IMD-In-mold decoration

In-Mold Decorationshort nameIMD, refers to the in-mold decorative insert injection molding, which is a technology that attaches or transfers the printed film material to the surface of the workpiece while injecting the workpiece in the mold. Compared with traditional water transfer printing, in-mold decoration technology can solve the problem of pattern alignment on the workpiece, the lines are not easily deformed, and the finished product has the characteristics of corrosion resistance and high scratch resistance. Because the process is more environmentally friendly, many electronic products haveIMDTo increase the diversity of product appearance, it is widely used in automotive interiors, home appliance panels, electronic communication chassis and other products.

This process is further divided into INS (in-mold insert), IMR (in-mold transfer), IML (in-mold labeling), and IMF. The following is an introduction:

1. INS (Insert Thermoforming film to Molding) After cutting the printed film, it can be directly injected or heated to form a 3D shape, embedded in the mold cavity and injected with plastic. 2.IMR (in mold Rolling) is also known as plane transfer, in-mold transfer, and the appearance of the product is limited by the height of the curved surface and can only be made as a slightly curved product.
3.IML (in mold labeling) plane integrated molding technology, 2D plane, printing + punching + injection.

4. IMF (in mold forming) surface integral molding technology, 2.5D~3D three-dimensional modeling, printing + high pressure + punching + injection).

INS-In-Mold Insert Forming-Introduction

 INSWhat is it? 

What is INS?

• That is, Film Insert Molding, using thermoforming or high pressure molding, to stretch the transferred film (usually 0.5mm thick) for three degrees, and then cut out according to the shape of the product The insert is then injection molded by placing the insert accurately in the injection mold cavity.

• INS sheet: the material is mainly ABS, ABS/PMMA

 INSSimple production process 

The base material of INS: the material is mainly ABS, ABS/PMMA

INS simple production process  

1. Film (PMMA printing + ABS bonding) → thermoforming → cutting into inserts → embedding injection molding → finished product
2. ABS UV embossing and coloring → thermoforming → cutting into inserts → embedding injection molding → finished product

→Heating→Blister molding→Cutting into inserts→Embedding the mold→Injection molding→Finished product

ABS UV embossed coloring

→Heating→Blister molding→Cutting into inserts→Embedding the mold→Injection molding→Finished product


 INS (In-Mold Insert) Product Application 


IMR-In-mold transfer-introduction

In-mold transferIn Molding Roller, referred to asIMR, is to print the designed pattern on the release transfer film, and preheat the release transfer film, vacuum forming and then injection molding, after the completion of the patterned ink will be separated from the film, leaving the ink and protective layer, That is, the finished workpiece product with texture.


IML- In-mold labeling - Introduction

IML (in-mold labeling) is a laminating film printed with graphics or logos. When the mold is closed for injection, the film surface is attached to the surface of the injection-molded workpiece. Compared with traditional labeling, the advantage of the finished product is that the label and the plastic are integrally formed. , to achieve a more perfect fit.


IMF-In-Mold Inserts - Introduction

IMF is suitable for 3D products. The method is to pre-form the printed IMF film in a high-pressure blister molding machine, then cut the pre-formed film, insert it into an injection mold, and complete the injection molding process. The finished product is divided into the upper hardened transparent film (common materials are PC, PET, PMMA, etc.), the middle printing pattern layer, and the back plastic layer, because the ink is different from the first two, which are on the surface of the product, but on the middle layer of the product. , This technology can ensure the excellent color fastness and scratch resistance of the product.
