Overmold Capable
Program Overview
EV charging station housing molds are production tools built for manufacturing outdoor-rated enclosures including AC wallbox covers, DC cabinet front panels, pedestal housings, cable management covers, and connector docking stations. Tooling is developed from customer CAD data with gating strategy, warp analysis, and sealing surface validation completed before steel procurement. Molds are designed to accommodate flame-retardant PC/ABS, PC, ASA, and glass-filled PA grades, with wall thickness control for dielectric strength requirements. Deliverables include DFM reports, mold flow analysis, steel certificates, T1 sampling, dimensional inspection, IP sealing verification support, and PPAP documentation for infrastructure and OEM qualification programs.

Procurement FAQ
Q What data is required to quote a charging station housing mold?
3D part data (STEP / IGES / native CAD), 2D drawing with tolerance and datum scheme, material specification including flame rating, annual volume forecast, IP sealing requirement, machine tonnage available, and target cycle time if defined.
Q What is the typical lead time for EV housing tooling?
Standard lead time is 45–60 days for single-cavity wallbox housings and 60–80 days for large DC cabinet panels or tools with complex slide systems, sealing grooves, and overmold requirements. Lead time begins after design freeze and includes T1 sampling.
Q How are sealing surfaces controlled for IP-rated enclosures?
Gasket and O-ring grooves are machined to ±0.05 mm tolerance with dedicated polishing of seal contact surfaces. Groove geometry is validated during T1 sampling with seal compression measurement and, when required, IP spray or immersion testing support.
Q How is warpage controlled on large cabinet panels?
Warpage is controlled through balanced conformal cooling, sequential valve gating, rib and boss structure optimization, and validated packing pressure profiles established during mold flow simulation. Dimensional verification is performed on T1 samples against the customer datum scheme.
Q What after-sales support is provided?
Support includes remote process troubleshooting, spare parts supply, wear insert replacement, hot runner service, texture restoration, and on-site technical assistance for production ramp-up when required.
