With our Custom Online CNC machining service, you can upload your drawings, get fast quotes, and start production without any hassle. We machine your parts exactly to spec using reliable CNC milling, turning, and finishing processes — giving you consistent quality, quick lead times, and a smooth online experience from prototype to production.
CNC Machining Service for Custom Parts
Precision CNC milling and turning for prototypes and production parts, we deliver tight tolerances, complex geometries, and consistent quality tailored to your specifications.
CNC Milling Parts
CNC Milling is used to apply a machined surface finish on engineering-grade plastic or metal for creating complex 3D shapes. KH Mold use high precision CNC machining centers with quick-change tooling. KH Mold toolpaths the digital part design to our CNC machines. During the machining process, a solid block of material is clamped into a CNC mill and cut into a finished part. The range of material choices allows parts to be made with the desired material properties, and good tolerances yield parts suitable for form, fit and function testing.
Wire EDM Parts
Wire EDM, or electrical discharge machining, is a high-precision method for cutting nearly any electrically conductive material. KH Mold provides first-class Wire EDM services. Equiped with slow-feeding Wire Cut machines with a tolerance of 0.002mm and Mirror EDM machines with a tolerance of 0.005mm, we can manufacture even the most intricate parts with perfect accuracy and repeatability, whether you need prototypes, short production runs, or quantities in the tens of thousands.
CNC Turning Parts
CNC Turning is a manufacturing process in which components or bars of materials are held in a chuck and rotated while a cutting tool removes material from the piece to create the desired shape. The cutting tool is controlled by a computer, which allows for accurate and repeatable processes.
Machined Parts
When you work with us for machined parts, you get precision components made exactly to your specifications. Whether it’s for automotive, electronics, medical, or industrial projects, our advanced CNC processes ensure consistent quality, smooth surfaces, and reliable performance — so your production runs smoothly every time.
CNC Machining Service for Custom Parts
CNC machining service is suitable for engineering-grade plastic or metal parts and can be used to make from one single prototype up to hundreds parts. A wide variety of materials can be machined, including stainless steel, aluminum, magnesium, zinc, brass and much more.
We offer the production of precision-machined components. Our precision engineering department offers milling, CNC engineering, surface grinding, wire cut, mirror EDM erosion and more. All of your projects will be discussed carefully and checked before production starts. During and after production the parts will be 100% inspected. We can provide original certificates for all materials used in the project as well.
