What is injection molding tonnage?
The “tonnage” is the measure of force that is required to keep the tool closed during the injection process. This force is the main factor in determining the injection molding machine size required for producing the part.
What does an injection molding machine do?
An injection molding machine (also spelled as injection moulding machine in BrE), also known as an injection press, is a machine for manufacturing plastic products by the injection molding process. It consists of two main parts, an injection unit and a clamping unit.
What is capacity of injection molding machine?
Automatic Plastic Injection Moulding Machine, Capacity: 1 to 100 Ton/day
| Machine Type | Injection Moulding |
|---|---|
| Raw Material | HDPE, PE, PP, PVC |
| Clamping Force | 0-100 ton, 100-300 ton |
| Capacity ( ton per day) | 1 to 50, 50 to 100, 100 to 150, 150 to 200, 200 to 250 |
| Clamping Way | Hydraulic, Hydraulic & Mechanical Composite |
How do you determine the tonnage of an injection molding machine?
T = A x cf. For example, the projected area of the molded part is 150 sq/in times a clamp factor of 3 (tonnage needed/square inch from material data sheet). 150 x 3 = 450 tons needed. If you are running in a 500-ton press, try starting at 450 tons.
What is clamping unit in injection Moulding machine?
The clamping units are used to keep the mold shut against the forces developed when injection pressure pushes plastic into the closed mold. Therefore, the amount of clamp force must be at least equal to the amount of injection force. The machine sizes are determined by the clamping tonnage forces.
What is maximum daylight in injection molding?
Maximum daylight is the maximum gap allowed between the two plates, whereas; the minimum gap is the minimum permitted daylight. Example: According to the machine specification, the maximum mold height is 790 mm, and the minimum mold permitted height is 300 mm.
What are the disadvantages of injection Moulding?
Disadvantages of injection moulding
- High tooling costs and long set up lead times. Up-front costs are high due to the design, testing, and tooling required.
- Part design restrictions.
- Small runs of parts can be costly.
What are the 3 main parts of an injection molding machine?
An injection molding machine consists of 3 main parts: the injection unit, the mold – the heart of the whole process – and the clamping/ejector unit.
What is barrel capacity?
When used to denote a volume, one barrel is exactly 42 US gallons and is easily converted to any other unit of volume. As the US gallon since 1893 is defined as 3.785411784 litre, a volume of one barrel is exactly 158.987294928 litres. Using the approximate value 159 litre is about 0.008\% off.
What are the types of injection mold?
There are many different injection moulding process variations, including:
- Cube moulding.
- Die casting.
- Gas-assisted injection moulding.
- Liquid silicone rubber injection moulding.
- Metal injection moulding.
- Micro injection moulding.
- Reaction injection moulding.
- Thin-wall injection moulding.
What is the significance of L D ratio?
The L/D ratio is inversely proportional to the needed energy for a given aircraft – meaning that double L/D ratio requires only half of the energy for the same flight length. This results directly to better fuel economy in aircraft.

What is hyhybrid injection molding?
Hybrid injection (sometimes referred to as “Servo-Hydraulic”) molding machines claim to take advantage of the best features of both hydraulic and electric systems, but in actuality use almost the same amount of electricity to operate as an electric injection molding machine depending on the manufacturer.
