How much do you know about the mold making process of liquid silicone phone case?

As an important part of the mobile phone, the mobile phone shell plays a role in beautifying the appearance of the mobile phone while protecting the mobile phone. Liquid silicone mobile phone case is widely used because of its soft, durable and environmental protection characteristics. The following will introduce the mold production process of liquid silicone mobile phone case.

Raw material preparation

First prepare the following raw materials:

Liquid silicone: Select the appropriate liquid silicone according to the color and material requirements of the phone case.

Silica gel curing agent: According to the ratio of liquid silica gel, select the matching silicone curing agent.

Liquid silicone syringe: Used to inject liquid silicone into the mold.

Mold opening: According to the mobile phone model design and production of mold opening.

Mold production steps

The following is the opening process of liquid silicone phone case:

1. Design the opening mold

First of all, according to the size and appearance characteristics of the mobile phone, design the mold. The design of the mold should take into account the position of the various functional holes of the mobile phone, the curve and appearance of the shell, and other factors to ensure that the mobile phone shell can perfectly fit the mobile phone, and the appearance is beautiful.

2. Mold processing

The designed mold is processed. This step is the process of making a mold that can be precisely machined using a CNC machining center or other machining equipment to ensure the accuracy and quality of the mold.

3. Apply release agent

Apply a layer of release agent to the surface of the mold so that it can be easily removed after the phone case is made.

4. Inject liquid silicone

The liquid silicone and silicone curing agent are evenly mixed in the appropriate proportion, and the liquid silicone syringe is used to inject the mixed liquid silicone into the mold opening. When injecting liquid silicone, pay attention to controlling the injection pressure and speed, so that the liquid silicone fills the entire mold space.

5. Solidify silicone

After the liquid silicone is fully filled in the mold space, the mold is placed under the appropriate temperature and humidity conditions, waiting for the silicone to cure. The specific curing time and temperature should be determined according to the requirements of liquid silicone.

6. Take out the phone cover

When the silicone curing is completed, the mold is disassembled and the cured mobile phone case is carefully removed. If cured completely, the phone case can be easily removed from the mold, otherwise it may need to be assisted by tools.

7. Post-processing

Carry out the necessary post-treatment process on the removed mobile phone case, such as removing excess silicone, cleaning, grinding, etc.

Sum up

The open mold production process of liquid silicone mobile phone case is relatively simple, but the production accuracy and quality are crucial to the quality of the final mobile phone case. Only the precise design and production of the mold, as well as the reasonable operation of the liquid silicone injection process, in order to produce the perfect fit for the mobile phone liquid silicone phone case. Therefore, each link should be strictly controlled in the production process to ensure that the final phone case has excellent quality and outstanding appearance.
