FRIMA Processes
CNC Precision Machining
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.
Multiple Forming Processes
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.
Bimetallic Adapters
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.

Advantages
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.

Frequently Asked Questions
1
What dimensional accuracy can FRIMA's CNC-machined aluminum parts achieve?
FRIMA's multi-axis CNC machining centers can achieve extremely high dimensional accuracy, typically within ±0.005 mm. This precision ensures a perfect fit in critical applications, eliminating risks such as leakage or loosening.
2
What manufacturing processes does FRIMA use besides CNC machining?
Depending on the product's structure and batch size, FRIMA also employs high-pressure die casting to form blanks for complex parts followed by precision machining, as well as stamping and bending for simpler support components.
3
What is a bimetallic adapter and how does it work?
A bimetallic adapter is a component designed to join dissimilar materials such as aluminum tubing and steel. It uses solid-state welding technology (e.g., rolling composite) to pre-bond aluminum and steel. This enables standard arc welding on each respective side — aluminum to aluminum and steel to steel — providing a lightweight yet highly reliable connection.
4
How does FRIMA ensure the quality of its aluminum parts?
FRIMA employs a comprehensive quality assurance process including coordinate measuring machines for dimensional verification, spectrometer analysis for material composition, hardness testing, airtightness testing for high-voltage adapter applications, and microscopy / SEM analysis to inspect weld microstructure for harmful intermetallic compounds.
