Do you want to buy mini plastic injection machines in Russia?

What equipment is needed for the production of plastic products?

Everyone who is involved in construction or any other economic processes knows that without pipes, insulation, containers, hoses and other things, almost nothing can be done on your own. In addition, all these plastic products have fairly good strength and are not particularly susceptible to environmental influences. They never rot, are light in weight and highly elastic.

So, what basic mechanisms will you need for the successful and high-quality production of plastic products:

• electric motors that will supply electricity to all equipment;
• machines for automatically loading raw materials into extruder cylinders;
• extruders, which have one or two parallel worm screws. They are used for heating and mixing polymer materials;
• A mandatory unit for forming a future product is a forming head, which is attached to the extruder;
• form pulling device;
• cooling system;
• a separate device for measuring the dimensions of finished products;
• a separate device for packaging finished products.

You can also purchase an automatic device that will deliver products to a specified location. It can be controlled using a remote control.

Equipment for making plastic items

To produce plastic products you will need a ready-made production line or a separate machine. Any master can build it at home.

Extruders are a huge set of machines that facilitate the production of foam and window profiles, pipes and plastic slates, tubular and sheet films, and polymer sheets.

The main structure of the machine is the excuder. The extrusion line is made up of a set of additional mechanisms. The production operates in automatic mode, it is regulated by a specific program.

An injection molding machine is a machine for injection molding plastic. The pre-prepared mass is put into molds and cooled. As a result, a finished piece product is formed.

Automatic thermoplastic

About 75% of all plastic products are made on these machines. This technique promotes the formation of rather complex shapes that fit the required dimensions with precision. The equipment has the ability to work with all types of this material.

The unit includes a drive, a material preparation module, an automatic control unit and a mold closing and opening module. Injection molding equipment is quite expensive and includes many innovative solutions.

Blow molding plants for plastic products

Special blow molding equipment is used to produce products with thin walls (disposable cups, bottles, etc.). It works according to this scheme: the plastic is heated and then the product is formed using blowing.

Extrusion blow molding machines are used to produce a wider range of products. The production process is controlled by a microsystem. All machines of this type are divided by the type of heads, number of streams and posts.

Thermoforming machines are used to produce continuous film (sleeves). The thickness of this product varies. Most often used for the production of disposable tableware.

An interesting fact is that one device can be used for different processes. You won’t have to buy a lot of cars that will require additional territory.

A striking example is systems for foaming plastics. With their help, you can perform this action, but also additionally produce:

• film;
• insulation structures;
• mesh, etc.

Using a pipe production machine, you can create a product of any diameter and thickness that will be used in the water or gas supply of houses, the functioning of the sewer system, and space heating.

Using blow molding or injection molding tools, you can make a variety of containers with a wide variety of depths, diameters and thicknesses. They are usually used in the chemical or food industries. You can also create unrivaled finishing products from thermoplastic. It has a fairly aesthetic appearance and high strength.

Special equipment

Blow molding machines are designed for the production of hollow vessels that have thinner walls: barrels, canisters and bottles.

This unit helps to heat the material and blow mold it. This method is combined with injection molding in one injection blow molding machine. Extrusion blow molding machines combine the following techniques: extrusion and blow molding.

In this case, it is possible to produce a wider selection of products than blow molding machines. All processes are controlled by a microprocessor.

Machine classification:

• by the number of streams;
• by type of heads;
• by number of posts.

A tabletop manual press for plastic injection is designed for the production of medium-sized products in small batches. This machine weighs no more than 15 kg. Fits perfectly on the table.

If you purchase it in a store, then in some cases the table itself is included in the kit. A tabletop plastic injection molding machine is needed to produce parts of new designs as an experiment.

Additional machines to improve the production line

If production takes too much time and effort, you can purchase additional equipment for the production of plastic products, which will help speed up the process and make it less labor-intensive:

• drying for products;
• loader of materials or finished products;
• mixer;
• hole crusher;
• conveyor for finished products or material for a subsequent processing step;
• conveyor for packaging and additional checking of products.

If you do not plan to start a huge business producing plastic products, you can purchase several mini-machines that will make certain parts in small quantities. They will not take up much space and will provide an opportunity to earn money for expanding the enterprise.

To install a mi-line, you will need ordinary tables on which fifteen kilogram machines can be placed. There are also separate machines for the production of experimental parts, which will later be produced on larger equipment.

Manufacturing method

Algorithm for selling any type of plastic products:

• formation of an unambiguous chemical composition;
• gas is introduced into the polymer environment;
• the resulting mass is given the desired casting;
• installation of the final form.

At the initial level, different components are mixed to obtain a plastic substance. After this, gas is added to the polymer in a specific way: either by introducing fast-boiling substances or by mechanical foaming.

