From plastic trinkets and toys to auto parts, bottles, containers to cell phone cases, the plastic injection molding process is widely used to make parts and assemblies.​plastic molder   ， Why do manufacturers prefer this injection molding technique to make plastic products?

1. Suitable for the production of complex precision products

One of the main advantages of plastic injection molding technology is that complex plastic precision parts and assemblies can be easily designed.

2. Free choice from a variety of materials

There are a large number of plastic materials that can be used in the plastic injection molding process. There are materials such as antistatic plastics, thermoplastic rubbers, chemically resistant plastics and biocompostable materials

3. Automated processes to reduce manufacturing costs

Injection molding is an automated process. As automation reduces manufacturing costs, overhead costs are also reduced.

4. Efficient production methods

One mold can produce more products. High productivity makes plastic injection molding also efficient and cost-effective.

Mobile phone dedicated microphone advantages: built-in sound card

This kind of dedicated microphone will come with a professional sound card.​smart phone microphone  ，Its performance is more powerful than the sound card module of the mobile phone itself, which can make the sound fuller and more magnetic, instead of the thin effect, and it will not generate annoying current. Voice.

Advantages of special microphones for mobile phones: condenser pickup

A good microphone is a general condenser microphone. It can sensitively sense low-frequency sounds, perfectly record all the details of the sound, and can sense even a whisper or a long distance.

Mobile phone special microphone advantages: active noise reduction

The dedicated mobile phone microphone has been strengthened in terms of noise reduction. It can distinguish the noise through the internal circuit, and then try to reduce the noise without delay, so that the output sound is purer and more pleasant.

Choosing a good baby walker can often help children learn to walk quickly and well.​wbaby walker ，How to choose a baby walker?

It is best to choose a walker with the function of adjusting the height and height. The walker with the lifting function can adapt to the growth of the baby, and choose to continuously adjust the height at different times.

Buy products from more formal manufacturers to see if there are certificates of conformity, manuals and trademarks. Regular manufacturers produce relatively more quality assurance.

When purchasing, pay attention to whether the product technology is qualified, whether there are sharp places that may cut the child, whether the baby walker is relatively solidly assembled or whether the child’s accessible surface is rough and inferior.

For some cars with the function of educational toys, it is necessary to determine whether the quality of the toy is firm, and it is not easy to be pulled out by the baby, and it is easy to be swallowed by the baby if it is too small.

The definitions are different:

RFID card: used for contactless data communication between the reader and the tag to achieve the purpose of identifying the target.

ID card: It is a non-writable proximity card with a fixed number. It only uses “card number”. Other than the card number, there are no secret functions inside the card.

Different applications:

RFID card:​RFID cards ，animal chip, car chip anti-theft device, access control, parking lot control, production line automation, material management.

ID card: attendance, access control, card and other systems.

Features are different:

RFID card: relying on electromagnetic waves, no physical contact between the two parties is required; the reading and writing speed is extremely fast, which improves the efficiency of information transmission; each RFID tag is unique; the structure is simple, the recognition rate is high, and the required reading equipment is simple

ID card: The data storage time is more than 10 years, and the card number cannot be changed after being written before the card is sealed, which absolutely guarantees the uniqueness and security of the card number.

1. Budget

The most important thing is to choose the model that suits you according to the thickness of your wallet,​usb condenser microphone    ,   consume rationally, and prevent handcuffs.

2. Brand

Professional brands can be guaranteed whether they are products or pre-sales and after-sales services, and the chance of stepping on thunder is less.

3. Other parameters

Including transient range, dynamic range, signal-to-noise ratio, resistance, frequency response curve, response range, etc., and these parameters are only valuable for very professional microphones, especially in today’s relatively open price, the price is basically Determines the level of the microphone, so there is no need to focus too much on the parameters.
