Common reasons for the temperature rise of TPE injection molding machines include the following: (1) The volume of the oil tank of the  injection molding  machine is too small, the heat dissipation area is insufficient, and the cooling device has a small capacity. (2) The fixed pump oil supply system that selects the oil pump capacity according to the fast forward speed, the excess flow will return from the relief valve under high pressure and generate heat during work. (3) The unloading circuit in the system fails or because the unloading circuit is not set, the oil pump cannot be unloaded when it stops working, and the entire flow of the pump overflows under high pressure. Overflow loss occurs and heat is generated, resulting in excessive temperature. (4) The system piping is too thin and long, too much bending, local pressure loss and pressure loss along the process are large. (5) Insufficient component accuracy and poor assembly quality, and large mechanical fric

The processing of metallic plates is sheet metal processing. For example, using sheet materials can be processed into products of various shapes such as chimneys, iron barrels, oil pots, etc. as we know. Sheet metal processing is more and more favored by users. It will evolve the shells we used to make from plastic through the special processing methods of sheet metal to evolve into sheet metal. This way, the processed products are stronger than before. Good, and long use time. Sheet metal processing methods include: non-mold processing and mold processing. Although their processing processes are similar, they can't escape the following points. Let's talk about the processing steps of sheet metal processing: 1. The design department designed the parts and components pictures according to the requirements, and developed them one by one in 3D to facilitate the processing department's processing, and fully demonstrated the specific structure of the sheet metal parts

What is forging? Upset forging: A method of forming and processing plastic parts, including workpieces, tools, or blanks, by applying external force to metal blanks (excluding plates) to cause plastic deformation, change size, shape, and improve performance. Types and characteristics of  steel forging When the temperature exceeds 300-400 ℃ (blue brittle zone of steel) and reaches 700-800 ℃, the deformation resistance will decrease sharply and the deformation energy will be greatly improved. According to the forging performed in different temperature regions, according to the different forging quality and forging process requirements, it can be divided into three forming temperature regions: cold forging, warm forging, and hot forging. Originally, there was no strict limit on the division of this temperature region. Generally speaking, forging in a temperature region with recrystallization is called hot forging, and forging without heating at room temperature is called c
