Small household plastic injection machine
Disadvantages and advantages of the all-electric injection machine
The advantages of the all-electric plastic injection machine are:
1. Due to the complete control of the process and the very high repeatability of the device, which is done by separate servo motors, the production process is done with the least amount of materials and additives, which will greatly reduce the waste of the operation.
2. Due to the separate operation of the motors, different tasks of the device are performed simultaneously. Finally, the production cycle in all-electric devices will be much faster than other devices.
3. Suitable for use in a clean room where the level of environmental pollution should be as low as possible.
4. Another advantage of the all-electric device is the absence of sound and engine noise below 70 dB. Not needing filter and hydraulic oil is one of the other advantages of proper maintenance.
5. By using the servo motor, the energy consumption of the fully automatic injection machine is approximately 50 to 75% lower than the hydraulic injection machine.
6. Due to the small leakage, the possibility of contamination of materials and surfaces has been greatly reduced.
7. Suitable for the production of medical parts such as syringes and petri dishes with the highest accuracy.
8. Due to the use of digital control during the process, the all-electric injection machine does not need to apply occasional adjustments that are quite naturally used in hydraulic injection machines.
By starting the process with the desired conditions, the production process will be completed without any kind of supervision and with full repeatability. Eliminating hydraulic hoses and valves means that there is no need to calibrate the device.
There is another type of these devices, which is called a manual plastic injection device, and it consists of a small cylinder and piston and a manual lever, which are used to melt and inject plastic. This device uses hand power to provide injection pressure and therefore has a very limited injection pressure. The manual plastic injection machine is mostly used for DIY (do-it-yourself) project enthusiasts, crafting and manufacturing, or entertainment.
Note that desktop, home, and manual plastic injection machines are rarely effective for producing complex plastic parts. Also, these devices are not suitable for mass production and are only profitable in a few businesses.
Buying a home plastic injection machine
The plastic injection machine is divided according to its efficiency. Its industrial type is effective for producing large plastic items such as tables and chairs. Semi-industrial is suitable for workshop environments and has better performance than other models.
The small or household plastic injection machine is light in weight and small in size. The industrial machine works on high voltage electricity while the small machine also works on municipal electricity. The structure and production method of these devices have also caused it to be divided into two types, simple and complex. Complex devices are automatic and are the best type of this product.
The simple device is also less complicated and its price is more reasonable, and its simple type is produced in different designs and models. Considering the fact that this machine is small and simple, it has the same desired efficiency and produces the product with great precision. Thermoplastics are high-quality and first-class materials that are used in making all kinds of plastics because of their high strength. Another type of material is called nylon, which is resistant to chemicals and is effective for making car tools.
Types of home plastic injection machine molds
1. One-piece molds: These types of molds are the simplest type of molds that are usually used to produce parts with simple shapes. In these molds, there is only one section where the molten plastic is poured.
2. Two-stage molds: Two-stage molds consist of two separate sections that interact to produce more complex parts. These types of molds are usually used to produce parts with special and complex features.
3. Multi-hole molds: These molds are designed in such a way that they can produce several parts at the same time. These types of molds are very suitable for producing high-volume products in a short time.
The difference between domestic and industrial plastic injection machines
Home or desktop plastic injection molding machines differ greatly in size, power, usability, and capabilities from industrial plastic injection molding machines.
These machines are significantly smaller and more compact, so they can easily fit into the limited space of a home workshop or laboratory. The design of these devices is such that even non-professional users can easily use them.
The tonnage of home devices is usually between 50 and 500 kg. The injection volume of these devices is usually between 5 and 20 cubic centimeters.
The main components of the household plastic injection machine
Injection Unit
▪️Screw: melts the plastic and injects it into the mold.
▪️Heater: heats the plastic material and melts it.
▪️Thermal Bands: to maintain a constant temperature of the plastic material during the injection process.
Unit Clamping Unit
▪️Clamping System: Closes the mold during injection and withstands the pressure.
▪️Clamping Plates: The mold is placed between these plates. Display Panel: To display and set parameters.
conclusion
Home or desktop plastic injection machines are known as suitable tools for training, testing and production in small environments. Due to the increase in the need for fast and flexible production, the use of these devices as a developed tool in the industry for small spaces or personal and laboratory work is economically justifiable. Also, for earning income, these devices can be a stable source of income, and for this reason, they have been given attention.
