Injection molding machinery is the core large-scale molding equipment in the daily necessities packaging industry, covering the production of all categories of plastic packaging, from small portable parts and medium-sized containers to large storage items. Mass production of everything from food and daily chemical packaging to household storage packaging relies on injection molding machines. The core requirements for plastic parts in daily necessities packaging are low cost, high output, neat appearance, and adaptable structure (sealing, portability, stacking, etc.). The core value of injection molding machines in this field lies in achieving large-scale, standardized, and cost-effective production of packaging parts through high-speed mass production with multiple cavities in a single mold, efficient plasticization of universal materials, rapid molding of simple structures, and low-cost process adaptability. This simultaneously considers the functionality (sealing, moisture-proofing, leak-proofing) and appearance (printing, color matching, and design) of the packaging, making it a key support for achieving widespread adoption, diverse product categories, and controllable costs in daily necessities packaging.

Compared to other molding processes (blow molding, thermoforming), injection molding machines are more suited to rigid structures, precise fits, and multi-cavity mass production in daily necessities packaging. They fill the gaps in product categories left by blow molding (suitable for soft/hollow large containers) and thermoforming (suitable for thin-walled shallow boxes), covering over 60% of daily necessities packaging production needs. The following details their core functions, typical application scenarios, dedicated technology adaptation, and machine selection principles, aligning with the industry's practical needs for mass production, low cost, and high adaptability:

I. Six Core Functions of Injection Molding Machinery in Daily Necessities Packaging

1. High-speed mass production with multiple cavities in a single mold, achieving extremely low packaging costs.

2. Efficient plasticization of general-purpose plastics, adapting to mainstream packaging raw materials and reducing costs.

3. Precise molding of functional structures, ensuring the usability of packaging.

4. Integrated molding of multiple processes, simplifying post-packaging processes and improving efficiency.

5. Flexible production adaptation, meeting the needs of multiple packaging categories and specifications.

6. Large size/ Thin-wall molding covers the entire range of packaging production. Injection molding machinery plays a crucial role in the daily necessities packaging industry, serving as the core carrier for realizing the transformation of packaging from design to large-scale mass production. Its core capabilities—high-speed mass production, universal material adaptability, functional structure molding, and low-cost processes—determine the unit price, production capacity, quality, and functionality of daily necessities packaging. It is key to achieving "high cost-effectiveness, massive supply, and diverse product categories" in daily necessities packaging.

From bottle caps costing a few cents to storage boxes costing tens of yuan, injection molding machines cover the entire range of daily necessities packaging production. Simultaneously, with the development of green packaging, lightweight packaging, and intelligent packaging, injection molding machines are continuously upgrading towards energy conservation, greening, intelligence, and integration, becoming a core component of intelligent manufacturing and green development in the daily necessities packaging industry.
