What is a Pallet Bin?
A pallet bin or bulk bin or plastic pallet container is a portable, rigid and reusable industrial storage and transport container used to handle heavy or bulky raw materials and finished components. Pallet bins are designed with a view to ensure proper space utilization of return trucks that return without carrying any loads. A pallet bin typically has a load-holding base so forks can lift it from all four directions using forklift trucks (or electric stacker or hand-guided truck) and conveyance it in trains etc.
Pallet Bins as an industry segment grew out of modern supply chain needs of use of gloves by human workers while handling raw components possible only if supplied in large quantities at one go (so it’s not over after every few hours resulting in loss in production) automated lines needing uninterrupted supplies requiring storage requirements, better availability and competitiveness necessitating larger imports, needing lesser number of people for doing same work requiring handling more quantity each time etc.
Unlike regular storage containers, pallet bins are made to be used in an industrial environment. This means that they have heavy duty walls, bases and lids if necessary. They are also made to withstand the elements when used for outdoor storage or shipping. Some are even designed to nest inside one another when empty so that you can save space.
Key Features of Pallet Bins
Integrated Pallet Base: Built in pallet base for safe and easy lifting, moving and stacking with material handling equipment. Many pallet bins have a high load capacity, often holding hundreds of kilograms or liters of product, making them ideal for heavy-duty use. Pallet bins are designed to be stacked vertically, whether they are full or empty in order to maximize warehouse space and minimize transport costs.
- Collapsibility (Optional): Some variant of plastic pallet bins come with collapsible walls that can be folded down when the bin will not be in use, thus saving on space occupied during return shipping.
- Durable Plastic Construction: Most of the pallet bins are made making use of plastic injection mold technology which makes the bins last-long, high-strength, precision &, highly wear-resistant.
- Customization Options: Bins can be customized to include your company logo, color coding, RFID tracking slots, or food-grade finish.
What is Plastic Injection Mold?
Plastic injection mold process is the most commonly used manufacturing process for making large volume of plastic parts in a quick and economic way, where molten plastic material is injected into a mold cavity at high pressure with a preset cycle time to shape the product, and this custom plastic mold tooling is made by a complex manufacturing process called injection mold.
This process is the basis of contemporary plastic production and is the method favored for manufacturing anything from tiny items to large industrial storage applications such as plastic pallet bins.
Key Components of a Plastic Injection Mold System
- Injection Unit: This is where molds are made from. Plastic pellets or granules such as HDPE or PP are fed into the injection molding machine via a hopper. The molds are then formed using the molten plastic which will cool down to form the shape of your desired pallet. Pellets can be purchased in bags by weight. End Products After Molding Technology.
- Mold Tooling (Mold Cavity): A mold tool is the generic term used to describe the tooling used in conjunction with an injection molding machine.
- Clamping Unit: The clamping unit makes sure that both halves of the mold are held tightly together during the injection, as considerable pressure is applied for opening the mold to its desired position.
- Cooling System: When molten plastic fills the mold cavity, it needs to cool and solidify quickly to form the part. Cooling lines (usually water/glycol) run throughout the mold to reduce cycle time and ensure uniform solidification.
- Ejection System: After the plastic solidifies, the mold opens, and ejector pins or plates push the finished product out. For larger items like pallet bins, the ejection system must be strong and well-designed to prevent part damage.
