What Manufacturing Services Does XC Machining Offer?
XC Machining runs eight core services in one factory. You send a CAD file, pick a process, and we make the part. That is on demand manufacturing: no long contracts and no minimum order. CNC machining and 3D printing work as rapid manufacturing services, with parts leaving in days. Our online manufacturing services start with a quote request: upload a file, choose a material, and we reply within 24 hours.
Which process fits your part?
| If you need | Choose | Key spec | Speed or volume |
|---|---|---|---|
| A tight tolerance metal or plastic part | CNC machining | ±0.005 mm on metals, ±0.01 mm on plastics | Most prototypes ship in about 3 days |
| A complex part with compound angles | 5 axis CNC machining | ±0.005 mm in one setup | Complete parts without reclamping |
| A complex shape with no tooling | 3D printing | Layers down to 25 μm | 2 to 5 days |
| Plastic parts in volume | Injection molding | SPI finishes A-1 to D-3 | 1,000 to 1,000,000+ parts, first articles in 15 to 25 days |
| Light metal housings in volume | Die casting | Walls to 0.8 mm, ±0.05 mm | Makes sense from about 1,000 parts to 500,000+ |
| Enclosures, brackets and panels | Sheet metal fabrication | 0.5 mm to 6 mm material | Laser, plasma and waterjet cutting, then bending and welding |
| 20 to 50 copies without a steel mold | Vacuum casting | About ±0.1 mm | About 10 days |
| A real part before you pay for tooling | Rapid prototyping | Machined, printed or cast | 3 to 5 days |
Our CNC machining services run 3, 4 and 5 axis mills and lathes. We cut aluminum, steel, titanium, brass and most engineering plastics, and we hold ±0.005 mm on tight work. As a custom CNC parts manufacturer, we run prototypes and production on the same machines.
Best for tight tolerance metal parts.
Our 3D printing services use five technologies: SLA, SLS, FDM, MJF and SLM. That lets the process fit the part, not the other way round. Layers go down to 25 μm. With no tooling, parts arrive in 2 to 5 days, and you can change the file as needed.
Best for complex shapes and quick design checks.
Our injection molding service runs ABS, PC, Nylon, PP, PEEK and about 50 other resins. The tool is built for your volume, so a 5,000 shot mold costs less than one rated for a million. First articles land in 15 to 25 days.
Best for plastic parts above 1,000 pieces.
Our die casting service covers aluminum, zinc and magnesium at high pressure. We can hold walls as thin as 0.8 mm and tolerances at ±0.05 mm. The economics start around 1,000 parts and keep working past 500,000.
Best for strong, light metal housings in volume.
We cut with laser, plasma and waterjet, then bend and weld to your drawing. Anything from 0.5 mm shim stock up to 6 mm plate, usually steel or aluminum. Powder coating, anodizing and plating are in house.
Our vacuum casting service pours urethane into silicone molds pulled off a master pattern. It is the right call for 20 to 50 copies when steel tooling is too early. Accuracy sits around ±0.1 mm and parts land in about 10 days.
Best for look alike prototypes and small batches.
A 3 axis mill has to reclamp the part to reach each face, and every reclamp costs a little accuracy. On a 5 axis CNC machine the head tilts, not the part, so complex parts come off in one setup at ±0.005 mm.
Best for parts with undercuts and compound angles.
Most engineers want a real part in hand before they pay for tooling. Our rapid prototyping team machines, prints or casts it, whichever suits the design, and prototypes leave in 3 to 5 days.
Best for checking fit and function before you commit to a mold.

Frequently Asked Questions About XC Machining Services
What manufacturing services does XC Machining offer?
XC Machining is a custom manufacturing company with eight core services: CNC machining, 5 axis CNC machining, 3D printing, injection molding, die casting, sheet metal fabrication, vacuum casting and rapid prototyping. A common path is a CNC or printed prototype, a small urethane cast batch, then an injection mold for volume. Our engineers suggest the mix that fits your part.
How do I choose between CNC machining, 3D printing and injection molding?
Choose by volume, tolerance and material. CNC machining suits tight tolerance metal and plastic parts from a single piece. 3D printing suits complex shapes and quick checks, with no tooling. Injection molding costs more up front for the mold, but it gives the lowest cost per part past roughly 1,000 pieces. Upload your file and our DFM engineer will name the best fit.
What production volumes does XC Machining handle?
We handle one part to hundreds of thousands. Prototypes start at 1 piece, and bridge runs of 50 to 500 parts fit CNC machining or sheet metal. Injection molding covers 1,000 to 1,000,000+ plastic parts, and die casting runs from about 1,000 to over 500,000 metal parts. We pick the process by cost per part at your volume.
What is the lead time for CNC prototypes?
Most CNC prototypes ship in about 3 days, and the range is 3 to 7 business days depending on size, material and finish. Anodizing, plating and other finishes add time. 3D printed parts take 2 to 5 days, vacuum cast parts about 10 days, and injection molding first articles 15 to 25 days. Your quote gives the lead time for your exact part.
Does XC Machining offer design for manufacturing (DFM) feedback?
Yes. A free DFM review comes with every quote, and an engineer replies within 12 hours. The team checks wall thickness, corner radii, undercuts, draft angles, tolerances and tool access in your CAD file. The notes show what to change and why. A thin wall or missing draft angle costs nothing to fix at quote stage, but a lot once the mold is cut.
Does XC Machining ship parts to the USA and internationally?
Yes. We ship from Dongguan by DHL, FedEx or UPS, with full tracking and delivery confirmation, and we have shipped to 120+ countries. Our team answers by email, WhatsApp or phone at any hour, so time zones do not hold up your project. Tell us your delivery deadline when you upload your file so the quote reflects it.
How does XC Machining protect my designs and files?
Your uploads are confidential, and files move over encrypted connections between you and our team. You can ask your account manager, or email us, for a signed non-disclosure agreement before you share a drawing. Confidentiality terms also appear in our General Terms of Sale. Our IP protection policy has the details.
How do I get a manufacturing quote?
Upload your CAD file in STEP, IGES, STL or PDF format. Choose your material, finish and quantity, and our engineers review the design. You get a quote with cost, lead time and tolerances within 24 hours. There is no minimum order, and the DFM review is free. STEP files usually give the cleanest and fastest quote.
