Custom CNC Milled Aluminum Parts
Custom CNC Milled Aluminum Parts
Every project FRIMA take on begins with the right raw material. The performance, machinability, and surface finish of your Custom CNC Milled Aluminum Parts hinge on selecting the optimal grade. At FRIMA, we stock and process a wide spectrum of aerospace, automotive, and medical-grade aluminum alloys, all with full mill certification and traceability back to the original heat number.
Aluminum Materials We routinely work with
6061-T6
Our versatile standard for prototypes and general-purpose structural components. We select 6061-T6 when you need an excellent strength-to-weight ratio, reliable weldability, and a predictable anodizing response.
7075-T6
When your design demands high strength comparable to many steels, we machine 7075-T6. This alloy is our go-to choice for stressed aircraft fittings, competition automotive parts, and high-impact tooling.
5083
We recommend 5083 for projects where exceptional corrosion resistance is paramount. It is our first choice for marine hardware and cryogenic applications.
6082
For European automotive and structural applications, we often use 6082. It offers a robust medium-strength profile that our customers trust for demanding mechanical loads.
2024
We machine 2024 when high fatigue resistance is critical, such as for aerospace skins and rotating parts.
MIC 6 / ATP 5
For jigs, fixtures, and electronic mounting plates that demand unmatched flatness, we use cast aluminum tooling plate with built-in stress relief.
If you don't see your specific grade listed, please ask. Our supply chain network sources uncommon alloys and tempers on demand. Every shipment we send includes material certificates as part of our standard documentation package.

How We Solve Your Toughest Manufacturing Challenges
Our 8,000 sq. ft. machine shop, now expanded to a 5,000 square meter dedicated production facility, gives your Custom CNC Milled Aluminum Parts a seamless, single-roof manufacturing journey. We combine advanced 3-axis and multi-axis machining centers with turning, drilling, tapping, facing, cross-drilling, and integrated assembly workcells. Because we never subcontract, there are no communication gaps and zero quality leaks.
What industry buyers hate—and how FRIMA fixes it
Pain 1: “I need 30 prototypes, but most shops demand 500+ MOQ.”
FRIMA is engineered to be nimble. We specialize in non-standard, custom-made components and welcome low-volume orders as small as 1 piece. Our rapid prototyping workflow delivers functional samples within 7 business days, allowing your engineering team to test, iterate, and lock the design before committing to volume production. You pay for what you need—never a piece more.
Pain 2: “The first sample was perfect, but batch quality tanked.”
We eliminate this risk with an IATF 16949-certified quality management system designed for the automotive supply chain’s zero-defect philosophy. From first-article inspection (FAI) to full PPAP Level 3 submissions, our full-time quality personnel and documented procedures lock in process stability. In-process checks, final dimensional reports, and CMM data sheets come standard with every batch.
Pain 3: “My anodized parts have a colour mismatch between batches.”
FRIMA operates in-house professional surface treatment services exactly for this reason. Our controlled anodizing, hard coat anodizing, electroplating, powder coating, and painting lines follow precisely defined parameter sheets—tank temperature, current density, dye concentration—to deliver repeatable, consistent aesthetics and functional properties. No more managing three vendors; we grind, deburr, heat-treat, and finish your parts under one roof.
Pain 4: “The parts arrived damaged. Now my project is delayed by two weeks.”
We’ve designed packaging protocols that match the rigour of our machining. Every batch of aluminum parts undergoes a final cleaning, followed by VCI (volatile corrosion inhibitor) paper wrapping or anti-rust oil application for sensitive alloys. Parts are then secured in custom-cut polyethylene foam trays or thermoformed inserts before entering double-wall export-grade cartons or plywood crates. For shipments requiring ultimate protection, we provide vacuum sealing with desiccant bags. The result: your parts arrive as pristine as they left the CMM room.
Precision-CNC-Machined-Aluminum-Components
Complete One-Stop Surface Finishing
Your machined parts often need more than clean edges. FRIMA’s integrated finishing department takes over immediately after the last chip falls from the spindle. We offer:
● Mechanical finishing. Precision grinding, vibratory deburring, and abrasive blasting to achieve uniform matte or satin textures.
● Chemical and electrochemical treatments. Clear and coloured anodizing (Type II and Type III hard coat), chromate conversion coating, and electroless nickel plating for exceptional wear and corrosion resistance.
● Aesthetic and protective coatings. Liquid painting, powder coating, laser engraving, and silk screening.
When we manage the entire handoff from milling to finishing, you avoid the all-too-common finger-pointing between a separate machine shop and plating house. You get one accountable partner, governed by one quality standard.

Packaging and Shipping
As a buyer, you know that a perfectly machined part is worthless if it arrives scratched or corroded. Our location adjacent to Ningbo Port, the world’s busiest cargo gateway, and just minutes from Shanghai Airport has given us deep expertise in packaging that protects your parts across any shipping mode. Here is how we do it:
● Individual part protection. We apply VCI film, anti-rust tissue, or finger cots to protect delicate threads and bores.
● Layered containment. We use static-dissipative foam inserts for electronic housings, or high-density EPE tray cavities CNC-routed to your part profile.
● Outer fortification. For sea freight, we build 7-layer plywood export crates reinforced with steel banding. For air courier via DHL, FedEx, UPS, or TNT, we select lightweight yet robust double-wall cartons.
● Consolidation expertise. We batch-order to match your production schedule and can warehouse partially completed inventory, shipping precisely when you need it. This reduces your on-site stockholding burden.
● Typical air freight reaches your facility in under 7 business days. Sea freight consolidations benefit from daily sailing schedules out of Ningbo, which minimizes port dwell time.

After-Sales Support That Keeps Your Production Line Moving
Our commitment to you does not end at the Bill of Lading. We structure our after-sales service around three core needs we know manufacturing buyers have: speed of response, technical competence, and commercial fairness.
48-hour technical escalation. Your dedicated project engineer, assigned from the very first quote stage, remains your single point of contact after delivery. Any dimensional or functional query you raise receives an engineering analysis, not a scripted customer service reply, within two working days.
Full traceability archive. We retain digital part inspection reports, material certificates, and process parameter logs for a minimum of 3 years. If you need to audit a batch from 18 months ago, we will email your full documentation pack the same day you ask for it.
Root cause and corrective action. Should a non-conformance ever arise, FRIMA executes a formal 8D or CAPA process approved by our quality manager. You receive a preventive action plan that addresses the process, not just the symptom.
Revision management. We understand that engineering changes are a fact of life. Our team maintains strict revision-level controls, quarantining superseded drawings and ensuring only the latest release hits our production floor. We also offer fast-turn rework or modification of existing parts when your design evolves.
