The biggest challenge in injection molding is the process of designing a mold. There are almost no limits to your creativity , but you can do the designs in clever and less clever way from a manufacturing point of view. Plastic manufacturers highlight this aspect as the most crucial part of injection molding. There will [...]
The injection molding process does not require mold flow analysis. But maybe it should be, especially considering that it helps predict production problems before production starts. Mold flow analysis software can simulate the injection molding cycle, using specific plastics and part designs. It evaluates the manufacturability of the design before manufacturing the mold. In this [...]
Two of the major disadvantages to injection molding are the high mold costs and large required lead times. Mold is almost a project in and of itself and only one phase of the entire injection molding process.Before you can produce an injection molded part you first have to design and prototype a part (probably via [...]
As time goes by, the bells ring into 2019, we are constantly looking forward to the latest trends, and what will drive the injection business in 2019. […]
Detailed features and complex geometry The injection mold is subjected to extremely high pressures. Therefore, the plastic in the mold exerts more pressure on the mold than other molding processes. […]
The fused materials in the mold cavity restore from viscous and fluid state to glassy state after being cooled. After complete cooling and molding, […]
When the screw stops rotating and moves backward, the mold clamping part begins to work to close the mold and the injection unit subsequently moves forward to make the nozzle and mold spruing gate joint with each other; […]
The improper design for the structure of plastic parts, the incorrect setting of injection molding technical condition, inappropriate design of mold feed system, temperature control system as well as ejector unit etc altogether result in overlarge remnant internal stress inside the products, and accompanied with insufficient rigidity of product structure and delayed treatment for the [...]
The condensed material of sprue sticks to the sprue of molds, which poses difficulty for ejection. […]
1 Use plastics with sound glossiness (such as ABS and PP etc), appropriately add additives which can improve the glossiness of products, and reduce the content of volatiles in raw materials (such as lubricating agent); […]
