What Our Customers Say
Feedback from engineering, procurement, and quality teams who source die casting parts from our Nanjing facility.
“KastMfg took over a program mid-launch and delivered 40,000 parts with zero dimensional rejects over 18 months. Their DFM feedback caught a gate location issue our previous supplier missed.”
Automotive Tier-1, Germany
EV motor housing — aluminum HPDC
“We needed CT4 tolerance on a complex hydraulic manifold with 12+ machined ports. KastMfg's process control plus in-house CNC made it a single-vendor solution that saved us 6 weeks of coordination.”
Industrial Equipment, USA
Hydraulic manifold — ADC12 aluminum
“The English-first communication and packing quality made repeat orders straightforward. Magnetic particle inspection reports came in-shape with every shipment — no back-and-forth.”
Security Hardware, UK
Lock bolt body — Zamak 5 zinc HPDC
“We were stuck with a supplier who couldn't hold wall thickness on magnesium EMI housings. KastMfg's mold flow analysis and parameter tuning fixed it within the first tryout.”
Telecom Equipment, Sweden
5G enclosure — AZ91D magnesium
“From first DFM review to PPAP approval in 8 weeks. Their tooling lead time beat our previous supplier by 3 weeks, and the CMM report matched our incoming inspection exactly.”
Automotive OEM, Australia
Chassis bracket — A380 aluminum
“We source 12+ SKU from KastMfg annually. Consistent surface finish, on-time delivery, and 8D reports when needed make them a reliable production partner.”
Consumer Electronics, France
Heat sink series — ADC12 aluminum
