Little knowledge about silicone - post-molding processing technology of molded silicone products
Release time:2024-02-27 14:37 Reading times:207

The original molded silicone products have a single color, are not smooth, and lack aesthetics, which greatly limits the applicable scenarios of silicone, an excellent material. Through the processing of different processes, the feel, color, visual effects, shape, etc. of silicone will become more attractive, thus having a wider scope of application.


Craftsmanship
Spraying color ink is to spray various colors visible to the naked eye on the surface of silicone buttons. The process of spraying color oil and ink is basically a process that every silicone button needs to go through. After the color spraying process, it can be sprayed or matted. process.
Spray matt ink. Matt ink is a matte feel ink. Its characteristics are actually similar to PU ink. However, spraying matt ink will make the surface of the silicone button appear matte, and it can spray a frosted effect. The feel is also comparable. It’s smoother than ever!
Spray touch oil, and the product pressed out of the pressed silicone is slightly sticky. After spraying with oil with specific effects, it will overcome the shortcomings of the silicone product and make it show more characteristics; common colored oils, matting oils , anti-scratch oil, water-based touch oil, etc.; such as spraying oil on the silicone phone case to make it feel softer and smoother to hold.

Spray PU
PU related knowledge:
Differences and applications of product spray PU paint and UV paint
What is the difference between ink and paint coating?
Spraying PU is to spray PU on the surface of silicone to achieve protection or coloring.

Glue
Introduction to Epoxy
Apply glue to the silicone to improve the surface feel of the silicone. You can also add various decorations to the glue to beautify the product.
Example: Glue phone case is to add a layer of glue on the surface of the silicone phone case to achieve the effect of stars and moon.
pad printing
How to make pad printing rubber head from pad printing silicone
Belongs to letterpress printing. It is to use the plastic head as a carrier to transfer the pattern on the steel plate to the toy product. Pad printing silicone requires fine quality, no impurities, good resilience, good oiling, and clear pattern printing. This process is a bit like stamping. The pad printing head is the official seal, and oiling is to dip the official seal in red oil.

silk screen
Silk screen printing silicone four major printing methods and characteristics
It belongs to screen printing among the four major printing methods. Silk screen silicone prints text, patterns, etc. on other silicone products. Pad printing uses black ink, while silk screen printing uses silicone. The printing materials are fundamentally different.
Example: A logo should be printed on the spoon, and numbers should be printed on the surface of the remote control.
printing
As the name suggests, this is to print some patterns on it using silk screen printing. It's more of an effect concept.
embossed
  Some patterns are pressed out on the surface of silicone products, such as logos, text, etc. Generally, the shape is carved directly in the mold, and then pressed out directly, and then colored using other processes.
Rubber coating
Liquid silicone encapsulation | Liquid silicone encapsulation process
The above explanation is very detailed. Simply put, encapsulation is to wrap silica gel on the surface of other products and use the characteristics of silica gel to optimize other products. For example, anti-slip, improved feel, anti-aging, etc. Examples: anti-slip trays, silicone protective sleeves
Undercut
  Injection molded parts undercut molding mold structure and plastic parts design requirements are detailed here.
When the side wall of a plastic part has through holes, recesses, bosses, etc., and the plastic part cannot be demoulded, the molded part needs to be moved laterally. This structure that prevents plastic parts from being easily demolded is called undercut. The entire mechanism that drives the molded parts to move laterally is called a lateral core-pulling mechanism or a transverse core-pulling mechanism. Molds with undercut structures cannot be made by ordinary small mold factories, and the cost will be relatively high.

3M adhesive back
3M is the world-recognized number one brand in the tape industry. The process of packaging silicone products
Laser/laser engraving
In the surface treatment of silicone products, the difference between silk screen printing, pad printing and laser engraving
Why do silicone buttons use laser engraving? If you don’t distinguish carefully, the difference between the effects of laser engraving and silk screen printing and pad printing is not obvious, and the price is higher. Therefore, silicone buttons that require light transmission are usually considered to use laser engraving. Craftsmanship.
Thermal transfer
Thermal transfer silicone, thermal transfer silicone, can directly transfer single-color or multi-color silicone flower patterns and silicone trademarks LOGO to clothing, gloves, shoes and hats and other products using a heat transfer machine, with a thickness of up to 0.5MM-2MM . The transferred silicone has the following characteristics: good elasticity, strong three-dimensional effect, cannot be washed away by ultra-high temperature water, simple process and easy operation, environmentally friendly and beautiful, no marks, good adhesion, etc.
