In October last year, Apple launched the third-generation TWS (True Wireless Stereo) headset, AirPods Pro, on the official website for $ 249. This price is higher than the previous two generations, but it has not hit consumer enthusiasm in the slightest. Earlier, the two generations of TWS headphones released by Apple reversed the decline in sales after the release of ordinary electronic products, and became absolute benchmarks for the TWS headphones industry.
The TWS headset is not just a sound transmission tool. Its more important role is an AI assistant based on voice interaction technology. As a smart wearable device, the TWS headset is designed to provide a better human-machine interaction experience. For consumers of TWS headsets, the instant automatic connection can be achieved after the initial setting, so a smooth user experience is more important than sound quality. This can also provide some explanation for "why AirPods can produce word-of-mouth effect and become Apple&…

3.IML technology
The outstanding features of in-mold insertinjection molding (IML) technology are: the surface is a hardened transparent film, the middle is a printed pattern layer, and the back is a plastic layer. Because the ink is sandwiched between, the product can prevent the surface from being scratched and resistant. It can rub and keep the color vivid for a long time.
IML technology production process:

IMLtechnology product effect:
1）Diversification of printing appearance effects: By combining soft-touch transfer printing with printing technologies such as color and electroplating, various appearances can be realized.
2） The research and development of ultra-thin IML, the thinnest can reach 0.80mm, and the deformation is less than 0.5mm; the deformation of 6-inch battery cover is less than 1.0mm; the thickness of local glue reduction can be 0.6mm.
development trend:
In the existing equipment and process flow of IML technology, the improvement has evolved into an IMT process that is m…

The 5G era is approaching. Mobile phone shell material from plastic to metal and non-metal material cycle, plastic because of the low cost, favored by the low-end market The evolution from the IML to the IMT process has made plastics more useful, which can approach the 3D optical texture of the simulated glass back cover, and has become the choice of many CMF designers. LDS has been widely used in plastic rear case antennas in the 4G era, but whether it can be adapted to the high-end curved glass 3D back cover of the 5G era needs to continue to be developed. IMT technology can be further extended to IME technology, which integrates electrical and decorative functions and is applied to the intelligent surface of future cars. Injection molded transparent PC back cover, as a lower cost and more efficient product form, with better impact strength and durability, is attracting more and more attention from traditional plastic factories. 1.LDS technology The principle of LDS technology is to exc…

The structure of the hot runner mold is generally the same as that of the thin nozzle. The biggest difference is that the runner is located in one or more hot runner plates and hot nozzles with constant temperature. There is no cold material demoulding, the runner and gate are directly on the product.
Therefore, the runner does not need to be demolded. This system is also known as the nozzleless system, which can save raw materials. It is suitable for the product that the raw materials are expensive and the product requirements are high.
Hot runner system, also known as hot sprue system, is mainly composed of hot runner sleeve, hot runner plate and temperature control electric box. There are two types of hot runner system: single point hot sprue and multi-point hot sprue.
Single-point hot sprue is to use a single hot sprue sleeve to inject molten plastic into the cavity directly. It is suitable for plastic molds with single-cavity and single-gate; multi-point hot-gate is to branch the mo…

First, injection mold
1. If the mold cavity is not processed well, if there are scars, micro holes, wear, roughness, etc., it will inevitably reflect on the plastic part, making the plastic part poor in gloss. In this regard, the mold must be carefully processed to make the surface of the cavity Small roughness, polishing chrome plating if necessary.  2. If the surface of the cavity has oil stains, water stains, or too much release agent, the surface of the plastic part will be dark and dull. In this regard, you should remove the oil stains and water stains in time, and limit the use of mold release agents. 3. If the demolding angle of the plastic part is too small, it is difficult to demold, or the force is too large during demolding, so that the surface gloss of the plastic part is the best. In this regard, the demolding angle of the plastic part should be increased. 4. If the mold exhaust is poor, too much gas stays in the mold, which also causes poor gloss. For this, check and correct…

What are TWS Bluetooth headsets? Why is TWS headsets a lifestyle in addition to wearable? From a macro perspective, wireless and multi-device collaboration is the mega trend. On the micro level, the arrival of Bluetooth 5.0 has enabled TWS headsets to be upgraded with the underlying technology; global smartphones have gradually eliminated the headphone jack, which has accelerated the development of TWS headsets. The emergence of TWS headphones can be said to be a necessity. TWS headsets are not accepted by consumers and the market from the beginning. There are many problems such as battery life, transmission, sound quality, and price, which have not been completely resolved so far. As more and more consumers begin to pay attention to TWS headsets, demands such as voice assistants, health monitoring, and noise reduction modes also begin to emerge. TWS will become the mainstream of mobile phones in the future.Why?
