Common 8 kinds of plastic material characteristics and application scope and main processes

Plastic-Acrylonitrile-Butadiene-Styrene (ABS) Acrylonitrile-butadiene-styrene (ABS) is a thermoplastic synthetic polymer resin. It has a good balance of properties and can be tailored to suit special needs. Its main physical characteristics are: hard and firm. Resin-grade ASS can have bending properties like synthetic rubber (or rubber). Among them, polybutadiene provides good compressive strength, non-crystalline styrene thermoplastics make

The difference and comparison of wire cutting, laser cutting and plasma cutting

Laser cutting processing Optical cutting is the use of a focused high-power-density laser beam to irradiate the workpiece to quickly melt, vaporize, ablate, or reach the ignition point of the irradiated material. At the same time, the molten material is blown away by the high-speed airflow coaxial with the beam to realize the cutting of

16 types of stamping and stretching forming process

Stretching metal forming is a stamping process that uses molds to form flat blanks into open hollow parts. As one of the main metal stamping processes, stretching metal forming is widely used. The drawing process can be used to make cylindrical, rectangular, stepped, spherical, conical, parabolic, and other irregularly shaped thin-walled parts. If it is

Advantages and Disadvantages of Compression Molding

What is Compression Molding? Compression molding is the operation of first putting powdered, granular, or fibrous plastic into the mold cavity at the molding temperature, and then closing the mold to press to shape and solidify it. Compression molding materials include thermosetting plastics, thermoplastics, and rubber materials. Advantages of compression molding (1) In the custom compression molding process,

defects in injection molding products

What are the common defects in injection molding products?

After injection molding, some problems come into being which will affect the assembly efficiency or the performance of the whole machine. Given the certain discrepancy between the defective and the predetermined standard (inspection standards), those parts will not meet the company’s quality requirements. In that case, strengthening the quality awareness training of employees and dealing
