Factors To Look Into When Purchasing A Used Plastic Injection Moulding Machine

Finding the best used plastic injection moulding machine to purchase can be an overwhelming task. This is expensive equipment which means you have to consider your budget, the type and cost of machinery that you need. You will be wasting your resources if you purchase machinery whose capacity is more than you need. On the other hand, buying machinery whose capacity is lower than you need means you will not be in a position to serve your clients well.

Before shopping for the machinery, you will be required to determine what your needs are and how you expect to address them using the new equipment. It will be very disappointing to incur heavy investment that will not provide the required service. Careful research that might involve professionals is necessary to ensure the right asset is acquired.

There are various factors that can be used to select the right equipment to buy. The most common parameter many manufacturers use is the shot weight. This is usually measured in grams or ounces. Manufacturers can opt to use the injection volume or the measured shot weight as way of stating the shot weight of their machines.

Another important factor to consider is size of the equipment. Always match size of equipment to size of items to be moulded. Do not use large equipment to mould small items as they could get damaged. A lot of energy will also go to waste if you mould small items using large machinery.

In order to avoid quick degradation of the equipment, the temperature in the barrel should be lowered. Care should be taken to ensure it will provide service over an extended period of time. Since it is expensive, it should be used efficiently in such a way that the cost is recovered.

The third factor to consider is the clamping force of the apparatus. This force should be sufficient to keep the mould closed against the pressure of the cavity during injection. If the pressure is insufficient, it causes flash to arise at joints of the mould. Care should be taken to ensure the force is within the limits each item can handle.

There are various types of these machines in the market today. This is a factor that needs to be considered when making a choice of the equipment. Classification by type is done according to the driving system used in the apparatus. Before 1983 when the electric machines were introduced to the market, hydraulic presses were the only ones in use. While the electric presses had many advantages over the older ones, they are more expensive. Some of the benefits that you will enjoy with their use are speed, improved accuracy and production of less noise.

There is a new type of used plastic injection moulding machine in the market. It combines the best features of the earlier types. They however run like the standard machines consuming similar amount of power. Robots have been incorporated in the operation of the equipment.
