According to the needs of people, the use of plastic parts that have a long life and high resistance has become popular. Plastic injection molds are used to make and produce plastic parts. The basis of these molds is that after plastic is injected into them and the piece is formed, it is removed from the mold and cooled. To have a successful plastic injection process and produce a quality part, it is not enough to have a plastic injection machine with the right raw materials. One of the most important elements for plastic injection is to have a good and high quality mold. Plastic injection mold is one of the methods of production and manufacturing of plastic products and the molten plastic material is injected inside a chamber and after cooling the material according to the considered mold, the relevant part is produced and obtained. Note that in mold making, the most important and main part is the mold design, which can be used using many traditional and industrial methods.
Plastic injection mold
Plastic injection molds are a type of mold that has a product that comes out of the mold from the plastic family, for example vacuum cleaners, automatic machines, toys, etc. These types of molds are one of the most widely used molds in the world because of the type of use of the product. It must be of high quality and beauty. The output product of these molds are found in our life a lot. In the plastic injection industry, it is used for the production of plastic parts. We call the mold by which plastic parts or plastic products can be produced.
Main parts of the mold
An injection mold is used for plastic injection. This mold is often made of steel. Each plastic mold consists of several parts. But in general, the plastic injection mold has two main parts: a fixed part and a moving part that opens and closes with each injection shot so that the produced piece comes out of the mold and is ready for the next injection shot. The place where the fixed and movable parts are fixed to each other is also called the cutting boundary.
The part of the mold in which the plastic part is formed and the plastic is injected into it also has two main parts: the cavity of the mold and The core (muscle) of the mold. In order for a plastic piece to be formed, on the one hand, it is necessary to carve and create a hole, and on the other hand, there is a need for protrusions. In some cases, the mold does not consist of only one moving part (core) and depending on the shape and components of the part, it needs a slider (side movers) or an insert (metal part or other material that is pressed into the part).
Use of plastic injection mold
Electronics
From the lamp head to the monitor and keyboard, they are made of plastic cover. The plastic cover is resistant to moisture, dust and other external influences, which protects the electrical components. It also helps to increase the durability and optimal performance of electronic devices.
Pharmaceutical and medical industry
Since the introduction of plastic molding, this method has been widely used for medical purposes. , dentistry and medicine have been used. Plastic molds offer a high level of quality and accuracy, which has increased the comfort and speed of the operation in the medical field. If you work in the medical field and are looking for plastic molding, know that these molds are produced in different colors, shapes, and sizes, and disposable buckets, syringes, and serum sets are examples of these.
Beverage and food industry
Made plastic molds, in food services, for example, all kinds of bottles and bottle caps and cans for drinks and food such as yogurt, curd and sauce, various packaging And other elements play a role. But it is necessary to pay attention to the fact that the parts produced by plastic molding must be FDA approved, BPA-free, etc.
Automotive industry
< Auto parts manufacturers are the main industry that needs plastic injection molds. The inside and outside of the car components are designed from different parts, some of which require plastic molds so that the part can come out and be installed in the right place by injecting materials into these molds. All kinds of door opener handles and electric and manual lifters in all types of cars and front and rear bumpers that were produced in metal form in the past years are now examples of the use of plastic parts in the automobile industry.
Light industry
The applications of plastic molds in the production of different types of lamp lenses, types of bodies and bases have expanded to such an extent that they replace metal parts in bases and bodies and glass parts in a good and almost complete way. lenses and protectors.
The benefits of using plastic injection mold
- Increase production accuracy
- Increase production speed
- Reduce production cost to other production methods
- very strong performance in terms of resistance to impact and rust compared to other materials such as glass, metal, stone
- elimination of intermediate production steps such as polishing and painting and ...
- Enjoy diversity in use and application
