The advantages and disadvantages of silicone composite film

Duplicate mold refers to the use of the original template, in vacuum state to make silicone mold, and in vacuum state using PU material for pouring, so as to clone the same as the original template.

1. Prototype: Before making silicone molds, you need to make prototypes. The prototype can be made of common ABS material and CNC machining.

2. After the silicone mold prototype is ready, the silicone mold is made. After eight hours of drying, the silicone mold is cut open and the prototype is removed. At this point the silicone mold is ready.

3. Injection type: Inject the liquid gum material into the silicone mold and dry it. The service life of the silicone mold is about 25 molds.

Advantages and disadvantages of silicone composite film:

The advantage is that the time is fast, the cost is less, the probability of processing failure is small. More than 20 of the same products can be made using a silicone mold. Greatly reduced product development cost, cycle and risk.

The disadvantages are that the mold is not resistant to acid and alkali, aging resistance, short life, easy to appear traces, stripes, not smooth phenomenon on the surface of the mold, and the product accuracy is not high.

Key points of silica gel cladding process:

1. The amount of curing agent should be determined by temperature, and the temperature is high. If the curing agent is used too much, the mold will become hard and brittle; The curing agent is used too little, the operation time will be prolonged.

2, in order to prevent the mold silica gel physical property changes, it is recommended not to add silicone oil.

3. In order to achieve the best use effect of your mold, please store the mold for at least 24 hours before use.

4, hard mold can also be made of resin.

Application range of silicone composite film:

Mainly used in toy and gift industry, craft gift industry, furniture decoration industry, character duplication, building decoration industry, animal and plant sculpture simulation, Buddha sculpture crafts and other industries of product duplication and mold production.
