Cutting Parts
Cutting parts is a common process in manufacturing industries, used to cut raw materials such as metal, plastic, etc., into specific dimensions and shapes to meet the requirements of product design. This process can employ various tools and equipment such as knives, steel dies, CNC machines, laser cutting, etc., selecting the appropriate cutting method based on the material's characteristics and manufacturing requirements. The accuracy and quality of cutting parts are crucial for the manufacturing process and product performance, thus requiring precise planning and operation. This process finds widespread applications across various industries including automotive manufacturing, aerospace, construction, furniture manufacturing, etc. Through cutting parts, raw materials can be effectively transformed into various components and parts used in the production of various products.
Die Cutting
Die cutting is a common manufacturing process used to cut materials into desired shapes and sizes. Die cutting typically employs either knife dies or steel rule dies, each with its own characteristics.
Knife Die: A knife die is a type of die with lower precision but lower cost. It consists of blades that can be shaped and sized as needed. During the die cutting process, the material is placed on the knife die and then cut. Knife dies are commonly used for producing smaller volume and simpler shaped parts, such as paper sheets, plastic pieces, etc.
Steel Rule Die: Steel rule die, on the other hand, is a type of die with higher precision and longer lifespan. It is made of hard metal, typically steel, capable of withstanding high pressure and temperature. Steel rule dies are usually employed for producing larger volume or more complex shaped parts, such as automotive body parts, electronic product casings, etc.
Die cutting processes find wide applications across various industries including packaging, printing, automotive, electronics, etc. It efficiently produces large quantities of identical shaped parts at lower costs. However, for parts with complex shapes or requiring high precision, the use of steel rule dies may be necessary.
Laser Cutting
Laser Cutting (also known as Laser Cutting) is a high-precision manufacturing process that utilizes a laser beam for cutting. During the laser cutting process, a high-energy-density laser beam is focused on the workpiece, heating it locally to the melting point or vaporization point, thereby achieving cutting.
Laser cutting offers the following advantages:
- High precision: Laser cutting can achieve extremely precise cutting, with accuracies reaching tens of micrometers, making it suitable for manufacturing precision parts.
- Non-contact: The laser beam in the laser cutting process does not touch the workpiece surface, thus avoiding surface damage or deformation.
- High speed: Laser cutting is fast, enabling mass production.
Laser cutting finds extensive applications in cutting various materials, including metals, plastics, glass, fabrics, etc. It is widely used in industries such as automotive manufacturing, aerospace, electronics, jewelry, etc.
CNC
CNC (Computer Numerical Control) is an automated manufacturing technology that utilizes computer-controlled numerical instructions to manipulate machine tools or robots for machining operations. CNC technology can be applied to various machining processes, including milling, turning, drilling, and engraving.
The primary features of CNC technology include:
- High precision: The computer-controlled machining process can achieve high-precision machining, improving product quality and consistency.
- Flexibility: By modifying machining programs or changing tools, CNC machines can achieve machining of different shapes and sizes, enhancing production flexibility.
- Automation: The CNC machining process is controlled by computers, enabling automated production and reducing manual operation.
CNC technology finds widespread applications in various sectors of the manufacturing industry, including automotive manufacturing, aerospace, medical devices, mold making, etc. It can process a variety of materials, including metals, plastics, wood, etc., with a wide range of applications and high efficiency.
