Automotive Parts Manufacturing FAQ
Is Meco IATF 16949:2016 certified?
Yes. Meco's quality management system is certified to IATF 16949:2016 across our manufacturing facilities. Built on ISO 9001:2015, our system integrates APQP, PPAP, SPC, MSA and PFMEA controls into every automotive program.
What PPAP levels and quality documents do you provide?
We supply AIAG-compliant PPAP packages from Level 1 to Level 5, including the Part Submission Warrant (PSW), Process Flow Diagrams, PFMEA, Control Plans, CMM dimensional results, Cpk capability studies, IMDS material entries, mill certificates and serialized lot traceability.
Can you scale from prototype to high-volume serial production?
Yes. We support 10-piece functional prototypes and bridge tooling in 1 to 3 weeks, then transition into multi-cavity or progressive-die hard tooling for annual volumes (EAU) of 10 million+ units under the same engineering team.
How do your Thailand and China factories help reduce tariffs and supply chain risk?
Meco operates IATF 16949-certified plants in both Thailand (20,000 m²) and China (16,000 m²), supported by U.S. engineering and Canadian headquarters in Richmond Hill, Ontario. Dual-country manufacturing lets North American and global buyers optimize landed tariff costs and maintain backup production capacity.
Who owns the molds, dies and production tooling?
You retain 100% ownership of all custom die-casting dies, injection molds, forging dies, stamping tooling and fixtures paid for under your program. Meco maintains, stores and insures your tooling exclusively for your orders.
How fast can we get a quote and DFM review?
We return a detailed quotation and Design for Manufacturability (DFM) review within 24 hours of receiving your 3D CAD models, 2D drawings, material specs and Estimated Annual Usage (EAU). See our metal part pricing guide for budgeting tips.
From Prototype & PPAP to Serial Production
Send 3D models, 2D drawings, material/finish callouts, Estimated Annual Usage (EAU) and required PPAP level.
Receive pricing within 24 hours along with APQP/DFM feedback to optimize tolerances, cycle time and tooling cost.
Machined parts go straight to off-tool samples; for cast, forged, stamped or molded parts, we build customer-owned tooling.
Approve T1 samples backed by your full PPAP package (Levels 1–5), CMM layout reports, Cpk studies and IMDS data.
Meco runs SPC-monitored mass production, surface finishing, assembly and JIT delivery from Thailand or China.
