The basis of the machine is an extruder. All additional components only complement the device. The principle of the device is based on automation, controlled by a given program.

Devices for the production of plastics under pressure

Such equipment for the production of plastic products involves pouring the finished product into special molds, where it undergoes cooling. The result is a finished piece product. Most of the elements made of plastic are produced on such machines. The technology makes it possible to create complex shapes corresponding to the desired dimensions, multi-color details, hybrid, foam-based, and others. The injection molding machine is designed for the production of various types of plastics.

Such a device is also used as equipment for the production of thermal insulation products from plastics.

The machine design includes:

• Module for preparation of raw materials;
• Module that regulates the closing and opening of forms;
• drive unit;
• Automated control unit.

This device has a high cost and contains many modern solutions.

Blow molding machines

This equipment for the production of plastic products , plastic is used for the manufacture of hollow containers with thin walls. For example, canisters, barrels, bottles up to 5 thousand liters are produced.

The blow molding device heats the material and gives it a shape by blowing. Often, this method is combined with injection molding in a machine with a combined configuration. In this way, PET containers are made.

Extruded Blow Molding Tools

This equipment for the production of plastic products, as well as rubber, produces a synthesis of blowing and extrusion. It can produce a larger range of products than blow moldings: fuel tanks, bumpers, pallets, seats, barrels, buckets, toys, bottles for tomato and milk, bottles for cosmetics. All processes are subject to careful monitoring by means of a microprocessor.

Equipment for the production of plastic and rubber products is divided according to:

• From the configuration of the heads;
• From the number of posts.

Package Contents

Equipment for the production of plastic products includes:

• An extruder, through which plastic is converted into a homogeneous mass of soft consistency.
• Extrusion head located at the outlet of the machine. A mass passes through it. The head is of different design (single-hand or multi-strand, angular or straight-through).
• The mass that passes through the extruder head and forms the basis for the formation of the sleeve or tube blank.
• The blowing part is the main unit of the device. Compressed air is supplied through the needle, nipple or mandrel. The form is inserted and closed. The blank is cooled, after which the mold is opened and the finished product is taken out. Here, the welded joint is also cleaned.
• Composition of the extrusion blowing device is complemented by a compressor and a cooler.

Thermoforming units

Such equipment for the production of plastic products is intended for the production of products on the basis of a film, the supply of which is carried out in an uninterrupted regime. The thickness and consistency of the material can vary. With the help of this device, products such as disposable containers, paper or plastic glasses are obtained.

Principle of work of the device

The material is heated to 140 ° C, the product is blown from the roll. Usually a film is used in the production, the thickness of which is 100 micrometers.

By the type of similar machines are divided into tape, rotary, turret, single-position and multi-position. The units of turret and rotary type are used for molding. The process takes place automatically, manually or semi-automatically.

Additional devices

In addition to the main units, in the process of manufacturing their plastic products, devices are used that make the work much easier:

• Drying devices;
• Loaders;
• Mixers;
• Devices for crushing;
• Conveyors;
• Devices for collection of oblov.

Mini devices for the production of plastics

Mini equipment for the production of plastic products is used to obtain the product in small batches. As a rule, single or multi-local forms are used. The weight of such a device is 15 kg. It is easily placed on a table of strong construction. That's why such a device was called desktop. Some units are accompanied by a small table.

The models with a drive on an electrical basis and an automated clamping module are much smaller. Such small machines are used to obtain experimental details for new equipment.

Semi-finished products of plastic with their own hands

Scrap of plastic can be found everywhere. At home, old, unnecessary things from plastic are always gathering. There are many bottles and packages on the street. Those people who like to create something with their own hands, there may be an idea to use all this for the production of plastic products at home, to subject the residue to grinding and remelting.

But a beginner master to resort to such actions is not recommended, since each kind of plastic has its own characteristics, and the melting point for them requires different. In addition, usually in factories and factories, the parts are cast by means of specialized installations, in which a strong pressure is maintained.

Even if you collect pieces of plastic and subject them to grinding and melting, then there will be bubbles. The best advice is to buy in the building materials store plastic in liquid form, which will serve for the manufacture of parts that are inferior in quality to the factory ones. Replacing the plastic can serve as rubber.

Also you will have to purchase:

• Silicone;
• High capacity;
• Lithol.

If you decide to produce something from plastic, then work in a closed room. Vapors from plastic have toxicity.

We make the form

Equipment for the production of plastic products at home includes a master model, the basis of which can be anything.

You will be approached:

• plasticine;
• gypsum;
• tree;
• Paper and other materials.

The model of the part to be cast must be coated with lithol or another lubricant. Then make a shape. Silicone is very popular. Everything is clear, since it is very simple and convenient to work with such material.

Important nuances

• Silicone is of two types: for pouring and coating.
• Each species has its own coefficient of elongation and the degree of viscosity. As for the first indicator, for the manufacture of plastic we apply silicone with an index of up to 200%.

Pay attention to the viscosity of the material

Pay attention to the viscosity index of the material. The lower it is, the more accurate the shape.

This point is especially important if you work with material such as silicone filler. Also take into account the duration of polymerization. If you use casting silicone, the master model should be placed in a flask (its base can be made of steel or bronze), and then pour silicone.

The lubricant is carefully applied with a brush. This takes into account all irregularities. Silicone should be allowed to cool down, after which the master model is extracted.

Opoka is a container of metal. It should be little more than a master model.

Casting parts

This process is directly dependent on the basis of the production of the part. Resins on a polyester base and plastics of a liquid consistence are attractive in that they do not undergo melting. Their difference consists in the exponent of the coefficient of viscosity and lifetime.

Step-by-step instruction

• Take a mold for casting and thoroughly cleaned. It should not be wet or dirty. All residual materials remaining after preliminary work are deleted.
• If necessary, you can change the color of the composition. To this end, a droplet of paint is added, but it should not be water-based (the paint is incompatible with liquid plastic).
• There is no need for degassing. Plastic injection of the house from the outset provides for a short life of the substance. Bubbles of small-sized products are displayed manually after filling.
• All components are thoroughly mixed and poured into the template slowly with a thin trickle. The fill should be continued until the mixture is filled with the entire volume and some portion of the channel for casting. After passing the degassing procedure, the volume of material will decrease and become required.
• To obtain a high-quality model from plastic, subject the template to gradual cooling. Clearly follow all instructions.
