Injection Molding Process of Cable Tie Pads

Cable tie pads are made by injection molding process. Standard cable tie uses nylon 66 as raw material. In this process, nylon 66 pellets are loaded into an injection molding machine, which is usually heated to a molten state. After the nylon 66 material is melted by pressure, it is injected into a steel mold with a large number of cavities formed in the form of cable tie pads.


The individual plastic molds are grouped side by side to create a batch of cable tie pads in a single stroke of melt injection. After a while, the finished cable tie pads can be taken out of the steel mold, adjusted and packed for transportation. Cable tie pads are usually produced in batches, and the quantity depends on the size. If the cable tie size is smaller, there will be many cable ties in a batch.


When the cable tie pads are produced, some identification marks are attached to each mold. In some cases, the label can be numbers, letters or logos. These marks come in handy when quality control begins to eliminate defects or blockages or identify defects in the mold cavity.


In the process of producing cable ties such as 370 x 4.8 mm, some molds will appear in the mold cavity, resulting in some cable ties every time plastic is injected. If a cavity marked AZ is used, a continuous cable tie marked AZ will be produced.


Usually, spare molds are created to replace defective molds found during quality control.


The design and shape of the cable tie pads depends on the size and shape of the cavity used in the production process. Each has different ways to achieve a unique shape, color and length of cable tie. The manufacturing process must also minimize micro-marking in the manufacturing process. These may include streaks, protrusions, and dents. These streaks are caused by subtle irregularities in the mold cavity and the pins used to remove the cable tie from the cavity.
