Application of In-mold Decoration Technology

 

In-Mold Decoration (IMD) is a plastic product surface decoration process. It helps people to get the desired shape and size of the part by molding the material, and also can give the external surface of the part certain physical, chemical, electrical and tactile decorative engineering properties, etc. It is increasingly applied to different products in various industries by designers. For example:


① It can give injection molded parts higher abrasion resistance, scratch resistance, corrosion resistance, antibacterial, water resistance, rust resistance, anti-magnetic, anti-static, anti-radio interference, anti-ultraviolet radiation, glossiness, smoothness, color vividness, etc.;

② It can improve the heat resistance, fire resistance, flame resistance, insulation, electrical conductivity, etc. of the extruded parts;

③ It can improve the plastic parts (plates, tubes) hardness resistance, shock resistance, luminous, reflectivity, etc.;

④ It can improve the cold resistance, moisture absorption, water resistance, adhesion, etc. of extruded parts (film);

 

IMD Example


Function of Coating

 

Coating is a substance in a fluid state. People use simple construction methods such as brushing, dripping, spraying, etc., and by self-drying or curing, can easily cover the surface of the parts firmly with a uniform film. The coating will protect the parts, decorate, mark and other special functions.

 

In addition to the above-mentioned common functions, the coatings are given special functions in six major areas as follows:


① Mechanical functions, such as wear-resistant coatings, lubricating coatings, anti-vibration and sound-insulating coatings, etc.;

② Thermal functions, such as temperature indication coatings, high temperature resistant coatings, fireproof and fire-insulating coatings, etc.;

③ Electromagnetism function, such as conductive coatings, electrostatic conductive coatings, electromagnetic wave absorbing coatings, insulating coatings, etc.;

④ Optical function, such as luminescent coating, fluorescent coating, reflective coating, etc.;

⑤ Chemical function, such as acid-resistant, alkali-resistant, oil-resistant coatings, water-resistant coatings, cold-resistant coatings, etc;

⑥ Biological function, such as anti-fouling coating, anti-mold coating, etc.

 

These special functions of the coating enhance the performance of the product and broaden the scope of use of the product, has become an essential and extremely important field of technology.

 

Application Examples

 

Let's take the example of plastic parts such as boxes and cans for household use. In the past, polypropylene plastic parts were injection molded and then labeled (plastic film) in a different workshop. Nowadays, we can get it immediately by performing in-mold labeling or marking (IML)) in the mold. Injection molding and labeling of the outer surface of the part can be done simultaneously.

 

Another example is the cell phone, which is common in people's daily life and is a necessary accessory for everyone. However, in order to improve the usability of cell phone casing, such as improving wear resistance, scratch resistance and smoothness, we need to adopt in-mold decoration process while injection molding.

 

A common in-mold decoration process used today is in-mold labeling (IML). The specific processes are:


① Opening the mold, feeding the film to the mold and positioning the film by laser at the specified position;

② Film fixation, mold closing;

③ Resin injection;

④ Pattern transferred to the plastic part.

 

The in-mold labeling process described above has the following advantages:


① Directly adhered to the surface of the plastic body, which can significantly increase produtivity;

② The delivered film is precisely positioned (controlled by laser) to meet the extraordinarily high requirements of certain trademarks. The in-mold labeling process can eliminate defective products compared to the manual coating process in the past;

③ The coating solid film used is non-polluting and meets environmental requirements.

 

In-mold decoration is an emerging science and technology that has been developing rapidly in recent years, which not only provides protection, decoration and special functions for products, but also greatly reduces labor and significantly increases productivity.

Identify Different Types of Transformer Cores, Based on Materials

  Hi guys, this is JRPanel ! In previous  blog s, we have introduced several points about High Frequency Transformer, like  bobbins  and  Flat Spiral Coil . In this blog, JRPanel would like to introduce the commonly used magnetic cores in transformers ,  based on materials.   Generally speaking, the material of the core determines the environment in which the transformer is used. A transformer that uses a core of a different material will have its performance affected, may even be non-functional.   By material, magnetic cores are generally divided into the  several  categories . JRPanel will introduce them one by one to help you understand more fully.   1. Manganese Zinc Ferrite Core Mn-Zn core is a soft magnetic core with high initial permeability (2000~15000). The higher the initial permeability, the lower the surface resistance, so it is generally used in circuits below 1 MHz. Mn-Zn core has a high saturation flux density and causes lower losses, making it one of the most desirable

The Relationship Between Plastic Nameplates and Membrane Switches

Before the 1970s, most nameplates   were made of metal materials. Today, plastic  nameplates   have been widely used in household appliances, instruments, meters, office equipment and other fields, and have become an indispensable part of electromechanical products. It not only plays the role of trademark identification, specification model, function indication, etc., but also becomes an element that reflects the appearance of the product.   With the continuous use of new materials and new processes, the surface of plastic  nameplates   is constantly improving, and it has become the crystallization of three major technologies: comprehensive surface treatment, processing and molding, and screen printing.   Plastic  nameplates   can be divided into 2 types according to their material processing methods and objects of use:   1. The injection-type plastic  nameplate   is made of ABS, PC and other engineering injection molding, and then undergoes secondary surface decoration processing such

The Main Use and Classification Methods of Transformer Bobbins

  Hi guys, this blog is still about   high frequency transformers .   JRPanel   would like to introduce you the main use of transformer bobbins and how we classify them.   In the pictures are the transformer bobbins.        Following are the main uses of that JRPanel has summarized for you:   1. The bobbins provide space for winding copper wires in transformers.   2. Wire channel in the bobbins provides path for transformer winding.   3. The bobbins help to fix the core in the transformers.   4. The metal pins in the bobbins are connected to the  PCB  after soldering, which play an important role in conducting electricity when the transformer is working.   5. The baffle at the bottom of the bobbins isolates the core from the tin stack to avoid poor volta ge resistance.       From this it can be seen that the importance of bobbins in transformer is extraordinary.   After understanding the main uses of transformer bobbins,  JRPanel  is to introduce its common classification methods.   Fi
