What Materials Can Be Used To Manufacture Plastic Pallets？
High Density Polyethylene (HDPE)
HDPE (High-Density Polyethylene) is a thermoplastic polyolefin produced by copolymerizing ethylene. It is a highly crystalline, non-polar thermoplastic resin. In its natural form, HDPE appears milky white and exhibits a certain degree of translucency when viewed in thin sections.
Plastic pallets made from this material not only have good impact resistance, high hardness, and excellent load-bearing capacity, but they are also easy to reprocess with minimal degradation.
They are widely used for stacking multiple layers of goods, ground circulation, forklift handling, and shelving, making them one of the most commonly circulated pallets in use today.
Polypropylene (PP)
PP is a semi-crystalline thermoplastic polymer made by polymerizing propylene monomers. It possesses high impact resistance, strong mechanical toughness, and resistance to various organic solvents as well as acid and alkali corrosion.
Plastic pallets made from this material exhibit good toughness and ductility, along with certain heat resistance and cold resistance capabilities. They are generally used for manufacturing small-sized food pallets.
Linear Low Density Polyethylene（LLDPE）
LLDPE is a copolymer formed by polymerizing ethylene with a small amount of higher α-olefins under the action of a catalyst, suitable for various thermoplastic molding processes with good processability.
Plastic pallets made from this material not only have high strength, good toughness, strong rigidity, heat resistance, cold resistance, and strong acid and alkali resistance, but also exhibit excellent resistance to environmental stress cracking, high tear strength, and resistance to acids, alkalis, and organic solvents.
Manufacturing Processes For Plastic Pallets
The manufacturing of plastic pallets involves several key processes, each offering unique advantages. The two main methods are injection molding and blow molding.
Among these, injection molding and blow molding are the most commonly used due to their efficiency and ability to produce high-quality plastic pallets.
Injection Molding
Injection molding is the most widely used process in plastic pallet manufacturing. This method allows for precise control over the dimensions and structure of the pallet, making it ideal for producing high-precision, complex designs.
The versatility of injection molding enables the production of pallets with various surface textures and bottom structures, such as flat，grid，stringer and nine-leg designs.
For instance, injection-molded pallets are favored for heavy-duty applications in industries like automotive and construction due to their high load capacity and durability.
The drawback of injection-molded pallets is the high initial cost, as the investment in injection molds and equipment is substantial. Additionally, once the plastic pallet mold is customized, it is difficult to change the design, and the cost of iteration is high.
Blow Molding
Blow molding, also known as hollow blow molding, involves extruding molten plastic into a tubular form, which is then placed into a mold and inflated using high-pressure air to form the pallet. This process is particularly effective for creating hollow, double-sided pallets that excel in load-bearing capacity and impact resistance. Common designs include blow-molded nine-leg and double-sided pallets.
While blow-molded pallets offer excellent durability, they do have some limitations. They cannot incorporate internal steel reinforcements, which may make them less suitable for certain racking applications. Despite this, blow molding remains a popular choice for producing durable plastic pallets with impressive structural integrity and resilience.
Structural Design Principles Of Plastic Pallets
The structural design of plastic pallets is crucial for ensuring their performance and compatibility with various logistics and storage systems.
The dimensions and shapes of plastic pallets should adhere to international or domestic standards, such as 1200mm×1000mm or 1100mm×1100mm, to ensure seamless integration with automated storage and retrieval systems.
Controlling the dimensional tolerance within ±3mm is essential for stable operation and precise positioning in conveyor and racking systems.
Plastic pallets must be designed to accommodate both static and dynamic loads. Static load capacity depends on the specific application, ranging from around 1 ton for light goods storage to 5 tons or more for heavy machinery parts.
Dynamic load capacity is typically 50% to 70% of the static load capacity to ensure reliability during frequent handling operations. The structural design should balance strength and weight, with common configurations including stringer, perimeter, and nine-leg designs.
Additionally, the design must consider load stability. Features such as rims, anti-slip surfaces, and interlocking mechanisms help secure goods during transport and storage, preventing slippage and enhancing safety.
These design principles ensure plastic pallets remain durable and effective across applications like warehousing and transportation.
Quality Control And Equipment Requirements In Plastic Pallet Manufacturing
In the realm of plastic pallet manufacturing, advanced production equipment and technology are fundamental to maintaining market competitiveness and ensuring product quality.
High-performance injection molding machines play a central role, with their injection pressure, speed, and temperature control parameters directly impacting the flow and filling of the plastic melt.
Precise adjustment of these parameters results in uniformly structured pallets without bubbles or shrinkage, significantly enhancing overall strength and durability.
Beyond the core equipment like injection and extrusion machines, the integration of automated production lines has revolutionized plastic pallet manufacturing.
These automated lines encompass raw material pre-treatment, molding, post-processing, and quality inspection, enabling continuous and intelligent production.
Automation minimizes human error and variability, ensuring consistent product quality and stability. It also boosts production efficiency and reduces costs, with some reports indicating a 3-5 fold increase in efficiency and a 40%-50% reduction in labor costs.
Automated systems can also monitor equipment status and product quality parameters in real-time, issuing alerts and adjustments when anomalies are detected.
This proactive approach effectively prevents the production of defective products and enhances overall manufacturing reliability.
