Low-pressure injection molding process is how to apply the LED on it?

Low pressure injection molding machine (injection) molding process is a method of using a very small injection pressure (1.5 ~ 40bar) encapsulating material is injected into a mold and rapidly curing (5 to 50 seconds) of the process for the package to meet insulation, heat resistance, resistance shock, vibration, moisture-proof, waterproof, dustproof, chemical resistant and so on efficacy, mainly used in sophisticated packaging and protect sensitive electronic components. Its broad range of applications, including: mobile phone batteries, printed circuit board (PCB), automotive electronics, automotive wiring harness mold, automotive connectors, sensors, micro-switches, antenna and so on.
1, to enhance the performance of the end product: the injection pressure is extremely low, non-destructive components, the defect rate is very low, the conventional high-pressure injection molding process, the injection pressure, and therefore vulnerable during the injection molding of precision components are easily damaged, resulting in the production process the defect rate high. For the shortcomings of traditional high-pressure injection molding process, Henkel Technologies provides customers with excellent performance Macromelt mobility products, this special plastic material after melting requires only minimal pressure on it to make it flow into small molds space, and therefore need not damage the fragile package components, greatly reduces the rejection rate.
The injection temperature, the low-pressure injection molding process is also lower than the temperature of the conventional high-pressure injection temperature, thus reducing the chances of damage due to high temperature sensitive, precision components. These characteristics are determined Macromelt products can compensate for the lack of traditional high-pressure injection, an ideal sensitive, precision components packaging materials, and more and more used in the automotive and electronics industries.
Excellent physical properties: good sealing: Henkel Macromelt Series Hot Melt on a variety of plastics (such as PVC, PA66, PC, ABS, etc.) and the metal has good adhesive properties, coupled with the hot melt adhesive itself low water rate, good resistance to chemical corrosion properties, injection molding after you can effectively play the encapsulated components sealed, moisture-proof, waterproof, dustproof, chemical resistant role.

High and low temperature: temperature resistance is another feature of Henkel Macromelt series of hot melt adhesive. Its operating ambient temperature range is -40 ℃ to 150 ℃, can be applied to a variety of harsh production environment and the environment.
Impact resistance: hot melt adhesive is fully cured after Macromelt series can achieve a Shore hardness of Shore A 60 ~ 90 or Shore D 40, has good toughness, can be a good cushion the impact force from the outside world, protects internal components effect. Electrical insulation: Macromelt family hot melt adhesive having excellent electrical properties, the insulating material can be done, the volume resistivity of between 1011 ~ 1014. Flame retardancy: Macromelt family hot melt adhesive also has excellent flame retardant properties, in line UL94V0 standards.
Low pressure injection (injection) molding system is generally relatively simple, only by the hot melt machine, working console and die three parts. Since the injection pressure is very low, the mold can be cast aluminum mold, small size, without the need for traditional steel, it is easy to mold design, development and manufacturing, can greatly reduce the cost of materials and the development cycle.
Since the plastic material flow is good, you do not need big tonnage clamping force, and even manual clamping, so the structural design of the mold can be very flexible. This reduces the equipment cost, but also shorten the delivery time, but given the producers more flexibility to meet customer demand. Aluminum mold cost and less development time so that the low-pressure injection molding process is the ideal way to flexible, production of many products of the project. If the alternative to traditional casting process using low pressure injection (injection) molding process, you can also save potting housing and other expenses after heat curing.
Finally, due to the low temperature and pressure, can greatly reduce the scrap rate of defective finished products, avoiding unnecessary waste. Therefore, choosing low-pressure injection (injection) molding process not only can greatly improve production efficiency and reduce the defect rate of finished products can also help enterprises to establish overall production cost advantages.
