State-of-the-Art Plastic Pallet Box Factory Tour: Quality and Efficiency Guaranteed
Leave a message
Introduction
A plastic pallet box is a large loading and turnover container developed based on a plastic pallet. Its foldable and stackable design helps save space and improve storage efficiency. It is widely used for the packaging, storage, and transportation of various parts and industrial products, making it one of the most versatile logistics containers.
In this article, we will guide you through how a reliable plastic pallet box factory operates - from raw material selection and production processes to strict quality control - ensuring that every pallet box meets high industry standards.
Plastic Pallet Box Manufacturing Process
Raw Material Preparation
The main raw materials used in the production of plastic pallet boxes are food-grade HDPE (High-Density Polyethylene) or PP (Polypropylene) resin pellets. These materials have excellent impact resistance, stable chemical properties, and are recyclable, making them ideal for manufacturing plastic pallet boxes.
Material Blending and Coloring
Plastic pallet box manufacturers generally mix color masterbatch and UV stabilizers with the raw resin according to customer requirements. This ensures consistent color in the finished plastic pallet boxes and provides effective UV protection, which is especially important for users who need to use them outdoors.
Injection Molding or Blow Molding
After all the raw materials are mixed, they are fed into large injection molding or blow molding machines. The injection molding process is typically used to produce plastic pallet boxes with thicker walls, such as industrial pallet boxes, vented bulk containers, and rigid pallet boxes.
Blow molding, on the other hand, is mainly used to manufacture lighter or hollow-structured pallet boxes, such as dry ice boxes.
During the molding process, the molten plastic is injected into the mold cavity under high pressure and then cooled to form the shape of the pallet box. This process ensures the structural integrity, strength, and stacking performance of the plastic pallet boxes. Generally, the dynamic load capacity of a plastic pallet box is around 1T, the static load capacity is about 4T, and they can be stacked in 4 to 6 layers.
Demolding & Trimming
After molding, the plastic pallet boxes need to be cooled first to stabilize their shape before being demolded. To prevent deformation, they are usually allowed to cool for a period of time before any trimming is done. Demolded plastic pallet boxes often have some edge burrs or excess plastic. Workers trim the burrs, polish the vent holes to make the edges smooth, and inspect the appearance of the plastic pallet boxes, checking for visible defects, scratches, or dents.
Secondary Processing
After the initial trimming, plastic pallet box suppliers may perform functional and customized modifications to the molded boxes based on customer requirements or specific application scenarios. For example, they may add casters to the bottom of the pallet boxes for easier handling and transportation, or install lids or side panels to make loading and unloading goods more convenient.
Printing
Plastic pallet box manufacturers can also screen print or spray code on the pallet boxes according to customer requirements to mark the customer's brand, model and batch.
Quality Testing of Plastic Pallet Boxes
Generally, before the product is shipped, the manufacturer will also conduct a series of quality inspections on the product, mainly in the following three aspects:
Visual Inspection
A professional quality inspection team will conduct an appearance inspection on the finished plastic pallet boxes, such as checking whether there are bubbles, cracks, burrs, whether the color is uniform, whether the plastic pallet boxes are deformed, and whether the printed customer logo is clear.
Dimensional & Tolerance Check
Quality inspectors also use calipers or coordinate measuring machines (CMM) to conduct random checks on the dimensions of the plastic pallet boxes. They measure the length, width, and height to ensure they meet customer requirements, as well as the wall and bottom thickness, ensuring the products remain stable when stacked and comply with the standard volume specifications.
Load & Compression Test
The static load capacity of plastic pallet boxes is generally 4 tons, while the dynamic load capacity is 1 ton. The quality inspection team usually tests the boxes under static, dynamic, and stacking conditions.
• Static load test:
Tests the weight the pallet box can withstand under normal stacking conditions.
• Dynamic compression test:
Simulates handling, collisions, and impacts during transportation of plastic pallet boxes.
• Stacking test:
Checks whether the plastic pallet box with lid deform or break when stacked in multiple layers.
