Oil tank capacity for injection molding machines is one of the parameters of plastic injection molding machines.
The oil tank capacity of an injection molding machine can range from tens of liters to thousands of liters, therefore, there is no fixed standard specification, but it is determined according to different needs and designs. For example, the oil tank capacity of Haichen injection molding machine model HCK360 is 400L, HCK410 is 500L.
Injection molding parameters
Injection molding parameters are key factors in the plastic processing process, directly affecting product quality and production efficiency. The main injection molding parameters include:
1. Melt Temperature: Melt temperature has a significant impact on product quality and can effectively reduce shrinkage marks and volume shrinkage.
2. Mould Temperature: Mould temperature has an important influence on cooling time and dimensional stability of the final product.
3. Injection Pressure: Injection pressure determines the ability of plastic to enter the mold cavity and usually needs to be adjusted based on material properties and mold design.
4. Holding Time: Holding time affects the density and dimensional stability of the product.
5. Injection Speed: Injection speed affects the speed and uniformity of material filling the mold cavity.
6. Cooling Time: Cooling time determines the time it takes for the product to be removed from the mold.
How do you calculate injection molding machine oil capacity?
The specific capacity can be selected by referring to the following formula: H=3.6s∗t/c
H is the hopper capacity (kg),
s is the weight of each shot (g),
c is the cycle time (seconds),
t is the drying time (hours)
The capacity of the hydraulic oil tank is usually related to the oil reservoir capacity of the injection molding machine, and whether an additional cooler is needed can be determined based on actual usage.
For example, Haichen injection molding machine with a 200-liter oil reservoir requires two barrels of pressure oil.
In the actual production process, the hydraulic oil system needs to be regularly inspected and maintained to ensure its normal operation and extend its service life.
If the oil temperature is found to be too high, the temperature can be controlled by increasing the oil tank capacity and equipping it with a suitable cooler.
The selection of hydraulic oil for injection molding machines is a relatively important link.
Whether the hydraulic system of an injection molding machine can work normally depends on the reasonable design of the hydraulic system, the manufacturing quality of machine components, and maintenance and use.
In addition, the hydraulic oil of the injection molding machine is a very important factor.
Oil capacity considerations for injection molding machine
According to the client’s requirement for oil capacity for the injection molding machine, we consider 5 points.
- Material type and molding cycle
- Cooling requirements
- Cleanliness and applicability
- Environmental conditions
- Overall performance of equipment
Material type and molding cycle:
The required tank capacity is determined based on the plastic material used and its molding cycle. It is usually necessary to ensure that the capacity of the injection plastic melt required in one injection molding cycle does not exceed 80% of the rated injection volume of the injection molding machine.
Cooling requirements:
Increasing the tank capacity and equipping it with a suitable cooler can effectively control the oil temperature, thereby ensuring the stable operation of the hydraulic system.
Cleanliness and applicability:
The cleanliness and applicability of hydraulic oil are important factors affecting the performance of the hydraulic system. Regular inspection and cleaning of pipes and tanks, and timely replacement of filters and hydraulic oil are necessary maintenance measures.
Environmental conditions:
For specific working conditions, the working medium needs to be explained or recommended for targeted design.
Overall performance of equipment:
In addition to the tank capacity, the performance parameters of the whole machine, such as the maximum drive power of the motor, the machine volume, and the weight, need to be considered.
The selection of the oil tank capacity of the injection molding machine needs to be based on multiple perspectives and a comprehensive evaluation.
