ZINKO Manufacturing Services
Custom CNC, molding, finishing, and production support.
Send drawings, samples, or RFQ details. We help review the right process, material, tolerance, finish, inspection points, packing, and delivery path before quoting.
Start by part type
Choose the route by geometry, not by guessing a process.
Many custom parts need more than one operation. ZINKO can start from the drawing and help match the part shape, material, tolerance, and finish to a practical production path.
Complex milled parts
Housings, brackets, plates, fixtures, pockets, threads, and multi-face features.
02Round components
Shafts, pins, spacers, bushings, rings, threaded parts, and cylindrical hardware.
03Plastic production parts
Shells, covers, caps, clips, housings, molded details, and production tooling review.
04Appearance and protection
Anodizing, plating, black oxide, passivation, polishing, powder coating, and marking.
Service categories
Manufacturing routes, organized by what the part needs.
Instead of treating every capability as a separate box, this board shows how each route fits into a complete custom-part workflow: machining, molding, finishing, prototype validation, and production support.
Metal and plastic parts
CNC Milling
Housings, brackets, plates, fixtures, pockets, threaded features, and complex custom components.
Round components
CNC Turning
Shafts, pins, bushings, spacers, rings, threaded parts, and cylindrical hardware.

Swiss Machining
Slender, high-repeatability turned parts and compact hardware with tight features.
Hard metal profiles
Wire EDM
Accurate cutting for hard metals, slots, sharp internal corners, tooling details, and cut profiles.

Anodizing, plating, black oxide, passivation, polishing, powder coating, and part marking.
Design validation
Prototype Samples
Fast samples, fit checks, functional testing, and small batches before production.
Process guide
A quick way to choose.
If you are not sure which process fits, send the drawing and target use. We can recommend machining, molding, finishing, or a combined route.
How we work
From files to finished parts without losing the details.
The service is built around clear review points, so custom parts do not drift between quotation, production, finishing, inspection, and shipment.
Send Files
Share 2D drawings, 3D files, samples, material, quantity, finish, and delivery needs.
Review & Quote
Manufacturability, key dimensions, tolerance risks, material, and process options are reviewed.
Manufacturing
CNC machining, EDM, molding, finishing, and secondary processing are coordinated as required.
Inspection
Parts are checked for dimensions, finish, appearance, and packing condition before shipment.
Delivery
Safe packing and flexible shipping support for international customers and repeat production orders.
Beyond machining
Support from drawings to packed parts.
Custom parts often need more than one supplier step. ZINKO helps review drawings, confirm materials, coordinate finishes, check appearance, and prepare parts for shipment.
