The rubber compression molding process begin with filling the rubber compound into the cavity of a metal mold and vulcanizing it into a silicone product. However, due to the residual air and vulcanization gas in the cavity, the structure of the mold must be able to eliminate the residual gas through the pressure formed by

Poor gloss means that the surface is dim and has no gloss, and the transparency of transparent products is low. There are many reasons for poor gloss. Other injection defects are also the cause of poor gloss. 1. Mold failure Since the surface of the plastic part is a reproduction of the mold cavity surface,

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
Surface treatment is to form a layer with one or more special properties on the surface of the material through physical or chemical methods. Surface treatment can improve product appearance, texture, function and other aspects of performance. You can also check on more details in the electroplating surface finish. 1. Anodizing It is mainly the anodization

1. What is the effect of the deep sill (drawing rib) in the cover mold? The effects of the deep drawing threshold (drawing bead) are as follows: 1. Increase the friction resistance of the feed material, so that the surface of the deep drawing part bears sufficient tensile stress, improve the bending stiffness of the

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

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

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 In the custom compression molding process,
