This article talks about the TPR plastic material and TPR plastic material injection molding process.
TPR plastic material
According to the characteristics of the material and the supply situation, the appearance and process performance of the material should be tested before injection molding.
The injection mold acceptance standard is recognized from the product quality, mold structure, injection molding process requirements, etc., accordingly, the injection mold quality is evaluated.
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?

What is M2M technology?
The following is knowledge of M2M technology.
Common products are wireless embedded data modules that support GSM / GPRS or CDMA wireless mobile communication networks.
Commonly used techniques such as barcode technology, RF identification card RFID technology, etc.Communication networks are in a core status throughout the M2M technology framework, including WAN, LAN (Ethernet, Wireless LAN WLAN, Bluetooth), Domain Network (Zigbee, Sensor Networks).
With the evolution of mobile communication technology to 3G, it is certain to bring M2M applications to a new realm.

The 5G core network (5GC) is the brain of the 5G mobile communication network, which is responsible for managing and controlling the entire network.
The 5G core network is a collective name of many 5G NE equipment and is not specifically referred to as a network element device.
AMF (Access and Mobility Management Function Access and Mobility Management) supports a UE with different mobility management requirements. AMF can be classified as 4G MME.
Store and manage the permanent user ID (SUPI) of the 5G system;
AN (Access Network) is the access network, which can be a 3GPP access network (such as LTE, 5G-NR), or a Non-3GPP access network (such as common WiFi access).
While 5G has been a hot topic for years, there is still a great deal of work to be done behind the scenes in refining and effectively iterating on 5G standards.
5G NR (New Radio) Release 16 brings critical reliability and latency improvement technologies in several key areas, most notably an enhanced 5G URLLC base to deliver better link reliability (up to 99.9999%).
These networks have gained significant traction in industrial IoT use cases, enabling enterprises to deploy 5G industrial IoT networks with dedicated resources immediately, rather than waiting for broader 5G network deployments. Other benefits include specific optimizations for local applications and customized security and privacy settings when needed.

Apple's first use of UWB is to provide positioning data. Location Supports Many applications in the fields of reality (AR), virtual reality (VR), games, equipment recovery, file sharing, and advertising beacons.
Development of UWB technology
With the growth of wireless communication demand in 1990, the advantages of ultra-wideband (UWB) become more obvious.
In 2002, Wi-Fi is still a relatively new technology. The 802.11b router was launched in 1999, the theoretical maximum speed of the 2.4 GHz band is 11 Mbit / s.
802.11A standard is also defined in 1999 and promised that the theoretical speed in the 5 GHz band is 54 Mbit / s, but due to its higher chip group cost, there is no attention in the consumer.
The 7.5 GHz bandwidth allocated between 3.1 GHz and 10.6 GHz is extremely valuable for wireless communication engineers.
Today, we are going to talk about the 5G-Advanced innovation’s dual-chain integration, five major forces, and three driving factors.
The subsequent “5G-Advanced Evolution White Paper” analyzed the 5G-Advanced network evolution architecture and technology development trends in detail for the first time, and strived to point out the direction to promote 5G to generate greater social and economic value.
Respondents believe that LTE or Wi-Fi cannot meet their current industrial needs, and people agree that 5G is more suitable for industrial applications. 28% of the interviewees believe that performance advantages force 5G to be preferred for scenarios requiring wireless in industrial networks.
After the read, you can get the latest 5G/NB-IoT/LTE-Cat1/LoRa/Bluetooth/WiFi and other IoT wireless technology trends.
Over this period, the new 5G will contribute US$2.1 trillion in annual net GDP. This forecast is dependent on the actual commercialization of 5G new radio, which is the most noteworthy aspect of 5G.
The future of live streaming applications will be more rapid with the support of 5GNR.
Some data indicates that in cellular IoT connections, 60% of IoT connections require the narrowband network to provide services, about 10% of high-speed services require 4G Cat 4 or above or 5G eMBB to provide services, while the remaining 30% of low and medium rate IoT requires LTE Cat 1 or eMTC network to provide services.
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.
