Plastic storage basket production process
The storage basket mold consists of two plates: the core and the cavity. The mold has a cycle time of 10.8 seconds, including injection and cooling time. The number of cavities in a storage basket mold can range from one to four. To manufacture the mold, we use P-20-2738 pre-hardened HRC40-42 material, which we carefully polish, chrome-plated, nitrided, and vacuum-hardened.

Plastic storage basket mold technical documentation
The core of efficient, large-scale, and continuous production of storage baskets lies in a precision industrial piece of equipment: the plastic storage basket mold. From plastic pellets to the final basket shape, everything depends entirely on a highly complex, meticulously designed and engineered injection molding system.
Plastic storage basket design
The design of plastic storage basket molds presents several challenges, primarily stemming from the product’s functional and geometric requirements. Key design considerations include:
Uniform wall thickness and cooling control
Storage baskets require sufficient strength and load-bearing capacity, so uniform wall thickness distribution is crucial. Uneven wall thickness can lead to uneven cooling, potentially causing warping, deformation, or stress cracking. Cooling system design is crucial to ensure effective heat dissipation to avoid localized overheating or undercooling that can slow production and negatively impact basket quality.
Deep cavity walls and flow resistance
Storage baskets typically have deep walls, which require molten plastic to flow a long distance to fully fill the cavity. Flow resistance increases with distance, and poor flow channel design can lead to incomplete filling (short shots), flow marks, or weld lines. This not only affects molding quality but can also result in strength and cosmetic defects in the final product.
Bottom support structure and cooling efficiency
To support the weight and prevent sagging, the bottom of a storage basket often features a mesh or rib structure. These areas can become “hot spots” where heat accumulates, resulting in slower cooling. Mold cooling channel design requires special attention to ensure uniform and effective cooling in these areas to prevent hot spots and uneven cooling that can lead to deformation or stress accumulation.
Surface texture and mold release requirements
Storage baskets often feature a non-slip texture on their bottoms to increase friction and durability. However, the texture depth and draft angle must be carefully designed to prevent sticking. Complex textures require a smooth mold surface finish, which is crucial for both product appearance and mold release.
Stacking/nesting design compatibility
Storage baskets often require stacking or nesting capabilities to optimize storage and shipping space. Therefore, mold design must ensure product shape accuracy during mass production and ensure stable stacking or nesting of baskets molded from multiple molds.
Plastic storage basket mold system
To overcome the challenges and ensure efficient production, plastic storage basket molds utilize several precisely engineered systems:
Slide motion system (Side action)
Side handles, reinforcements, or bottom edges of storage baskets often create undercuts, making them impractical to eject via standard core/cavity separation. The solution is the use of slide components, typically driven by hydraulic cylinders or tilting guide pins. These slides follow a precisely calculated path before and during mold opening to prevent undercuts on the plastic part. The slide’s motion accuracy and durability (achieved through high hardness and effective lubrication) directly impact mold life and product quality.
Ejection system
Once the mold cools and solidifies, the molded basket must be cleanly ejected from the cavity. To prevent deformation, the mold utilizes a combination of ejector pins and ejector vanes. The ejector vanes provide uniform support over a large area, while the ejector pins are used for localized, critical features. The entire ejection system is driven by the injection molding machine’s ejector mechanism and ensures accuracy through precise motion path and force control.
Efficient cooling system
To shorten production cycle times and eliminate hot spots, molds utilize a dense network of cooling channels. Cooling channels should be designed as close to the cavity and core surfaces as possible, especially in hot spots such as deep cavities, grid nodes, and rib intersections. Channel diameter, connection method, and coolant flow control have a direct impact on cooling efficiency. Deep-cavity molds often require specially designed baffle cooling channels to ensure uniform cooling and effectively reduce production cycle times.
Runners and gating systems
The mold’s runners and gating system are critical to the smooth flow of molten plastic. Precise runner design ensures uniform flow of molten plastic into the cavity, avoiding areas of overfill or underfill. Using a hot runner system can reduce cooling time and minimize material waste. For large storage baskets, molds often utilize multiple hot runner gates to ensure even filling and improve production efficiency.
Hot runners
The temperature control accuracy of a hot runner system directly impacts product quality. Uneven temperatures can lead to poor molten plastic flow, impairing filling efficiency and even causing weld lines or surface defects. Therefore, choosing a hot runner system with multi-zone independent temperature control can maintain uniform temperature distribution during production and avoid quality issues caused by temperature fluctuations.
In multi-cavity molds, plastic flow must be balanced, and all gates should open simultaneously to ensure uniform plastic filling of each cavity. Unbalanced runner design can result in underfilling in some areas and overfilling in others, compromising final product quality. Runner dimensions require careful design. Too small will result in pressure loss, while too large will prolong the plastic’s residence time in the system, compromising material properties.
Material selection
The durability of a plastic storage basket mold directly determines its lifespan, maintenance costs, and production stability:
The cavity and core molds must be made of mold steels with high hardness and good thermal conductivity, such as P20 and H13, to ensure stable performance under high temperature and high pressure conditions. These steels are not only wear-resistant but also have excellent polishability and toughness, ensuring mold precision over long-term use.
Guide pins and bushings are typically made of hardened high-carbon alloy steel; ejector pins and return rods are typically made of tool steel or specialized ejector pin materials; and the mold plates are constructed of high-strength structural steel to ensure overall mold stability and durability.
Common mold steels include P20 (core and cavity) and C45 (mold base), typically with a hardness of 35-38 HRC. With proper heat treatment, these steels can effectively extend mold life and reduce maintenance requirements during production.
Plastic storage basket mold manufacturing
High-quality plastic storage basket molds rely on precision machining and strict quality control:
Core manufacturing technologies
- CNC machining centers: Used for rough and finish machining of molds, ensuring high positioning accuracy and repeatability.
- Electrical discharge machining (EDM): Suitable for deep cavities, complex contours, and high-precision cutting, ensuring precision in details and difficult-to-machine areas.
- Precision grinding: Used to ensure part flatness, dimensional tolerances, and precise fit, especially on the guide pin/bushing interface and sliding surfaces of the mold.
Surface treatment
- Polishing: Gradually removes machining marks to achieve a mirror finish, ensuring a smooth part for easy demolding.
- Surface enhancement: Technologies such as nitriding or PVD coating improve component hardness, wear resistance, and corrosion resistance, extending the life of the mold.
Commissioning and production
After mold manufacturing is complete, it undergoes rigorous commissioning and trial production to ensure production capacity and product quality:
Dry cycle
Mold opening and closing, slide movement, and ejector function are inspected to ensure there is no sticking or abnormal noise.
Sampling (Test shot)
Production material is used for trial production to check the filling integrity, dimensions, appearance, and quality of the product. Based on the sample results, the injection process (such as temperature, pressure, and speed) is adjusted to optimize production efficiency and quality.
Mass production
After passing verification, the mold enters the mass production stage, where it begins to withstand frequent mechanical cycles, temperature fluctuations, and material wear over a long period of time. Stability and high yield rates during the production process guarantee the quality of the final product.
