Custom CNC Machined Carbon Fiber Parts

FlexiTurn provides CNC post-machining for carbon fiber intake manifolds and similar high-performance composite parts. Using 5-axis simultaneous machining, we complete flanges, ports, runner profiles, seal grooves, and hole patterns in one setup, controlling flatness, hole position, and contour accuracy for sealing and airflow performance. Cryogenic CNC options reduce cutting heat, minimizing resin softening and fiber delamination. We also offer DFM optimization, molding alignment, clear lacquer finishing, and laser marking.

Services cover prototyping to production for high-performance automotive,  aerospace auxiliary structures, and industrial automation. Quality includes material traceability, in-process inspection, and final dimensional verification to customer drawings.

Q1. What types of machining services do you offer?

We provide comprehensive CNC turning and milling services. FlexiTurn machines are equipped with 8-station programmable turrets and support both turning and 5-axis milling operations, making them suitable for everything from simple cylindrical parts to complex multi-axis components.

Q2. What materials can you work with?

We machine a wide range of materials including carbon steel, stainless steel, aluminum, plastics, and other engineering-grade materials. If you have a specific material in mind, just send us your requirements and we'll confirm feasibility.

Q3. What is your typical lead time?

Lead times vary depending on part complexity, quantity, and material availability. For prototypes and small-batch runs, we typically deliver within 5–10 business days. For high-volume production, we'll provide a customized schedule after reviewing your drawings. Contact us with your project details for an accurate timeline.

Q4. How do you price your services?

Pricing is based on several factors: material cost, machining time, tooling requirements, setup complexity, and order quantity. We offer competitive rates for both low-volume prototypes and high-volume production runs. Request a quote with your CAD files or drawings and we'll get back to you within 24 hours.

Q5. What quality control measures do you have in place?

We follow strict quality control procedures throughout the machining process. Our CNC systems support programmable precision down to 1 μm, ensuring high accuracy and repeatability. Every batch undergoes dimensional inspection before shipping, and we can provide inspection reports upon request.
