China OEM 10 Types Plastic Resin And Application Factory - Double-injection waterproof plastic case of intercom walkie-talkie – Mestech

In design of electronic products, engineers usually use the hard shell to provide space for the internal components and resist external forces, and use the compression deformation of the elastomer to achieve the sealing from water.

It is an important application of double injection molding that elastomer plastic resin cover hard plastic base to create the waterproof housing for electronic products. For example, the double injection water proof case for Walkie Talkie.

Walkie-talkies also is called intercom or interphone.Mestech provides injection moulding for plastic case of intercom (walkie-talkie), including general walkie-talkies and waterproof walkies.

Intercom (walkie-talkie) is a kind of traditional communication equipment earlier than mobile phone application. Compared with mobile phone, its work does not need network and base station, is not limited by environmentalinterference, and the standby captain saves electricity and does not need to spend telecom fee.

The advantages of communication fees are still widely used in large construction sites, office buildings, shopping malls and field operations. So Intercom still has a big market.Compared with mobile phone, its work does not need network and base station, is not limited by environmental interference, and the standby captain saves electricity and does not need to spend telecom fee.

*Plastic case for general walkie-talkie

The general walkie-talkies is usually used in indoor environment, such as office building, supermarket, theater, factory,  etc. It is no need suffer water, rain, moisture, dust and falling and collision. So it’s design and material does not consider the waterproof and sealability.

Plastic case for general walkie-talkies normally use materal PC/ABS,ABS and PC, and injection molding through single-shot. It generally consist of below plastic parts:

1.Upper case:  Material PC/ABS, single-shot

2.Lower case:  Material PC/ABS, single-shot

3.On/off key:  Material PC/ABS, single-shot

4.Setting key and number keypad:

The electronic equipment used in the field involves waterproof problems, such as waterproof walkie talkie, waterproof mobile phone, waterproof watch, field detector, etc. Many electronic products and instruments will use double injection waterproof shell because of the waterproof requirements.
