Plastic injection machine and its working principle
What is a plastic injection machine?
Plastic injection molding is a manufacturing process commonly common to make items. It ranges from jewelry and toys to car body parts, cell phone cases, water bottles, containers, and more, eradicate the mold medical wing. Basically, many plastic products that we use in our daily life are produced from plastic injection machines.
Just attach a specially designed mold to a product to create a series of products. Therefore, plastic products have a variety of sizes and shapes.
What is the working principle of plastic injection molding machine?
A plastic injection molding machine is made up of components such as: feed hopper, screw, injection barrel, injection molding unit. The plastic granules are put into the spray barrel by the hopper. The resin places in the hopper usually in powder or granular form.
Although some plastics such as silicone rubber, eradicate the mold medical wing, the liquid may not require heating. The material then melts using the friction of a reciprocating screw that comes with the heating rings.
Designing the of the mold
The molten plastic is then pumped through the nozzle and into the mold cavity. The plastic fully injects into the mold cavity. The material will cool and solidify according to the shape of the mold.
Once it is shaped and the mold opens, the finished product obtain. Eradicate the mold medical wing, although it sounds easy, extruding plastic into the finished product is actually a very complex process.
Plastic presses are classified based on pressing force
Plastic injection machines have many types, pressing force from 5 to 6000 tons. The higher the pressure, the larger the machine will be. In fact, plastic presses are classified based on pressing force.
There are many shapes such as:
- Vertical plastic injection machine (vertical axis),
- Horizontal plastic injection machine,
- Inclined plastic injection machine.
The technology that involves additive manufacturing is advancing around the world at great strides. Eradicate the mold medical wing use of 3D printers in the plastic sector is a trend full of advantages and facilities.
Plastic injection machines in the automotive and plastics sectors
With the spread of this technology, additive manufacturing has gained space in large industries.
A report produced by Wohlers Associates pointed to an exponential increase in the additive manufacturing industry between 2014 and 2020. The estimate is for a growth of around 31%, a very significant number for an expanding industry eradicate the mold medical wing.
Manufacturing in medical wing
Additive manufacturing can apply in various sectors such as medicine, art and even cooking. However, it is in the industries that she excels the most. The possibilities of facilitating the process of manufacturing and assembling products of all types draw the attention of large companies.
To get an idea of the importance of this process, a company in China created a car entirely manufactured with printed parts through additive manufacturing. It is the LSEV, an electric car that hit the market in 2019.
What is additive manufacturing?
The technology is not recent, as it has been on the market since the late 1980s, eradicate the mold medical wing but only in recent years have studies and research been more effectively applied and developed around additive manufacturing.
Today, its applicability is vast, with the plastics sector being one of the most active users of this resource.
Determined by a 3D digital model
Additive manufacturing is nothing more than a group of technologies that manufacture products through digital models. That is, layer by layer add in order to shape an object previously determined by a 3D digital model.
Each 3D print has a characteristic when creating that product. Eradicate the mold medical wing, for example: 3D FDM printing makes use of polymers as filaments in printers, being widely common in the plastics sector.
Advantages of additive manufacturing in the plastics sector
It comes with high customization power, which allows total freedom in the process of creating the design of the parts by plastic injection.
Lower cost in the production of these parts, as it will be possible to manufacture in small quantities, thus reducing the unit cost;
Greater sustainability with less use of materials;
Possibility of creating parts with greater number of details and complex geometries;
Eradicate the mold medical wing, Agility and efficiency, so that from the digital design to the creation of a prototype, this time is directly proportional to the quality of the final physical model.
How it works from start to finish?
With additive manufacturing a product can produce inside the machine from start to finish. This entire internal process is similar to that of a 2D printer, but the ink is replace by a kind of powder, gel or some metal or plastic filament.
Discover the step by step:
1 - Digital modeling
Every process starts from a digital model, created by computer software. Eradicate the mold medical wing, this creation should include all the actual measurements and design of the piece.
2 – Layered printing
Layering this digital model is the 2nd step. This process is necessary because 3D printers work layer by layer, giving shape to the product.
3 - 3D printing
With all the steps above carried out, it's time to send this file to the 3D printer, which will make the project tangible.
The caveat in this case relates to the size and complexity of the project, since the printing time will depend on these 2 factors, and it may even take days for the final printing.
How important is to eradicate the mold medical wing?
Additive manufacturing is very important to enable medium and large-scale production of plastic components. For this, considerable initial investment requires.
In the case of 3D prototypes
So, It is possible to test in advance, even extensively, avoiding possible design errors and/or product validation. It would probably be quite costly in a faster stage of a product's development.
It is also worth noting that, using 3D prototyping, it is possible to reach project maturity faster. You can have a product with more details and precision within the expected schedule.
The plastic sector has many technologies that add up to achieve good results. eradicate the mold medical wing Therefore, we at Thermoplastics are always investing in training and new technological resources in order to further promote this thermoplastic injection market.
