The plastic pallet mold is important for industrial applications, especially when transporting industrial products in containers. The main material used for manufacturing plastic pallets is recycled plastic. Injection molding of large-sized pallets requires a large-scale injection mold. It also requires a filling gate to reduce welding lines and enhance structural strength.
The cooling channel temperature is set to 20 degC. It was run for 20 cycles. The temperature of the mold plate reached a steady-state after 20 cycles. The temperature of the core and cavity was measured using a K-type thermocouple. However, the temperature of these two parts was higher than the temperature of the cooling channel. Therefore, the heat transfer was inefficient.
The process of creating plastic pallets entails biaxial rotation. The mold maker uses controlled temperature to fill the molds with polyethylene. Different types of polyethylene are used, including cross-density polyethylene, high-density polyethylene, and linear low-density polyethylene.
The plastic pallet product is a large, heavy package. As a result, there are several challenges in filling it. The multi-point gate must be designed using CAE because defects and weld lines can affect the strength of the plastic pallet. Also, the pallet mold may need a hot runner to prevent material leakage.
A sequential valve gate system can be used to mold a polypropylene pallet. The results of this study revealed that the sequential valve gate system produces fewer welding lines in the plastic pallet mold than the concurrent valve gate opening scheme. This was based on numerical simulation of the process using twelve gates.
A plastic pallet is a durable and long-lasting piece of packaging. Unlike wooden pallets, plastic pallets can be re-used many times throughout their supply chain. This makes them a more sustainable option than their wooden counterparts. Furthermore, they can withstand multiple shipping cycles and long service times.
An injection molding simulation is a crucial step in optimizing the plastic pallet molding process. A proper simulation will identify any weaknesses in the molded components and correct these issues. When using a simulation tool, remember to take the material strength and the plastic pallet shape into account. For example, if you have a high load to lift, you should consider using multiple injection gates for the best results.
A rotational molded plastic pallet can be very durable and lightweight. This allows for easy customization and modification. It also reduces the risk of plastic pallet shortage. It also offers flexibility, as you can change molds easily if necessary.
