The plastic bobbin mold finds extensive application across numerous industries, including electronics, toys, stationery, hardware, packaging, and printing, among others.

This mold type is primarily utilized for the production of bobbins, which serve as essential tools for winding wires or cables and are integral to various mechanical equipment.
 

Bobbin materials typically consist of ABS, PE, and PP. Polyethylene (PE) exhibits superior chemical resistance and commendable mechanical strength, rendering it suitable for deployment in various severe environmental conditions.
Polypropylene (PP) boasts high rigidity and toughness, is lightweight, and easy to process, making it ideal for the fabrication of I-shaped coils that necessitate enhanced strength.
Acrylonitrile Butadiene Styrene (ABS) is frequently employed in scenarios requiring excellent electrical insulation and weather resistance due to its insulative properties and durability.

For these bobbin materials, P20 steel is commonly selected for the construction of plastic bobbin molds.

Regarding smaller bobbins, molds are typically designed with multiple cavities to enhance production efficiency.
Conversely, for larger bobbins, taking into account machine size and the cost of plastic bobbin molds, it is common practice to produce molds with a single cavity or dual cavities.

As a general rule, cold runner systems are utilized in mold design to reduce costs.