They disappear when heated or introduced under gas pressure. The manufacturing method depends on the type of polymer and products. There are several ways to make plastic products:

• the presence of castings - the plastic mass is turned into liquid and poured into various forms similar to the finished product. As a result, quite a lot of items are formed: dishes, stationery;
• thermoforming;
• compression molding - during the manufacturing process, the required amount of material is placed in a mold, the halves are connected, and then a finished part is formed;
• encapsulation;
• vacuum forming - the required shapes are obtained from sheets of plastic under different pressures;
• layering molding;
• blowing - the heated mass is poured into the mold. The mold closes and fills with air. The polymer spreads over the entire inner surface in equal quantities;
• extrusion - the mass is softened and suppressed through a matrix, which forms the required shape;
• compression molding - the workpiece is compressed inside the mold, excess material exits through the cracks.

Use of raw materials for the manufacture of plastic products

Regardless of how expensive and high-quality the equipment is, products may be defective. It is best to buy raw materials from trusted manufacturers with a good rating and experience in the construction business.

In addition to carefully selecting materials, you also need to keep your employees in mind. Such production will require at least a dozen workers, who will need to explain the process in detail from the very beginning. And of course, a technologist, without whom nothing can even be started. The cost of his services will require a lot of money.

Types of plastics and raw materials

The following types of plastics are used for the production of polymer products:

• polyethylene;
• polystyrene;
• polyethylene terephthalate;
• polyvinyl chloride;
• high and low pressure polyethylene;
• polypropylene;

The quality of plastic manufacturing is determined by the choice of raw materials. Even the best plastic injection molding equipment requires reconfiguration when the starting material manufacturer changes.

Otherwise, the quality of the products produced will be completely different.

Plastic Products Manufacturing Process

The main thing in the process of creating plastic products is the organization of the process and the precision of execution. It is important to come up with your own scheme and sequence of work. It is worth carefully studying how everything happens:

• the very first stage is the release of gas into a previously prepared polymer medium;
• after this the combination of rubber or plastic takes place;
• mixtures are subject to special technical treatments and are prepared for the creation of finished products.

For a century now, people have been giving preference to plastic products over polyethylene ones. They are resistant to sudden temperature changes and internal pressure. There is also a separate classification of plastic products that are filled with gas. They are usually used to insulate buildings. These are foam plastics and foam plastics. For example, polystyrene foams have closed pores, which allows them to retain heat. But porous plastics, on the contrary, are open.

Plastic molding at home

Before starting the process, it is necessary to prepare the area. A table is perfect for equipment such as a mini injection molding machine. This unit weighs about 50 kg. Such a machine will require 20% of the maximum electricity for 10 hours of operation.

For example, if the power is 1.7 kW, then in 10 hours 3.4 kW will be required. The machine is designed to work for one person. In the process of molding plastic products, it is necessary to comply with all safety and sanitation standards of the industry.

It takes 40 seconds to produce one product, which means that specialists can produce about 100 parts in an hour.

In addition, you will also need additional equipment - a crusher.

Plastic crusher

A mini plastic injection machine injects the mass directly into the part. If you completely follow the instructions and follow all the rules of casting, there is practically no defect.

Often craftsmen begin home production by using thermoplastics - the material is not easy and requires a scrupulous attitude. Casting from this material involves the use of several preparatory stages:

• tremoplast must be cleaned from the upper layers of contamination;
• It is necessary to start melting at low temperatures, increasing the degrees by an equal amount;
• To cool the mold, it is necessary to apply a sharp temperature difference.

It is difficult to work with such material, so it is better to hire an assistant at home. This solution will help to carry out all operations on the machine evenly, as well as to cool the product in a timely manner without breaking the standard shape.

What should a room be like for the production of plastic products?

There is no need to be too clever with the construction of this room. It must only meet all standard standards and contain devices familiar to this business.

The cost of the cars is usually low, and you don’t have to pay much for the territory. In order for the plant to contain all the required communications in the required quantities, you can build a building measuring 50–200 square meters, which is not very much. But there is one caveat: a warehouse can occupy a very large area. Despite the fact that plastic products are light in weight, their sizes are quite large.

Don't forget about the people who may be harmed by plastic production. When looking for a site to build on, it is better to avoid residential areas.

The premises require mandatory protection from certain environmental factors. These are excessive moisture, strong winds, sand storms, thieves and persons without a fixed place of residence.

It is best to keep any granular materials in rooms with low air humidity and warm temperatures. After all, it is this factor that affects the quality of future products.

To avoid problems with the law, you must obtain permission from several authorities:

• sanitary and epidemiological station;
• district or local government;
• state supervision;
• fire inspection;
• gas inspection;
• electricians.

If you have enough funds and knowledge, the construction and start of the plastic products production process will take no more than three months.
