In-mold film
1 In-mold film process application
In-mold film, also known as in-mold labeling (IML), is a kind of in-mold decoration process. It is a plastic decoration technology that uses the temperature, pressure and a certain time of plastic molding (including injection molding and blow molding) to simultaneously attach functional layers, structural layers or decorative layers in the mold.
OPP in-mold film
1 Concept of OPP in-mold film
OPP film, a film made of polypropylene, is scientifically called polypropylene film. It is usually referred to as PP film.
OPP film is colorless, odorless, tasteless, non-toxic, and has high tensile strength, impact strength, rigidity, toughness and good transparency.
Due to its excellent properties, OPP film is widely used by thermal transf

1 Application of plate thermal transfer process
At present, the plate thermal transfer process is mainly used on plastic plates.
According to the different transfer processes, the commonly used plate thermal transfer processes can be classified into two types: ordinary thermal transfer process and thermal transfer derivative process - in-mold laminating proc
1-Concept of IML
IML is a kind of thermal transfer film. It places the prepared film on the specified position of the substrate and forms a layer of exquisite patterns on the surface of the product through the heat and pressure of the blow molding equipment.

【Thermal transfer analysis】Three things to note about in-mold stickers
1-Dust
In-mold stickers are a type of thermal transfer technology. The raw materials, processes, and application methods used are quite different from ordinary thermal transfer processes. What should be paid attention to in-mold stickers during production and processing? The following is a brief introduction for you.

Five steps in the injection mold production process
Injection mold production can be roughly divided into the following steps:
1. Process analysis of plastic products.
Before designing the mold, the designer should fully analyze and study whether the plastic product conforms to the working principle of injection molding processing, and needs to carefully negotiate with the designer of the produ
What will affect the precision of injection mold processing?
When our injection molds are being processed, how can the precision management of molds be improved? First of all, we need to know which issues directly affect the precision of injection mold production and processing.
1. Dimensional accuracy
Refers to the degree of conformity between the actual working size of the parts after product
Interpretation of the causes of injection mold problems
(1) Ejection should be stable and balanced, such as the total number of ejector pins, the cross-sectional area, the demoulding slope, and the cavity surface should be smooth enough to avoid residual stress concentration and cracking caused by external force.
(2) The structure of the part should not be too thin, and the transition part shou
