3. Technical Advantages and Industrial Applications

Injection molding has become an indispensable manufacturing technology in multiple fields due to its unique advantages:

1. High-Efficiency Mass Production：A single mold can be reused tens of thousands to millions of times. A 32-cavity bottle cap mold can produce up to 15,000 pieces per hour, supporting high-frequency demands such as beverages and medical consumables.
2. Design Flexibility：It can integrally form complex structures with undercuts, deep cavities, and thin walls (minimum 0.1mm). For example, a laptop touchpad with more than ten features such as positioning posts and heat dissipation holes can be formed in one step, reducing 80% of assembly processes.
3. Precision and Consistency：Dimensional tolerance can be controlled within ±0.05mm, and surface roughness Ra ≤ 1.6μm, meeting the requirements of precision parts such as electronic connectors and medical adapters.

Its applications have penetrated into various life and industrial scenarios:

• Automotive Industry：A car contains 2,000-3,000 injection-molded parts. For example, engine components made of PA66 + glass fiber achieve vehicle lightweight and energy consumption reduction;
• Medical Field：Using FDA-certified medical-grade plastics, sterile consumables such as syringes and infusion sets are produced in clean workshops, with mold mirror polishing to avoid bacterial residue;
• Electronics Industry：Processing 5G base station connectors (tolerance ±0.01mm) and mobile phone charger housings to ensure precise equipment adaptation.
