\"plastic<\/span><\/h2>\n

Secondary machining processes follow primary manufacturing methods. Plastic injection molding manufacture utilizes different secondary processes to improve aesthetics, tolerance, dimensional integrity, and surface finish of molded parts. Learning more about the <\/span>different types of secondary machining processes<\/span><\/a> can help you opt for the one that provides optimum features for your product.<\/span><\/p>\n

What secondary processes are used in plastic injection molding?<\/span><\/h2>\n

The types of secondary process that can\u00a0<\/span>follow injection molding include:<\/span><\/p>\n

CNC machining<\/span><\/h3>\n

CNC machining is an automated process <\/span>that controls a range of machinery to produce different prototypes. The machinery includes mills, grinders, turning, and lathes.\u00a0<\/span><\/p>\n

Milling<\/span><\/h3>\n

The <\/span>peripheral or face milling operations<\/span><\/a> feature a cutting tool that <\/span> carves gear teeth, threads, and slots on a workpiece by utilizing multi-point rotary cutters. This process defines features such as holes, slots, contours, and pockets, and is considered a finishing coat.<\/span><\/p>\n

Turning<\/span><\/h3>\n

Turning can be performed automatically or manually. The machine that\u2019s commonly used for this process is the lathe where the workpiece rotates while the cutting tool passes in linear motion, creating a tube-shaped final piece. Lathe allows for high consistency and efficiency. You can program tool movements and speeds into a computer and send them to the machine for completion.<\/span><\/p>\n

Drilling<\/span><\/h3>\n

Drilling is primarily performed utilizing drill presses, but it can also be done on mills and lathes. During the process, a cutter with cutting edges rotates to create holes on a workpiece.<\/span><\/p>\n

Grinding\u00a0<\/span><\/h3>\n

Grinding or surface grinding utilizes a powdered abrasive paste, sheet, belt, or wheel to produce a surface finish of fine tolerance. The process is a highly precise method of tolerance modification.\u00a0<\/span><\/p>\n

Tapping<\/span><\/h3>\n

Tapping creates grooves on the inside of a drilled hole by employing a conical or cylindrical thread-cutting tool. You can program tapping on a Computer Numerical Control (CNC) machine for an easy and highly efficient threading process.<\/span><\/p>\n

Ultrasonic welding<\/span><\/h3>\n

Ultrasonic welding is a technique that locally applies high-frequency ultrasonic vibrations to workpieces that are pressed together and creates a strong weld joint area. The available types of ultrasonic welding joints include step joint, scarf joint, shear joint, groove joint, and tongue joint.\u00a0<\/span><\/p>\n

Conditioning<\/span><\/h3>\n

Conditioning is applied when you need to change a material’s internal structure in order to achieve more favorable properties. You can do this by utilizing mechanical forces, chemicals, or heat.<\/span><\/p>\n

What are the advantages of using secondary machining processes?<\/span><\/h2>\n

Creating a functional and highly precise workpiece requires expertise and attention to detail. Opting for a reliable manufacturer to carry out your project brings many advantages:<\/span><\/p>\n
