Special Machines Are Required In The Cable Tie Production Process
The most recent updates are all about the production process of stainless steel twist ties. Next, let's take a look at why special machines are needed in the production process of cable ties with metal lock?
The nature of metal cable zip ties requires this
All multi-purpose black stainless steel cable ties tend to be longer, narrower and thinner. They come in a variety of lengths, widths and different strengths.
Successful molding is a complex process
When the molten nylon 66 is poured into the mold cavity, the machine must push the nylon material from top to bottom in a very short time to avoid freezing midway.
Pressure is required
When the molten material is pushed into the mold cavity, the process requires a high injection speed and pressure. This force is naturally transmitted to the clamping device on the machine. If the force is not enough, the mold can be blown open.
The cable tie mold cavity is long and narrow
The fact that the mold cavity is long and narrow means that the unique design of the toggle and the entire clamping structure will be used to concentrate the force in the center of the moving platen. In case the toggle and clamping device cannot move the platen as required, the mold will have problems due to uneven force.
Injection speed needs to be high
There are custom-made molding machines that can increase the injection pressure and injection speed by increasing the capacity of the pump and motor. This helps to fill the cavity quickly for successful molding. Nevertheless, the impact on the toggle will be greater with each injection and clamping, and the same force will be transmitted to the clamping unit. If these components are not ready to absorb the pressure, they will wear out quickly.
Mass production
Also, the reason why injection molding requires special equipment is that the process is mainly used for mass production. The metal tooth cable ties alone is not worth the process. The energy required to prepare the plastic and press it into the mold cavity, as well as to keep the mold clamped, is very high. For this reason, it is cost-effective to mold many parts in tandem.
The most special aspect of the cable tie injection machine is the molding tool. However, there are often problems in bringing the molten plastic to all parts of the mold before it starts to deteriorate. This is usually solved by gating. Some molding machines use hot runners to prevent the plastic from freezing or hardening in the cavity.
