Mandrel for bicycle axle

Gate mold: the runner and gate are on the parting line and demoulded together with the product when opening the mold. The design is simple, the processing is easy, and the cost is low. Therefore, many people use the gate system for operation. The plastic mold structure is divided into two parts: moving mold and fixed mold. The moving part along with the injection machine is a moving mold (mostly at the ejection side), and it is generally called a fixed mold when it is not moving at the injection end of the injection machine. Because the fixed mold part of the big nozzle mold is generally composed of two steel plates, it is also called the two plate mold. The two plate die is a simple structure in the large water port die.

Fine nozzle mold: the runner and gate are not on the parting line, and are generally directly on the product. Therefore, a group of nozzle parting lines should be designed. The design is more complex, and the processing is more difficult. Generally, the fine nozzle system should be selected according to the product requirements. The fixed mold part of the fine nozzle mold is generally composed of three steel plates, so it is also called "three plate mold". Three plate die is a simple structure of fine nozzle die.
