Metal machining parts offer a wide range of benefits that cater to the demands of various industries. These advantages enhance efficiency, precision, and reliability in manufacturing processes.
1. High Precision and Repeatability
Metal machining allows for extremely accurate dimension control, ensuring consistent quality across multiple parts. It is particularly suitable for industries requiring strict tolerances, such as aerospace, medical devices, and precision instruments.
2. Diverse Material Options
A wide range of metal materials can be machined, including steel, aluminum, copper, titanium, and their alloys. This material diversity ensures suitability for different industrial applications, from automotive to construction and electronics.
3. Complex Shapes and Structures
With CNC technology, metal machining enables the creation of intricate geometries and complex structures that are difficult to achieve with traditional manufacturing methods. This is ideal for internal cavities or unique part designs.
4. Cost-Effectiveness
For small to medium production volumes, metal machining offers competitive costs, especially for complex parts. Automation in machining processes further boosts efficiency and reduces labor expenses.
Before CNC machining, our DFM optimization engineers will select or recommend suitable materials for you based on the uses and requirements of your plastic prototype parts, reducing costs while meeting your application requirements. All materials will also be tested by a spectral material analyzer before processing to ensure that customers are using real raw materials.
All metal materials are carefully sourced from trusted suppliers we’ve partnered with over the past 15 years. Before production, each material is tested to ensure it meets your specific requirements, guaranteeing reliable performance and quality for your machined metal parts.
We have our own material library with 40+ metal materials in stock. Engineers will conduct a DFM analysis to select suitable materials for you, reducing material costs by 30%.
Own factory and multiple material suppliers with stable prices.
Each material will undergo material testing and a report will be issued.
A team of 6 engineers and VMT technicians with 20 years of experience provide you with help and recommend suitable metal and plastic materials.
What is a Metal Matrix Composite ?
A Metal Matrix Composite is a type of material that combines a metal, such as aluminum or titanium, with a reinforcing component like ceramic particles or fibers. This combination improves the overall strength, heat resistance, and wear performance of the metal, making it ideal for high-performance applications in aerospace, automotive, and industrial engineering.
Which Metals are Magnetic Materials?
Magnetic metals include iron, nickel, and cobalt, as well as many of their alloys. For example, most types of carbon steel are magnetic due to their iron content. Some stainless steels, such as type 430, are also magnetic, while others like type 304 are not. The magnetic properties depend on the metal’s composition and structure.
Does Metal foam Come from Natural Materials?
Metal foam does not originate from natural materials. It is an engineered product created by introducing gas into molten metal or mixing metal with a foaming agent. The result is a porous, lightweight structure with excellent energy absorption and thermal conductivity, often used in automotive, aerospace, and structural applications.
What Materials Cannot be CNC Machined?
Some materials are not suitable for CNC machining due to their physical properties. These include soft, flexible materials like rubber and silicone, which can deform during cutting, and extremely brittle substances like some ceramics, which can crack or shatter. Very soft foams and elastomers may also be difficult to machine accurately.
Is CNC Only for Metal?
CNC machining is not limited to metals. While it is commonly used for aluminum, steel, and titanium, CNC can also be applied to a wide range of non-metal materials such as plastics, wood, composites, and even foams. The key requirement is that the material must be stable and rigid enough to handle the machining process.
