CNC Machining Benefits for Your Project
Our CNC machining services support custom parts from early prototypes to repeat production, with flexible quantities, controlled dimensions, and finishing options around your project requirements.
Support prototype orders, low-volume production, and repeat parts based on your project needs.
Receive dedicated project support with replies within 12 hours for your CNC machining requirements.
Programmed CNC machining helps maintain consistent dimensions across multiple parts and repeat orders.
Tolerances to ±0.01 mm and surface roughness down to Ra 0.2 μm for applicable part requirements.
Use metal and engineering plastic materials suitable for functional testing, assembly checks, and end-use parts.
Validate part size, fit, assembly, and functional details with CNC-machined plastic parts before moving into mold making and injection molding.
When you order more parts, programming and setup costs are shared across the order, helping reduce the price per part.
Advanced post-processing technologies for improving appearance and material properties.
From CNC Prototypes to Injection Molding Production
Use CNC-machined plastic prototypes to validate fit, function, and assembly before mold making. When your design is ready, the same TryCooler team can support DFM, tooling, T1 samples, and repeat injection molding production.
Upload your CAD file to receive a detailed quotation and practical DFM feedback within 24 hours.
Use CNC-machined plastic parts to check size, fit, assembly, and functional details before releasing your design for mold making.
Get practical support for material selection, machining methods, tolerances, surface finishes, and assembly-related requirements.
Prototype changes, drawing updates, and validation feedback can be carried into mold design without re-explaining your project to a new supplier.
Review initial molded samples after tooling is completed, then confirm your part before repeat injection molding production begins.
Work with one project contact from quotation and drawing review through CNC machining, tooling, inspection, and shipment.
CNC Machining Surface Finishes for Your Part
Correct dimensions alone are not enough when your part must resist corrosion, reduce glare, match a specified color, or present a refined metal appearance. TryCooler offers 10+ surface finish options, including anodizing, bead blasting, polishing, brushing, powder coating, electroplating, and black oxide.
Choose as-machined for cost-effective functional parts, bead blasting and anodizing for a uniform aluminum appearance, polishing for smoother visible surfaces, or electroplating and black oxide for specified metal performance. We review your material, appearance requirements, and critical threads, holes, and mating surfaces before finishing to help protect both part function and final appearance.
CNC Prototypes for Design Verification and Engineering Testing
Before manufacturing the injection mold, we used CNC-machined prototypes to verify the fit of internal components, assembly details, and the overall dimensions of the housing. This approach effectively reduces validation time by 50% and lowers costs by 35%. Please send us your drawings to receive a quote for a CNC Machining Prototype for your project.
Custom Machining for Small-Batch End-Use Parts Production
Once your design is stable, CNC machining supports low-volume orders for functional parts, pilot builds, and early market validation. Programmed machining helps maintain repeatable dimensions across your order, with materials and finishes selected around your application requirements.
For plastic parts moving toward higher-volume production, TryCooler can continue with in-house mold making and injection molding.
Custom CNC Projects We Have Supported
See how TryCooler helps customers validate custom plastic parts through CNC machining before moving into mold making and injection molding production.
A U.S. industrial automation equipment manufacturer needed a production mold for a custom plastic enclosure with precise internal mounting features and consistent assembly fit. TryCooler used CNC mold machining, EDM, and cavity polishing to manufacture the core, cavity, and critical inserts, controlling key mold features to ±0.01 mm and creating a smooth cavity surface for the required part appearance. After mold testing, we supplied 5–10 T1 samples for the customer’s assembly review before injection molding production.
A consumer electronics brand needed a PC/ABS housing prototype to verify PCB clearance, connector locations, screw bosses, and enclosure fit before tooling. TryCooler reviewed the 3D CAD file, CNC-machined the housing, and checked assembly-critical features. The customer completed assembly testing with the prototype and then released the design for mold making.
Material: PMMA / PC
Process: CNC Milling
A consumer product company needed transparent PC or PMMA cover prototypes to review visible-surface quality, mounting details, and fit with the surrounding housing. TryCooler CNC-machined and polished the visible surfaces to achieve a smoother, clearer appearance for realistic product appearance evaluation. The customer confirmed the cover design and prepared the project for mold making and injection molding production.

CNC machining is an ideal solution for small-batch and low-volume parts. Pricing depends on the selected material, complexity, quantity, and required lead time. For similar geometries, CNC machining and 3D printing prices are relatively close, but CNC machining typically offers superior material properties and surface finish. The best way to get an accurate quote is to submit a 3D CAD model and receive an interactive quote that includes Design for Manufacturability (DFM) feedback.
CNC machining technology is widely used across various industries. It is commonly found in the automotive, consumer electronics, robotics, sports equipment, and household accessories sectors, among others. It is one of the most common manufacturing processes in the world.
All machined and sheet metal parts undergo standard inspection. We also offer additional inspection services that include detailed reports, such as first-article inspection (FAIR) and coordinate measuring machine (CMM) inspection. Please contact us for more information.
