How We Work

Simple
Process.

Step 01

Send Your Brief

Email us a drawing (DXF/STEP/PDF), a physical sample, or even just a rough description. We’ll ask the right engineering questions and come back with a real quote — not a ballpark.

Response: 24 hrs
01
Step 02

Sample & Validate

We machine pre-production samples for fitment and quality validation. Stock samples are free; custom parts require an upfront tooling fee that is fully credited back on your bulk order.

4–6 weeks
02
Step 03

Production

30% deposit starts the run. You’ll get weekly photos and progress updates. CMM measurement records are taken mid-production. No batch leaves the floor without dimensional sign-off.

30–45 days

Step 04

QC & Delivery

Final inspection, QC report, material certs, and customs docs prepared before dispatch. 70% balance before shipment. Air or sea — we handle the logistics paperwork.

Common Questions

Got
Questions.

Straight answers to what OEM buyers ask before placing their first order with us.

Ask Anything

Minimum 50 pcs per line item, or a $500 minimum order value. This applies to standard catalog parts and custom OEM orders. Smaller prototype quantities can be discussed — just ask.

Yes. We accept 2D drawings (DXF/DWG/PDF) and 3D files (STEP/IGES). We also reverse-engineer from physical samples. Our engineers review your design for manufacturability and suggest improvements before production.

Structural steel, chrome-moly (4130/4340), stainless steel (303/304/316L/17-4PH), 6061-T6 / 7075-T6 aluminium, titanium alloys, and engineering plastics for bushings and spacers.

Black oxide, zinc plating, nickel plating, hard chrome plating, hard anodizing (Type III), standard anodizing (Type II), powder coating, and Dacromet coating. Most processes are done in-house.

Yes. For standard in-stock parts, samples are free (freight covered by customer). For custom parts requiring new tooling, we charge an upfront tooling fee. This fee is 100% refunded or credited back once your subsequent bulk order meets our minimum volume requirement.

Wire transfer (T/T) and PayPal. Standard terms: 30% advance to start production, 70% balance before shipment. Long-term customers may arrange adjusted terms on request.

No. While automotive is our core, we supply parts for marine hardware, wind turbine pitch and yaw systems, agricultural machinery, construction equipment, and industrial automation. If it pivots, slides, or oscillates, we likely make the part.
