Transparent Storage Box Molds are specialized injection molds designed for producing various types of transparent plastic storage containers. They efficiently and precisely manufacture storage boxes with high clarity, structural integrity, and are typically used with materials like PP, PS, or AS. These molds have extremely high requirements for optical performance, surface finish, and demolding characteristics, making them widely applicable in home organization, stationery sorting, food storage, retail display, and industrial parts storage.

Core Advantages of Yige Mold

Yige Mold leverages extensive expertise in the transparent product mold sector to provide customers with end-to-end solutions from design to mass production. We deeply understand the stringent demands for flawless appearance, high light transmittance, and excellent dimensional stability in transparent containers, and ensure their realization through precision manufacturing.

Key Technical Highlights

1. High-Polishing Technology: Mold cavities undergo diamond paste mirror polishing or electropolishing, achieving a surface finish of A1 grade or above. This ensures crystal-clear box bodies, free from defects like flow marks, ripples, or air streaks.

2. Optimized Venting System: Designed specifically for transparent materials, the multi-stage, uniform venting system effectively prevents issues like black speckles, burn marks, or short shots caused by trapped air, thereby improving yield rates.

3. Runner and Gate Design: Utilizes hot runner systems (valve-gate or open-gate) or cold-to-hot runner designs to ensure rapid and uniform melt filling. This minimizes the visibility of weld lines and achieves minimal gate vestige.

4. Precise Temperature Control System: Features an efficient and balanced cooling circuit design, ensuring stable and uniform mold temperature. This is critical for preventing product warpage and guaranteeing dimensional accuracy and clarity.

5. Ejection System Planning: Employs specialized designs such as blade ejectors, air-assisted ejection, or delayed ejection to avoid visible ejection marks on appearance surfaces, maintaining a perfect product finish.

Primary Application Areas

• Home & Living: Wardrobe storage boxes, toy organizers, shoe boxes, refrigerator food containers.

• Office & Stationery: File boxes, card and receipt organizers, desktop clutter boxes.

• Commercial Retail: Product display boxes, cosmetic organizers, gift packaging boxes.

• Industrial Warehousing: Small parts identification boxes, tool sorting boxes, dust-proof inspection boxes.
