Plastic mold injection molding method of rotational molding

Plastic mold injection molding method of rotational molding

Rotational molding, also known as rotational molding, is a processing method used to manufacture hollow seamless products of various sizes and shapes. Traditionally, it is mainly used in thermoplastic materials. In recent years, the rotomolding of thermosetting materials such as cross-linkable polyethylene has also developed rapidly. Because rotomoulding does not require higher injection pressures, higher shear rates or precise compound gauges. Therefore, the mold and the machine are relatively inexpensive, and the service life is longer. Its main advantages are: the performance/price of the machine is relatively high; the molding of complex parts does not require post-assembly; multiple products and multiple colors can be molded at the same time; the cost of the mold is low; the color and material are easy to change; the loss of scrap is low.

Basic knowledge of die casting

Basic knowledge of die casting

In die casting, the process of filling the cavity with metal is to apply pressure. Speed. Temperature. And time and other process parameters to be unified. At the same time. These process parameters influence each other. mutual restraint. And complement each other, only the correct selection and adjustment of these parameters. Make it coherent. to get the desired effect. Therefore. In the die casting process. Not only should pay attention to the process of casting structure. The advanced nature of the mold, the excellent performance and structure of the die-casting machine, the adaptability of the selection of die-casting alloys and the standardization of the melting process. More attention should be paid. Pressure. Speed. Temperature. The important role of process parameters such as time and time on the quality of castings.

Common Die Steel Model

Common Die Steel Model

The material selection of the mold is good or not, which directly affects the manufacturing cycle of the product, that is, the number of mold openings, and also affects the surface treatment process of the product. Some materials cannot be treated with specular highlights, while others have weak strength and are not suitable for insertion.
