Introduction to Injection Molds: 1. Definition of Injection Molds, Plastic Injection Molding

Low-pressure injection molding is an encapsulation process where hot melt adhesive is injected into a mold at very low injection pressure (as low as 1.5 bar) and rapidly cured (5-50 seconds). Leveraging the sealing properties and excellent physical and chemical performance of hot melt adhesives, it achieves insulation, temperature resistance, impact resistance, shock absorption, moisture resistance, waterproofing, dustproofing, and chemical corrosion resistance. It also provides excellent protection for fragile and sensitive electronic components, even properly encapsulating FPCs. Compared to traditional processes such as potting and coating, low-pressure injection molding is not only environmentally friendly but also enhances production efficiency and helps reduce overall production costs.
