01 Manufacturing Processes
How machining, casting, forming, finishing and assembly are chosen for a given geometry, material and volume.
ENGINEERING SUPPORT
Engineering Support & Technical Resources for Custom Mechanical Parts
ATOS supports custom mechanical parts projects with engineering review, process selection, inspection planning and quotation support. The pages below explain how we actually work, and each one links to the technical capability behind it.
- Process, material and inspection references tied to real production pages
- Engineering review and DFM feedback before tooling is cut
- Quotation, sampling and delivery support for North American buyers
Need a Reference or a Second Opinion?
Send us the drawing or just the question. We will tell you which process fits, what tolerance is realistic, and what we would need to quote it - including the case where we are not the right shop for the part.
Send Your Technical Request →What This Section Covers
Four areas that come up in almost every custom parts project. Each one links to the page that explains it in detail.
02 Materials & Surface Treatment
Material grades, coatings, plating, heat treatment and corrosion requirements we can work to.
03 Testing & Inspection
CMM measurement, NDT, material verification, salt spray testing and the documents behind them.
04 Drawings & RFQ Preparation
What to send for a usable review: 2D drawings, STEP or IGES files, samples, quantities and tolerances.
TECHNICAL REFERENCE PAGES
Six Pages That Answer Most Sourcing Questions
These are the technical pages on this site. They cover how parts are designed, validated, manufactured, inspected and delivered - written for buyers and engineers who need to judge whether a supplier can hold the requirement.
01
Design & Simulation
Finite element review, tolerance stack-up and design-for-manufacturing feedback before tooling is cut.
02
Simulation & Testing
Test benches, durability runs, leakage checks and performance validation for parts under load.
03
Manufacturing Processes
Machining, casting, stamping, forming, welding and surface finishing compared against your volume.
04
Testing & Inspection
Incoming material checks, in-process measurement, CMM reports and final inspection documentation.
05
Supply Chain & Service
Tooling ownership, repeat-order planning, packing and export documents for North American buyers.
06
Product Capabilities
The eight component families we build for gas station equipment, industrial OEM and commercial vehicles.
If a requirement is not covered on these pages, it is usually faster to ask directly than to search for it.
HOW A PROJECT MOVES
From Drawing to Quotation in Four Steps
No account, no download, no form to fill in before you get an answer. This is the sequence every custom parts project goes through with our engineering team.
01
Send drawings or a sample
PDF, DWG, DXF, STEP, IGES, photos or a physical part - whatever you have at this stage.
02
Engineering review
We check geometry, material, tolerance and volume, then say what is feasible and what is not.
03
Process route and DFM notes
We propose the manufacturing route and flag the changes that reduce cost or risk before tooling.
04
Quotation and sample plan
Price, lead time, MOQ and sample schedule in writing, against the exact drawing revision you sent.
