IATF 16949 Certified · Stamping · Dies · CNC · Welding One-Stop Manufacturer since 2011 Rapid 24-hour quotation. Free design analysis for your custom automotive project.
With years of experience, Chassis Welded Assemblies is committed to delivering innovative product stability and strength, specializing in auto sheet metal welding to meet the demands of the automotive industry.
Auto stamping parts combine CAE analysis with lean manufacturing practices, effectively reducing development cycles and costs while ensuring high precision and reliability.
We offer 24-hour quotations and a 72-hour rapid design capability for CNC automotive parts, ensuring swift responses to meet customer needs efficiently.
Shaoyi specializes in the design and manufacturing of automotive stamping dies, offering precision-engineered solutions to meet complex production requirements. Our molds ensure high efficiency and consistency, making them the ideal choice for automotive applications.
Shaoyi competes on engineering response and process transparency rather than price alone. Every promise below is a standing operating commitment, not a campaign.
Shaoyi returns a formal quotation within 24 hours and a technical/DFM analysis within 12 hours of receiving your 2D/3D drawings — 72 hours for rapid CNC design. Faster feedback shortens your program timeline before tooling is committed.
Shaoyi engineers run formability and feasibility analysis at no cost, flagging springback, thinning and tolerance risks before a die is cut. Design corrections at this stage cost a fraction of a tooling rework.
The Shaoyi engineering team has more than ten years of automotive component design experience across chassis, suspension and shock‑absorption systems, so DFM feedback comes from people who have launched these parts before.
Production, quality feedback, delivery and progress all run on MES systems, giving buyers real‑time transparency plus weekly progress reports with photographs and video instead of a factory visit.
Every project can be covered by NDA, and each customer is assigned a dedicated sales consultant who owns communication from RFQ through mass production.
Shaoyi powers production with green photovoltaic energy, supporting the sustainability requirements increasingly written into Tier‑1 supplier scorecards.
Upon request, our engineers can provide hands-on technical support at your facility, from tooling installation and tryout to production ramp-up.
