Automotive Parts Manufacturing
One IATF 16949-certified partner for car parts, from the first sample to millions of units. CNC machining, die casting, forging, stamping, molding, and assembly, all in one place.
What Is Automotive Parts Manufacturing?
Automotive parts manufacturing is how car parts get made. That means everything from engine blocks and gearboxes to EV battery trays and small sensor brackets. Meco makes these parts using methods like CNC machining, die casting, metal stamping, forging, and injection molding. Every part has to be the right size and pass safety checks.
Car parts have one big extra rule called IATF 16949:2016. It is the quality standard that car makers ask for. It builds on ISO 9001:2015 and adds steps like APQP and PPAP so parts stay safe and consistent. Meco has followed this standard for over ten years, so car brands and their suppliers get one turnkey automotive manufacturing partner from the first sample all the way to full production.

From Prototype to Full Production
Building a new EV part or scaling an existing one? Our process takes you from the first sample to full production under one quality system, with no need to switch suppliers along the way.
Our engineers look at your CAD and suggest changes that fit your process, often cutting cost by 15 to 30% before we cut any metal.
We build working samples in real production materials. They are ready in 1 to 3 weeks so you can check fit, form, and function.
We build the tooling with T0/T1 samples and send full PPAP docs, control plans, process flow, and FAI, for your sign-off.
Full runs with in-process SPC, CMM checks, and 100% final inspection. Parts ship with full docs and car-grade packaging.
Scale from 10 to 10 million+ parts. Our APQP process drives ongoing improvement and yearly cost-down on long programs.

Automotive Parts Manufacturing FAQ
What is automotive parts manufacturing?
It is the making of car parts like powertrain, chassis, interior, and EV parts. It uses methods like CNC machining, die casting, forging, stamping, and injection molding, and follows car standards such as IATF 16949:2016.
What certification should an automotive parts maker have?
The top one is IATF 16949:2016. It includes ISO 9001:2015 and adds car-only steps for APQP, PPAP, SPC, and PFMEA. Meco holds this across its factories.
Can you go from prototype to full production?
Yes. We cover the whole path, from rapid prototyping (as few as 10 parts) through PPAP approval to 10 million+ units. Same factory, same quality system, no switch risk.
What car parts do you make?
Powertrain (engine blocks, gearbox housings, shafts), EV parts (battery trays, motor housings, bus bars), and chassis and suspension parts. See our parts section.
What processes do you offer?
40+ processes including CNC machining (3/4/5-axis), die casting, forging, metal stamping, injection molding, surface finishing, heat treatment, and assembly, all in-house.
What materials do you work with?
Metals: aluminum (6061, 7075, ADC12, A380), stainless (303, 304, 316), carbon steel, brass, copper, titanium, zinc, and magnesium. Plastics: Nylon, Delrin, ABS, PC, PEEK, glass-filled Nylon, TPU, TPV, and TPE.
How does rapid prototyping work for car parts?
We make working test parts in real production materials, not just 3D prints. Using CNC machining, die casting, and molding, we deliver samples in 1 to 3 weeks so you can check fit, form, and function before tooling.
How much does it cost to make a part?
Cost depends on the process, material, volume, and finish. Our metal part pricing guide explains the main drivers, and DFM changes can cut cost 15 to 30%.
Where are your factories?
We run IATF 16949-certified factories in Thailand (20,000 m²) and China (16,000 m²), with offices in Toronto, Canada. Two locations mean fewer supply risks, more tariff flexibility, and North American support.
