Precision CNC Machined Aluminum Parts from China - Reliable Suppliers & Factory for Quality Components
Multi-axis CNC machining centers can complete complex milling, drilling, boring, and tapping processes in a single operation. This enables CNC-machined aluminum parts to achieve extremely high dimensional accuracy (typically within ±0.005 mm), ensuring perfect fit in critical applications without the risk of leakage or loosening.
In addition to CNC machining, other processes may be used depending on the product's structure and batch size. For example, for complex parts, FRIMA first uses high-pressure die casting to form the blank, followed by precision machining; for simple support components, stamping and bending processes are used.
To solve the challenge of joining dissimilar materials (such as aluminum tubing and steel), an advanced bimetallic adapter is available. It uses solid-state welding technology (such as rolling composite) to pre-bond aluminum and steel, then forms the material. This allows for easy welding of aluminum to the aluminum side and steel to the steel side using traditional arc welding, achieving a perfect combination of lightweight and reliable connection.
Vehicles: A high proportion of the shock inflicted by an automobile in a motor vehicle accident is absorbed primarily by its aluminum structure.
Air Travel: Strong aluminum alloys take the extreme pressures and stresses involved in high-altitude flying. Wafer-thin aluminum panels keep the cold out and the air in. Many internal fittings like the seating on airplanes are made from aluminum or aluminum composite in order to save weight and thus save fuel, reduce emissions and increase the aircraft's payload.
Transportation: The combination of lightness, strength, and malleability makes aluminum the ideal material for transportation applications. It is used in automobiles, airplanes, railways, and marine applications and also for making fuel-efficient engines in cars and trucks. Its low weight reduces fuel consumption and emissions.
Construction: Aluminum facilitates the construction of corrosion-resistant and low-cost buildings. All kinds of aluminum products are used for new construction as well as renovation and due to its strength and lightness, it is used in earthquake-prone zones. It is also a good reflector of light and is often used in lighting fixtures.
Electrical Transmission Lines: Aluminum can be drawn into thin wires which are often used in products such as light bulbs and telephone wires. Most of the high-voltage overhead transmission and distribution lines over long distances are also made of aluminum.
FRIMA uses a coordinate measuring machine to precisely measure geometric dimensions and tolerances; analyzes material composition using a spectrometer; verifies material strength through hardness testing; performs airtightness testing on adapters for high-voltage applications; and analyzes the weld microstructure using microscopy and SEM (scanning electron microscopy) to ensure the absence of harmful intermetallic compounds.
Our precision CNC machined aluminum parts comply with RoHS (Restriction of Hazardous Substances Directive) and REACH (Registration, Evaluation, Authorization and Restriction of Chemicals) regulations, ensuring they are free of hazardous substances such as lead and mercury.
