Plastic bobbin mold is the most common type of injection mold for manufacturing plastic bobbins, which is widely used in textile and wire & cable industries. The mold has an integrated design with an iron spool built into the center hole, and is usually made of ABS, PS, PP and other raw materials with excellent balance. These spools make the winding, unwinding and transportation of cables, wires and other products easier and more efficient. Next, we will have a more in-depth discussion on plastic spool molds.
The main features of plastic swing reel production line
1. Standard plastic spools and reels are widely used in the production and transportation of wire and cable, fiber optic cable, copper wire and core wire, in addition to other types of steel wire rope. The materials used are mainly ABS injection molded plastic or HIPS.
2. These reels have excellent balancing properties, high strength, impact resistance, and resistance to acid and alkali corrosion, and their accuracy can reach grade 6.3 or higher.
3. These reels can be reused during the production process. A wide range of equipment is suitable, including single stranders, twisting machines, high stranders, take-ups, extruders, winding machines and knitting machines, etc.
In addition, plastic reels and spools are generally made of ABS or HIPS, while turnaround plastic reels are mainly packaged in new ABS and PS materials. When using swing reels, it is especially important to know their exact specifications. Where conditions permit, it is recommended to try to use the national standard products, because of its universal applicability, rich inventory, and can effectively save time and labor costs.
Compnents of plastic spool mold
The design phase of a mold is an important part of determining the shape, dimensions and features of the spool. This process is often performed with the aid of computer-aided design (CAD) software to achieve precise control over the design.
First, the size and layout of the plastic bobbin needs to be considered in depth. This is based on the specific application scenario and the size and shape of the spool required in relation to the size of the cable or wire being wrapped around it. Next, key factors such as the diameter, width and flange size of the spool should be evaluated to ensure that it can effectively carry the required length of cable and provide adequate support during winding and unwinding.
Next, the strength and durability of the finished product is significantly influenced by the core and cavity design. At this stage, an accurate core and cavity design is created, taking into account the draft angle and ejection structure to accurately reproduce the desired bobbin shape.At the same time, the shrinkage of the material during the molding process is taken into account and appropriate allowances are made in the mold design to ensure that the dimensions of the final molded product are as expected.
Finally, the gate and sprue design in plastic bobbin molds is a core factor in the quality and efficiency of the injection molding process. In the design stage, the optimal gate and sprue system should be determined to promote the smooth flow and reasonable distribution of material in the mold, and strive to minimize the defects of the final molded bobbin.
