The Process of Key Role for Warehousing: Plastic Pallet Injection Molding

2023-08-02 16:43:17

In logistics and warehouse management, pallets are common and crucial tools used for convenient stacking of goods, optimizing storage space, and facilitating safe transportation and storage. They protect goods from ground moisture, dust, pollution, and other damages. Pallets are typically made from wood or plastic, and compared to traditional wooden pallets, plastic pallets offer advantages such as being lightweight, durable, easy to clean, safe without splinters, and recyclable.

But have you ever wondered how plastic pallets are manufactured? In this article, we will take you into the world of injection molding, where you'll discover the process of manufacturing plastic pallets through injection molding technology, ultimately transforming into essential tools in warehouse management, and what factors must be considered for a suitable plastic pallet injection molding machine.


Overview of the injection molding process of plastic pallets

Injection molding is a widely used manufacturing method for producing plastic products, including plastic pallets. The process involves injecting molten plastic material into a mold cavity through the screw, allowing it to cool and solidify, and then ejecting the finished product. The injection molding process consists of several steps, each crucial in ensuring the final product's quality and functionality.

Materials of Plastic Pallets

Plastic pallets are primarily made from two materials: High-Density Polyethylene (HDPE) and Polypropylene (PP). HDPE pallets offer durability and affordability, while PP pallets are rigid and suitable for high-temperature applications.



Choosing the right injection molding machine for plastic pallet production

Selecting the appropriate injection molding machine is crucial for the efficient and successful production of plastic pallets. According to the size, thickness, plastic fluidity, etc. of the product, the mold and injection molding machine also need to be configured accordingly. For plastic products as large as pallets, the mold and injection molding machine are also quite huge. Several factors need to be considered when choosing the right injection molding machine for plastic pallets. Let’s find out:

One important consideration is the clamping force of the machine. The clamping force determines the maximum force that the machine can apply to keep the mold closed during the injection process. Plastic pallets are relatively large and require a significant clamping force to ensure proper molding. Therefore, a machine with a high clamping force is necessary to produce plastic pallets efficiently. In the experience of the pallet injection molding machine provided by Huarong, the pallet size is 1000 in length, 1200 in width and 150 in height (mm), the machine clamping force is 2400 tons, and the overall length of the machine is 22 meters. With the quick mold change system, it saves the loading and unloading time of large molds.

Another consideration is the plasticizing ability of injection unit, including the shot weight, injection pressure, and injection rate. Plastic pallets have a larger volume compared to other plastic products, so an injection molding machine with a sufficient plasticizing ability is essential to avoid incomplete injection and ensure consistent quality.

Additionally, the machine's power system and automation integration should be evaluated. The power system will affect the injection pressure and injection rate, and advanced power systems can optimize the injection molding process by precisely controlling, resulting in more accurate and consistent pallet production. Automation integration, such as robot arm, can save labor costs, and enhance production competitiveness.
