The types of small plastic molding machines include Horizontal Injection Molding Machines, Vertical Injection Molding Machines, Toggle-Action Injection Molding Machines, and Electric Injection Molding Machines, each offering unique advantages for specific applications.
Small plastic molding machines are the key pieces of machinery in the production of different plastic parts ranging from simple pieces to advanced precise articles.
These machines are compact and highly versatile for small-scale production and prototyping.
In small scale production, a small plastic molding machine is required.
In this review, we focus on the most small plastic molding machines and the industries with the most advantages from them.
Definition and classification standards of small injection molding machines
Small injection molding machines usually refer to equipment with a clamping force ≤ 1000kN (about 100 tons). Its core value lies in precision control, rapid production and small batch flexibility. According to the structure, drive mode and function, it can be divided into the following four categories:
- According to the clamping structure: two-platen (compact), three-platen (high precision)
- According to the clamping force (core parameter):
- Small machine: <1000kN (such as 60-ton vertical machine)
- Micro machine: <30kN (laboratory grade)
- According to the drive mode:
- Hydraulic: strong power, slightly higher maintenance cost
- All-electric: 50-70% lower energy consumption, accuracy ±0.01mm
- Electro-hydraulic hybrid: balance energy consumption and power
- According to the layout axis:
- Horizontal (market share 70%), vertical, angle, multi-station
Types of Small Plastic Molding Machines
- Horizontal Injection Molding Machines
- Vertical Injection Molding Machines
- Toggle – Action Injection Molding Machines
- Electric Injection Molding Machines
Horizontal Injection Molding Machines
Features
Horizontal injection molding machines are a type of small plastic molding machines with a specific design. They have the injection unit and the mold clamping unit aligned horizontally. This alignment enhances the ease of material flow and the ejection of the molded parts is simple.
Applications
These machines are prolific when it comes to the production of small to medium plastic parts with a high degree of accuracy. They are widely used in the manufacture of automotive parts, electronic housings, and other plastic consumer goods.
Vertical Injection Molding Machines
Features
Vertical injection molding machines have the injection unit and the mold clamping unit mounted vertically. This arrangement tends to take a smaller horizontal space which and is space saving especially in small floor space facilities.
Applications
Vertical machines are highly regarded for the manufacture of small parts that demand accuracy in the measurements. They are also advantageous in systems where space is tight, likewise, needing to be very efficient.
Toggle – Action Injection Molding Machines
Features
These machines open and close the molds using a toggle mechanism and so are classed as toggle action injection molding machines. This mechanism is excellent where considerable clamping force and production of high precision and strong parts is required.
Applications
These machines are best suited for producing high-strength and sensitive mechanical and structural components.
Electric Injection Molding Machines
Features
With electric injection molding machines, electric motors drive the injection of material and the mold clamping. These machines are high precision systems and are more energy efficient, which is an advantage in applications where energy utilization is critical.
Applications
Industries like electronics and medical device manufacturing rely on electric machines for their energy efficiency and precision.
