The checking points for mold flash part Apr 12, 2019
It's very common to see some flashes on the part during mold testing. Today we are going to discuss some check points when we get flashed parts. 1. Mold fitting 2. Parting Line (PL) problem (1) Check if the surface of the core is higher than the surface of the AB plate (about 0.5MM) (2) Check the flatness of the surface to see if it is deformed because the mold plate is too thin. (3) Is there any ...

Mold Texture Discussion Apr 12, 2019
Texture is a common process for mold surface treatment, which directly affects the appearance and surface strength of the product surface. Mold texture, also known as mold etching, mold graning, is widely used due to its low process cost, rich effect and fast speed. It's use chemical liquid (such as sulfuric acid, nitric acid, etc.) to chemically react with the mold steel, and the reaction p...

The advantages for Hot Runner Mold Apr 22, 2019
The hot runner mold refers to a mold that uses a heating device to keep the melt in the flow passage from solidifying at all times. Because it is shorter than the traditional mold shot cycle and saves raw materials, hot runner molds are widely used in various industrialized countries and regions in the world today. Shorten cycle The molding cycle is shortened. Because there is no restriction on th...

Injection Mold Cooling Water Leakage Failure and Troubleshooting Apr 22, 2019
Injection mold cooling water leakage is a frequent occurrence, for many reasons, mainly in the following aspects: 1. The most occurs at the joint of the mold cooling water pipe. If water leakage is found, the sealing tape should be wound around the thread of the pipe joint and then tightened. 2. Due to long-term molding conditions, the waterproof ring inside the mold will be damaged, and the O-sha...
Preparations Before Mold Trial Apr 26, 2019
Mold trial is an essential part of the new mold before injection production, The quality of the test results will directly affect whether the subsequent production of the factory is smooth. What precautions should be paid attention to when test the mold? 1. Familar with the relevant information of the mold It is better to get the mold drawing, analyze it in detail, and get the mold technician to p...

Cooling System in Injection Molding (1) Apr 26, 2019
The design of cooling system is very important in injection moulding. This is because only when the plastic parts are cooled and solidified to a certain hardness, can the plastic parts be avoided from deformation due to external force after demoulding. Because the cooling time accounts for about 70% - 80% of the whole cycling time in moulding, a well-designed cooling system can greatly short...

The program control of injection speed Apr 26, 2019
The program control of the injection speed is to divide the injection stroke of the screw into 3 to 4 stages, and each of the stages uses an appropriate injection speed. For example, when the molten plastic just starts to pass through the gate, the injection speed is slowed down, and during the filling process, high-speed injection is used, and the speed is slowed down at the end of filling. With ...
