Comment les fournisseurs de moulage par injection classifient-ils les plastiques de moulage?
Quelle est la différence entre le moulage sous pression et le moulage par injection?
Aperçu et fonctionnalités
Le moulage par injection est l'une des meilleures méthodes de fournisseurs de moulage par injection . Matériaux tels que la résine synthétique chauffée et fondue. De même, envoyé dans un moule. Et puis refroidi pour effectuer le moulage souhaité.
Comment les fournisseurs de moulage par injection définissent-ils le moulage par injection?
It is called “moulage par injection“. Because it resembles the injection of liquid with a syringe. The process flow starts from “melting” the material. Then “flowing”, and “finishing”.
With injection molding, les fournisseurs de moulage par injection l'can generate various shapes of parts in large quantities. Therefore, it is used in a wide range of products including daily necessities.
What is plastic?
Plastic is a synthetic resin. It comes mainly from petroleum. It is a solid that is artificially shaped into a useful shape. Resin is the main material in it. However, rubber, paint, adhesives, etc. are excluded
When plastics were discovered in the 19th century. They became popular because of their ease of processing.
Metals have been used since BC. But it has been more than 100 years since plastics were put into practical use and spread. Compared to metal, it can be said that it is a new material. Recently acquired by fournisseurs de moulage par injection.
How do injection moulding suppliers Classify plastics?
Although there are various classification methods for plastics. They can be roughly divided into:
- thermoplastic resins
- and thermosetting resins.
Thermosetting resin
A resin that has the property of undergoing a chemical reaction. And hardening when heated. It has the property that once it hardens. It will not become soft even if heat is applied.
Therefore, it is suitable for use in high temperature environments. And in situations where heat resistance is required.
For example, there is a plastic ashtray. Which is made of thermosetting resin.
It’s a cookie-like image. That doesn’t change shape when placed in a mold and baked.
Pros
- Excellent creep characteristics Cons
- Cannothave complicated shape
- Molding cycles are long
- Since it has good fluidity, it easily causes burrs
The main les fournisseurs de moulage par injection l'thermosetting resins are:
- phenolic resin
- polyester
- Diallyl
- Epoxy
- melamine and urea
Originally, thermosetting resin products were the mainstream for plastic molding. But now thermoplastics are becoming the mainstream. However, there are many things that can only be thermosetting.
So, they will never disappear. Although it is a niche in the market. les fournisseurs de moulage par injection l'are pursuing the possibility of new thermosetting resins. Such as applications as a substitute for metals. As a manufacturer with strong thermosetting properties.
What properties injection moulding suppliers provide?
The design of resin injection molded parts has various characteristics. And roles for each part. Subsequently, the materials used also have advantages and disadvantages.
So, it is necessary to guide them well. It can be very tricky. But following a few simple rules can get you through the difficult design challenges.
For example, in injection molding, the following factors are generally problems when designing parts.
- Clip and snap fit
- Living hinge
- boss
- Characters on parts
- Two-color molding
injection moulding suppliers major industries
les fournisseurs de moulage par injection l'are an essential part of our lives. There is a great possibility that injection molding is involved in the devices you are reading here.
- Smartphones
- téléphones portables
- personal computers.
Many parts made by fournisseurs de moulage par injection are used in automobiles. As well as electric appliances. Such as:
- Téléviseurs
- machines à laver
- and printers.
“Injection molding” is used to make various objects. That you see and use. Such as:
- DVDs
- Blu-ray discs
- handles for drivers and scissors
- and controllers for video games.
Injection molding is the most used plastic molding
Les plastiques sont désormais monnaie courante dans nos vies. C'est tellement évident que lorsque vous utilisez le produit, vous ne pensez même pas qu'il est fait de plastique. La gamme de son utilisation est large. Et il est utilisé pour la plupart des objets de notre chambre.
les fournisseurs de moulage par injection l' utilisent it in everything from everyday appliances. Such as:
- Téléviseurs
- machines à laver
- Imprimantes
- téléphones portables
- bouteilles de thé en plastique
- contenants de shampoing
- ciseaux, poignées et conducteurs.
Bien que les plastiques soient comme l'air. Savez-vous que la plupart des produits en plastique sont fabriqués par moulage par injection?
Récemment, les imprimantes 3D sont venues sous les projecteurs. Et le terme moule est utilisé en comparaison avec les imprimantes 3D. Pour le dire plus simplement, il peut être plus précis de dire «moulage par injection et moulage».
Un tel moulage par injection est une entité fréquemment utilisée. On dit que c'est le roi du moulage en plastique.
Features of injection molding High quality and mass production
As mentioned above, injection molding is a plastic molding method used in the manufacture of all products.
However, the manufacturing method and features are known only to fournisseurs de moulage par injection. But the principle is extremely simple. To put it simply, it is a method of melting plastic at a high temperature of about 200 °C. Pushing it into the mold and cooling it to solidify.
What kind of shapes injection moulding suppliers can make with injection molding?
complicated shapes can be made with high quality mold. The greatest merit is the good productivity. Due to the modern modern injection molding machines, plastic products can be produced at surprisingly fast speeds.
The impact of injection moulding suppliers method on molding products
Depending on the type of product. A faster product can be produced at a rate of one in a few seconds. It can be said that it is a very efficient molding method. It is a symbol of fournisseurs de moulage par injection mass production system.
Conversely, if the sales amount above a certain amount cannot be expected. It can be said that it is a molding method that is difficult to use. Because the cost of manufacturing the mold is high.
Let’s take a closer look at the mechanism of injection molding.
How injection molding works Plastic syringes?
Le moulage par injection est divisé en deux parties. L'un est un dispositif d'injection. Cela fait fondre les matières premières plastiques et les verse dans un moule. Ce dispositif d'injection est simplement une seringue en plastique. L'autre partie est un dispositif de serrage de moule. Cela durcit le plastique fondu et enlève le produit.
Ce dispositif de serrage du moule a un rôle de refroidissement du plastique fondu. Le moulage par injection est essentiellement un procédé de moulage constitué de ces deux parties. Ici, nous allons d'abord présenter le mécanisme du dispositif d'injection. Quelle est la partie de la seringue.
Quelle est la différence entre le moulage sous pression et le moulage par injection?
les fournisseurs de moulage par injection l' disposent de several ways to process parts. Die casting and injection molding are the most suitable processing technologies for mass production of parts.
The two use molds to produce the parts. But they are similar and have distinct differences.
First of all, regarding die casting, die casting is a technology. That manufactures parts using molten metal. Mostly aluminum alloy using a mold.
Die casting uses metal molds to manufacture parts. But it belongs to the technology called “casting”. Because the material used is metal. Technology that cools products by applying high pressure.
On the other hand, injection molding is a technology. That melts plastic. And injects it into a mold at high speed. Then cools and solidifies it to produce a product.
injection moulding suppliers conclusion
The major difference between these two processing methods is the material. One uses aluminum alloys and magnesium alloys to produce products. The other uses plastic resin to produce products.
De plus, la température à laquelle le matériau est chauffé est différente. Il n'y a presque pas de différences majeures dans les formes. les fournisseurs de moulage par injection l' peuvent le fabriquer just by using different materials. Even when using a mold to manufacture products.
Il existe également des différences dans les produits fabriqués. Les machines de moulage sous pression produisent:
- moteurs automobiles
- appareils ménagers,
- et d'autres produits qui doivent être en métal.
Il est préférable d'utiliser la meilleure fournisseurs de moulage par injection technology in the right place.
