The European market is showing growing demand for plastic rattan-style baskets, laundry baskets with intricate rattan designs, and other innovative styles. 

Additionally, colorful laundry basket molds require exceptional precision to meet market expectations. Guangchao Mould provides top-quality, high-speed injection molds with options for multi-cavity configurations, catering to diverse basket designs and production needs.

Plastic baskets can also be easily modified for a variety of purposes such as home storage, seating, coffee tables, bedside tables and growing vegetables. For example, plastic baskets can be converted into storage baskets, shelves or fixed to the wall for sorting storage; The sturdy plastic basket can also be transformed into a stool, coffee table or table; Plastic baskets can also be used to grow vegetables, covered with plastic film fill soil can grow strawberries and other crops.

1. What does a plastic basket mold consist of ?

Basket molds are plastic injection molds used to produce plastic baskets. They are made up of a series of cores, cavities, sliders, and stripper plates.

Cores : Cores are the parts of the mold that define the internal features or cavities of the molded plastic part.

In a plastic basket mold, cores create the hollow parts of the basket, such as the spaces between the ribs or the handles. The core inserts into the mold to form the inner shape of the part during the injection molding process.

In a plastic basket mold, the core might be used to form the internal cavities where air or liquids can flow, ensuring the basket is lightweight and functional.

Cavities : Cavities refer to the spaces in the mold that form the external shape of the plastic part. The cavity side of the mold is where the molten plastic is injected, and it takes the shape of the final product's outer surface.

The cavity is the counterpart to the core. While the core forms the internal features, the cavity defines the outer geometry of the part. In a plastic basket mold, the cavity will form the outer walls, base, and ribs of the basket.

Slider : Sliders are movable components that allow the mold to form features that cannot be created by the traditional mold opening and closing motion alone.

Sliders are used to form undercuts or complex geometry in the plastic part. They can slide laterally or vertically to create features such as latches, grooves, or other details on the basket that cannot be molded directly from the top-down mold opening. After the part has cooled and hardened, the slider moves to release the molded piece.

Stripper Plates: Stripper plates are components that help remove the molded plastic part from the mold after it has cooled and solidified. These plates are typically used in conjunction with ejector pins or other mechanisms to push the part out of the cavity.

In a word ,cores create internal features ,cavities form the external shape of the part ,sliders are used for creating complex or undercut features and stripper plates help remove the part from the mold after cooling .These four components all work together to ensure that the plastic basket mold functions efficiently and produces accurate, high-quality parts.

2. What are the key design considerations for plastic basket molds?

Start by considering the product design requirements.

Ensure uniform wall thickness to prevent warping, sink marks, and uneven cooling; typically, 2-3 mm is sufficient.

The product design should align with its intended use, such as laundry baskets or storage baskets, while incorporating features like stackability and nesting to save space during transportation and storage.

Reinforce critical areas, such as handles or corners, with ribs or supports to enhance durability. Avoid sharp corners to reduce stress concentrations and improve mold flow.

Additionally, textures, logos, or patterns, such as rattan or decorative designs, can be added to enhance the product’s visual appeal.

Mold Structure

Design the core for internal features and the cavity for the external shape, ensuring precise alignment to prevent defects.

Include draft angles (1°–3°) on vertical walls for easy ejection without damage.

Use sliders or lifters to handle undercuts, such as handle holes or complex designs.

Position the parting line to minimize visible marks and ensure smooth mold operation.

Gate and Runner Design  

Place the gate in a position that ensures even filling and minimizes visible marks, preferably in central or inconspicuous areas.

Opt for a hot runner system to reduce waste and improve efficiency, or a well-designed cold runner for cost savings.

Ensure balanced flow to prevent short shots or weld lines in complex designs.

Cooling System

 

Design cooling channels near thicker sections to ensure uniform cooling and prevent warping. Use copper or beryllium copper inserts for improved thermal conductivity.

Optimize the cooling layout to reduce cycle time while maintaining part quality.

Ejection System

Use ejector pins, stripper plates, or air ejection to remove parts without damaging delicate features. Ensure uniform ejection force to prevent deformation, especially for large or thin-walled baskets.

Material Selection

Mold material : Use durable materials like P20 steel, H13 steel, or stainless steel to withstand wear, especially for high-volume production.

Products material : Choose resin based on the basket's purpose (e.g., PP for lightweight and flexible designs, HDPE for added durability).

3. What are the common challenges in manufacturing plastic basket molds?

1. Complex Designs: Adding features like patterns or holes can make the mold harder to create.

2. Wall Thickness: Keeping the walls even to avoid warping or defects.

3. Cooling: Designing a system to cool evenly and quickly without causing issues.

4. Material Flow: Ensuring the plastic fills the mold properly without defects.

5. Ejection: Getting the part out of the mold without damage, especially for large or thin baskets.

6. Mold Wear: Molds can wear out with time, affecting production.

7. Cost: Balancing high quality with cost-efficiency.
