you need a custom design, we can adjust die shape and pressing parameters early in the project.
Heat treatment is not an extra step we rush through. Each batch follows a thermal plan matched to its alloy and load requirement. Quenching, tempering and stress relief are all set case by case. Bad heat treatment locks residual stress inside the metal. The part may look perfect after machining, but warp later once assembled or under long running load. We save furnace data and run hardness checks for every lot. The hubs and bases you get will have steady, predictable mechanical properties.
Machining turns heat-treated forging blanks into finished parts matching your drawing. Our CNC team holds tight GD&T tolerances for mounting faces, bolt holes and bearing seats. Runout control matters a lot for hubs. Even a tiny offset brings vibration, noise and shorter bearing life. For large flat mounting bases, flatness and parallelism cannot be ignored. Uneven surfaces create uneven clamping force and stress on battery modules. We set aside proper machining allowance during forging, balancing cost and final accuracy.
A lot of suppliers only handle one process. One shop makes blanks, another does heat treatment, a third runs machining. When quality issues pop up, it takes weeks to sort out who is responsible. Our factory keeps forging, heat treatment and machining under one roof. All process records are traceable. Our technical team can adjust the whole workflow together when your design changes. This cuts miscommunication and speeds up sample development.
We support EV projects from sample phase. Some clients need lightweight hubs for passenger cars to extend range. Others need heavy-duty bases for electric commercial vehicles. We review your drawings, talk through material options, and work out a practical process plan before tooling starts. Small sample batches are available, so you can run bench tests and validation before mass production.
When you pick a forging supplier for new energy vehicles, price is not everything. You need a team that understands EV dynamic loads, controls every process carefully, and responds fast when specs shift. If you are developing new hub designs or looking for qualified mounting base forgings, send over your drawings and specs. We will reply with a practical proposal and honest lead time.
