In the process of injection molding, carelessness can cause injection molded product defects, how to prevent injection molded product defects?
If the diameter of the nozzle is too small, the specific volume of the material increases, and it is easy to cause cold, blocking the feed channel or consuming the injection pressure; in the cooling effect of the template hardened, thus preventing the smooth entry of molten material into the cavity.
For multi-cavity molds, the runner should be carefully arranged and the size of the sprue should be balanced, otherwise, only the cavities near the main flow path or the thick and short sprue can be filled, while the other cavities cannot be filled.
After read, you can learn about how to adjust the injection molding processes of temperature, pressure, and speed.
Injection molding temperature measurement and control are very important in injection moulding. Although these measurements are relatively simple, most injection molding machines do not have sufficient temperature tights or lines.
In order to counter the injection molding pressure, the locking mold pressure must be used, do not automatically select the maximum value available, and consider the projected area, calculate a suitable value.
This is the pressure that must be generated and transcended before the screw.

The cooling water juice should be used in the plastic block insertion mouth, and the customer needs to request.
The hardness of the mold components should not be less than 50 HRC, or the surface hardening treatment hardness should be higher than 600 hV.
The reset spring should be used as a standard piece, and the spring should not be ground and cut.
Below are the 18 basic injection molding technologies that injection molding technicians must know.
The melt usually flows from the nozzle into the nozzle, but in some injection molds, the nozzle is part of the mold because it extends to the bottom of the mold. There are also two main types of nozzles: open nozzles and closed nozzles. In injection molding, open nozzles should be used more because they are cheaper and less likely to stay.
Make sure that the nozzle is correctly connected to the nozzle bushing, and the top hole is slightly smaller than the nozzle sprue bushing.
When it comes to molding defects, burn marks in injection molding are some of the most common. Why have burn marks in injection molding?
Today, we talk about the 5G NR MIMO Transmission ways. What are the required transmission schemes for NR MIMO?
There are three implementation options for the 5G NR beam assignment, which are analog, digital, and hybrid beam assignment. For these implementations, both multibeam-based and single-beam-based approaches should be considered. But what are the required transmission schemes for the 5G NR MIMO?
In LTE, single layer/multi-layer/TP/UE transmissions use a unified framework. Due to the flexibility of DMRS, these transmissions have good transparency. In 5G NR, multi-beam transmissions can also be seen as cooperative transmissions between multiple virtual TPs.
Considering the cost and complexity, when there are more antenna units and the number of RXUs is usually smaller than the number of originals.

LoRa network is one of the low-power WAN communication technologies and is a proprietary Semtech technology for ultra-long-range wireless transmission based on spread spectrum technology.
One of the key considerations when planning a dedicated wireless network may be the use of licensed or unlicensed channels. While some of the new LTE NB-IoT products can operate on unlicensed bands, most cellular devices operate on licensed spectrum.
WiFi and Bluetooth use unlicensed spectrum in the 2.4 GHz and 5 GHz bands. Despite this, those frequencies are still so crowded that they pose serious reliability problems and the range of gateways is limited to a few meters.
What is LoRaWAN and what is LoRaWAN advantage?
LoRa is generally used in IoT devices that require only simple control data and status data transmission such as simple switch-closing type actions, keeping IoT devices energy efficient, and low power consumption so that the status of the device can be easily known in unmanaged places.
What is the difference between LoRa and LoraWAN?
LoRa and LoRaWAN are the two hottest wireless communication technologies in IoT, and it is hard for many people who are new to IoT to distinguish the difference between LoRa and LoraWAN.
