What processing techniques are available for Tailor-Made Metal Parts?

In the research and development of industrial production and product innovation, Tailor-Made Metal Parts are everywhere.As small as the core components in precision instruments, to the key structure of heavy equipment, its performance, precision and reliability directly determines the quality of the final product.In the face of various design requirements, material properties and application scenario, how to choose the suitable processing technology, become to realize the design idea, control cost and guarantee delivery of a key step.In this article, we will for your system carding mainstream custom metal parts processing technology, help you to find the optimal solution in the many choices.
I. Subtractive Manufacturing: Traditional and CNC Cutting Processing
This type of process achieves the desired shape and size by removing excess materials and is the most widely used and technologically mature processing method.

Principle: By using a high-speed rotating multi-edge cutting tool to cut a fixed workpiece, it can process planes, grooves, curved surfaces and complex three-dimensional contours.

Features: Extremely high flexibility, suitable for a wide range of materials from aluminum, steel to titanium alloys.Multi-axis linkage CNC milling machine (such as three axis, four axis and 5 axis) be able to complete the many facets of the complex parts processing, one-time improved accuracy and efficiency, is the processing box, shell, the core of the mould and profiled.

Principle: The workpiece rotates, and the cutting tool moves axially or radially for cutting. It is mainly used for processing rotary parts.

Features: High processing efficiency, good dimensional accuracy and surface finish.Applicable to the shaft, rod, cover, plate, flange, etc.Car milling compound center to integrate the function of turning and milling, which can realize more complex composite processing, reduce the number of the clamping, improve the overall accuracy.

As a key hole machining process, often used with milling, turning, is used to create accurate hole, thread and inner cavity finishing.
Ii. Forming and Deformation Processing
Such process by making the occurred plastic deformation metal materials to obtain the required shape, usually applies to have certain specific parts of the batch.

Principle: Pressure is applied to the sheet metal by using molds and stamping equipment to cause it to separate or undergo plastic deformation.

Features: Extremely high efficiency, low unit cost after cost allocation, and good consistency.Suitable for production of sheet metal parts, such as shell, connector, terminal structure relatively fixed thin wall parts.From simple to complex blanking, punching the tensile, bending can be implemented.

Principle: Molten metal is poured into a prefabricated cavity, and after cooling and solidification, it takes shape.

Features: It can produce blanks with extremely complex shapes, especially those with complex inner cavities (such as engine blocks, valve bodies, and artworks).Commonly used technologies include sand casting, precision casting, lost wax method), die casting, etc.Casting often requires subsequent cutting to achieve accurate dimensions.
Iii. Special Processing and Additive Manufacturing
This type of process offers unique solutions for high-hardness, high-complexity or extremely small-batch prototypes.

Principle: Conductive materials are processed by the electrical erosion effect generated by pulse discharge between the two poles.

Features: "Softness overcomes hardness", capable of processing any high-hardness and high-strength conductive materials (such as quenched steel, hard alloys).Especially good at processing complex mold cavity, deep groove, narrow seam and micro-hole, high precision.

Principle: It is a type of electrical discharge machining that uses a continuously moving metal wire as an electrode for cutting.

Features: Mainly used for precise blanking of two-dimensional contours, it can cut out extremely complex pattern flat plate parts, with narrow cutting edges and high material utilization rate.Slow wire cutting can achieve higher precision and finish.

Principle: Use high-energy-density laser beams to cut, weld or treat the surface of materials.

Features: High cutting accuracy, small heat-affected zone, narrow cutting seam, suitable for precise cutting of various metal plates.Laser welding can realize the precise connection with large depth to width ratio and small deformation.
Metal 3D printing (metal additive manufacturing

Principle: Parts are directly manufactured by layer-by-layer stacking of metal powders (such as SLM selective laser melting) or metal wires (such as DED directed energy deposition).

Features: The highest℃of design freedom, capable of forming almost any complex geometric shape (such as topologically optimized structure, integrated internal flow channels, conformal cooling water channels), achieving lightweight and functional integration.Especially suitable for the aerospace, medical implants, small batch complex mold and rapid prototyping.Although the cost of equipment and materials is high, it is a revolutionary choice for complex structures that are beyond the reach of traditional processes.
Iv. Surface Treatment and Post-treatment
Processed and formed parts often require post-treatment to enhance their performance and appearance:

Mechanical treatment: sandblasting, polishing, and brushing to improve appearance and feel.

Heat treatment: quenching, tempering, carburizing, etc., to enhance the hardness, strength or wear resistance of parts.

Surface coating: electroplating (chromium plating, nickel plating), electroless plating, anodizing (for aluminum), blackening, spraying, etc., endowing parts with anti-corrosion, wear resistance, aesthetic appeal or special functionality.

When faced with numerous processes, the choice is not a single one but often a combination.Qingdao Ruixin Yang Machinery Co., Ltd. suggests that you make a comprehensive evaluation from the following dimensions:
Part geometric complexity: Preferred turning for simple rotary bodies;Complex 3D surfaces rely on multi-axis milling or 3D printing.Complex two-dimensional plate parts optional laser cutting or cutting;Blanks with complex cavities can be considered for casting.
Material properties: Die steel with extremely high hardness, is preferred for electrical discharge machining;For complex parts with superalloys, 3D printing may be more economical.
Batch size and cost: For large-scale standard parts, the cost advantage of stamping and casting molds is obvious.Small batch, many varieties, or prototype parts, CNC cutting flexible is better;A single piece is extremely complex, and 3D printing may save the overall cost.
Precision and surface quality requirements: High-precision mating surfaces need to be finely ground or precisely machined.The decorative appearance needs a fine finish or special coating.
Delivery cycle: Rapid prototyping can focus on 3D printing or rapid CNC machining.Standard process chain is more stable and reliable.
