Metal Fabrication
CNC Machining
WHAT IS CNC machining?
Cofan’s CNC (Computer Numerical Control) machining is a process where computer software controls the movement of factory tools and machinery like grinders, lathes, mills, and routers. The process starts with a CAD (Computer-Aided Design) model, converted into G-code via CAM (Computer-Aided Manufacturing) software. This G-code instructs the machine on speed, feed rate, and coordination.
The workpiece, which can be metal, plastic, wood, or other materials, is placed in the CNC machine. The machine then performs precise cutting, drilling, milling, or other operations in multiple axes (X, Y, Z) to create complex shapes. Post-machining processes like deburring, polishing, or coating may follow.
The advantages of CNC machining include high precision, efficiency, versatility, and the ability to create complex geometries. It is used in automotive, aerospace, medical, electronics, and prototyping industries for producing engine components, high-precision parts, medical devices, housings, connectors, and prototypes.
Die Casting
WHAT IS die casting?
There are two methods: hot-chamber (for low melting point metals like zinc and magnesium) and cold-chamber (for higher melting point metals like aluminum). Die casting offers high production rates, precise parts, and the ability to produce complex shapes. It’s widely used in automotive, aerospace, electronics, and consumer goods industries for items like engine components, electronic housings, and hardware fittings.
Extrusion
WHAT IS extrusion?
Cofan’s extrusion is a manufacturing process that shapes materials like metal, plastic, or ceramic by pushing or drawing them through a die. Heated if necessary, the material is forced through the die to form the desired profile. This process can be continuous for long lengths or semi-continuous for multiple pieces.
Extrusion allows for the creation of complex cross-sectional shapes, offering high production rates and efficient material use. It’s commonly used for producing pipes, tubes, sheets, and structural components in industries like construction, automotive, and aerospace. The process is versatile, working with various materials and ensuring consistent quality and accuracy.
Plastic Injection Molding
WHAT IS plastic injection molding?
Cofan’s plastic injection molding efficiently produces large volumes of precise, consistent plastic parts. The process starts with plastic pellets melted in a heated barrel. The molten plastic is injected under high pressure into a mold cavity that shapes the part. Once the plastic cools and solidifies, the mold opens, ejects the part, and the cycle repeats quickly.
Advantages include high precision, repeatability, and the ability to create intricate designs and complex geometries. It works with various materials, including thermoplastics, thermosetting plastics, and elastomers. Applications span industries such as automotive (dashboards, bumpers), consumer goods (toothbrushes, toys), electronics (housings, connectors), and medical (devices, components).
Sheet Metal Production
WHAT IS sheet metal?
Cofan’s sheet metal is a thin, flat material used in metalworking, available in various thicknesses and made from materials like steel, aluminum, copper, brass, and tin. Each type offers unique properties: cold rolled steel for precision, hot rolled steel for construction, galvanized steel for corrosion resistance, and stainless steel for rust resistance.
Applications include automotive and aerospace (body panels, engine components), construction (roofing, ductwork), consumer goods (appliances, electronic enclosures), industrial (machinery housings, HVAC systems), and art and design (sculptures, furniture).
Fabrication techniques involve cutting, bending, punching, forming, and joining. Sheet metal’s advantages include versatility, strength, durability, cost-effectiveness, and recyclability, making it essential in modern manufacturing and construction.
